Abstract:
A process and system for recovering natural gas liquids (NGL) using a combination of J-T cooling and membrane separation. The process involves compressing, separating, and cooling a flare gas stream comprising at least methane and C 3+ hydrocarbons prior to being introduced to a J-T valve. The cooled stream exiting the J-T valve is further separated, producing a NGL product stream and an uncondensed gas stream. The uncondensed gas stream is directed to a membrane separation step, which results in a C 3+ hydrocarbon enriched stream and a C3+ hydrocarbon depleted stream. The C 3+ hydrocarbon enriched stream may be recycled back to the process to recover more NGL.
Abstract:
A system (100) of converting solid waste of plastics/rubber into hydrocarbon fuel, said system (100) comprising: (i) a thermal cracking reactor (110) for cracking the solid waste and a catalyst as feed at a temperature in the range of 200-475 °C to obtain a catalytic thermal cracking product containing a gaseous hydrocarbon stream and a coke residue; and (ii) a condenser (120) for receiving said gaseous hydrocarbon stream and cooling said gaseous hydrocarbon stream to obtain an at least partly condensate stream containing a liquid hydrocarbon oil of smaller molecules and non-condensable gaseous hydrocarbons, wherein said thermal cracking reactor (110) having an operative top side-wall (103) and an operative bottom side-wall (105) is positioned in horizontal and comprising a feed inlet (104) at one end and a gas outlet (116) at an opposite end on said operative top side-wall (103), a residue outlet (118) at said operative bottom side-wall (103), and an agitator device (106) centrally positioned between said side-walls (103, 105) along the operative longitudinal axis of said reactor (110), and wherein the condenser (120) is in operative communication with said gas outlet (116 ) of said reactor (110). A method of converting plastic/rubber to hydrocarbon by thermo-catalytic process is also disclosed.
Abstract:
The invention relates to a method and apparatus for treating waste material including organic components and radioactive agents. According to the invention, the method comprising steps: the waste material including organic components and radioactive agents is gasified at temperature between 600 –950 ºC in a reactor to form a gaseous material; the gaseous material is cooled so that temperature is between 300 –500 ºC after the cooling; and solid fraction including radioactive agents is removed from the gaseous material in a gas cleaning step, in order to form a treated gaseous material. Further, the invention relates to a product gas.

Abstract:
A pyromellitamide or benzamide, previously disclosed for use as a gelling agent in a downhole fluid, is added to a hydrocarbon fluid for use as a friction reducing agent, for example in a motor or pipeline. An example pyromellitamide friction reducing agent may have the general formula (I) of: with R 1 , R 2 , R 3 , and R 4 each being an organic group. A further use as a viscosity reducing agent in diluted bitumen is also disclosed.
Abstract:
The invention relates to a process for the production of an agglomerated coal product from a coal fines feedstock, the process comprising a step of mixing the feedstock with a binder comprising sodium silicate and a surfactant and optionally PVA and/or a waterproofing agent in a mechanical mixer to produce the agglomerated coal product and an agglomerated coal product produced by the process of the invention. The process may further comprise a step of drying or curing the agglomerated coal product.
Abstract:
A blendstock for forming a fuel composition for use in internal-combustion engines, includes a polar fluid component, a microblender component, and a neutralizer component. The neutralizer component is present in an amount effective to substantially neutralize the microblender component to allow for the microblender component to substantially spontaneously blend with the polar fluid component. The polar fluid component may include a water component and an alcohol component, and the neutralizer component may include an ammonia component. The blendstock may be added to a hydrocarbon fuel, such as diesel fuel, to form the fuel composition.
