LIQUID DE-ENTRAINMENT IN HEAT EXCHANGE EQUIPMENT
20210178284 · 2021-06-17 ·

A kettle reboiler includes a shell, a liquid reservoir defined within the shell to contain a first process fluid, and a tube bundle positioned within the liquid reservoir and at least partially submergible in the first process fluid, the tube bundle being configured to circulate a second process fluid that causes the first process fluid to boil and discharge a vapor-liquid mixture. A liquid-vapor separation assembly is positioned in the shell and includes a separation deck, and a plurality of separation devices mounted to the separation deck, each separation device being operable to de-entrain liquid from the vapor-liquid mixture and discharge a vapor. A vapor outlet nozzle is coupled to the shell to receive the vapor discharged from the plurality of separation devices.

VAPOR TRAP
20210129043 · 2021-05-06 ·

A method of capturing a vaporized component or components, and apparatus for same is provided. The method involves vaporization of desired components, and capture of the vaporized components in a material using a vapor trap device. Once captured, the material with the component stored therein may be used for any number of purposes including ingestion, topical administration, and/or aromatization.

A METHOD FOR RECOVERY OF ETHYLENE OXIDE
20210163434 · 2021-06-03 ·

Ethylene oxide purification by quenching and washing ethylene oxide reactor effluent prior to passing the gaseous ethylene oxide-containing stream to an ethylene oxide absorber to form a dilute aqueous ethylene oxide and carbon dioxide solution and thereafter stripping that solution in an EO stripper to produce a gaseous ethylene oxide and carbon dioxide-containing overhead vapor which is then passed to a reabsorber wherein the ethylene oxide and part of the carbon dioxide vapors are absorbed to form an aqueous reabsorbate solution from which carbon dioxide is removed to produce an ethylene oxide-containing solution is improved by passing an impurities-containing liquid bleed stream obtained from the quench wash to a second, small quench bleed stripper where steam and carbon dioxide are added and gaseous overhead from that quench bleed stripper is passed to the reabsorber for recovery of the EO and removal of formaldehyde and other impurities.

Vacuum distillation apparatus and methods
11027215 · 2021-06-08 ·

Vacuum distillation apparatus and methods are provided. In an embodiment, an apparatus is provided that includes an evaporation chamber having a bottom flow rate control (FRC) surface that is curved to provide multiple flow rates to a solution as it flows across the bottom surface. The apparatus also includes a wiper that is curved to match the curve of the bottom FRC surface and wipes the bottom FRC surface to distribute the solution. A heater heats the bottom FRC surface to evaporate one or more components from the moving solution.
