A centrifugal compressor refers to a turbine compressor with an exhaust pressure higher than 0.015MPa and where the gas mainly flows radially. It is also known as a radial flow compressor. Those with an exhaust pressure lower than 0.2MPa are generally also called centrifugal blowers. It is widely used in various process flows to convey air, various process gases or mixed gases and increase their pressure. In industry, they are often named according to their uses or types of gases, such as blast furnace blowers and ammonia centrifugal compressors, etc. Centrifugal compressors play a significant role in various sectors of the national economy, especially in industries such as metallurgy, petrochemicals, natural gas transportation, refrigeration, and power, where they are widely applied.

In recent years, against the backdrop of economic globalization and fierce competition, the foreign centrifugal compressor manufacturing industry has also undergone continuous mergers and acquisitions and reorganizations.

In this article, let's first take a look at a well-known European manufacturer of centrifugal compressors:

Atlas Copco

Atlas Copco of Sweden was founded in 1873 and is currently one of the world's largest multinational industrial groups, with its headquarters located in Sweden.

Its Compressor technology department has a total of 10 branch factories, mainly producing reciprocating, screw and centrifugal compressors suitable for air and other industrial gases, as well as their matching dryers, filters, coolers, energy recovery systems and control systems, etc. Among them, the AIRPOWER branch factory in Belgium is the world's largest manufacturer of screw compressors, with an annual output of tens of thousands of units. The ENERGAS branch factory in Germany specializes in manufacturing special process gas compressors. The COMPTEC and ROTOFLOT branch factories in California, USA, produce centrifugal air compressors, process compressors and expanders.

Mann Turbomag Group of Germany

In 2001, the German MAN Group reorganized GHHBOSIG and Sulzer to form the MANTURBO company. MANTURB0, a subsidiary of the German ManAG Group, one of the Fortune Global 500 companies, is the world's largest manufacturer of turbomachiners and compressor equipment.

Sulzer

Sulzer, a world-renowned multinational industrial group company, was founded in 1834 and has a history of over a hundred years. Currently, it has permanent representatives in 150 countries, with approximately 320,000 employees worldwide and an annual sales volume of 6 billion Swiss francs. Sulzer mainly engages in textile machinery, medical technology, hydraulic machinery, thermal turbine machinery, process flow and complete sets of equipment, reciprocating compressors, centrifuges, industrial pumps, etc.

The flow rate range of the produced horizontal agent separation centrifugal compressors is 4,000 to 220,000 m ³ /h, with a maximum outlet pressure of 70 B. They are mainly applied in oxygen compression, refrigeration units, and the petrochemical and chemical industries for transporting various medium gases (ar). The flow rate range of the vertical agent separation barrel centrifugal compressors (6 types of units) is 3,000 to 45,000 m ³ /h. The outlet pressure is 700bar. It is mainly applied in high-pressure oxygen, synthetic ammonia gas compression, hydrocarbon gas compression, oil refinery gas compression, gas transportation, natural gas use, etc

The Turbine machinery Division of Siemens, Germany

SIEMENS acquired DEMAG DELEVAL Turbine Company in 2001, forming the Siemens Turbine Machinery Division. The company consists of three major parts, namely Mannesman-de Mag in Duisburg, Germany, Drava in Trenburg, the United States and Drava-Stoker in the Netherlands. There are a total of 2,650 employees in these places. This company has a history of 150 years and possesses various patented technologies of the original three companies. It is capable of manufacturing various types of centrifugal compressors and steam turbines. Its main products include: centrifugal compressors, multi-shaft gear-speed-increasing centrifugal compressors, axial flow compressors, slurry flow compressors, gas expanders, industrial steam turbines, etc.

Demag Company, Germany

The compressors produced by Demag of Germany include :AX series centrifugal compressors, AR series mixed-flow compressors, RR series high-flow centrifugal compressors, MH series horizontal split core compressors, MV series vertical split core compressors, H(VK) series multi-shaft (high-pressure) gear-speed-increasing centrifugal compressors, PRT series process gas compressors, and SEI/SEE Series single-stage centrifugal compressors.

2. Delaware Corporation of the United States

Delaware Corporation of the United States was founded in 1901 and has a long history of manufacturing steam turbines. Its industrial turbines are mainly used on military warships. It began to manufacture fuel gas compressors in the 1950s. In the United States, Kellogg Company developed a 300,000-ton/year ammonia synthesis process. In the 1960s and 1970s, Delaware Company supplied a large quantity of four major units, namely air compressors, raw gas compressors, synthesis gas compressors and chillers, for the 300,000-ton/year ammonia synthesis production. The centrifugal compressors and steam turbines produced by Drava are currently in operation in 700 units of 90 large-scale ammonia synthesis plants around the world. Among the 13 sets of 300,000 tons per year large-scale fertilizer plants introduced to China in the mid-1970s, 8 sets of the four major units were produced by the Drava factory.
