【Q&A Question 224】Why is a liquid separation tank installed before the inlet of a reciprocating compressor on 2018.08.18? To increase the compressor’s displacement, compressors are generally designed with relatively small clearance volumes; especially in the design of cylinders at higher pressure levels, the clearances are kept very small. When a large amount of liquid is carried in the gas, the piston in the cylinder compresses this liquid; since liquids are incompressible, if the volume of liquid introduced exceeds the available space in the cylinder and it cannot be discharged in time, cylinder collision occurs, damaging the components of the compressor and leading to equipment failures. Additionally, the increased density due to the presence of liquid in the gas can cause the motor to overload during compression, and prolonged operation under such conditions can damage the motor as well. Therefore, a liquid separation tank must be installed in front of the cylinder inlet at each stage of the compressor. .

1 Stable pressure 2 Prevent liquid carryover
It provides a stable airflow to the compressor, allowing the gas condensate in the inlet pipeline to be separated in the inlet separator tank, thereby preventing liquid from entering the compressor cylinders.
It is mainly to prevent the liquid phase from entering the compressor and affecting its efficiency
It provides a stable airflow to the compressor, allowing the gas condensate in the inlet pipeline to be separated in the inlet separator tank, thereby preventing liquid from entering the compressor cylinders.
To increase the compressor’s displacement, compressors are generally designed with relatively small clearance volumes; this is especially true in the design of cylinders at higher pressure levels, where the clearances are made very small. When a large amount of liquid is carried in the gas, the piston in the cylinder will compress the liquid; however, liquids are incompressible. When the volume of liquid introduced exceeds the clearance volume of the cylinder and cannot be discharged in time, cylinder collision occurs, damaging the components of the compressor and leading to equipment failures ； At the same time, as the gas contains liquid, its density increases; this can cause the motor to overload during compression. Prolonged operation under such conditions can damage the motor. Therefore, a liquid separation tank must be installed before the inlet of each cylinder stage in the compressor.
It mainly serves to further separate the small amount of liquid droplets present in the gas, ensuring that the gas entering the compressor is free of liquid and allowing the compressor to operate properly

When a large amount of liquid is carried in the gas, the piston in the cylinder compresses this liquid; since liquids are incompressible, if the volume of liquid introduced exceeds the free volume available in the cylinder and it cannot be discharged in time, cylinder collision occurs, damaging the components of the compressor and leading to equipment failures. Additionally, the increased density due to the presence of liquid in the gas can cause the motor to overload during compression, resulting in damage over time.
