Abstract

Esta invención se refiere a un procedimiento para separar el HCN de un gas de síntesis que contiene H2, CO, CO2, etc, obtenido por oxidación parcial de un combustible hidrocarbonado. El gas de síntesis se enfría a 148-485ºC, opcionalmente después de separar los sólidos, y se lava con agua. La corriente limpia resultante se enfría, se separa el agua condensada y la corriente gaseosa se purifica por contacto con un absorbente acuoso líquido. Mediante este procedimiento, se consigue separar el HCN sin alterar la relación molar H2/CO del gas de síntesis.
