PROBLEM TO BE SOLVED: To provide a method and system for purification of a source gas, which is capable of efficiently removing a low-concentration lower hydrocarbon remaining in the source gas having been purified by a usual method, such as a coke oven gas. SOLUTION: This system includes a source gas highly purifying device 12, which removes low-concentration lower hydrocarbon remaining in the source gas 11 containing methane, carbon monoxide, carbon dioxide and hydrogen as principal constituents having been purified by the usual method, and a desulfurization device 14 which desulfurizes a sulfur compound present in a highly purified gas 13 having been purified by the source gas highly purifying device 12.
