Progress has been made in the polymerization process for Shenhua Ningmei’s polyoxymethylene project
Thread Content
On August 31, 2011, the 60,000-ton per year polyoxymethylene production project of Shenhua Ningmei Group successfully produced qualified pentaerythritol products, marking significant progress in the testing of the project’s most critical polymerization process. The 60,000-ton per year polyoxymethylene production project of Shenhua Ningmei Group utilizes a copolymerization technique that employs trimethylolpropane as the polymerization monomer. The unit for producing this monomer was successfully put into operation in May, and the mixing and granulation process has been adjusted to the point where it is ready for use; efforts are currently being made at full speed to adjust the trimethylolpropane synthesis facility.
LZ: Was the test drive successful? I heard that the production of polyoxymethylene is quite unstable.
Shanxi had previously tried to produce polyoxymethylene, but gave up due to cost and environmental issues; it was better to focus on downstream products of formaldehyde instead
