The manufacture of extraction phosphoric acid

Course work on the discipline "Construction materials in the technology of inorganic substances" on the topic “The manufacture of extraction phosphoric acid" The physicochemical bases of extraction phosphoric acid production was reviewed, technological flow diagram of the production process was presented. The choice of construction materials and technological equipment was justified. EXTRACTION METHOD, EXTRACTOR, PULP, PHOSPHOGYPSUM, EXTRACTION PHOSPHORIC ACID. Extractor is a reinforced-concrete rectangular device with a flat bottom. The mixers of the extractor are made of alloy steel 06ХН28МДТ. Alloy steel 08Х22Н6T should be used for the production of vacuum evaporator. In the vacuum filter, alloy steel 06ХН28МДT, 08Х21Н6M2T or 10Х17Н13M2T are used. Vacuum receiver is made of alloy steel 08Х22Н6T or 10Х17Н13M2T. Filtrate tank is made of alloy steel 08Х22Н6T. The pump is made of alloy steel Х23Н28M3Д3TЛ.
