MAN Diesel & Turbo is a supplier of compressor trains for air separation units (ASUs), as shown in the infographic. The demand for air separation solutions is constantly growing – together with the demand for industrial gases, in processes such as gas-to-liquids (GtL) or coal-tochemicals.
The AIRMAX machinery train concept – an industry- leading solution from MAN Diesel & Turbo – contains an axial/radial main air compressor with highly developed MAX1 blading, featuring higher rotating speeds and higher blade-tip speeds. AIRMAX can handle flows up to 53 million cubic feet/hr (1.5 million m3/hr) or higher, enabling a single plant to produce up to 8,000 metric tons of oxygen per day.
In one of the latest ASU projects, Air Liquide will use MAN AIRMAX technology to build the world’s largest air separation unit in Secunda, South Africa. With a production capacity of 5,000 tonnes of oxygen per day, the ultra-modern facility pushes technical boundaries. The AIRMAX train, being the heart of the plant, comprises a main air compressor of the largest MAX1 type (AR140), and an RG 71-4 booster compressor. In this project, a 65 MW electric motor drives the main air compressor. This differs from the typical train concept, shown in the infographic, where both compressors are driven by a steam turbine.
Once again, this is a proof of the flexible, highly efficient air separation solutions that MAN Diesel & Turbo provides.
