Abstract
Phosphoric acid is one of the semi-finished products produced by PT. Petrochemical Gresik. Thus, proper calculations and data processing are needed to increase the quantity and quality of products. In Department III there are two types, namely IIIA and IIIB. The Phosphoric Acid Unit is a product of Departments IIIA and IIIB, where there are various units namely grinding unit, reaction unit I, filtration unit I, reaction unit II, hydration unit filtration II, concentration unit and fluorine recovery unit. Premixer (R-2301) is a reactor whose function is to react semi-finished phosphate rock with H3PO4 to form Ca(H2PO4)2 . So that the Premixer tool can help digester 1 to form hemyhydrate crystals. Calculation of the premixer mass balance (R-2301) obtained a total mass of 36768.1896 kg/hour. It can be concluded that the premixer digester (R-2301) is still feasible to use.
