What are the main applications of oil-injected screw compressors?
Thread Content
Are oil-injected screw compressors mainly used in the refrigeration industry? What is it mainly used for in the oil industry? Is it necessary to install a filter separately?
Compressors are not only used for cooling but also for compressing gases in the petrochemical industry
I work in the oil industry, dealing with reciprocating compressors and dry screw compressors; I have seen some papers on refrigeration using oil-injected screw compressors. Because oil-injected screw compressors can result in oil in the gas, and although they can achieve higher pressures than dry screw compressors, they seem to be suitable for medium and low pressures as well as low flow rates; therefore, I wonder where oil-injected screw compressors are used in oil fields? Is it commonly used?
Injection screw compressors are widely used in the chemical industry for gas recovery from gas tanks.
You’re right – the pressure of screw compressors that use injection technology really can’t be too high. They are generally used for low-pressure applications, with high-pressure uses being quite rare. The screw compressors in our facility are used for refrigeration purposes, and it’s very necessary to install filters in front of these units. Screw compressors aren’t piston compressors after all; their gaps are extremely precise. In piston compressors, it’s not a big issue if there’s a little dirt present, but that’s not the case with screw compressors. Screw compressors usually don’t break down easily, but when they do, repairing them is complicated, and in some cases it’s necessary to send them back to the manufacturer
Injection screw compressors are used in a variety of applications, but they are basically not used in the air separation industry
The refrigerators used in the air separation industry are generally oil-injected screw types
Injection screw compressors have a wide range of applications; the refrigeration industry is just one of them. They are widely used in the field of chemical gases, especially as oil separation technologies improve.
Gas used in small factories; it is widely used in small nitrogen production facilities
With the advancement of domestic screw compressor technology, its application areas are gradually expanding to fields such as refrigeration, natural gas and shale gas extraction, as well as the recovery of chemical process exhaust gases
