Abstract: The present invention relates to an improved process for producing hydrogen cyanide. More particularly, the present invention relates to a commercially advantageous process for producing hydrogen cyanide at enhanced levels of productivity and yield while using natural gas comprising at least one C2+ hydrocarbon, carbon dioxide, and hydrogen sulfide. The natural gas is purified to be used as a source of methane-containing feedstock.

Abstract: The present invention relates to an improved process for producing hydrogen cyanide involving a heat exchanger comprising a plurality of tubes, wherein each of the plurality of tubes comprises a ceramic ferrule extending through the entrance of the tube, each ferrule comprising an insulation layer surrounding at least a portion of the ferrule, and one or more washers, wherein at least one of the one or more washers surrounds the ferrule above the entrance of the tube, wherein the ceramic ferrule is spaced apart from the tube. It further relates to a reaction apparatus for producing hydrogen cyanide involving a heat exchanger comprising a plurality of tubes, wherein each of the plurality of tubes comprises a ceramic ferrule extending through the entrance of the tube, each ferrule comprising an insulation layer surrounding at least a portion of the ferrule, and one or more washers, wherein at least one of the one or more washers surrounds the ferrule above the entrance of the tube, wherein the ceramic ferrule is spaced apart from the tube. It further relates to the heat exchanger for use in this improved process and reaction apparatus.

Abstract: Described is a process for the production and recovery of hydrogen cyanide, which includes recovering hydrogen from a crude hydrogen cyanide product. The process includes forming a crude hydrogen cyanide product and separating the crude hydrogen cyanide product to form an off-gas stream and a hydrogen cyanide product stream. The off-gas stream is further separated to recover hydrogen. The hydrogen cyanide product stream is further processed to recover hydrogen cyanide.
