MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202411092849 A) filed by Hpcl-Mittal Energy Limited on November 27, 2024, for A System And Method For Determining Organic Chlorine Content In Petroleum Or Petrochemical Streams.
Inventors include Dr. Hemant Tyagi; Anuj Gupta; Anurag Pathak; and Manvendra Singh Patel.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present invention generally relates to asystem and method for determining organic chlorine content in petroleum or petrochemical streams. The system comprises an injection module configured to introduce a sample, consisting of a 204 °C cut of washed naphtha or equivalent, into a gas stream; a gas supply unit configured to deliver a gas mixture of approximately 80% oxygen and 20% inert gas selected from argon, helium, or nitrogen, into the injection module; a combustion unit maintained at approximately 800 °C to convert chlorine in the sample to chloride and oxychlorides; a titration cell, comprising: an electrolyte containing 75% acetic acid in water, a silver ion solution to react with chloride ions in the sample, resulting in a measurable electrochemical reaction; and a microcoulometer configured to measure the electric current required to replace consumed silver ions in the titration cell, wherein the measured current is indicative of the organic chlorine content.
