Mumbai: Reliance Industries Ltd (RIL) has selected ABB Lummus' path-breaking Helixchanger design for its feed product exchanger in the MEG plant at Hazira, Gujarat.
This large diameter exchanger shall be fabricated by ABB Lummus' licensee, Tema India Ltd. Helixchanger design is known for low pressure drop, low temperature approach, lower shell side fouling, robust bundle construction to handle flow induced vibrations and lower overall weight as compared to a conventional shell and tube exchanger.
Says ABB Lummus Heat Transfer (India office) director V Kaul: "The project offers unique challenges to work out a technically workable solution at substantially lower cost than the conventional design. The confidence reposed by Reliance in our technology has already enthused other Indian refiners to explore using Helixchanger in refinery and feed-effluent applications."
ABB Lummus Heat Transfer has supplied over 700 Helixchanger worldwide to oil refining, petrochemicals, fertiliser and other industries in various applications. In India, it has been installed in the Indian oil refinery at Haldia. Helixchangers are known to reduce fouling in refinery operations thus prolonging run length in refineries, which most refiners look for. They are used by gas compressor manufacturers as inter- and after-coolers due to lower pressure drops.
ABB Lummus acquired Helixchanger technology from Vuchz, Czech Republic, in 1994, which had already achieved excellent results in their own plants. ABB Lummus has an impressive list of clientele such as Exxon-Mobil, Total Fina, Fluor Daniel, ESSO, Texaco, Saudi Aramco, Indian Oil Corporation and BP Amoco.
ABB Lummus' Indian licensee has in the past exported large Helixchanger to Saudi Aramco and is expecting a repeat order for a large number of similar exchangers. A huge potential exists for Helixchangers in India and, according to sources, it is just the beginning.
