Compressor oil-gas separator
Thread Content
I just started working at a petrochemical company. There is an old-fashioned American Siemens two-cylinder reciprocating piston compressor in the workshop, which is used to compress gas. After the gas comes out of one cylinder, it is cooled before going through a gas-oil separator. This separator has a float ball; could you please explain its separation principle? Thank you!
It is a very simple level control system; the other end of the float is usually connected to a spring or some lever-like mechanism that controls the opening and closing of the valve. When there is no liquid or only a low level in the separator, the float rises, but the force generated by the lever (or spring) at its other end is not sufficient to open the valve, so the valve remains closed； When the liquid level in the separator rises to a certain level, the float is also lifted to a corresponding height; at that point, the force exerted on the valve by the lever (or spring) becomes sufficient to open the valve.
