摘要： Methods and systems for producing aromatics and light olefins from a mixed plastics stream are described. The method may include feeding a plastic feedstock to a dechlorination operation to melt the plastic feedstock to release HCl and generate a liquid plastic stream; feeding the liquid plastic stream to a pyrolysis reactor, the pyrolysis reactor to generate hydrocarbon vapors; feeding the hydrocarbon vapors to an acid gas removal reactor with a solid inorganic alkali salt disposed within the reaction vessel to remove residual HCl and sulfur-containing compounds from the hydrocarbon vapors to generate a plastic derived oil; and feeding the plastic derived oil to a fluid catalytic cracking reactor to generate a product stream comprising light olefins having a carbon number of C2-C4 and aromatics. The associated system for processing mixed plastics into aromatics and light olefins is also described.

摘要： A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

摘要： An apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat can be recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger that is coupled with the thermal oxidizer. Cooled flue gas is mixed with hydrated lime, enhancing PFAS decomposition, with the spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements. The apparatus and methods thereby eliminate PFAS from wastewater biosolids and control emissions in the resulting flue gas.

摘要： Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

摘要： The invention pertains to methods of reducing dissolved elements such as arsenic, selenium and mercury in aqueous solutions using, for example, various barium compounds to partition said elements to a solid phase. Such methods are particularly useful for reducing such elements at various points in coal and oil-fired power plants prior to final waste water treatment.

摘要： Systems and methods for generating power using hydrogen fuel, such as derived from natural gas, are provided. Feed materials are introduced into a compact hydrogen generator to produce carbon dioxide, hydrogen gas and steam. Sorbent material within the compact hydrogen generator acts to absorb carbon dioxide, forming a used sorbent. Hydrogen gas and steam are separated from the used sorbent and passed to a power generator such as a hydrogen turbine to produce power. The used sorbent is introduced into a calciner and heated to desorb carbon dioxide and form a regenerated sorbent which can be recycled to the compact hydrogen generator.

摘要： Organic sulfur compounds contained in refinery off gas streams having either high or low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.
