Sulphur Block at Shantz, Alberta 2003
When prices are low, liquid elemental sulphur is poured into large blocks to solidfy (sulphur freezes at about 115C) on the prairie landscape for long term storage. Later, when prices are higher, it is remelted, prilled, and shipped to market (often to China). This block is near Cremona , Alberta, Canada. There are a couple dozen such blocks in Western Canada, mostly in the Rocky Mountain foothills, close to sour gas production facilities. The facility is operated by Shell Canada and stores sulphur from the Caroline Gas Plant to the west. The vertical wall here is about 25ft tall.
