Two New PP Technologies Reduce Monomer Consumption
Recently, Shandong Dongming Hengchang Chemical Co., Ltd. has successfully developed two advanced technologies for vacuum recovery and cryogenic rectification in propylene recovery. These innovations have been recognized as reaching domestic leading standards following expert evaluation. The new processes were specifically designed to address the significant loss of propylene monomer during the polypropylene (PP) synthesis process in small-batch production.
This breakthrough technology is highly applicable to the small-batch polypropylene synthesis process as well as other polyolefin production methods. It enables efficient recovery of propylene gas that is typically released during the recycling stage of polypropylene manufacturing. By doing so, it significantly lowers the production costs of polypropylene while enhancing the safety of the production facility and reducing environmental impact.
The technology is not only mature and reliable but also easy to operate, offering both economic and environmental benefits. After thorough verification, it has been confirmed that there are currently no similar projects or achievements within the country. This makes Hengchang’s innovation a major milestone in the field of chemical processing and sustainable manufacturing. The company is now looking to scale up the application of this technology across its operations and potentially expand it to other related industries.
