In view of the composition characteristics and application requirements of the gas generated during clean and efficient utilization of coal through fractionation and purification, DKT has successfully developed a complete integrated technology for gas separation and purification (including impurity removal by pretreatment and TSA, sulfur-tolerant wide temperature shift, organic sulfur hydrolysis, water scrubbing for ammonia removal, MDEA desulfurization/decarbonization, fine desulfurization/dechlorination, catalytic deoxidation, acid gas desulfurization and sulfur recovery, hydrogen purification by PSA, methane concentration by PSA, CO concentration by PSA, and membrane separation), which has been successfully applied in many large-scale coal chemical projects in China and received unanimous praise from users.
Typical Process of Syngas to Ethylene Glycol (by-product: LNG)
Typical Process of Waste Gas to Hydrogen Production + Desulfurization
Technical features and advantages:
- Advanced and proven process, and safe and reliable operation;
- According to the conditions and requirements proposed by the user, the integrated technology can be flexibly configured to achieve optimal investment and energy consumption;
- Impurities in coal gas can be removed to a high degree, and the target product has high purity and high recovery;
- The plant has a high degree of integration and automation;
- The comprehensive energy consumption of separation and purification is low, while the economic benefit is high.
Application:
- Separation and purification of coal gas from dry distillation (coke oven gas, semi-coke gas, waste gas, etc.) and gasification gas (such as water gas, semi-water gas, syngas, etc.)
