Argon is a colourless, odourless, non-flammable, non-reactive, inert gas. Argon is used in critical industrial processes such as the manufacturing of high quality stainless steels and production of impurity-free silicon crystals for semi-conductor manufacture. Argon is also used as an inert filler gas for light bulbs and as a dry, heavier-than-air-or-nitrogen filler for the space between glass panels in high-efficiency multi-pane windows.
Kribhco has also installed Liquid argon production unit at the site. The Plant is designed to process 7,000 Nm3/hr Feed Gas (containing 12 to 14% Argon) to produce liquid Argon with a purity of min. 99.9995 vol % minimum (5 ppm max. impurity) and a guaranteed recovery rate of 94% of the argon contained in the feed gas. This plant is based on a cryogenic Linde process consisting of equipments like cold box unit, compressors, heat exchangers, argon boil off condenser, argon recovery column, argon purification column, argon absorber, N2 reflux drum etc. including 2 nos. 100 m3 capacity liquid argon storage tanks along with tanker loading facility and cylinder filling station.
