Guide for selection of process gas compressors

In the process industries such as petrochemical industry, natural gas treatment and coal chemical industry, the process gas compressor is the “heart” equipment of the device. Faced with different media characteristics (such as hydrogen, ethylene, chlorine, etc.) and working conditions, how to choose an energy-efficient and stable process gas compressor is very important. Turbo-Tech deeply analyzes the core features of centrifugal, reciprocating and screw process gas compressors, and introduces the technical breakthrough of Turbo-Tech in the field of centrifugal process compressors.
Guide for selection of process gas compressors
1.Comparison of three mainstream process gas compressors
Centrifugal compressor (speed type)
Working principle: Kinetic energy is converted into pressure energy by high-speed rotating impeller, and gas flows continuously in the machine.
-Core features:
Large flow: single machine has large flow, which is the first choice for handling atmospheric volume.
-Oil-free: dry gas seal is adopted, and the gas does not contact with lubricating oil, which is especially suitable for industrial fields with high purity requirements.
-Compact structure: small floor space and few wearing parts, suitable for long-term continuous operation.
Application scenario: pressurization of large-scale ethylene plant, air separation plant and long-distance natural gas pipeline.
Reciprocating compressor (piston type)
Working principle: the volume is changed by the reciprocating motion of the piston in the cylinder, and the gas is compressed intermittently.
-Core features:
High pressure ratio: the single-stage pressure ratio is high, which can easily realize the ultra-high exhaust pressure of tens of MPa.
-strong adaptability: suitable for complex and changeable process gas.
Frequent maintenance: There are many wearing parts such as air valve and piston ring, and the vibration and noise are loud.
-Applicable scenarios: CNG filling station, high-pressure nitrogen filling, low flow and high pressure working conditions.
Screw compressor (positive displacement)
-Working principle: The volume between teeth is periodically reduced by the meshing rotation of the male and female rotors to compress gas.
-Core features:
Smooth operation: between centrifugal and reciprocating, no reciprocating inertia force, less vibration.
-Medium flow and medium pressure: high efficiency in the range of medium and small flow, and can adapt to certain load regulation.
-Optional oil injection: the oil injection model can cool the seal, but it needs a complicated oil separation system.
Applicable scenarios: natural gas gathering and transportation, process air, and small chemical plants.
2.Turbo-Tech centrifugal gas process compressor
As a leading enterprise in the field of centrifugal compressors in China, Turbo-Tech has launched a series of high-performance centrifugal process compressors for the special needs of process gases.
