Kurzbeschreibung (Abstract)
A decision framework is presented to minimize the number of distinct ISO 2858 compliant standard chemical process pumps in an equipment pool. Two model variants are introduced: (i) the set cover problem to find the minimum number of ISO-sizes required to meet a given set of specifications, and (ii) the maximum coverage problem to allow for a tradeoff to be made between application coverage and equipment variety in the pump pool. A case study is carried out in cooperation with Evonik Operations GmbH applying the framework to a real-world data set; the results of which suggest significant potential to rationalize pumping equipment. Numerically, the decision model(s) were found tractable and thus readily applicable for industrial scale analyses. By including an established model of centrifugal pump operating ranges taken from a dimensioning tool developed at German chemical industry association VCI, we eliminate the need for specialized software and minimize equipment-data requirements.
