  • Process for recovery of low sodium salt from bittern
    Patent number: 6890509
    Abstract: A new process for recovery of Low Sodium Salt from bittern has been described in the present invention, the said process comprising desulphatation of bittern (by-product of salt industry), evaporation of bittern in solar pans and processing of solid mixture with water to produce a mixture of sodium and potassium chlorides and optionally preparing “free flowing” and iodized, by known techniques.
    Type: Grant
    Filed: January 31, 2002
    Date of Patent: May 10, 2005
    Assignee: Council of Scientific & Industrial Research
    Inventors: Rajinder Nath Vohra, Pushpito Kumar Ghosh, Maheshkumar Ramniklal Gandhi, Himanshu Labhshanker Joshi, Hasina Hajibhai Deriya, Rohit Harshadray Dave, Koushik Halder, Kishorkumar Manmohandas Majeethia, Sohan Lal Daga, Vadakke Puthoor Mohandas, Rahul Jasvantrai Sanghavi
  • Recovery of common salt and marine chemicals from brine
    Patent number: 6776972
    Abstract: A new process for recovery of common salt, potassium chloride, concentrated magnesium chloride with enriched bromide, and high purity magnesia from brine in an integrated manner, said process comprises preparation of calcium chloride by reaction of hydrochloric acid generated in the process with limestone, desulfatation of brine with calcium chloride, production of sodium chloride of superior quality in solar pans, solar evaporation of bittern thereby producing carnallite and end bittern, processing carnallite through established processes to produce potassium chloride, recovering end bittern containing highly concentrated magnesium chloride and enriched bromide and calcination of a part of the end bittern after solidification to produce high purity magnesia and hydrochloric acid utilizable in the process.

  • Preparation of non-hazardous brominating reagents
    Patent number: 6740253
    Abstract: The present invention relates to a non-hazardous brominating reagent from an aqueous alkaline bromine byproduct solution obtained from bromine recovery plant and containing 25 to 35% bromine dissolved in aqueous lime or sodium hydroxide containing alkali bromide and alkali bromate mixture having bromide to bromate stoichiometric ratio in the range of 5:1 to 5.1:1 or 2:1 to 2.1:1 and a pH ranging between 8-12 and also relates to a method for borminating aromatic compounds by using the above brominating agent.
