China Screw Compressor Set for Tail Gas

SCREW COMPRESSOR SET FOR TAIL GAS
Petrochemical refinery has new ways to handle the tail gas now. According to the composition of tail gases, some plants are no longer satisfied in simply collecting the flare gas as furnace fuel, they utilize separation the chnology to treat the tail gas, recovering the H2, desorbed gas and liquid CO2. Such as 'Tail Gas Recovery and Hydrogen Generating Device', apart from H2, generation (99.99% content is H2), the separated CO2 can be pressurized and condensed to produce liquid CO2, which is warmly welcome by the market.

Flow of gas-liquid piping system:
The flammable gas comes from the upstream flows into the compressor after purified by scrubber, and then mixed with injected coolant during the compression process, and the gas-liquid mixture will be discharged flows into the separator after compression and cooling. The separated flammable gas enters into downstream piping network as well as separated coolant re-injected into compressor internal, doing the closed circulation in this way.
Process of lubricant piping system:
Lubricating oil in lubrication oil tank pressurized into the main oil pipeline by lubricant pump, passing through the filter and the cooler entering the oil distributor before divided into several ways to the corresponding lubricating points of the compressor. Then flow back to the oil tank through oil return pipe, and the closed circulation is finished.
Advantages of screw compressor set:
1. It's a wet screw compressor, safe and reliable. It's cooled by injected liquid to maintain a lower temperature in the compression chamber.
2. Compressor is acting continuously keeping the discharge pressure stable.
3. It has few wearing parts, reliable operation, long service life and low maintenance cost.
4. High automation, the operators do not need professional training for a long time, and the unit can unattended operating.
5. Low vibration, the compressor can run steadily with high speed, no foundation is realized.
6. Small size, light weight and small occupation area.
7. The effects of the discharge pressure on volumn flow is almost free with the characteristics of gas forced transmission, keeping high efficiency in wide range. In circumstances of no changes of the compressor structure, it is suitable for many working conditions.
8. Baosi water-injected screw compressor is equipped with mechanical seal, to ensure the separation of gas-liquid system and lubricant oil system, so as to avoid the substances in the gas-liquid system entering the bearing lubrication oil system. Make sure the compresor can run reliably.
9. Baosi screw compressor can be equipped with pre- and post processing system, making the operation more stable and make the compressor gas cleaner.
