Recirculation system for chemical processes comprises a first circuit containing a reactor, a cooling system, a separation apparatus, and a recirculation condensing device; and a second circuit, connected to the first by which the gases withdrawn from the first are led to a gas conversion apparatus, in which the reactants are separated. The reactants are then led via a compressor to the first circuit. For treating the gas mixture produced during the synthesis of methanol and ammonia. In addition, methane formed during gas separation, can be passed to a chlorination apparatus, so that the krypton and xenon present in the methane can be recovered. The method enables useful components, which would otherwise be lost, to be recovered for re-use. |
