A method and apparatus are described for supplying municipal solid waste (MSW), and/or other types of solid waste comprising both organic waste material and inorganic waste material, into a plasma gasifier reactor (PGR) in which the solid waste is to be processed.

Method and apparatus for feeding municipal solid waste to a plasma gasifier reactor

Sulfur dioxide (SO) is removed from a carbon dioxide feed gas by maintaining the feed gas at elevated pressure(s) in the presence of oxygen (O), water and NOfor a period of time sufficient to convert SOto sulfuric acid and NOto nitric acid and produce SO-depleted, NO-lean carbon dioxide gas. The invention resides in separating the sulfuric and nitric acids from said SO-depleted, NO-lean carbon dioxide gas, and then neutralizing the acids by reaction with an alkaline sorbent in an acid/sorbent reactor system to produce sorbent-derive sulfate. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a carbonaceous fuel.

Sulfur dioxide (SO) may be removed from carbon dioxide feed gas by contacting the carbon dioxide at an elevated temperature and an elevated pressure with a catalyst for oxidizing SO, in the presence of oxygen (O) to convert SOto sulfur trioxide (SO); contacting SOin the resultant SO-enriched carbon dioxide gas with water to produce sulfuric acid and SO-depleted carbon dioxide gas; and separating the sulfuric acid from the SO-depleted carbon dioxide gas. If present, NOis also removed from the carbon dioxide feed gas as nitric acid to produce SO-depleted, NO-lean carbon dioxide gas. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a hydrocarbon fuel or carbonaceous fuel, within or downstream of the COcompression train of a COrecovery and purification system.

Sulfur dioxide (SO) is removed from carbon dioxide feed gas comprising SOas a contaminant by maintaining the carbon dioxide feed gas at an elevated pressure in contact with an alkaline sorbent for a period of time sufficient to react said alkaline sorbent with SO. Where NO, oxygen (O) and water are also present, not only is the rate of reaction with the sorbent increased, but also additional SOis removed by conversion to sulfuric acid, and NOis removed as nitric acid. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a hydrocarbon or carbonaceous fuel.

Shear thinning vinyl acetate based polymer latex composition, especially for adhesives

A continuous emulsion polymerization process consisting of multiple stirred-tanks in series is used to produce a broad particle-size distribution for vinyl acetate-based emulsions utilizing polyvinyl alcohol as a protective colloid. When low-molecular-weight grades of PVOH and a continuous process are employed, a high-solids emulsion can be produced. This process eliminates the need for a co-surfactant, which is required to make similar high-solids emulsions via a batch process.

Vinyl acetate/ethylene high solids emulsions

This invention describes an integrated process for making ethylidene bisformamide in high yield wherein water, which is formed as a reaction by-product, is readily removed from the reaction product mixture without adversely affecting the efficiency of the overall process. The process contemplates isolating the reaction zone from the separation zone and comprises circulating a stream of formamide through a reaction zone containing a solid acidic catalyst and a separation zone; introducing acetaldehyde into the circulating stream of formamide to form a reaction mixture and contacting the reaction mixture with the solid acidic catalyst under reaction conditions sufficient to form a product mixture comprising ethylidene bisformamide and water; and separating water from the product mixture in the separation zone to form a water-depleted product mixture containing ethylidene bisformamide.
