Complex Liquid Fertilizer Manufacturing Process

The Asia Pacific Center for Trade and Technology, on behalf of an Indian company, is offering a technology for the manufacture of complex liquid fertilizer.

The technology involves a chemical reaction wherein potassium nitrate is ammoniated at 25-30°C in the presence of ammonia and ammonium chloride. The ammoniated potash is neutralized using phosphoric acid at 120°C. The white viscous liquid mass obtained is cooled down to room temperature and transferred to storage tank

The product is claimed to be 100 percent water soluble, with pH of 4 to 6, and N:P:K ratio of 1:2:1. It can be used with drip irrigation or made into a foliar spray.

It is claimed that crop yield increased by 30 percent with the application of said fertilizer. The technology offers cleaner production process since the emission of ammonia can be controlled by absorbing it in phosphoric acid, with ammonium phosphate as a by-product.

Production capacity is 30,000 tons per year. The project cost is estimated at USD 7 million.

The technology has been patented.

Preferred forms of cooperation are patent sale, know-how, consultancy, technical assistance and training.
