摘要： An oil-feed-type air compressor includes a compressor main body driven by an electric motor, a separator that separates the oil from compressed air delivered from the compressor main body, an oil supply system that supplies the oil separated by the separator to working chambers of the compressor main body, an oil cooler that is disposed in the oil supply system and cools the oil by using cooling air generated by a cooling fan, and a controller. The controller stops the electric motor and the cooling fan when the continuation time of no-load operation has reached a predetermined value. Further, the controller predicts the return timing at which the electric motor is restarted, on the basis of a sensing history of the delivery-side pressure sensor, and predicts the delivery-side temperature of the compressor main body at the return timing.

摘要： A “bolt on” static separator is disclosed for use in conjunction with a rotating separator to handle higher liquid volumes that are not able to be effectively separated by the rotating separator alone. The static separator may be positioned upstream of the rotating separator, generally right in front of the rotating separator, i.e., immediately ahead of the inlet to the rotating separator and generally attached directly to the front end of the rotary separator. The static separator may include a significant change in flow path direction that is sufficient to cause coarse fluid separation. The output of the static separator is in communication with the input of the rotating separator. Additionally, the drain of the static separator is in communication with the drain of the rotating separator and is at the same pressure.

摘要： A method and corresponding gas processing system for cleaning deposited solid material from a fouled portion of a gas compressor whilst the gas compressor is in situ in a natural gas processing system are provided. Cleaning of a gas compressor is achieved by accumulating liquid removed from cooling gas used for cooling the gas compressor and supplying the accumulated liquid to an inlet of the gas compressor in order to remove deposited solid material from the gas compressor. The cooling gas is extracted from an intermediate stage of the gas compressor.
