Different Types of Gas Plants: Uses & Benefits

 Greenhouse gas emission has always been one of the hot topics across the globe – which is still being taken care by the manufacturers of Gas Plants. With utilizing cutting-edge technology, these plants are consecutively improving their operations to reduce emission of CO2 gas & other planet-threatening gases into the environment.  

In order to reach the depth of this topic, explore the hidden gems in this 3-minute-read blog. There are different types of Gas Plants, such as:

1. Gas-fired power plant or natural gas power plant: This plant burns the natural gas & utilizes the stored chemical energy to successively convert the energy into electrical energy to generate electricity. They have high thermodynamic efficiencies Its two types are:

a. Simple cycle gas-turbine: Also known as open cycle gas-turbine (OCGT) is a gas turbine to produce electricity. It is the cheapest plant to build & run, but has lower efficiency.  

b. Combined cycle gas-turbine (CCGT): Its efficiency ranges up to 55% & is highly efficient when compared to the latter one. 

2. Nitrogen gas plants: This type of plant either uses Pressure Swing Adsorption (PSA) or Membrane technology to produce 98% to 99.999% high-purity nitrogen gas by separating nitrogen from the ambient gaseous mixture. Both are cutting-edge technologies:

a. PSA technology: It is the most efficient technology widely used to produce high purity nitrogen gas. It takes in ambient air in its chamber, compresses & then filters the air. When the filtered air passes through CMS (Carbon Molecular Sieve), all gas molecules like oxygen, CO2, argon & others get trapped, leaving only nitrogen gas as the only gas component. 

b. Membrane separation technology: When filtered air passes through hollow porous fibres, all gas molecules & water evaporates, leaving nitrogen as the only gas molecule. However, PSA is more preferrable over this technology. 

3. Oxygen gas plants: Operated via PLC (programmable logic controller), this plant utilizes PSA technology to separate oxygen gas from the ambient mixture. The modern model is highly energy efficient, cost-effective, & equips enhanced failure safety measures.

4. Medical oxygen plants: Automatic medical oxygen generator utilizes the well-known PSA technology to generate oxygen onsite. This can produce & store oxygen gas in bulk in high-pressurized vessels to provide oxygen at required intervals. 

5. Air separation gas plants: This plant utilizes fractional distillation method to separate atmospheric air into its different components, such as nitrogen, oxygen, & sometimes other gases like neon, krypton, argon, & xenon. In order to separate pure gases from ambient air, it uses:

a. Cryogenic distillation process: This process aids in separating different high purity gases by liquification & distillation of the ambient air. 

b. Non-cryogenic distillation process: This process aids in separating only one high purity gas, such as oxygen or nitrogen, from the ambient gas.

Benefits of Gas Plants

The worth of a product is measured by its offered benefits to the user, & industry at national & international level. Such advantages of Gas Plants include: 

1. Energy efficient: These gas plants are designed in a way to consume low power, yet offer full-fledged benefits.

2. Automatic control: Automatic gas plants run via PLC – a computerized control of operation which offer error-free operation at fastest rate. 

3. Cost-effective: These plants are manufactured with good-quality material & supplied at comparatively low price from conventional methods.

4. Service life: The average lifespan of gas plants ranges over 20 year due to the incorporation of enhanced failure safety features. 

5. Fast production rate: The modern model is highly efficient & offer high production rate. 

Now, as you know about different types of Gas Plants, find your way to utilize these shreds of information to raise your business bar above expectations. Explore a list of best gas plants manufacturers, suppliers & dealers for buying in India. 

How Profitable Is On-Site Air Separation Plant?

From medical to metallurgy, industries engaged with manufacturing & producing products require bulk gases imperative to their whole operation. To achieve a certain goal, everything needs to be on track to prevent risk of accidents or faulty operation. That’s when an Air Separation Plant come into the play.

Industries either purchase gases in bulk from other industries or produce gases on-site by themselves. According to several evidences & proven facts, it is being said that on-site production of gases offers multiple benefits, such as consistent purity delivery, lower operating costs, high efficiency & reliability.

As Air Separation Plant becomes an increasingly reliable fixture to be installed in various different types of industries, you may be wondering about how the plant functions, what are the methods utilized to generate different kinds of gas, & what does it offers to the users. In this 3-minute-read blog, you may find untold truth about this plant.

Working Principle of Air Separation Plant

An Air Separation Plant uses fractional distillation method to separate the ambient mixture into its components. It uses distillation process to separate the mixture by heating them to a temperature at which one or multiple parts of mixture will vaporize. This plant separates atmospheric air into its primary component parts, merely oxygen (O2) & nitrogen (N), & sometimes other gases also like argon, neon, xenon & krypton. 

This plant uses either of the two methods i.e., cryogenic distillation process & non-cryogenic distillation process, to separate pure gases from air. Different high purity gases can be separated from the atmospheric air by liquification & distillation via cryogenic method. But, only one high purity gas, like oxygen & nitrogen, can be separated from air via non-cryogenic distillation method.

Non-cryogenic processes include two best technologies i.e., 

    • Pressure Swing Adsorption (PSA): It utilizes the fact that under high pressure, different kinds of gases tend to be attracted to absorbents. Typical absorbents are Typical adsorbents are activated carbon, zeolite, silica gel, alumina, & resin. To produce oxygen or nitrogen, it takes in ambient air, compresses & filters the air. The compressed air passes through the chamber containing an adsorbent bed which attracts all gas molecules, leaving only one gas (for instance, oxygen) to flow further. This one cycle produces 98% pure oxygen gas, while the second cycle can produce 99.9999% pure oxygen gas. 

    • Vacuum Swing Adsorption (VSA): It separates certain gases from the gaseous mixture at near-ambient pressure while also apply a vacuum to the purge gas. However, PSA is the most recognized & renowned method of all. 

Vast Applications

An Air Separation Plant is used in numbers of applications because of its offered enormous benefits at low operating cost. Such industrial applications include medical, metal production, waste management, pharmaceutical, fish farming, oil & petroleum, chemical & petrochemical, metallurgy, electronic, water treatment & several others. 

Benefits & Features

The worth of a product is evaluated by its properties & offered range of advantages. Such advantages of an Air Separation Plant include:

    • Energy efficient: Manufactured utilizing cutting-edge technology, this plant consumes less electricity than conventional methods.

    • Easy installation: The installation process requires less human energy. It utilizes less space. 

    • Automatic control: The plant functions automatically via PLC (programmable logic controller) which ensure zero human error & no technical faults.
