Valve & Automation supplies Sasol EPU 5 project

The Sasol ethylene purification unit, under construction at the Sasol Polymers plant in Sasolburg, is expected to go on stream in the second half of 2013 and will be ramped up to full capacity by 2015. The plant will enable Sasol to add value to its monomers feed streams originating from the Secunda complex and will boost ethylene production by approximately 48,000tns per year. The ethylene will be used in the manufacturing of polyethylene and will greatly benefit the plastics conversion industry in South Africa, which currently imports large quantities of this raw material.
