Is a buffer tank needed in front of a reciprocating compressor?
Thread Content
A new reciprocating compressor has been installed for pressurization; the gas comes from a liquid nitrogen tank located 500 meters away. Is it necessary to add an additional buffer tank in front of the compressor? The compressor is small, with a capacity of about 50 cubic feet per hour
It seems that the airflow coming directly from the storage tank into the compressor is stable, so there is no need for an additional buffer tank. I’m not sure if this way of thinking is correct; I hope someone experienced can give me some advice
Just increase the diameter of the pipe at the compressor inlet; the flow rate is quite low! ! Adding a buffer tank doesn’t offer much benefit!
Ultra-long pipes can also be used as buffers, but it’s best to add one. Installing a buffer tank allows for monitoring of changes in the compressor inlet pressure, which can extend the lead time; otherwise, this time will be reduced, leaving no time to respond in an emergency.
If the gas is liquid ammonia, it is recommended to add a gas-liquid separator in advance to avoid liquid slugging. Buffers can be added, and pipes are recommended to be thickened.
A buffer tank is added so that fluctuations in the compressor do not have a significant impact on subsequent gas usage
