Highly sensitive IR SF6 pipes

Highly sensitive IR SF6 pipes

A sulphur budget for sour gas plants. Treesearch. Richard D. Rowe. 1976-01-01. The principal aim of this project is to produce a mass balance for the SO2 that is emitted into the atmosphere from sour gas plants in various localities in Alberta. Partial sulphur budgets for two plants at dissimilar locations are shown to exhibit major differences.
