Presently, the steam jet vacuum system is often applied in existing refining units of butyl acrylate devices. However, higher operating costs and more influence factors of vacuum fluctuation were found during the operation. In view of this situation, the feasibility of other vacuum units＇ application was discussed, the application of Roots-water ring vacuum pump unit was studied detailed, and the economics was also analyzed in this paper. The study provided reference for device bransformation in future.
