||15173662||Robert James Rapp||Andrew David Hospodor|
A process and apparatus for extracting cannabinoids from cannabis plant material plant material and for transporting low concentrations of cannabinoids in a solution of solvent may include a solvent tank, a hopper, and one or more pumps. A plurality of valves may also be incorporated into the invention. Plant material may be soaked, washed, and/or rinsed with a solvent that extracts essential elements from cannabis plant matter. The process may minimally include filling a hopper with plant mater, moving solvent from a solvent tank to the hopper, and moving solvent back to the solvent tank after an extraction. Repeating this process a plurality of times with new plant material increases the concentration cannabinoids in the solvent tank after each time the process is performed.

The invention relates to a system and method of treating a flow back fluid exiting a well site following stimulation of a subterranean formation. The invention utilizes a two-stage membrane process during the period that the gas contains high concentrations of CO2 by volume, and allows for separation of CO2 from the natural gas components, providing pipeline-quality natural gas (approximately 5% CO2 by volume) to the gas collection system
20160279563 METHOD AND SYSTEM FOR GAS SCRUBBING OF AEROSOL-CONTAINING PROCESS GASES||US||29.09.2016|
||15022364||RWE POWER AKTIENGESELLSCHAFT||Tobias GINSBERG|
The invention relates to a method and to a system for gas scrubbing of aerosol-containing process gases using an amine-containing solvent as scrubbing agent, which is brought into contact with the process gas in an absorber column (9) and which is regenerated in a desorber column (13) and after cooling is delivered to the absorber column (9) again. The water vapour concentration of the process gas which is not saturated with water vapour is increased with water before the gas scrubbing in the absorber column (9), preferably to a degree of saturation of >0.8, such that water is condensed out of the gas phase on aerosol particles contained in the process gas, and in a following method step the aerosol particles which have grown in size are precipitated out of the process gas before the gas scrubbing.
20160279566 PROCESS FOR REMOVING MERCAPTANS FROM A GAS STREAM||US||29.09.2016|
||15036130||SHELL OIL COMPANY||Jozef Jacobus Titus SMITS|
The present invention relates to a process for removing mercaptans from a gas stream. First, a gas stream comprising at least a mercaptan of the general formula R1—SH, wherein R1 is an alkyl group comprising 1 to 4 carbon atoms, may be contacted with an absorption medium comprising a solvent, a substituted disulfide of the general formula R2—SS—R3 wherein R2 and R3 are carbon comprising substituents of which the corresponding R2—SH and R3—SH thiols have a vapour pressure below the vapour pressure of any R1—SH thiol and at least one of R2 and R3 is an electron withdrawing group; and at least a catalytic amount of a base. The absorption medium may be retrieved and regenerated in a regeneration unit. The regenerated absorption solution may be recycled and subjected to oxidation.

||15177579||NEW LIME DEVELOPMENT SPRL||Philippe Dumont|
The present invention relates to a hydrated-lime-based composition, to a method for producing such a composition and to the use thereof for treating fumes or flue gases (by means of a dry or substantially dry treatment process), in particular to reduce the chlorine, sulphur and halogen compounds in exhaust gases or flue gases, especially acid flue gases. Said composition comprise a high surface area hydrated lime, a first additive selected from NaCl, Na2SO4 and CaCl2, a sodium compound selected from NaOH, Na2CO3 and NaI— and less than 5% by weight water.
20160279568 FLUE GAS TREATMENT USING KRAFT MILL WASTE PRODUCTS||US||29.09.2016|
||15172255||S&S Lime, Inc.||John C. Stuever|
The present invention relates in general to a process for removing mercury from a mercury-containing flue gas using dregs from a Kraft pulp mill green liquor clarifier. The dregs are washed with water to produce a particulate carbon slurry which is activated with hydrobromic acid and injected into a mercury-containing flue gas to oxidize and adsorb the mercury at temperatures less than about 900° F. A slurry of sodium hydroxide and calcium carbonate, optionally also obtained from Kraft mill waste, is injected into the hot flue gas to absorb and remove CO2, SO2, and SO3.
