Method and System for the Separation of a Mixture Containing Carbon Dioxide, Hydrocarbon and Hydrogen

ABSTRACT The invention provides a method and system for the separation of a mixture containing H2, hydrocarbon, and CO2. The generated mixture is introduced into a distillation column having a side stream to generate a top stream comprising H2, a middle (volatility) stream comprising hydrocarbon; and a bottom stream comprising CO2. In a preferred embodiment, the mixture further comprises N2 which is obtained in the top stream. In a most preferred embodiment, the H2 and the N2 are present in a molar ratio of 3 H2 :1 N2. The generated H2 and N2 may be used for the synthesis of ammonia. Thus, the invention also proves a method and system for the generation of ammonia Fig1: Syn-Gas Separation System (Side stream withdrawn from reboiler)
