| 20090104099 | RICH GAS ABSORPTION APPARATUS AND METHOD - The present invention relates to an apparatus comprising a co-current absorbing unit, a countercurrent absorbing unit, at least one absorbing liquid reservoir, and at least one liquid transferring means. The invention also relates to a method of absorbing a reactive gas and a method of preparing a solution by contacting a reactive gas to a solvent and allowing the reactive gas to react with the solvent. | 04-23-2009 |
| 20100069515 | MIXED ALCOHOL SYNTHESIS WITH ENHANCED CARBON VALUE USE - The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream. The present invention also provides downstream processing of the mixed alcohol or mixed oxygenate product by subjecting the product to a dehydration step in order to convert at least ethanol, preferably at least ethanol and propanol, to their corresponding olefins (e.g. ethylene and propylene). | 03-18-2010 |
| 20100288167 | LOW DIOL CONTENT MONOFUNCTIONAL ALKOXYPOLYALKYLENE GLYCOLS AND PROCESS FOR PRODUCING THEM - Provided is a process for preparing low diol content monofunctional polyalkylene glycols. The process includes introducing the initiator feed in two portions (a first and second initiator) and drying only the first initiator to remove water. The first and second initiators can be the same or different. Also provided are new monofunctional polyalkylene glycol compositions. | 11-18-2010 |
| 20110092748 | Process For Nitroalkane Recovery By Aqueous Phase Recycle To Nitration Reactor - Disclosed are a process and an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. Energy and capital costs may be reduced by recycling a majority of the aqueous phase back to the reactor. | 04-21-2011 |
| 20110092749 | Process For Downstream Recovery Of Nitroalkane Using Dividing Wall Column - Disclosed are a process and apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. Energy and capital costs may be reduced by using a dividing wall column. | 04-21-2011 |
| 20110160496 | HYDROCARBON FEED FLEXIBLE HIGH PRESSURE NITRATION PLANT DESIGN - Disclosed is an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. The apparatus may be designed such that it can synthesize more than one nitroalkane using the same equipment. | 06-30-2011 |
| 20110172458 | Apparatus, Systems, and Methods for Purification of Isocyanate Mixtures - The present disclosure relates, according to some embodiments, to apparatus, systems, and/or methods for fractionating a feed mixture comprising, for example, one or more isocyanates, light components, solvents and/or heavier components. In some embodiments, fractionating an isocyanate feed mixture may comprise distilling the feed mixture in a non-adiabatic fractionating apparatus comprising a prefractionating section and/or column and a main section and/or column, which comprises a rectification section, a side section, and a stripping section. For example, isocyanates may be separated from light component(s), solvent(s) and/or heavier component(s). A fractionating apparatus may be configured and arranged, in some embodiments, as a dividing wall column. According to some embodiments of the disclosure, apparatus, systems, and/or methods may be energy efficient and/or may have a broad operating range. | 07-14-2011 |
| 20110257445 | PROCESS FOR SEPARATING CHLORINATED METHANES - The present invention relates to a process for separating chlorinated methanes utilizing a dividing wall column. Processes and manufacturing assemblies for generating chlorinated methanes are also provided, as are processes for producing products utilizing the chlorinated methanes produced and/or separated utilizing the present process(es) and/or assemblies. | 10-20-2011 |
