BRINE PRIMARY PURIFICATION The saturated brine coming from Brine Saturator is treated by means of appropriate chemicals to perform primary brine purification in order to precipitate most of the raw salt contained impurities. The main impurities normally contained in...

HYDROCHLORIC ACID SYNTHESIS, STORAGE AND FILLING The present operating instructions describe the production of 33% hydrochloric acid, from chlorine and hydrogen gas produced in the membrane electrolysis plan...

INTRODUCTION: Simultaneous production of chlorine, Caustic soda solution and hydrogen from aqueous solution of alkaline chlorides by application of direct current, commonly known as the electrolysis of alkaline chlorides has been widely adopted in the chemical industry...

CAUSTIC EVAPORATION PLANT The purpose of the plant is to concentrate the 30 % caustic coming out of the electrolysers to 50% caustic lye. This concentration is achieved by three multi effect evaporators. These evaporators concentrate the 30% caustic to 36 %, 42 % and...

DESCRIPTION OF FUNCTIONING OF A CONCENTRATION PLANT WITHOUT VAPOR HEAT RECUPERATION The concentration plant consists mainly of a final concentrator (1) which is heated by molten salt used as heat transfer medium. The concentrator operates under normal atmospheric pressure....

FOOD GRADE BLEACHING EARTH PLANT Operating Instructions Dryers Check the air pressure, temperature and natural gas pressure at the furnaces. Adjust these parameters if any deviation is observed. Normally air pressure should be between 400-450 mm WC and furnace temperature...

CONTACT SULFURIC ACID PLANT INTRODUCTION: Sulfuric acid (oil of vitriol, H2SO4) is a colorless, oily liquid, dense, highly reactive, and miscible with water in all proportions. Heat is evolved when concentrated sulfuric acid is mixed with water and, as a safety precaution,...
