Abstract
In certain compression stations where twin-screw compressors assemblies are installed, certain operational problems have been observed when starting the assembly again after it was shut down. The downtime can vary from several minutes to a few days, depending on the shutdown causes. The gases accumulated in the compressor suction pipe can cause the inlet gas pressure to be above the typical pressure values ranging from atmospheric pressure (1 bar) to 1.5 bar. The compressor is automatically shut down via the sequences implemented in the automation control system if the pressure at the inlet of the compression unit exceeds 1.5 bar, this value being the maximum suction pressure that the compressor unit is designed to withstand. The solution introduces a potentiometer for providing feedback on the suction valve opening angle and thus optimizing the valve control to prevent the occurrence of higher pressures which may lead to failed start-ups or emergency shutdowns.
