Application of variable pressure liquid surface control in oil-gas two-phase separator
- Feb 02, 2018 -

When the liquid quantity and gas quantity of the oil and air separator is invariable, the liquid level stabilizes in a certain position, when enters the separator the liquid quantity or the gas volume changes, but causes the liquid surface to rise, the float linkage mechanism will make the natural gas control valve The opening closes small, the crude oil control valve opening is big, causes the exhaust quantity to reduce and the discharge quantity increases, The liquid level will be stabilized at a higher position until the liquid and gas levels of the separator are equal. When the liquid volume or gas into the separator changes, and the liquid level drops, the float linkage will make the opening of natural gas control valve open, crude oil control valve opening off small, so that the exhaust volume increased and discharge volume decreased, The liquid level will be stabilized at a lower position until the liquid and gas levels of the separator are equal. In this way, as the liquid or gas into the separator changes, the float linkage mechanism led the control valve to produce corresponding action, so that the liquid level to maintain relatively stable.
