RE: No flare BUT tankers30 Nov 2020 18:40
Contrary to what Troll2 would have you believe I work in the offshore oil and gas industry, and have actually been inside a good number of separators on various north sea platforms, it will be slightly different for onshore but the basics will be the same, the fluids, gas and quite often small particles of sand come up from the well and hit the separator inside the separator starting from the ceiling there will be the inlet end which will have a gas scrubbier at height which will involve a series of a bank of vain packs, which filter any impurity’s from the gas, the gas will head for the flare, then we drop down a level just below the gas vain packs will be one in a series of weir plates that acts as skim levels for the oil that is floating above the water, what ever the water cut, it is straight forward the oil floats on top of the water and heads to another vessel and then on towards the hydrocyclones where the last water and impurity’s are separated to keep the oil content below the legally acceptable level before the produced water enters the sea, what’ left below the weir plates is sometimes an oily sludge, there is a system in place on the floor of the separator called the sand wash and every so often the vessel is shut down and a sand wash begins, where water is introduced to the bottom of the vessel through a series of sparge bars and everything in the vessel is agitated and the skimming process begins again with volumes of water to flush sand or any deposits out, not sure how it actually works onshore but as I said the basics will be the same...But no gas would equal no oil, unless there is some new gas diverter system for onshore(maybe gas to wire) that we haven’t heard about.
