Goodbye Nevis Gas Plant
I just found out that the Nevis Gas Plant was shut down in 2019. Its 25 km west of Stettler and processed sour wet gas and oil from production facilities around the Stettler area. It was built in 1956 as a conservation project ( thats what it said on the original plant manuals) as the gas had very little value but the government wouldn't allow flaring. Crude at that time was about 3.00 per barrel, gasoline $ 0.06 per liter. It was a small but complicated plant. It had 2 amine trains to sweeten the gas with 3 sulphur trains to convert the H2S to elemental sulphur. There was a refrigeration circuit to condense the hydrocarbons out of the gas. An oil absorbtion train circulating cool oil to further separate hydrocarbons. Then there was a distillation unit to take the liquid hydrocarbons and separate them into propane, butane and condensate. It produced 120 mmcfpd natgas, 300 tpd sulphur, 80,000 gpd propane 20,000 gpd butane and 1500 bpd of condensate. And of course there were boilers, a firewater system, water treatment plant, etc. No power generation, it was dependent on the grid.It was built by Gulf Oil and owned by Keyera when shutdown. I worked there from 75 to 79.The point is that Central Alberta is drying up as all other fields will. Its still there today but will take extensive environmental reclamation to return to nature.
