BC Insight conference reporting noted March and later September storm disruptions to North American sulfur logistics in 2021 alongside recovering US refinery utilization. Temporary outages tightened regional molten availability even as global recovered sulfur supply remained structurally adequate for the year. The wrap is at https://www.bcinsight.crugroup.com/2022/01/31/sulphur-sulphuric-acid-2021/.
Winter Storm Uri's February 2021 Texas freeze is the US Gulf event in the same winter, even if the conference sentence names March and September. Refinery and gas-plant outages cut recovered sulfur when fuel demand was already healing. Temporary tightness in molten is a Tampa story. USGS Tampa climbing from about $69 toward $192 by mid-June is consistent with supply issues after pandemic cuts plus storm outages. USGS later said high 2021 prices reflected supply issues rather than a permanent demand boom.
Alberta recovered sulfur still leaves mainly through Vancouver. Canadian storm disruptions to rail and forming are a Sultran-and-Heartland story: gondolas, not Claus. A March outage that delays a unit train delays a Port Moody loader. It does not change Canada's 4.9 million tonne recovered year. It changes a week's molten and solid availability. September's later storm is a second temporary tightness inside a firming second half.
Recovering US refinery utilization is the other half of the conference sentence. Fuel demand healing adds Claus tonnes after the storm. Two arrows in one year: outage tightness, then output recovery. 2022's elevated Gulf refining into fading phosphate demand would be the surplus version. 2021 is the tightness version.
Europe's German sour-gas decline, in the same conference notes, is structural. North American storms are weather. Both raised interest in seaborne and rail sulfur for acid plants. Canadian molten rail into the US, USGS 73 percent import share for 2017-20, is the rail answer. Vancouver granules are the seaborne answer when FOB pays.
Tampa about $83 in early January, BC Insight, toward $192 in mid-June, is the contract path these outages sat on. Licensed weekly grids are not restated. The March and September storm note is BC Insight conference language, not a NOAA incident log reprinted here.
Heartland's 30 June tank, completed after the winter storms, is storage that buffers the next outage. Forming and tankage are how a recovered-byproduct corridor absorbs weather. Nameplate is not.
Figures follow BC Insight. Late-winter and September 2021 storm disruptions are the North American logistics-tightness chapter under a recovery-year Tampa.
