Question: (DMTO) Olefin separation unit: The purpose of multi-stage compression in the reaction gas compressor is to save compression work, reduce the compression ratio, and lower the exhaust temperature! Note: The answer will be announced automatically in two days!
The most ideal form of compression is isothermal compression, as it requires less energy and allows for a higher compression ratio; therefore, a method of staged compression and segmented cooling is employed to achieve this goal. Multi-stage compression: Reduces the inlet temperature of the separator, saving compressor power consumption.

Reduce the temperature at the inlet of the partition to save compressor power consumption.
Reduce the temperature at the inlet of the partition to save compressor power consumption
Lower the fuse inlet temperature to save compressor power consumption.
Compressors account for a large proportion, so it is necessary to ensure that they operate properly under optimal conditions, while striving to reduce power consumption in order to achieve efficient operation with high productivity and low costs. Multi-stage compression primarily reduces the compression ratio of single-stage compression, thereby lowering equipment manufacturing costs and energy consumption.
It can save compression work, reduce the compression ratio, and lower the exhaust temperature
The purpose of using multi-stage compression is to install intercoolers between stages, so that as pressure increases, the temperature remains low enough to prevent diene polymerization or the formation of tar deposits in the compressor’s diffuser, thus avoiding disruptions to normal production.
Multi-stage compression facilitates purification and separation between various stages of the compressor, reduces the temperature at the inlet of each stage, and saves energy consumption of the compressor.
