Chlor-Alkali UnitThe chlor-alkali plant produces chlorine, caustic soda and hydrochloric acid. The plant sizing is such that all the produced chlorine is consumed within the facility. Caustic that is surplus to the facility’s requirements is sold as 32% NaOH.Salt from nearby Intrepid Potash is used as the feedstock to the chlor-alkali plant. It is purified before use in the electrolyzers where chlorine, caustic and hydrogen are produced. A portion of the chlorine and hydrogen are reacted to produce hydrochloric acid solution. The split between chlorine production and HCl production is dictated bythe De Dietrich chlorination and acidification requirements. Caustic is predominately used by De Dietrich to produce the NaBr. In addition to salt the chlor-alkali plant requires carbon dioxide, nitrogen and hydrogen peroxide for various unit operations within the plant. The consumption of these chemicals is considered in the operating cost calculation.The balance of the plant requirements such as utilities and power are supplied to the chlor-alkali plant from the common facilities.Exhaust Air TreatmentAll exhaust air streams from the plant, containing chlorine and bromine are collected and fed to the bottom of a vent scrubber. Passing the column in counter-current flow with a part of the feed brine, bromine is absorbed, and chlorine oxidizes bromide to bromine. The solution leaving the scrubber is fed to the top of the Reaction Columns. Residual bromine and chlorine in the exhaust air from vent scrubber is fed to a caustic scrubber for final scrubbing before venting to the atmosphere. SummaryDe Dietrich Process Systems GmbH (De Dietrich) successfully completed test work to extract bromine from the Paradox Project brine, which resulted in a recovery of 90%. The test work was conducted in De Dietrich’s bromine pilot plant in Germany and validates the first stage test work conducted in laboratory scale equipment. The conventional bromine extraction process has five parts:•Oxidation of the brine using chlorine gas to convert dissolved bromide ions into dissolved bromine liquid;•Heating of the brine to 60-80°C to accelerate the evaporation of the bromine, taking it from being part of the brine to being in the gas phase which can be separated easily;•Condensation of the bromine in gas phase to bromine in liquid phase;•Scrubbing of the bromine to remove trace chlorine gas; and•Scrubbing of the bromine to remove trace water.

So by rights A1 could purchase a plant from De Detriech.
