20150315490 | SYSTEMS AND METHODS FOR INCREASING DEASPHALTED OIL YIELD OR QUALITY - Systems and methods are provided for deasphalting with integrated hydrodynamic cavitation to improve the yield or quality of deasphalted oil obtained from a deasphalting unit. | 11-05-2015 |
20150059368 | UTILIZATION OF WASTE HEAT USING FIBER SORBENT SYSTEM - A method for creating work by adsorption end desorption of a working fluid on an fiber sorption system which has a plurality of tubular hollow fibers within a vessel which is connected to a work device. Each fiber is in the form of a tubular, elongated body composed of a sorbent material capable of adsorbing a working fluid such as carbon dioxide. The fibers have an inner surface adjacent the hollow interior and an outer surface, one of which has a coating layer which is impermeable to both a working fluid and thermal fluid. The system is operated by passing a thermal cooling fluid in contact with the fibers to cool the fibers and passing the working fluid over the fibers in contact with the surface of the cooled fibers which does not have the coating layer so that the working fluid is adsorbed on the fibers, the adsorbed working fluid is then desorbed from the fibers by passing a thermal heating fluid in contact with the fibers to heat the fibers; the pressurized, desorbed working fluid is then passed to a work device connected to the vessel. | 03-05-2015 |
20130095544 | Pond System for Algae Growth and Harvesting - Management of a pond for algae growth and harvesting is facilitated by use of a cover system. The cover system can include one or more types of cover portions for management of various interactions between a pond and an ambient environment, such as management of incident light, thermal management, facilitating product recovery, and management of gas diffusion. The cover system can be used in conjunction with both active and passive mixing devices. | 04-18-2013 |
20110165355 | Process For Making Polyol Neoalkylester Plasticizers From Neo Acids - Provided are compositions, processes for making, and processes for using neoalkyl polyol esters and triglycerides as plasticizers. In one form, a neoalkylester triglyceride plasticizers can be produced by (i) drying a polyol feedstream; (ii) contacting in a reactor the dried polyol feedstream with a neoacid feedstream under effective temperature, pressure and time to form a neoalkylester plasticizer effluent stream, and (iii) purifying the neoalkylester plasticizer effluent stream to remove unreacted polyol and unreacted neoacid to form a neoalkylester plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or pour point, glass transition temperature, low volatility, increased compatibility, increased hydrolytic stability, and excellent low temperature properties in a range of polymeric resins. | 07-07-2011 |
20110160371 | AROMATIC ACYLATION WITH CYCLIC ANHYDRIDE FOR PLASTICIZER PRODUCTION - Provided is a process for making non-phthalate plasticizers, by acylating an aromatic compound with a succinic anhydride to form a keto-acid, and then esterifying the keto-acid with C | 06-30-2011 |
20100326410 | EXPANDING THE OPERATING ENVELOPE OF ADVANCED COMBUSTION ENIGINES - The invention provides enriched fuels and methods that expand the operating envelope of an advanced combustion engine during operation in an advanced combustion mode (e.g. HCCI mode). Enriched fuels and methods of the invention facilitate efficient combustion over a wide range of engine loads, and the need for EGR, VVT, NVO, rebreathing, or multiple fuel injection is either reduced or eliminated. | 12-30-2010 |
20100151397 | SYSTEM AND METHOD FOR CONTROLLING FIRED HEATER OPERATIONS - Method of controlling the operation of a combustion device to provide safe and reliable operation while reducing NOx emission that includes providing a flow of fuel and diluent at a determined volume ratio to a flame in the combustion device; providing a flame stability sensor to generate a measurement of a characteristic of the flame, providing a flow measurement for each of the fuel and diluent, and controlling the determined volume ratio of fuel:diluent using the measurement from the flame stability sensor and/or flow measurements. A combustion system incorporating this method also is included. | 06-17-2010 |
20100078305 | Scrubber for fluid coker unit - Fouling in the scrubber section of a fluid coker unit is reduced by providing baffles to improve the uniformity of the gas flow profile in the scrubber by reducing the gas velocity of the cyclone outlet gases in the scrubber section of the unit. These baffles are located with the objective of reducing the rotational component of the gas flow in the scrubber created by the alignment of the gas outlets of the cyclones. The baffles are preferably located in the shed section of the scrubber and comprise upstanding perforated plates located at the periphery of the scrubber section to disrupt high velocity gas jets in the region of the interior wall of the scrubber. | 04-01-2010 |
20100059357 | Coking drum support system - A delayed coking unit with a coking drum having an upper cylindrical portion and a lower frusto-conical portion is supported by means of a support structure surrounding the cone frustum of the lower portion of the drum; the support structure comprises a cone support member having a concave frusto-conical support surface mating with the outer convex cone frustum of the lower portion of the drum so that the drum sits in the cone support element. The support structure further has a weight supporting member or members attached to the cone support member intermediate its upper and lower peripheries which acts or act to transfer the weight of the drum (and contents) downwards to a suitable sub-structure such as a concrete slab. In a preferred embodiment, the drum may also be stayed against lateral forces by means of guide members at the upper portion of the drum. | 03-11-2010 |
