Optimization,Improvement and Application of Methanol Distillation Process Technology for Coke Oven Gas Production
In order to solve the technical problems of severe gas pollution and poor energy-saving effect in the traditional coke oven gas to methanol distillation process,it was decided through technical research to modify the heating process of the distillation reboiler and treat the non condensable gas in the distillation section during the coke oven gas to methanol distillation process.The practical application results showed that the modification of the distillation reboiler heating process reduced the equipment heat transfer load and the temperature difference of the chiller was reduced to 50℃.After the treatment of non condensable gas in the distillation section,the recovery rate of non condensable gas and liquid has been improved,the emission of polluted gas has been reduced,the economic benefits have been improved,and significant application results have been achieved.
