Abstract

The present invention relates to a process equipment matched with cold-tube type low-pressure synthesis tower. It adopts two production systems which can be series-connected or parallel-connected to make production. First stage adopts shell and tube type (or cold-tube type) synthesis tower and rear stage adopts cold-tube type (or shell and tube type) synthesis tower, also can completely adopt cold-tube type synthesis tower. Every synthesis tower can be an independent system respectively, and the described cold-tube type synthesis tower type can be single-tube baffled type and U-shaped tube type. Between two synthesis towers are mounted pipeline and valve for make regulation.
