摘要:
A system and a method for removing gas field chemicals from a feed stream are provided. An exemplary method includes performing a forward osmosis on a feed stream including gas field chemicals to form a concentrated feed stream, and treating the concentrated feed stream in an electrochemical process to form treated water.
摘要:
The methods improve the separation of hydrocarbon containing fluids. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the methods use a first three-phase gas separation stop followed by indirect heating and then a second three-phase gas separation step. Pressure reduction of the hydrocarbon containing fluid occurs either before or after the indirect heating.

Volatile organic compounds are removed from crude oil by adding heat upstream of a vapor recovery tower. The heat input may either be sufficient to break the emulsion as in a here treater or extra heat may be added to stabilize the crude oil. Produced gas may be recovered as NGL in one or more cooling stages. Produced gas, whether partially recovered or not, may be used as fuel for said heater treater, other combustion device or compressed into a pipeline.
摘要:
Systems and methods of integrated gas oil separation are disclosed. Systems include a high pressure production trap (HPPT), a low pressure production trap (LPPT), a low pressure degassing tank (LPDT), a first knockout drum (KOD) fluidly coupled to the LPDT and operable to accept an atmospheric pressure off-gas from the LPDT, an atmospheric pressure compressor fluidly coupled to the first KOD and operable to compress the atmospheric pressure off-gas to introduce the atmospheric pressure off-gas from the LPDT into the LPPT inlet feed stream, a second KOD fluidly coupled to the LPPT and operable to accept a low pressure off-gas from the LPPT, and a low pressure compressor fluidly coupled to the second KOD and operable to compress the low pressure off-gas to introduce the low pressure off-gas from the LPPT into the crude oil inlet feed stream.
摘要:
There is disclosed a system and method for processing diesel fuel from petroleum-based waste oil on a small scale compared to conventional methods for re-refining waste oil to a valuable product. In an embodiment, the method comprises dehydrating waste oil to remove water from the waste oil, and operating a thermal reactor to induce thermal pyrolysis of the dehydrated waste oil and convert it into a hydrocarbon vapor phase. The hydrocarbon vapor derived from pyrolysis is condensed and distilled using a distillation tower to produce diesel fuel, heavy liquid hydrocarbon, light liquid hydrocarbon and light hydrocarbon vapor. A filtering step cleans the processed diesel fuel to obtain a clean diesel fuel product.
摘要:
There is described a process for producing biodiesel and related products from mixtures. There is also described a process for producing precursors and feedstock materials for producing biodiesel and related products. The processes use esterification and trans-esterification, separation and purification. Other process steps such as acidification and distillation can also be used.
摘要:
Eco-friendly systems, methods and processes/processing (EFSMP) or an integrated Matrix encompasses stand-alone and/or interconnected modules for completely self-sustained, closed-loop, emission-free processing of multiple source feedstock that can include pretreatment, with poisoning materials isolated during pretreatment being further recycled to provide useful materials such as, for example, separated metals, carbon and fullerenes for production of nano materials, sulfur, water, sulfuric acid, gas, heat and carbon dioxide for energy production, and production of refined petroleum, at a highly-reduced cost over the best state-of-the-art refining methods/systems that meets new emissions standards as well as optimizes production output with new ultra-speed cycle times. By-products from the petroleum refining process which were previously discarded also now are recycled as renewable sources of energy (water, waste oil and rubber/coal derived pyrolyic (pyrolysis) oil, carbon gases and process gases), or recyclable resources, such as metals and precious metals, oxides, minerals, etc., can be obtained.
摘要:
A process for removing at least one product from coal tar is described. The process involves extraction with an extraction agent or adsorption with an adsorbent. The extraction agent includes at least one of amphiphilic block copolymers, cyclodextrins, functionalized cyclodextrins, and cyclodextrin-functionalized polymers, and the adsorbent includes exfoliated graphite oxide, thermally exfoliated graphite oxide or intercalated graphite compounds.
摘要:
Feeding a slurry comprising inert solids, liquid hydrocarbons, liquid water and sometimes dissolves solids to a unit having a casing defining a thermal extraction chamber heated both directly and indirectly in which first and second intermeshing screws rotate, the screws in close tolerance with each other and with inside casing surfaces. The casing and screws define a tortuous flow path in which the slurry and a vaporous composition evolved therefrom flow. The intermeshing screws push the slurry toward a discharge end of the chamber at a first velocity while reducing pressure and increasing temperature in the chamber, while rotating the screws to create turbulent vacuum thermal conditions in the chamber to physically transform some or all of the slurry into the vaporous composition. The vaporous composition traverses the tortuous flow path with a second velocity at least 1.5 times the first velocity, optionally forming a heated, substantially dry, composition comprising the inert solids.
摘要:
A process for the extraction and recovery of bitumen from oil sands using deionized silicate solutions. Bitumen is recovered in a process comprising contacting a deionized silicate solution with an ore sand oil to produce a froth comprising bitumen and a tailings stream comprising water, sand and clay fines and optionally unrecovered bitumen. Preferably the tailings stream is dewatered and recovered water may be recycled to the extraction process.
