Gas recovery issues in atmospheric and vacuum distillation units
Thread Content
The gas generated by atmospheric and vacuum distillation units needs to be treated, as processing high-sulfur crude oil results in high sulfur content in this gas; burning it directly causes severe equipment corrosion. Therefore, it is necessary to desulfurize this gas, and it is important to know how to do so
The previous set of light hydrocarbon recovery units (absorption and stabilization units), followed by a desulfurization unit for the separated inlet gas. It is also possible to raise the pressure first and then send the gas to the catalytic absorption stabilizer before entering the compressor of the catalytic unit, and subsequently to the gas desulfurization unit.
I don’t want to use too complex processes; if it’s only subjected to a simple alkaline wash, is that the same as treating naphtha with an alkaline wash followed by water washing, and then burning it in a furnace – 2# fengdingwen
