Wet G as C om pressor Train

The vapours or wet gases from the reactor are com-pressed by the Wet Gas Compressor (WGC) beforebeing transferred to the high-pressure condenser.Typically, the Wet Gas Compressor isa two-stage inter-cooled centrifugal compressor driven by an industrialsteam turbine.

MAN Diesel & Turbo supplies the Wet Gas Compres-sor, an optimized machine for specific process con-ditions and fully compliant with NACE requirements,as well as the respective steam turbine driver. Bothmachines are designed according to the specificcustomer and process requirements, fully tested andassembled in the factory.

Competenc ies

Additionally, the entire supply chain is continuouslydeveloped further for an optimum flow of materialsand reduced lead times.

In 2004, a sophisticated assembly and test centrefor large machine trains was commissioned includingoverhead cranes, cooling towers, steam supply linesand substantial electrical power supply system. Thisenables MAN Diesel & Turbo to work on several ma-chine trains with modules up to 600 tons of weight atthe same time by using an area of more than 4,500 m2.
