Regulation of parallel operation of reciprocating compressors

Claim 1

A METHOD FOR ELIMINATING OF STALLING OF A RECIPROCATING GAS COMPRESSOR DUE TO OVERLOAD, AND NORMALLY OPERATING TO COMPRESS EFFUENT GAS OF A PROCESS AT SUBSTANTIALLY FULL COMPRESSOR LOAD UNDER A NORMAL OPERATING COMPRESSOR INTAKE PRESSURE, SAID GAS RESULTING FROM A PROCESS IN WHICH THE EFFUENT GAS ISSUES FROM SAID PROCESS AT ABOUT SAID NORMAL OPERATING PRESSURE, SAID PROCESS INVOLVING STEPS OF TREATNG A VAPOROUS FLUID WHEEIN PRESSURE OF THE FLUID IN PROCESS IS REDUCED FROM A CHARGE PRESSURE HIGHER THAN SAID NORMAL OPERATING PRESSURE COMPRISING PASSING EFFLUENT GAS FROM SAID PROCESS AT A PRESSURE HIGHER THAN SAID NORMAL OPERATING PRESSURE TO THE INLET OF SAID COMPRESSOR, COMPRESSING THIS GAS OF HIGHER INLET PRESSURE WHEREBY SAID COMPRESSOR TENDS TO STALL DUE TO OVERLOAD, SENSING THE INCREASED PRESSURE OF SAID GAS AND REDUCING THE RATE OF FLOW OF VARIOUS FLUID TO SAID PROCESS IN RESPONSE TO THE SENSED INCREASED PRESSURE THEREBY ELIMINATING SAID TENDENCY TO STALL.
