141	Synthesis Gas Separation and Reforming Process	US14031182	2013-09-19	US20140086818A1	2014-03-27	Richard Peter Glynn Jewell; Melissa Gaucher; Louis Denomme
A method of obtaining purified hydrogen and purified carbon monoxide from crude synthesis gas. A first crude synthesis gas stream is passed through a first separation zone to separate a hydrogen stream from a stream comprising carbon monoxide and methane. The carbon monoxide and methane are subjected to thermal reforming to produce a second crude synthesis gas, which is passed through a second separation zone to separate carbon monoxide from the second crude synthesis gas stream.
142	SYSTEM FOR RECOVERING HIGH-PURITY CO2 FROM GASIFICATION GAS CONTAINING CO, CO2, COS AND H2S	US14019951	2013-09-06	US20140010747A1	2014-01-09	Fumiaki Sato; Shinji Ogino; Motonari Aihara; Yudai Kato; Kazuo Ishida; Seiji Kakesako
A method and system for recovering CO2 from gasification gas, prevents the recovered CO2 from being contaminated with COS, without repeating cooling and heating operations and without increasing the steam consumption. Gasification gas being produced in a gasifier 10 and containing CO, CO2, COS and H2S is subjected to dust removal in a scrubber 20. Then, a part of the gas is subjected to a CO shift reaction, in which CO is converted into CO2, in a CO shift reactor 30. Another part of the gasification gas is not subjected to the CO shift reaction by means of a bypass 34, and is mixed with the gas after the CO shift reaction. Thereby, the temperature of the mixture gas is set at 180° C. to 300° C., and COS in the mixture gas is converted into H2S in a COS converter 40.
143	Method and device for the treatment of product gas produced by pressure gasification of solid fuels	US12601460	2008-05-23	US08500866B2	2013-08-06	Gerhard Schmitt
Upon cooling to 15 to 45° C., a process for the treatment of raw product gas generated by pressure gasification of solid fuels comprises the removal of HCN and NH3 in a preliminary stage, of H2S and COS and possibly other sulfur-containing compounds in a first stage and of CO2 in a second stage by physisorption with cold oxygenate, and the pure product gas is supplied to the direct reduction of iron ore as reduction gas and/or as fuel gas. An improvement of the process consists in that recycle gas loaded with CO2 and steam, which is branched off from the circuit of the recycle gas of the direct reduction of iron ore, is admixed to the desulfurized product gas upon removal of the steam contained therein.

145	METHOD AND APPARATUS FOR TREATING A SYNGAS	US13369018	2012-02-08	US20120193215A1	2012-08-02	Alice Fourcault; Jean-Paul Robert-Arnouil; Erika Edme
Treating a synthesis gas includes generating a plasma jet from a non-transferred arc torch having a main axis, the jet having a propagation axis substantially collinear with the torch main axis. The plasma torch is mounted on a feed enclosure. The syngas is received at an inlet port of the feed enclosure, downstream from the plasma torch and feeding the syngas so the flow encounters the plasma jet to mix the syngas and plasma jet in a distribution chamber. The mixture is propagated in a reactor downstream from the feed enclosure to convert the syngas into an outlet gas. The reactor is in communication in its upstream portion with the feed enclosure through a flared segment, and has a longitudinal axis that is substantially collinear with the propagation axis of the plasma jet. The outlet gas is extracted via an outlet port and particles are captured by a submerged conveyor.
146	Method of treating a gaseous mixture comprising hydrogen, carbon dioxide and hydrogen sulphide	US12835063	2010-07-13	US08226912B2	2012-07-24	Jeffrey William Kloosterman; Kevin Boyle Fogash; Andrew David Wright
A gaseous mixture, comprising CO2, H2, H2S and optionally CO, is separated into an H2 or H2 and CO product stream (H2/CO product stream), and a CO2 enriched stream containing at least one combustible component selected from H2S, H2, CO and any additional combustible components present in the gaseous mixture. A support fuel stream, comprising one or more combustible components, is combusted to form a stable flame, and the CO2 enriched stream and flame are contacted in the presence of sufficient O2 to combust all or substantially all of the combustible component(s) present in said CO2 enriched stream. A CO2 product stream is formed from said combustion effluent. The support fuel stream may be generated from the process of generating or separating the gaseous mixture or from the H2/CO product stream. Where the CO2 enriched stream contains H2S, the support fuel stream may also be a stream obtained off-site that comprises H2S.
147	METHOD FOR PROVIDING AUXILIARY POWER TO AN ELECTRIC POWER PLANT USING FISCHER-TROPSCH TECHNOLOGY	US13406495	2012-02-27	US20120153639A1	2012-06-21	Dennis L. YAKOBSON; Claude C. Corkadel, III; Charles B. Benham; Belma Demirel; Peter S. Pedersen
A method for meeting both base-load and peak-load demand in a power production facility. By integrating a Fischer-Tropsch (FT) hydrocarbon production facility with an electrical power generating facility, peak-load power demand can be met by reducing the temperature of the FT reactor thereby increasing the quantity of tail gases and using FT tail gases to fuel a gas turbine generator set. The method enables rapid power response and allows the synthesis gas generating units and the FT units to operate with constant flow rates.

The present invention provides a series of processing steps to remove carbon dioxide from synthesis gas. The syngas exiting a hydrogen sulfide absorber is first compressed, subjected to a dehydration step and a low temperature liquefaction and separation to remove carbon dioxide. The high pressure syngas then continues on to a carbon dioxide absorber for carbon dioxide removal. The system can operate with lower solvent rates and equipment sizes compared to prior art systems.

157	High recovery carbon monoxide production process	US10671404	2003-09-25	US07066984B2	2006-06-27	Graeme John Dunn
The present invention provides for a monolith reactor process for the production of syngas from hydrocarbon and oxygen feeds. The syngas is cooled and separated to produce carbon monoxide and hydrogen, and the purification equipment utilized in this separation process recycles tail gas and fuel gas to the syngas feed gas line and recycles methane from the carbon monoxide separation system for feed back to the monolith reactor. This process results in almost complete carbon to carbon monoxide conversion and very high carbon monoxide and hydrogen recoveries.

A process is presented for separating and removing acid gases or base gases from a feed gas by use of a gas permeable membrane and a permeate comprising a treatment solution. The treatment solution in the permeate is caustic or acidic and reacts with the base or acid gases respectively to form salts so as to facilitate their removal from the feed gas. The acid gas in an acid feed gas may include HCN, H2S, CO2, COS and/or NOx. The base gas in a base feed gas may include NH3. In another aspect of the present invention, an apparatus for treating a feed gas containing an acid or a base gas comprises a feed gas passage; a treatment solution container containing a treatment solution; and a gas permeable membrane.

A process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification, wherein the aqueous effluent contains ammonium chloride (NH.sub.4 Cl). The aqueous effluent is evaporated to produce a distillate water and a brine having an NH.sub.4 Cl concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate water is recycled to the gasification reaction. No effluent discharges to the environment.
