Sumitomo uses new metallocene catalyst in LDPE plant

Increasing the capacity of an existing distillation process has been a major focus of the chemical process industry. On the other hand, entrainment flooding can occur as a result, which can create a bottleneck in the distillation process. This paper reports the results of a techno-economic feasibility study to debottleneck the distillation column using a proposed hybrid process combining a heat pump and thermally coupled distillation sequence. Fractional utilization of the area was used to identify flooding problems in the column as well as how much area is available for vapor flow on an existing stage. A heat pump aided thermally coupled distillation sequence (HPTCDS) was designed and optimized using a response surface methodology. Two cases were examined to test the proposed sequence. The results showed that the proposed sequence can achieve significant energy savings and remove the bottleneck problem.

Polyethylene quality control by automatic counting of gel particles

An important factor in determining the quality of ldpe film types is the content of gel particles in the film measured immediately after processing of the ldpe granulate.In the production of ldpe, gel formation is usually encountered only incidentally. The product quality of ldpe batches (100 to 200 tons) can be raised by spotting and placing apart the small quantities of ldpe granulate having a high gel content. To this purpose an inspection unit has been designed with as principal component the automatic gel counting device of DSM - Enraf Nonius.This paper describes several aspects of the inspection unit, with which some experience has been obtained in an ldpe plant, in which the unit has been installed on line with the product stream.
