Storm Uri which blanketed the southern states of the US with snow, and led to widespread power outages in Texas, has had a major impact upon US Gulf Coast and Southern-Midwest refined products supply. Most Gulf Coast refineries were shut down or forced to operate at reduced rates. IHS Markit estimated that more than 5.2 million bbl/d of Gulf Coast capacity and 730,000 bbl/d in PADD 2 was impacted by the winter weather at its height, and close to 20% of lower 48 US natural gas production was shut-in in the first half of February. A drop in crude oil production of between 2.2 and 4 million bbl/d was estimated.

Start-up, shutdown and turndown

With the ongoing changes in gas field and refinery feedstock compositions, many sulphur recovery units around the world are facing turndown scenarios to such an extent that it is difficult to meet stringent environmental regulations. Equipment and instrumentation behave differently under turndown conditions, and not always in ways that are desirable. Start-ups and shutdowns can place demands on the equipment that are more severe than years of normal operation. In this article, Optimized Gas Treating, Sulfur Recovery Engineering and Comprimo share some of their learnings and experiences of these scenarios.
