Disclosed herein are a bed of materials and use of it for removing contaminants not limiting to carbon monoxide, oxygen, carbon dioxide, acetylene, hydrogen, water, carbonyl sulfide and hydrogen sulfide from lower olefins without limiting ethylene.

A flare gas recovery system includes an ejector that receives flare gas from a suction line extending from a flare gas header, and further receives a motive fluid that draws the flare gas into the ejector to be mixed with the motive fluid and discharge a recovered gas into a discharge gas line. A solid oxide fuel cell system receives the recovered gas and includes a fuel cell power module that uses the recovered gas to generate electrical power, an anode exhaust, and a cathode exhaust, a combustor that receives and combusts at least a portion of the anode and cathode exhausts and thereby generates waste heat, and a process gas heat exchanger that receives and converts the waste heat into electrical power.

A separation zone and a method of separating a mixed stream are described. The separation zone includes a tank and a stack having a gas outlet. A first baffle is positioned between the sides and defines a disulfide liquid compartment. The stack is positioned above the disulfide liquid compartment. A second baffle is positioned between the first baffle and the second side and defines an alkali compartment. The second baffle has a height less than the height of the first baffle. A third baffle is positioned between the first and second baffles. The bottom of the third baffle is at a height less than the height of the second baffle, and the top of the third baffle is at a height greater than the height of the first baffle.

Provided is a method for treatment of gas mixtures and an apparatus for carrying out a method for treatment of raw gas mixtures. More particularly, there is provided a method and an apparatus for treatment of gas mixtures, such as biogas or flare gas, and in particular to a method and an apparatus for removing contaminants, in particular H.sub.2S, from a gas mixture containing CH.sub.4 and H.sub.2S.

A method for the destruction of a target gas, the method including: a) compressing at a first pressure a mixture of air and target gas to produce a compressed target gas mixture; b) destroying the target gas by combusting the compressed target gas mixture with diesel fuel in a forced-induction internal combustion engine, at a combustion pressure greater than the first pressure in the turbocharger, to produce an oxidised exhaust gas, the combustion occurring while maintaining a load on the diesel engine with a load bank; and c) processing the oxidised exhaust gas to produce a vent gas for venting to atmosphere where the vent gas includes substantially no target gas.

The present invention is a pyrolysis system including a furnace for batch pyrolysis processing. The pyrolysis system receives scrap tires or other organic waste materials as inputs and performs batch pyrolysis processing to produce pyro-products as outputs. The pyro-products produced include pyro-vapors from which are condensed pyro-oil with a surviving pyro-gas and also include pyro-solids, particularly pyro-carbon (carbon char) and steel. The pyro-oil includes an inhibitor.

Technologies for combusting hazardous compounds such as chemical warfare agents and related compounds are disclosed. In embodiments, the technologies include systems and methods for combusting such compounds in an internal combustion engine, such as a spark ignition internal combustion engine, a diesel engine, or the like. The technologies described herein further include components for treating an exhaust gas stream produced by combustion of hazardous compounds. In embodiments such components include a scrubber that utilizes a scrubbing media such as soil to removing acid gases from the exhaust stream.

Herein are disclosed compositions of matter, processes of manufacture and processes of use of solid state admixtures that include an inorganic base and a sulfide selected from the group consisting of an ammonium sulfide, an alkali metal sulfide, an alkali-earth metal sulfide, transition metal sulfide, and a mixture thereof. The composition can include solid state inorganic bases (e.g., calcium hydroxide and sodium sesquicarbonate) and/or gaseous bases (e.g., ammonia) and, optionally, a support material for one or more of the inorganic base and sulfide. The compositions are useful for capturing environmental contaminants, for example, from the flue gas of a coal fired power plant.

The present invention relates to a combined C3/C4 splitter with a membrane system. More specifically, the present invention relates to a combined C3/C4 splitter column to separate highly pure propylene product from a liquefied petroleum gas stream, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires.

A system for recovering nitrogen during regeneration of a treater, the system including an adsorbent bed downstream of the treater, wherein the adsorbent bed comprises an adsorbent operable to adsorb at least one impurity from a treater bed regeneration effluent stream comprising nitrogen to provide a nitrogen product having a higher nitrogen purity than a nitrogen purity of the treater bed regeneration effluent stream. A method for recovering nitrogen during regeneration of a treater is also provided.
