NEW YORK (ICIS)--By the end of this week, US-based Stepan expects to start its planned shutdown and converter recatalysation at its 90,000 tonne/year phthalic anhydride (PA) plant in Elwood, Illinois, a company official said on Tuesday.
The plant will be shut down for one week, the official said.
In the following four weeks, one of its three converters will be recatalysed while the others will remain on.
Meanwhile, Koppers has restarted its 100,000 tonne/year PA plant in Stickney, Illinois, after a month-long turnaround and recatalysation that started in mid-September.
The Stickney plant is running well, and the typical ramp up of new catalyst is underway on two reactors, said a Koppers official.
PA is a key intermediate in the production of plasticizers, which are used to make products such as flexible polyvinyl chloride (PVC). PA is also used in unsaturated polyester resins (UPR).
Major US PA producers include BASF, ExxonMobil, Koppers and Stepan.
