Agriculture: Nitric acid processing trends Nitric acid processing trendsAccording to Merchant Research & Consulting Ltd (UK) consulting agency, the current global market for adipic acid is pretty well supplied, and the demand for industrial chemicals has been steadily growing. [ClickPress, Tue Mar 27 2007] According to Merchant Research & Consulting Ltd (UK) consulting agency, the current global market for adipic acid is pretty well supplied, and the demand for industrial chemicals has been steadily growing. The global demand for industrial chemicals based on nitric acid grows by an average of 7% per year. The production of industrial chemicals based on nitric acid a€“ adipic acid, TDI, nitrobenzene a€“ is located mainly in Western Europe and USA, with a recent output expansion shift to eastern Asia. In India, the market for concentrated nitric acid has been developing at a quick pace (7% a year). Apart from the use of concentrated nitric acid by military enterprises, this product is applied in the manufacture of nitro-aromatic compounds, acrylonitrile fibre, pesticides, medicines, pigments. The highest growth of nitric acid consumption occurs in such sectors as pharmaceuticals and pesticides. The global nitric acid output tops 750-800m tons, only 15-20% of which enters the market and about 8-10% is involved in foreign trade. The remaining nitric acid is consumed by producers of nitric fertilizers, adipic acid, and other chemicals. Nitric acid is a basic chemical for the manufacture of the majority of nitrogen-containing products: up to 75-80% of nitric acid is used to obtain ammonium nitrate and calcium-ammonium nitrate, carbamide-ammonium nitrates, magnesium-ammonium nitrate, as well as various nitrogenous, phosphoric and potassium fertilizers. This market research report also features the following information: Nitric acid applications; World market for nitric acid; Development trends and modern technologies of the manufacture of chemicals based on nitric acid; etc.
