Patent number: 9440947Abstract: Recovering a polar hydrocarbon (HC) selective solvent substantially free of hydrocarbons (HCs) and other impurities from a lean solvent stream containing the selective solvent, measurable amounts of heavy aromatic HCs, and polymeric materials that are generated in an extractive distillation (ED) or liquid-liquid extraction (LLE) process. At least a portion of the lean solvent stream is contact in a solvent clean-up zone with a slip stream from the HC feed stream of the ED or LLE process or an external stream. The HC feed stream, such as pyrolysis gasoline or reformate, contains significant amounts of benzene and at least 50% polar (aromatic) HCs and serves as a displacement agent to remove the heavy HCs and polymeric material from the lean solvent stream. A magnetic filter can be used to remove the paramagnetic contaminants from the lean solvent.Type: GrantFiled: December 6, 2012Date of Patent: September 13, 2016Assignees: AMT International, Inc., CPC Corporation, TaiwanInventors: Fu-Ming Lee, Tzong-Bin Lin, Kuang-Yeu Wu, Jyh-Haur Hwang, Jeffrey Tsung-Min Chiu, Jeng-Cheng Lee, Yu-Ming Wu, Han-Tjen Jan

Patent number: 8720650Abstract: A hub assembly for a wheelchair has a hub device and a switch device. The hub device has a hub shell, an axle, a ring and a ratchet. The ratchet has a cylinder section. The cylinder section has a recess formed in an outer surface of the cylinder section. The switch device has a pin and a wire. The pin is capable of being selectively inserted into the recess. The wire is securely connected with the pin. Because the pin is inserted into the recess and the ratchet engages the ring, the hub shell along with a wheel cannot be moved unintentionally backward on a ramp.Type: GrantFiled: July 30, 2012Date of Patent: May 13, 2014Inventor: Yu-Ming Wu

Patent number: 7879225Abstract: An energy efficient, high throughput process for aromatics recovery can be readily implemented by revamping existing sulfolane solvent extraction facilities, or constructing new ones, so as to incorporate unique process operations involving liquid-liquid extraction and extractive distillation. Current industrial sulfolane solvent based liquid-liquid extraction processes employ a liquid-liquid extraction column, an extractive stripping column, a solvent recovery column, a raffinate wash column, and a solvent regenerator. The improved process for aromatic hydrocarbon recovery from a mixture of aromatic and non-aromatic hydrocarbons requires transformation of the extractive stripping column into a modified extractive distillation column. The revamping incorporates the unique advantages of liquid-liquid extraction and extractive distillation into one process to significantly reduce energy consumption and increase process throughput.Type: GrantFiled: July 8, 2008Date of Patent: February 1, 2011Assignees: CPC Corporation Taiwan, AMT International, IncInventors: Fu-Ming Lee, Kuang-Yeu Wu, Tsung-Min Chiu, Zong-Ying Chen, Jyh-Haur Hwang, Tzong-Bin Lin, Hung-Chung Shen, Tung-Hsiung Kuo, Yu-Ming Wu

Patent number: 7871514Abstract: Extractive distillation processes whereby water-soluble extractive distillation (ED) solvents are regenerated and recovered employ improved operations of the extractive distillation column (EDC) so that polar hydrocarbons are recovered and purified from mixtures containing polar and less polar hydrocarbons and measurable amounts of hydrocarbons that are heavier than intended feedstock and/or polymers that are generated in the ED process. The improved process can effectively remove and recover the heavy hydrocarbons and/or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein.Type: GrantFiled: December 12, 2008Date of Patent: January 18, 2011Assignees: CPC Corporation, Taiwan, AMT International Inc.Inventors: Fu-Ming Lee, Tzong-Bin Lin, Jyh-Haur Hwang, Hung-Chung Shen, Kuang-Yeu Wu, Tsung-Min Chiu, Zong-Ying Chen, Tung-Hsiung Kuo, Yu-Ming Wu

Patent number: 7666299Abstract: A process for recovering polar hydrocarbons from non-polar hydrocarbons, such as aromatics from non-aromatics, naphthenes from paraffins and isoparaffins, or olefins from paraffins and isoparaffins, in feed mixtures containing at least a measurable amount of heavier hydrocarbons. This improved extractive distillation (ED) process recovers aromatic hydrocarbons including benzene, toluene, and xylenes from the C6-C8 petroleum streams containing a measurable amount of C9+ hydrocarbons. The ED process also recovers benzene and toluene from the C6-C7 petroleum streams containing a measurable amount of C8+ hydrocarbons. The ED solvent utilized to recover and purify the aromatic hydrocarbons from the petroleum stream with a heavier than intended feedstock of hydrocarbons is also regenerated and recovered.Type: GrantFiled: August 10, 2007Date of Patent: February 23, 2010Assignees: AMT International, Inc., CPC CorporationInventors: Kuang-Yeu Wu, Tsung-Min Chiu, Tzong-Bin Lin, Hung-Chung Shen, Yu-Ming Wu, Tung-Hsiung Kuo
