In view of the characteristics and application requirements of the gas composition produced by the clean and qualitative utilization process of modern coal chemical industry, a complete integrated gas separation and purification technology has been successfully developed (including pretreatment, temperature swing adsorption, TSA decontamination, sulfur-tolerant wide-temperature shift, organic sulfur hydrolysis, water elution ammonia, MDEA desulfurization/decarbonization, fine desulfurization/dechlorination, catalytic deoxygenation, acid gas desulfurization and sulfur recovery, PSA extraction hydrogen, PSA concentration methane, PSA concentration CO, membrane separation, etc.) It has been successfully applied in many large-coal chemical projects in China and has been well received by users.

Typical process flow of synthesis gas produces ethylene glycol (by-product LNG)

Typical process flow of raw gas produces hydrogen production + desulfurization

Typical process flow of gasification gas produces hydrogen + synthesis gas (adjustable hydrogen to carbon ratio) + desulfurization

Technical features and advantages

µThe technology is advanced and mature and at the same time safe and reliable operation

µ According to the user's working conditions, there is flexible configuration of integrated technology and besides optimal investment and energy consumption

µ The impurities are highly purified of gas,and subsequently target products are highly purity and yield

µ The devices are highly degree of integration and automation

µ Separation and purification of the comprehensive energy consumption is reduced, and the economic benefit is elevated

Application field

Separation and purification of dry distillation (coke oven gas, semi-coke gas, waste gas, etc.), gasification gas (such as water gas, semi-water gas, synthesis gas, etc.)
