Phosphoric acid

CPC v2.1 Code: 34232

About phosphoric acid

cpc code 34232 covers the production of phosphoric acid, a critical industrial chemical with a wide range of applications. Phosphoric acid is a key input for the manufacture of fertilizers, detergents, food additives, and various other products. It plays a vital role in the global agricultural and industrial sectors, contributing to the growth and development of the broader economy.

Production process

Phosphoric acid is primarily produced through the wet-process method, which involves the reaction of phosphate rock with sulfuric acid. The phosphate rock is first crushed and then mixed with sulfuric acid, resulting in the formation of phosphoric acid and calcium sulfate. The phosphoric acid is then filtered, purified, and concentrated to the desired strength.

Production inputs

The main inputs required for the production of phosphoric acid include phosphate rock, sulfuric acid, and water. Specialized equipment such as reactors, filters, and evaporators are also necessary for the various stages of the production process. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and plant operations.

Production outputs

The primary output of cpc code 34232 is phosphoric acid, which is then used as an input for the production of 31222 Fertilizers, 34239 Other chemical products n.e.c. such as detergents, and 15540 Prepared animal feeds. Phosphoric acid is also used in the food industry as a preservative and acidulant, as well as in the production of various other chemicals and materials.
