Recently, Shandong Dongming Hengchang Chemical Co., Ltd. independently developed two technologies for vacuum recovery and cryogenic rectification propylene recovery, which have reached the domestic advanced level after expert appraisal. These two new processes are a new process developed by Hengchang Company for the loss of large amounts of propylene monomer in the polypropylene (PP) synthesis process of the small-bulk process.
The process can be widely used in the small-bulk polypropylene synthesis process and other polyolefin synthesis processes. It can effectively recover the propylene gas discharged from the recycling process in the polypropylene production process, greatly reducing the production cost of polypropylene, and effectively increasing polypropylene. The safety factor of the production plant, while reducing environmental pollution. The technology is mature and reliable, easy to operate, economic and environmental benefits. After verification, there are no similar projects or achievements in the country.
