19.05.2003 - In August 2002, MAN Turbo received an order for the expansion of an ethylene plant. Three compressor trains, each driven by a steam turbine, are to be used. All machines are equipped with reserve rotors and have been subjected to mechanical testing on the test stand. Oil supply lines, the gas panel, condensers and the measurement and control system are also included in the scope of the order. The installation is required to increase the capacity of an existing plant in Hungary by 250,000 tonnes per year.

Ethylene is obtained from crude gas in petrochemical processes and forms the basis for many products in the plastics industry.
Ethylene plants are made up of the primary cycle and a second refrigeration cycle. The raw materials are cracked in the pipe furnace of the olefin plant and broken down into the main product and other basic materials during the subsequent distillation processes. Ethylene is extracted in four stages:
Cracking and quenching, Separation, Compression and scrubbing
Separation at low temperature.
MAN Turbo manufactures and supplies the prime movers and working machines for all process stages. References for 134 casings are available to date in this regard.

Expansion of the ethylene plant, erected in 1975, will increase its capacity from 360,000 to 610,000 tonnes per year. This investment ensures that the end customer will continue to occupy a leading position in the domestic polythene and polypropylene market.
