Title:
METHOD FOR REDUCING PULSATION LEVEL IN MULTI-COMPRESSOR PLANT EMPLOYING RECIPROCATING COMPRESSORS
Document Type and Number:
Japanese Patent JP2020041540
Kind Code:
A
Abstract:
To provide a method for reducing the pulsation level in a multi-compressor plant in which each compressor of a plurality of compressors is driven by each motor.SOLUTION: The method manages to reduce the pulsation level by starting a first motor 110 of a first compressor 100 and then starting in succession each one of the other motors in a way to synchronize all motors between each other with a specified phase shift. The method comprises: assessing the number of compressors running in parallel; determining the worst pressure pulsation sum with a single compressor 100 running; determining the worst pressure pulsation sum with a plurality of compressors running in parallel; and achieving a different phase shift between the compressors 100, using a phase that is equal to 360 degrees/Nc, where Nc is the maximum number of compressors in operation.SELECTED DRAWING: Figure 13
