| Abstract: | This paper exhibits detail studies on the causes of the methanol loss for a 450,000 t/a ammonia plant.Through improving and optimizing the device and process,adding an exhaust gas washing tower and a waste methanol collection system,reducing ammonia content in the feed gas,controlling the temperature of the Claus gas and the nitrogen flow for the stripper,the loss of methanol can be controlled below 0.5 kg per ton of ammonia production. |
