March 05/2021 -


Dow Chemical has been resuming operations at its three crackers and its propane dehydrogenation (PDH) unit at Freeport, Texas, according to S&P Global. These crackers with a combined 3.2 million mt/year of ethylene capacity were shut in mid-February, 2021, because of very low temperatures in the region. At present, it is unknown when Dow's crackers in Freeport will be fully restarted. Dow Chemical shut its ethylene cracker No. 3 at its Plaquemine, Louisiana site with the annual production of 758,000 mt for expansion from mid-September to end-November 2016. After the restart this cracker can produce by 250,000 mt of ethylene more than before. Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).


This PDH unit with the capacity of 750,000 mt/year of propylene was taken off-stream on 16 February, 2021, because of very low temperatures in the region. Last year, Dow Chemical conducted a scheduled maintenance at its PDH unit in Freeport. Thus, the planned turnaround started in the week ended July 10 and lasted for 45 days. Propylene is the main feedstock for the production of polypropylene (PP).
