| Abstract: | The production principle, process flow, investment and consumption of acetylene drying process by temperature swing adsorption with molecular sieve were introduced. The running situations of 2 sets of 400 kt/ a PVC devices adopting a mixed dehydration process and the above mentioned drying process respectively were compared. The results showed that the molecular selve drying process could reduce catalyst consumption, and in- crease economic benefits by 3 554 400 RMB ￥ per year. |
