HOUSTON (ICIS)--US propylene producer PetroLogistics has begun the restart process at its Houston facility in Texas, the company said on Thursday.
A company source said it expects the 544,000 tonne/year propane dehydrogenation (PDH) unit will be fully operational by the end of the week.
The unit was shut down on 22 April because a wiring connection on a gas generator separated and caused the generator to shut down, according to a filing with the Texas Commission on Environmental Quality (TCEQ).
The filing said the generator shutdown also caused the safety interlock system to shut down the plant, including utilities that supply steam to the main flare.
US spot prices for refinery-grade propylene (RGP) and polymer-grade propylene (PGP) were largely steady during the shutdown, sources said.
