20100116639 | PRODUCTION OF HIGH PURITY BUTENE-1 FROM C4 OLEFINS/PARAFFINS MIXED GAS - The present invention relates to a hybrid process comprising an adsorption process and a distillation process for the separation of butene-1 from a C4 hydrocarbon mixture gas including butene-1, trans-2-butene, cis-2-butene, normal butane, isobutane, etc. The above hybrid process comprises introducing a gaseous C4 mixture into the adsorption tower loaded with adsorbents which adsorb olefins selectively to discharge C4 paraffins to the outlet of the tower, desorbing C4 olefins selectively adsorbed in the adsorption tower to produce high purity C4 olefins mixture gas in which isobutane and normal butane was removed, and separating the high C4 olefins mixture gas (a mixture of butene-1, trans-2-butene, cis-2-butene, and a trace amount of C4 paraffins) via distillation to obtain high purity butene-1 including a trace amount of isobutane in the top of the distillation tower and obtain a mixture gas including trans-2-butene, cis-2-butene and a trace amount of normal butane in the bottom of the tower. | 05-13-2010 |
20100288621 | Microwave apparatus and method of extracting essential oils, essence, and pigments with gas flow - Extraction apparatus and method for obtaining essential oils, essence, and pigments from odorous raw materials (e.g., plant materials and Chinese medicinal herbs) by microwave radiation heating have advantages of easy operation, higher extracting temperature and efficiency. The microwave chamber has a power level of 100 W to 1,500 W and its microwave radiation has a frequency at 915 MHz or 2,450 MHz. The extraction process can be performed without any preheating necessary. A condenser is operated at temperatures between −20° C. and 15° C. for cooling the gas flowing out of the extraction cartridges. Because both volatile fragrant compounds and pigments of the odorous raw materials can be extracted successfully by the top-down extraction fashion, the extracted essence is colorful. Since the extraction process by microwave heating is free from adding any organic solvent and/or any artificial chemical compound, the extraction apparatus and method are environmentally friendly. | 11-18-2010 |
20120037488 | Distiller - A distiller including an evaporator having at least one evaporation surface for evaporating liquid into vapor. At least one movable liquid applicator assembly has a wiper applicator which can move over the at least one evaporation surface, for wiping and applying a thin even film of the liquid on the at least one evaporation surface for evaporation. | 02-16-2012 |
20120205233 | METHOD AND APPARATUS FOR PURIFYING WATER - The present invention provides a method and apparatus for purifying water. The apparatus includes one or more fluid pipes for transporting a hot fluid and a heating unit capable of receiving the hot fluid from the one or more fluid pipes and water. The water is heated using the hot fluid to generate steam and a condensed fluid. The apparatus further comprises one or more steam pipes for transporting the steam and a fluid circulation pipe connected to the heating unit and the at least one fluid pipe. The fluid circulation pipe receives the condensed fluid from the heating unit. At least a portion of each steam pipe is arranged in a heat-exchanging relationship with the fluid circulation pipe for condensing the steam passing through each steam pipe using the condensed fluid to obtain purified water. | 08-16-2012 |
20120228116 | Vacuum Evaporator / Distillation System - An evaporator or distillation apparatus includes an inlet supply line for supplying an influent liquid, a heater configured to heat the influent liquid supplied by the inlet supply line, and a plurality of cells. Each cell includes an outer surface defining an interior chamber, an inlet, a vapor outlet, a concentrate outlet, and an inner conduit in fluid communication with the inlet. At least a portion of the inner conduit is positioned within the interior chamber. The vapor outlets of the plurality of cells are connected to each other in a parallel configuration and the inlet supply line is connected to the inlet of each cell. | 09-13-2012 |
20130001061 | RECOVERY OF BUTANOL FROM A MIXTURE OF BUTANOL, WATER, AND AN ORGANIC EXTRACTANT - A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. An overhead stream from a first distillation column is condensed to recover a mixed condensate. An entrainer is added to at least one appropriate process stream or vessel such that the mixed condensate comprises sufficient entrainer to provide phase separation of the organic and the aqueous phases to provide for recovery of the butanol. | 01-03-2013 |
20130081935 | DISTILLATION METHOD FOR THE PURIFICATION OF SEVOFLURANE AND THE MAINTENANCE OF CERTAIN EQUIPMENT THAT MAY BE USED IN THE DISTILLATION PROCESS - Processes for preparing commercial quantities of a stable, pharmaceutically acceptable sevoflurane substantially free of impurities are claimed.
