Successful completion of follow-up assignment in Russia

CAC completes commissioning of newly built chlorine drying facility for AO Sayanskkhimplast and modernizes the existing sulphuric acid concentration

In spite of the pandemic-related circumstances that have had a major effect on aspects such as supply chains and travel, the project could be completed already with a successful test run following around eighteen months of planning and realisation.

AO Sayanskkhimplast, the largest Russian manufacturer of polyvinyl chloride, assigned Chemieanlagenbau Chemnitz (CAC) with the construction of a new chlorine drying facility and modernisation of the existing sulphuric acid concentration operations at the site of Russia’s first chlor-alkali electrolysis plant with membrane technology in Sayansk, Irkutsk region. The membrane electrolysis plant was planned and implemented by CAC in 2006 and was expanded in 2013 to enable an annual capacity of 180,000 tonnes of chlorine gas. “Sayanskkhimplast has been one of our longest-standing customers since our founding in 2004. I am very proud that in spite of numerous political and currently pandemic-related circumstances we have consistently managed to maintain trust-based co-operation and that we have once again contributed to the expansion of the leading market position of Sayansk,” states Jörg Engelmann, CEO of CAC.

With this follow-up assignment CAC undertook the basic and detail engineering, the supply of equipment, installation supervision and support during commissioning.
