EMS-Chemie relies on Atlas Copco compressors and expertise
Wilrijk, Belgium, April 2014. The Swiss chemical group EMS-Chemie, an industry leader in the speciality chemicals and polymer materials field, has put its trust in Atlas Copco. In 2012 Atlas Copco supplied two type ZH 15000 oil-free centrifugal turbo compressors, including dry coolers and pumps, for a new cooling-water circuit. The units provide compressed air for the plant air supply and for nitrogen production at the Domat/Ems production site. Atlas Copco also consulted on the ideal solution for optimizing the site’s infrastructure.
Tailor-made solution for air and nitrogen production
The needs at the Domat/Ems production site are enormous. Every year 74,000,000 Nm3 of compressed air is required for the plant air supply and 69,000,000 Nm3 for the production of nitrogen. In 2010 it became apparent that the existing systems were approaching capacity and would be unable to meet production requirements much longer. When one of the six compressors broke down, EMS-Chemie engineers questioned the existing concept as well as the planned capacity increase. They investigated a redesign of the entire system and contacted Atlas Copco to obtain a tailor-made solution to suit their needs and to optimize the entire infrastructure. The existing unit consisted of two turbo compressors and four old oil-free reciprocating compressors that supplied the two compressed-air networks operating at different pressure levels (plant air and nitrogen production). The two turbo compressors, one from another supplier and a type ZH 10000 geared turbo from Atlas Copco, were retained to ensure security of supply and because they complemented the two new type ZH 15000 geared turbo compressors.
“We prepared a complete parallel system and then swapped over the unit, one machine at a time, ensuring that round-the-clock production was maintained.” explained Josef Wolf, Project Manager at EMS-Chemie. “With Atlas Copco at our side, we had an outstanding partner who always came up with a solution when problems were encountered.”
