I have a client who questions whether it is necessary to have a suction accumulator high level interlock with the reciprocating compressors on an ammonia system. He feels that if an emergency shutdown occurs and the king valve is closed he would rather the compressors continued to run and force liquid into the receiver. Once a high level is reached in the suction accumulator then the receiver will no longer feed the accumulator but the compressor/s will continue to run feeding the receiver.
It seems to me that once the high level in the suction accumulator is reached, it is important that the compressor/s stop since the compressors could ultimately begin to suck liquid brought back via the suction line to the accumulator causing potentially severe damage to the compressor/s.
Can anyone please claraify this for me??
Thanks!
