Why is CNG called as clean fuel?
CNG is nothing but Compressed Natural Gas. It is made by compressing natural gas, to less than 1 percent of the volume, it occupies at Standard Atmospheric pressure. Natural gas…
LEAN OIL ABSORPTION
A gas with hydrocarbon vapors enters the bottom of an ABSORBER column, flows upward, and comes in contact with the counter-flowing LEAN OIL system. The LEAN OIL preferentially absorbs the…
What are NGLs?
NGLs or Natural Gas Liquids are heavy hydrocarbons which include ethane, propane, butane, iso-butane, and natural gasoline. These natural gas liquids have a high BTU ( British Thermal Unit) and…
Refrigerant Dehydration
Refrigerant is mainly a chloride or fluoride containing containning hydrocarbon in refrigerating plants. During refrigerant diffusion process, some residual moisture out of the refrigerant forms ice in the expansion valve…
Coating, Sealants , Adhesives
One of problems of Polyurethane Polymer is the moisture. If not removed, moisture will react with the isocyanate to form carbon dioxide gas and then leads to formation of bubbles…
Cryogenic Air Separation
The most common method for air separation is cryogenic distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. These components of air…
Natural Gas Dehydration and Sweetening
As raw nature gas normally contains saturated water, hydrogen sulfide, carbon dioxide and other impurities. These impurities should be removed as much as possible in order to meet the requirement…
Sulphur recovery process
The Claus Sulfur Recovery Process Sulfur recovery refers to the conversion of hydrogen sulfide (H2S) to elemental sulfur. Hydrogen sulfide is a by-product of processing natural gas and refining high-sulfur…
Process design overview for upgrading a gas-to-methanol facility
With the surge in natural gas production in the US, gas-to-methanol plants are receiving renewed interest. Not only are new methanol plants being built, but existing plants are also being…
Slurry
Slurry reactors are three phase reactors (solid/liquid/gas). Pictured below is a slurry reactor used in the production of polyethylene products. General Information Slurry reactors are three-phase reactors, meaning they can…
