Impact of increased propane content in propylene feedstock on the operation of polypropylene plants
Thread Content
Hello, dear colleagues in the marine industry: I would like to ask whether an increase in the propane content in the propylene feedstock used in the production of small-scale polypropylene affects the operation of the manufacturing plants Imported raw materials are used, and recently the amount of catalyst used in production has increased to over 100 grams; the reason for this has not been identified. Testing was conducted on the propylene feedstock, and the analysis results showed that the propane content was as high as 18,000 ml/m3. I would also appreciate it if you and industry experts could help analyze whether an increase in propane content is the cause of the abnormal production and the increased amount of catalyst used.
Although propane does not participate in polymerization, an increase in propane content is equivalent to a decrease in the substrate concentration.

The purity of propylene is 98.2%, and logically this should not affect propylene polymerization; it must be other factors at play, such as water, oxygen, sulfur, heavy metals, dienes, and carbon monoxide – all of these should be checked. .
