Abstract

The article presents information on the regeneration of filter elements (filter components) made of tin-phosphorus bronze powders that were tested during polyethylene production in the unloading unit of the ethylene polymerization reactor for cleaning hydrocarbon compounds from polyethylene powder particles. It was found that during the testing period, the filter elements met the requirements specified in the equipment regulatory documents. After completing the tests, two thermal regeneration cycles were carried out: at LLC “Stavrolen” and at O.V. Roman Powder Metallurgy Institute. It was found that in the first case, the filter element throughput was restored to 67.5% of the initial value, and in the second case, to 97.2%, which indicates the multiple regeneration possibility of spent powder filter elements when used to clean hydrocarbon compounds from polyethylene powder particles.
