Enhancement of Chlorine production capacity from 140 TPD to 170 TPD by the first quarter of 2019
The project to enhance and increase chlorine production relies mainly on the installation of a third electrolyzer alongside the existing two-electrolyzer system with minor modifications in upstream and downstream equipment/piping in the existing plant to cater to the increased production capacity. The electrolyzer is designed and supplied by M/s Ineos Chlor, UK and is capable of producing 60 TPD of chlorine.
The BICHLOR electrolyzer is a bipolar electrolyzer that makes use of a modular design with two packs capable of accepting 60 elements in each pack. Present expansion requires elements in one pack with 60 elements that will produce an additional 30 mt/day of chlorine.
Below is a brief process description of the electrolyzer system for chlorine production.
A Chlor-Alkali membrane electrolyzer consists of an anode in an anolyte compartment, separated by a cation exchange membrane from a cathode in a catholyte compartment.
Ultra pure brine and caustic are fed to the electrolyzer under flow control in ratio to the electrolyzer current. Chloride ions are oxidized on the anode to produce chlorine gas. The unreacted chloride ions leave the compartment as depleted brine. Sodium ions and water pass through the membrane as a flow of electric current into the cathode compartment. The water is reduced at the cathode to form hydrogen gas and hydroxyl ions, the latter leaving the compartment as sodium hydroxide.
Product gases also exit the electrolyzer via the flexible hoses. A schematic view of the electrolyzer is shown below:
The chlorine gas generated in the electrolyzers will be wet and hot at a temperature of about 85°C, and they will also contain some NaCl particles as well. Chlorine is filtered and cooled prior to producing chlorine products such as hydrochloric acid and sodium hypochlorite. A part of the chlorine gas is dried and cooled in the chlorine treatment section to produce liquid chlorine.
To produce hydrochloric acid, hydrogen and chlorine gases generated in the electrolyzers are burned together in an HCl Synthesis Reactor to produce HydrogenChloride gas. This gas is absorbed in de-mineralized water in absorption blocks inside the reactor to produce hydrochloric acid.
