Abstract

Abstract

Sodium carbonate and Kalium Chlorde are two major Chemical compound in industry

such is glass, pulp, soap and paper industry. Sodium carbonate and kalium chloride can be

produces simultaneously from coconut shell  fiber as by solvay type process. The ash coconut shell fiber contain larger portion of Kalium carbonate (35-45%-b Dikaliumoxide). The Material used in the research were kalium carbonate , kalium bicarbonate

sadium chloride, carbon dioxide , kalium chloride, sodium carbonate ,sodium bicarbonate

and water. The research parameter were the solubility of the salts kalium carbonate

sodium chloride, sodium carbonate ,kalium chloride, sodium bicarbonate and kalium

bicarbonate. For the solid liquid phase equilibrium data the observation for K+-Nα+-

CI- CO3 - -H2O system was conducted. 30-40C and for K+-Nα+- CI- HCO3 - -H2O

system the observasion was conducted at 55-65C They also help to identify the

separation boundaries , the condition of operation ,the lise of solids that are  most likely to

precipitate and many more. Information, the generated SLE-phase ,diagrams such as

phase boundary data and saturation point data may be used to solve grapichally the mass

balance equations is related to the operational pathson the phase diagrams,  the

temperature dependent phase boundaries and the solubility index it is possible to

simultaneously design.analize and simulate both continous flow sheets wich

crystallization operation and sequences of batch.operations. The Simultaneous graphical

not only provides a visualization of the process operation, but also,provides very goods

initial estimates for future simulations with rigorous model.Jancke diagram .from Na + K t –

CI- HCO3 - -H2O system at 50 C has the crystallization field.while the widest

crystallization field for the Na + K t – CI- HCO3 - -H2O system was obtained from process at 40⁰C
