Abstract: An adsorbent composition for reducing impurities of heat transfer fluids is provided and a process for the preparation of the same. The adsorbent composition comprises a layered double hydroxide in an amount in the range of 15 to 70 wt % of the total mass of the composition; alumina in an amount in the range of 30 to 85 wt % of the total mass of the composition; and optionally activated bauxite in an amount in the range of 15 to 50 wt % of the total mass of the composition. The adsorbent composition is economical and eco-friendly, having feed processing capacity in the range of 58 to 600 gm/gm.

Abstract: The present disclosure provides an effective and efficient process for the preparation of a dry chlorinated polyvinyl chloride (CPVC), comprising introducing chlorine gas into slurry of polyvinyl chloride in water to obtain a reaction mixture; irradiating the reaction mixture to obtain a product mixture comprising CPVC and water solution including unreacted chlorine gas and hydrogen chloride; filtering the product mixture to obtain a first mass; adding water to the first mass for extracting unreacted chlorine gas and hydrogen chloride to obtain an aqueous suspension, and filtering the aqueous suspension to obtain a second mass; passing nitrogen through the second mass to extract residual water solution to leave behind a third mass; and agitating the third mass in a high-speed mixer together with a neutralizing agent, and optionally with a stabilizer and a processing additive to obtain dry thermally stable CPVC with thermal stability in the range of 1000 seconds to 1500 seconds.

Abstract: The present disclosure relates to a process to reduce total acid number (TAN) of a heat transfer fluid. The process comprises contacting the heat transfer fluid with an adsorbent composition at a temperature in the range of 50° C. to 350° C. and a pressure in the range of 1 bar to 10 bar to obtain a treated heat transfer fluid having total acid number (TAN) in the range of 0.003 to 0.03 and pH in the range of 6 to 7.5, wherein the adsorbent composition is provided in a fixed bed and the heat transfer fluid is passed through the fixed bed comprising the adsorbent composition at a liquid hourly space velocity (LHSV) in the range of 0.5 per hour to 10 per hour.
