焦炉气的生产与利用及工艺螺杆压缩机的选择

摘要

阐述了炼焦过程中煤炭隔绝空气高温干馏出来的气体产物———焦炉煤气的生产与利用现状；阐述了焦炉煤气的传统及新型的利用途径，着重介绍了利用焦炉煤气制LNG的甲烷化和净化分离工艺及制氢新工艺、该利用途径带来的环境及经济效益、以及引入螺杆压缩机所带来的优势；并对制甲醇等工艺过程特点、市场供需形势做了简要叙述，并对焦炉气未来几年的发展空间作了预测。%The gas products out of coking coal in the process of air isolation and high-temperature dry distillation-coke oven gas and the production and utilization were introduced.The traditional and a new utilization way of the coke oven gas were expounded, focused on narrating the methanation and purification separation technology utilization of coke oven gas for LNG and new technology for hydrogen production, environmental and economic benefits generated from the utilization way.The advantages benefited by introducing process screw compressor into the technology, briefly elaborated the process characteristics of producting methanol process and the situation of market supply and demand, and the development space of coke oven gas in the next few years.
