What is LPG Vaporizer & Why it is needed?

In the global markets, the prices of fuels keep fluctuating. Cost reduction through LPG vaporizers can be invaluable for businesses with LPG applications. Also, the mechanism provided by LPG vaporizer manufacturers helps in safer consumption of LPG.

Liquefied Petroleum gases such as commercial propane or commercial butane are stored in the liquid state with the help of pressure control. But they need heat (energy) to change effectively into a gaseous state for safe consumption.

Insufficient heat due to insufficient vapour pressure can lead to wastage of the gas and result in system inefficiencies. That’s one of the reasons why LPG vaporizers exist. Read on to find out more.

To begin with, what exactly is an LPG vaporizer?
Simply put, it is a boiler through which LPG enters as a liquid and comes out as a gas. There’s more to a vaporizer. But, before that, let’s understand how the phase change works for LP gases.

To be able to use an LP gas which is in its liquid form, it needs to be moved from its storage vessel. Natural vaporization depends on ambient temperature and the tank specifications. The heat and heat transfer area of the tank affects the natural vaporization process. Also, if the gas consuming equipment doesn’t receive adequate vapor, it may not function properly.

LPG vaporizer manufacturers study the vaporizer efficiencies required by a plant and accordingly build a favorable mechanical system for industrial applications.

If vaporization isn’t consistent then…
You may come across frost on your tank which isn’t a good indication. The frost line is created due to a refrigeration effect that takes place when you consume the gas rapidly with a certain level of humidity.

Here, the heat that your system is providing for phase change is less than the actual heat being used for converting the liquid to vapor. The pressure reduction that takes place in the process leads to the refrigeration effect. Vapor pressure is affected due to this and managing your equipment can become difficult if there is a frost layer on the tank.

Generally, you would do the following for sufficient vaporization: 

Use additional storage tanks for increasing the vaporization capacity.
Increase the wetted surface area by trying to keep your tank full or increasing the size of your tank.
Try to work in compliance with laws and regulations that limit storage capacity in specific regions.

The difference an LPG vaporizer makes… A heaterless LPG vaporizer uses a heat exchanger to maintain the constant ambient temperature and required pressure in the system.
You can boost the capacity of your system with no need of adding extra tanks.
Use 100% of LPG in your tank and build a cost-efficient system.
Prevent situations such as re-condensation of vapor, tank “freeze-ups” etc.
Ensure continuous supply of vapor at temperatures below -40 Degrees Celsius.

What else does an LPG vaporizer do? You can reduce the electrical expense and carbon footprint due to the loss of energy that takes place because of conventional processes. Since there is no electrical heater involved in modern LPG vaporizers, you do not have to deal with the issue of a frequent electric heater failure.

Explore heaterless vaporizers that require low maintenance which makes it convenient to manage the system. If you are looking for a cost-efficient LPG vaporization solution, an innovative dry electrical vaporizer such as DRI-VAPO can be a smart option. DRI-VAPO utilizes an innovative technology for LPG vaporization that eliminates the need for using water or thermostat.

Top 7 Factors to Consider For Selecting the Best Safety Relief Valve

Safety relief valves or pressure relief valves ensure the safety of pipelines, vessels and equipment that deal with pressure-sensitive workflows. Unregulated pressure flow in such systems can lead to overpressure that can cause an explosion or cause damage to the machinery. To ensure the safety of personnel, equipment and other assets, you need to select the perfect valve from reliable safety relief valve manufacturers.

Here are the top 7 factors to consider while selecting a safety relief valve:

1. Size

Based on common usage, there are standard valve sizes offered by valve manufacturers. The orifice size should be selected as per the minimum required flow rate. You can pick a suitable inlet and outlet for the valve from the various size options available in the market. Valves are also available in flanged and non-flanged designs. Also, are you looking for a male or female connection? Filter your valve options as per the size requirements. If you are searching for a safety valve for specialised equipment then consider custom valve designs.

2. Set Pressure

A safety relief valve opens when it reaches the set pressure point. Ensure that your chosen valve comes with a set pressure as per your needs. Incorrect pressure settings may not give you optimum performance and can become a safety risk.

3. End Application

Safety valves are used in various industries. Based on the process fluids that will be passing through them, the valve material should be chosen. The valve should be able to function smoothly while allowing safe passage of elements such as air and water or process fluids that can be corrosive media.

4. Temperature

Many a time, the environment in which the safety valves are installed may involve extreme temperatures. You need to choose a safety valve that can withstand such high or low temperatures and does not interfere with the quality of the contents passing through it.

5. Capacity

Experienced safety relief valve manufacturers have standard valve capacity tables. Check if you can find a valve model with your desired capacity by referring to these tables. Else, you can think about customisation of the valves. Do not try to get a standard model if it doesn’t meet your capacity needs because it can be risky. The valve must relieve the process fluid at a certain capacity to serve its purpose.

6. Back Pressure

Depending on whether the fluid will move upstream or downstream, the back pressure needs to be decided. The back pressure is the pressure on the outlet side of the valve and can be constant or variable. Discuss your requirement with the valve manufacturer to get the back pressure right. If the back pressure isn’t right, the chances of getting the valve damaged quickly are high.

7. Quality

While you have got your tech specs right, the quality of your safety relief valve depends on the quality tests. Make sure that your chosen pressure relief valve manufacturers are able to provide you with all the quality test certifications guaranteeing the durability and safety functionality of the valves.

Everything You Need To Know About the LPG Vaporizers

LPG vaporizers are among the essential mechanical components for a number of commercial and industrial applications. Let’s get a basic understanding of the need for a LPG vaporizer, how it works, safety measures and other facts about LPG vaporizers.

Why do we need a LPG vaporizer?

Liquefied Petroleum Gas or LPG is a mixture of hydrocarbons, generally, propane and butane. LPG vapor is much denser than atmospheric air on earth and can easily catch fire. When exposed to air, LPG can be extremely harmful. Any leakage of the gas during storage or transportation can be risky so it is stored and transported in the liquid form.

The gas is generally stored under pressure in liquid form in a container. For safer consumption of LPG, its liquid form is converted into the gaseous form only when needed using a LPG vaporizer. The vaporization rate differs depending on the gas consuming equipment and the amount of vapor required to serve the purpose for the desired application.

Additionally, the vaporization of a compound depends on its chemical characteristics. External elements such as heat, atmospheric pressure, etc. can impact the chemical characteristics of LPG that lead to the changing phases from liquid to gas.

How an LPG vaporizer works?

A LPG vaporizer is basically a boiler or heat exchanger that is connected to LPG systems where the end user can utilize the LPG after the liquid to gas phase change takes place in the LPG vaporizer component.

ReputedLPG vaporizer manufacturers produce vaporizers that can handle large quantities of LPG and are designed to meet the requirements for a variety of applications. Vaporizers can be connected using safety relief valves to control huge amounts of LPG every hour without the need for investing in a large number of tanks. LPG filling stations installation is all that is required for supplying LPG to a huge area such as a residential complex or a commercial zone.

Hazards due to leakage can be prevented in the LPG pipeline as the gas is formed only after the liquid passes through the LPG vaporizer. Vaporizers also ensure zero wastage of the LPG and lead to cost savings.

Safety precautions in LPG Vaporizers

It is a fact that LPG, when exposed to air through possible leakages, can be catastrophic. Water is heated in the LPG Vaporizer to generate heat for a phase change. The electrical parts used in the vaporizer are safely placed in a flameproof enclosure. To ensure safety, LPG Vaporizer manufacturers include high-quality safety valves that stop the LPG liquid supply if the water temperature in the vaporizer falls below a set temperature. In case, the water temperature gets past a set temperature, the water heater connection is immediately cut off.

Established LPG vaporizer manufacturers have the capabilities to customize standard LPG vaporizers and offer tailored components as per the specific project requirements of clients.

What is the purpose of a pressure relief valve?

There are several industrial mechanisms where pressure plays an important role. To control the pressure in many of these mechanisms, a pressure relief valve produced by safety relief valve manufacturers is sought.

Pressure Safety Valve (PSV), Relief Valve and Pressure Relief Valve (PRV) are different names of a safety valve, a component used for controlling pressure. The PSV is used mainly in industries such as chemicals, petrochemicals, natural gas processing, etc.

Ensure safety with a pressure relief valve

The pressure relief valve is a safety valve that keeps the pressure within safety limits to prevent equipment failure, mishaps or other undesirable outcomes. Pressure relief valves are designed with controls to increase or decrease the level of pressure in a pressure vessel.

The safety relief valve ensures safer management of the environment if excess of pressure or overpressure situation occurs wherein the pressure increases beyond the Maximum Allowable Working Pressure (MAWP). The excess pressure generated is diverted into a safer outlet through an auxiliary route.

An automatic safety relief valve also functions effectively in the absence of a power by tracking the process fluid movement in the pipeline. For example, even during a power failure, the LPG passing through a LPG pipeline can be automatically shut off with the help of a functional safety relief valve if excess liquid flow is detected in the event of a leakage in the line.

For the safety valve to deliver optimum performance, it should be installed and maintained properly. Use of a pressure relief valve with an incorrect size can also lead to damage to life and property in the vicinity. Pressure relief valve manufacturershave to run a number of tests to design and build the valves with the right specification.

Finding the right pressure relief valves

Depending on the contents to be passed through the valve, the material of the valve can be decided. Materials such as Stainless Steel, Brass and Carbon are some of the material options. Although there are standard valve sizes available in the market, the valve can be custom-designed along with desired end connection types to get the right fit for the intended mechanism.

Pressure relief valve manufacturers usually have a team of engineering design experts who discuss the requirement with the client for customised valve designs. Depending on the application, a pop action safety valve or angle type discharge valve can be used. The pressure range can be customised as per the specifications of the pressurized area. High quality pressure relief valves require low maintenance and therefore, lead to minimal costs.

For pipelines carrying LPG and other gases, safety risks are averted by using valves. Whether it is an industrial plant, a commercial space or a residential complex, reliable safety relief valve manufacturers are well-equipped with the necessary infrastructure and the teams to ensure minimum wastage of energy and maximum safety in handling of contents.

Certified valves are provided by expert manufacturers who study the requirements of the clients and offer a cost-effective solution with the necessary test certificates from industry-recognized certifying agencies. For reliable safety relief valves, get in touch with AEPL at www.aeplglobe.com.

What are the Challenges & Opportunities in the LPG Market in Bangladesh?

Among the developing countries, the economy of Bangladesh is growing at a rapid pace with a growth rate of 7.2%. LPG tank manufacturers are in demand to push the LPG demand in the country.The demand for LPG has increased at an exponential rate of 60%. The reason for this sudden rise is the suspension of natural gas connections in the country. But along with opportunities there are numerous challenges for the LPG market in Bangladesh.

Challenges in the LPG market in Bangladesh:

At the moment, Bangladesh has a LPG supply capacity of 4,00,00 MT/year which is way less than its enormous demand of 1.5 million MT/year. In the next five years, experts estimate a 400% growth in the LPG sector in Bangladesh. Although there are government initiatives to support the LPG industry, the biggest challenge to the LPG market is that the supply cannot keep pace with the demand in the industry. It will take time for investors in the LPG space to set up the infrastructure and reach out to all the areas where there is demand. A plan for LPG tank installation, LPG filling stations installation,LPG bottling plant, LPG service lines and other details to transition from CNG to LPG is necessary for carefully tackling the challenges faced by the LPG market in Bangladesh.

Opportunities in the LPG market in Bangladesh:

Initially, the Bangladesh government served its people with CNG which also included import of fuel to meet the demand in the country. But now natural gas has become scarce and costly. It will be completely depleted by 2022-2023 if new gas supply capacity isn’t added to meet the increasing demand for fuel. In the recent years, in view of the growing energy concerns, the regulatory authorities of Bangladesh took decisions to promote LPG consumption in the country.

According to an industry report, the energy division of Bangladesh estimates a gas demand of 8,000 MMCFD by 2041. Hotels and restaurants are one of the major energy usage sectors in Bangladesh. CNG will not be available for long for this sector as well as other commercial use sectors such as agriculture, lighting, metal and more. LPG will be the ideal clean alternative for catering to energy demand for commercial applications.

Some of reasons that have led to opportunities in the LPG sector are as follows:

• Rise of entrepreneurs in the country

Economic growth, higher literacy levels and women empowerment has led to more and more entrepreneurs in Bangladesh.

• Wealthy population with increase in the income

As per statistics, the per capita income of Bangladesh is expected to increase to US$ 1,752. The growing income is turning Bangladesh in to a middle-income country. LPG will become affordable for the financially secure citizens of the country.

• Increasing use of LPG as an auto fuel

In Bangladesh, more than 1,000 auto gas station licenses have already been awarded by the government to promote the use of auto fuel. The target is to convert 2,50,000 vehicles into vehicles running on auto gas.

• Tax benefits

The Bangladesh government provides tax exemption on import of LPG. Also, LPG equipment can be imported to Bangladesh at 2% less tax than the normal tax rates.

Economic growth in India is propelling the growth of the LPG industry in the country. There is a rise in the LPG filling stations installations and LPG bottling plant installation.

Today, the LPG industry is divided into industrial, commercial, transports and domestic segments. As per a recent report, Indian consumers use 21.2 million tons of LPG of which 90% is used as cooking fuel. In the midst of concerns such as global warming and sustainable energy needs, LPG is a clean gas which can have enormous significance in the country.

Some of the key challenges in the LPG sector are as follows:

• Correct Positioning

LPG is a clean burning energy that consists of 60% natural gas and 40% fossil fuels. Among other energy sources such as petrol, kerosene and diesel, the positioning of LPG should be that of a clean energy. The multiple applications of LPG as a green fuel or clean energy should be highlighted to promote its usage.

• Cost of storage, transport and distribution

To meet the demand in remote areas, the transport infrastructure should be in place. But there are still many regions where transportation costs for LPG is high and it becomes difficult for LPG service providers to manage the supply. LPG requires specialised equipment such as LPG tank installations to store it, package it and distribute it.

The returns from the industry should justify the investments for LPG service providers to open more LPG service centres and for more people to have easy accessibility to LPG. There is a need for initiatives that will make LPG businesses safe and sustainable for entrepreneurs and affordable for end users.

• Quality of alternate energy sources

Earlier, the quality of LPG was competitive compared to petrol and diesel. But research has improved the quality of petrol and diesel. The quality edge that LPG industry once had isn’t working for it anymore.

• Transition for consumers

Consumers who have been using traditional sources of energy such as firewood, coal, and others need time to adapt to the use of LPG. Adequate awareness is required to educate these users about the benefits of LPG and the ways to safely use it. Awareness will help members of the LPG industry to tap into different markets and boost the growth of the LPG industry.

Competitive pricing, cleanliness and efficiency are determining factors for people to choose a specific energy for usage. Rising income and mobility between rural and urban areas also has an impact on the energy usage behaviour in the country. LPG Tank manufacturers and other businesses operating in the LPG sector along with industry bodies and government initiatives are trying to change the perception of potential consumers through promotional messages.

As per an industry report, in 2016-17, 33.2 million households were enrolled in to LPG usage in India through the Pradhan Mantri Ujjwala Yojana. Government initiatives like these have led to an increase in the LPG tank installations in India and are trying to ease the difficulties in the LPG sector. The LPG penetration into rural areas is changing the fuel usage behaviour in the country.
