By-Products

Established to cater the needs of engineering to look after the integral part of the coke making process. In the process of converting coal into coke, the volatile matter in the coal is vaporized and this volatile matter results in a liquid condensate stream and a gas stream. The functions of the by-product plant is to recover by-product coal chemicals and to condition the gas so that it can be used as fuel.

Technology

• Gas processing & Primary coal chemicals recovery plants.
• Secondary coal chemical processing, other chemicals, petrochemicals based on process licensor’s know how.
• Up scaling of pilot plant to commercial scale plant based on study conducted by clients.
