Abstract: Organic sulfur compounds which are generally present in the crude oil undergoes various transformations while processing the crude oil in the secondary processing units such as fluid catalytic cracker, hydrocracker, delayed coker, visbreaker, etc. The sulfur present in the feed which enters into these secondary processing units are distributed into various products coming out of the units. Sulfur compounds which are present in the various product fractions are removed to meet the desired specifications before routing to the final product pool. Conventionally, sulfur present in the LPG has been removed by amine treatment followed by caustic and water wash. The present invention relates to a process for removal of sulfur and other impurities from Liquefied Petroleum Gas (LPG) comprising olefins through reactive desulfurization route. The present invention is an eco-friendly process as it minimizes or eliminates the use of caustic which is conventionally used to remove the sulfur from LPG.

Abstract: Systems and methods use ion exchange to extract lithium from a lithium-containing feed solution such as a salar brine. Lithium ions are loaded into an ion exchange resin and then eluted while recharging the resin. Sodium hydroxide or sodium bicarbonate may be used to recharge the resin but are not directly mixed with the lithium-containing feed solution. An eluate stream is produced containing lithium hydroxide or lithium bicarbonate. Lithium hydroxide can be precipitated as lithium hydroxide or in a hydrate form. Lithium bicarbonate may be converted to lithium carbonate. The system and method optionally includes processing an eluate stream to recover one or more compounds for re-use in regenerating the resin bed.
