Evaporation - Jordproxa

An evaporator is used to evaporate a volatile solvent, usually water, from a solution. Its purpose is to concentrate non-volatile solutes such as organic compounds, inorganic salts, acids or bases. Typical solutes include phosphoric acid, caustic soda, sodium chloride, sodium sulphate, gelatine, syrups, Kraft liquors and urea.

KEMWorks | Phosphoric Acid

Phosphoric acid concentration. Phosphoric acid is concentrated in an evaporator heated by low-pressure steam and operating under partial vacuum. KEMWorks offers designs for forced-circulation evaporators with carbon or alloy heat exchangers. The vacuum system is designed so that no vacuum pump or steam ejectors are required. Fluorine (FSA) Recovery

AP-42, CH 8.9: Phosphoric Acid

8.9 Phosphoric Acid 8.9.1 General1-2 Phosphoric acid (H3PO4) is produced by 2 commercial methods: wet process and thermal process. Wet process phosphoric acid is used in fertilizer production. Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals,

Eco-Tec - DPU - Chemical Recovery/Purification - Aluminium .

The DPU™ can be used to purify other acid mixtures used for the graining (lithographic sector) and etching (capacitor foil sector) of aluminum. The purified rinse water is then concentrated in a specially designed vacuum evaporator to concentrate the phosphoric acid .

concentration - Heat energy of phosphoric acid evaporation .

Looking at a system in which phosphoric acid is concentrated in an evaporator which uses a constant recycle stream with a heat exchanger in this stream to heat the acid so that water evaporates out of the acid when it re-enters the main stream, How can I find the Q needed to remove a certain amount of water from the stream in order to concentrate the acid to a specific level?
