17.06.2003 - Larsen & Toubro, India, has granted MAN Turbomaschinen AG, Oberhausen/Germany (MAN TURBO) the order to supply the turbomachinery train – consisting of air compressor, expander, steam turbine and generator – for one of the largest planned PTA plants in the world.

After being put into operation at the beginning of 2005 the plant in Panipat/India, which is operated by the Indian Oil Corporation Ltd./ India, will produce almost 600,000 tons of terephthalic acid per year. Terephthalic acid is an intermediate product in the petrochemical industry which is used to manufacture plastics and coatings as well as in the fibre industry. The process user is Dupont, Great Britain. MAN TURBO, one of the leading machine manufacturers for PTA plants, already built a plant for similar process conditions in Taiwan in the mid-1990s.

The air compressor used in this machine train is the largest gear compressor which MAN TURBO will then be able to add to its reference list. The same applies for the high-temperature expander.
All machines are calculated, designed and manufactured by MAN TURBO and tested on the company’s large machine test stand before being delivered in summer 2004.
