Natural Gas Based CO2 Production Plant

Natural Gas Based CO2 Production Plant
Looking For Natural Gas Based CO2 Production Plant ?

MOS Techno Engineers Engineered Natural Gas Based Carbon Di-Oxide Production Plant produces food grade CO2 by burning Natural gas. Natural gas is one of the best raw material to make food grade CO2 as there is no precense of sulfhur.

The Natural Gas is burned under carefully controlled conditions in CO2 Generator and stripping section where the heat of the flue gases is transferred to the MEA solution. Once the heat transfer is taken place the gases are passed through soda scrubbing tower, where the remaining heat. CO2 from the flue gas is then absorbed into a highly efficient monoethanolamine (HEM) based solution in the Absorber Tower.  This Rich CO2 laden MEA which is subsequently heated in the initial process in the CO2 generator by the exhaust gases to release the raw CO2 gas. The CO2 is then led to a two stage, dry running (oil free) compressor to increase the pressure ( approx. 18-20 bar ). The CO2 is then passed through the Twin Tower Activated Carbon towers which function on a Cyclic basis where the ultimate purification takes place. The CO2 then passes thorough drying agent in an automatic twin tower molecular sieve drier. This CO2 is then feed into a Ammonia/Freon refrigeration loop to be Liquefied. The pure, liquefied CO2 can then be fed to a bulk CO2 storage tank.

Natural Gas CO2 Plant Benefit

FeatureBenefit
Flexible Layouts. Compact, modular component design means fast and easy installation and provides an economical use of available space, covering a variety of different layouts.
Burner Efficient, reliable combustion of dual fuel.
Inline Scrubber Water Recirculation and Treatment SystemDesigned to handle all the process scrubbing water, this system recycles, neutralizes and sheds the process heat from the water all in one circuit. This significantly reduces the volume of water discharged to drain, providing an economical and environmentally friendly water system.
Single Absorber TowerSpace saving, reduced complexity of design while still maintaining efficient absorption.
Process Towers LocationOption of indoor or outdoor installation of all process towers allows flexibility of layout in a variety of different situations. Outdoor location also reduces the required weather protection for the system.
Dry Running CO2 CompressorSpecially designed for use with CO2 gas, the dry running compressor means there is no possibility of CO2 contamination with oil.
Low Pressure Stainless Steel PurifierLonger residence time provides ultra-efficient NOx and H2S removal
Carbon Filter & “SP Media”A high capacity carbon filtration & “SP Media” column is installed in the CO2 gas inlet line to the compressor, to provide further assurance of pure and odour-free CO2
Centralized Control Panel and Panel viewAutomatic plant operation and panel view provide visual display and one touch read-outs of process data from a centralized position.
