Compressor section separated
Thread Content
At the compressor stage, if the cooling water pressure is greater than the process gas pressure, is it necessary to add a gas-liquid separator after a stage of cooling?
Of course a separator needs to be installed.
The common reason for adding a gas-liquid separation tank after the compressor cooler is because there is condensate after the medium is cooled. If the cooling water pressure is greater than the process pressure, it is best to have a gas-liquid separation tank behind to prevent cooling water from entering the compressor and damaging parts after the cooler leaks. (personal opinion)
It's better to pretend. It can save you a lot of trouble.
It is necessary to prevent the first level from carrying water into the second level.
It’s best to add one to avoid trouble in the future! ~
It’s best to add one to be prepared! After the heat exchanger is used for a period of time, internal leakage will occur to some extent. Once it enters the system, the problem will be serious.
It sounds good, but the separator will occupy a large area. As long as the condensation discharge is strictly monitored, it should be able to meet the operating requirements.
It is best to add a separator, but you still need to pay attention to condensation discharge. You should insist on checking during hourly inspections and before starting up to prevent water hammer accidents in the compressor.
It must be added, regardless of whether the water pressure is greater or less than the process gas pressure. Because the general process gas contains either "oil, gas" or "water gas", liquid droplets will be produced after compression. If it is not separated and brought to the next level, it will easily cause liquid hammer, which will affect the service life of gas valves, etc.!
May I ask what the relationship between the cooling water pressure and the process gas pressure is and the installation of a gas-liquid separator at the compressor outlet? A gas-liquid separator is required. If the cooling water pressure is greater than the process gas pressure, it only means that after the cooler leaks, the cooling water will leak into the system and cause liquid shock in the compressor cylinder.
； Under normal circumstances, cooling water does not leak into the gas. The cooling water pressure is greater than the process gas pressure, which means that after the cooler leaks, the cooling water will leak into the system and cause liquid shock in the compressor cylinder: victory:
For units with funds and space in the factory, it is best to install a gas-liquid separator to reduce safety hazards during operation. Our unit uses a cooling separator that separates the cooling together.
