Webthe solvation shell of xylan in THF–water is dependent on the temperature-phase behaviour. At tempera-tures between 333 K and 418 K, THF and water become immiscible, and THF is evacuated from the sol-vation shell of xylan, while above and below this temperature range, THF and water are both present in the polysaccharide’s solvation shell.
WebThe THF refining section consists of a series of four packed towers designed with a low-pressure (LP) steam reboiler, direct-injection LLP steam and a condenser at subcooled temperatures. The purpose of the recovery unit is to purify crude oil from 35 wt% to 99.95 wt%. Crude THF is generated as a byproduct from the polyester reaction.
