ABSTRACT:
A control system for a compressor utilized in transferring natural gas from relatively low pressure wells to a relatively high pressure pipe line incorporating automatic shutdown of the compressor and automatic restart of the compressor in response to certain conditions with the compressor operating at a desired flow rate regardless of upstream fluctuations in pressure. The compressor is unloaded upon shutdown and remains unloaded for a timed duration after startup thereby reducing the required motor size, compressor wear and also eliminating manual startup for most of the usual causes of gas compressor shutdown, such as low well pressure and high discharge line pressure.
