　　In the core links of modern industries such as petrochemical industry, coal chemical industry and natural gas treatment, the process gas compressor plays a "heart" role-it drives complex chemical reactions and realizes gas transportation and recovery by converting mechanical energy into gas pressure energy. So, what are the mainstream types of process gas compressors? Next, Turbo-Tech compressor introduces the main types and characteristics of process gas compressors in detail.

　　Introduction of mainstream types of process gas compressors

　　I. Positive displacement compressor

　　Positive displacement compressor can improve the pressure by reducing the volume of gas, which is characterized by strong pulsation of air flow, but it can provide high pressure ratio.

　　1. Reciprocating compressor

　　Reciprocating compressor is the "elder" in this field, which drives the piston to reciprocate in the cylinder through crank-connecting rod mechanism to realize gas compression.

　　Its core advantage lies in its extremely wide pressure range, which is especially suitable for gases with small flow and high pressure ratio. However, due to the reciprocating inertia force, its displacement is limited, and because there are many vulnerable parts such as air valves and piston rings, the maintenance cost is high, so it is often not economical under large flow conditions.

　　2. Screw compressor

　　Twin-screw compressor works by a pair of meshing female and male rotors rotating to produce volume change. It has a strong momentum in the field of process gas in recent years and belongs to rotary positive displacement compressor.

　　Its structure is compact, its operation is stable, and its vibration and noise are much lower than that of piston machine. However, the machining accuracy of rotor profile is extremely high, and the rotor coating is easy to wear when dealing with media rich in dust or easy to polymerize, which requires certain gas cleanliness.

　　Ⅱ.the centrifugal compressor

　　The gas is thrown to the edge under the centrifugal force of the high-speed rotating impeller to realize accelerated pressurization. It is the first choice under the condition of large flow rate, and has obvious advantages such as long operation period, no friction loss parts, small volume, continuous gas supply and no pulsation.

　　Taking Turbo-Tech centrifugal process compressor as an example, the large-scale multi-shaft centrifugal compressor successfully developed by Turbo-Tech has been applied to energy projects such as raw gas recovery and LNG (liquefied natural gas) industrial chain. This kind of centrifugal compressor not only breaks the monopoly of foreign countries in the field of high-end process gas, but also becomes the core driving force of large-scale modern industrial devices with large flow, continuous gas supply capacity and high operating efficiency.

　　To sum up, the introduction of mainstream types of process gas compressors is here. Turbo-Tech has been committed to providing long-term and low-cost gas compression solutions for enterprises for many years, helping industrial production to develop in an energy-efficient and green way.
