| Abstract: | The status of methanol/water separation system in Rectisol employed in the gas purification section for the process of ammonia synthesis with coke oven gas as feedstock is described and the scheme for retrofit suggested in which a part of lean liquid from the heat regenerator is taken as a reflux to the methanol/water separator whereas the methanol vapor from the tower top may directly be routed to the heat regenerator as a stripping medium;considering the components of coke oven gas being complicated a par... |
