Introduction

Upendra Padmakant Saraiya is a notable inventor based in Bhavnagar, India. He has made significant contributions to the field of chemical engineering, particularly in the production of various chemical compounds. With a total of 2 patents, his work showcases innovative processes that enhance the efficiency of chemical production.

Latest Patents

Saraiya's latest patents include a groundbreaking process for the simultaneous production of potassium sulfate, ammonium sulfate, magnesium hydroxide, and/or magnesium oxide from kainite mixed salt and ammonia. This process involves treating kainite mixed salt with water to obtain solid schoenite and a schoenite end liquor. The end liquor is desulphated using recycled calcium chloride, which is then evaporated to obtain camallite crystals, from which potassium chloride is recovered. Additionally, gypsum produced during desulphatation is reacted with aqueous ammonia and carbon dioxide to produce ammonium sulfate and calcium carbonate. The calcium carbonate is calcined to obtain calcium oxide, which is then reacted with the magnesium chloride-rich liquor to produce a slurry of magnesium hydroxide. This slurry can be surface modified and calcined to produce magnesium oxide.

Another significant patent involves a new process for the recovery of common salt, potassium chloride, concentrated magnesium chloride with enriched bromide, and high purity magnesia from brine in an integrated manner. This process includes the preparation of calcium chloride by reacting hydrochloric acid generated in the process with limestone, desulfatation of brine with calcium chloride, and the production of sodium chloride of superior quality in solar pans. The solar evaporation of bittern produces carnallite and end bittern, which are processed to recover potassium chloride and high purity magnesia.
