摘要
根据目前减排的理念,以某煤化公司的甲醇生产项目为依托,对在Shell炉粉煤输送中模拟CO2取代N2的工艺进行研究.采用平衡常数法研究体系中的复杂反应,通过部分简化建立模型,建立起CO2返回工艺体系,并考察了耗碳量,单位耗碳内的甲醇产量,出口有效气含量(CO+H2)的影响.通过模拟得到的结果表明,CO2返回工艺对各操作条件是有影响的,致使单位耗碳内的甲醇产量下降,但对于CO2减排却是有利的,而且合成气品质优于纯氮气的生产工况.以降低一定甲醇的产量为代价来减少CO排放,获得较好的社会效益是可取的.
Based on the current concept of CO2 reduced,the simulatuon of CO2 replacing N2 and the process of using CO2 for coal transportation in the Shell gasifier were studied according to a company＇s methanol production in a coal chemical project.The impact and variation of the situation in the process of CO2 back to Shell furnace on the system were estalished by means of equilibrium model of the complex reaction system and calculation model by part simplifies.The influence of consumption of carbon and methanol production within the unit consumption of carbon,as well as effective concentration of gas（CO＋H2） in exporting the content of the gasifier were investigated.The results of simulation showed that the process of CO2 back to the gasifier has an adverse impact on the operating conditions owing to methanol production declined in unit consumption of carbon,but it was beneficial for the reduction of CO2 emissions and the quality of syngas was better than those of N2 used.So The process of CO2 instead of N2 will enjoy a larger advantage in the future becauce of CO2 emissions reduction and better social benefits.
