K.S. Gupta, Presiding Member—Complaint was filed by Indu Nissan Oxo Chemical Industries Ltd.-complainant, inter alia, alleging that it has a plant manufacturing oxo-alcohols at Bajuwa near Vadodara. Plant can manufacture four different oxo-alcohols – any one at a time – depending upon the raw material used. For the last about 10 years the plant has been manufacturing only two Oxo-alcohols – Iso-Octanol and Iso-Decanol. Oxo-alcohols are manufactured in “Runs”, a run being the total period for which a particular Oxo-alcohol is manufactured. Major inputs thereof are – 1. Oxo synthesis gas; 2. Hydrogen gas and 3. Olefin. Olefin is the generic name of the raw material which is imported. Two Olefins namely Heptene and Nonene are used to manufacture Iso-octanol and Iso-decanol respectively. The process comprises of two main reactions, i.e., oxonation and hydrogenation. The by products produced during the reactions are separated from alcohol by distallation. The distilled alcohol so produced has traces of aldehyde which are removed by hydrogenation in the finishing section. Distilled alcohol separated in distillation is stored in distilled alcohol storage tanks T501 A, B, C or D. Dis
