Publication number: 20160200586Abstract: The invention provides an oxygen Andrussow process for production of hydrogen cyanide from a methane-containing feedstock such as natural gas in the presence of oxygen and ammonia over a platinum catalyst, wherein the production of byproduct organonitrile impurities, such as acrylonitrile, is reduced. Limiting the content of C2 hydrocarbons in the methane feedstock in the oxygen Andrussow process, in contrast to the air Andrussow process, has been found to reduce formation of organonitriles, such as acrylonitrile. The organonitrile impurities can require additional processing for removal cause fouling of equipment, and can also contribute to hydrogen cyanide polymerization. Reduction of C2+ hydrocarbon levels to less than 2 wt %, or 1 wt %, or less than 0.1 wt %, in the methane can provide an improved yield of higher purity HCN.Type: ApplicationFiled: December 12, 2013Publication date: July 14, 2016Applicant: INVISTA TECHNOLOGIES S.A R.L.Inventors: Stewart FORSYTH, Aiguo LIU, Martin J.

Publication number: 20160046499Abstract: Processes and systems for the production of hydrogen cyanide via the Andrussow process are described. A reaction zone, wherein oxygen, ammonia, and methane can be allowed to react in the presence of a catalyst comprising platinum to provide hydrogen cyanide. A desulfurization zone, wherein a feed stream comprising sulfur and at least one of the oxygen, the ammonia, and the methane can be contacted with a desulfurization material to produce a sulfur-reduced feed stream that is provided to the reaction zone. In an example, the desulfurization material includes zinc oxide.Type: ApplicationFiled: December 12, 2013Publication date: February 18, 2016Applicant: INVISTA NORTH AMERICA S.A R.L.Inventors: Stewart FORSYTH, Aiguo LIU, Martin J.

Publication number: 20150352481Abstract: A method and a system for recovering hydrogen from a process for making hydrogen cyanide are described herein. In the method, hydrogen is recovered from a gaseous waste stream of an Andrussow process. The method comprises the following steps: (a) adjusting a reaction mixture comprising methane, ammonia and oxygen to provide the reaction mixture with sufficient oxygen to generate a gaseous waste stream that has at least 40% hydrogen after removal of ammonia and recovery of hydrogen cyanide; and (b) removing components from the gaseous waste stream to generate recovered hydrogen.Type: ApplicationFiled: December 12, 2013Publication date: December 10, 2015Applicant: INVISTA NORTH AMERICA S.A R.L.Inventors: Stewart FORSYTH, Aiguo LIU, Martin J. RENNER, Brent J. STAHLMAN
