Abstract:
1. A method of controlling a gaseous reactant which comprises: supplying a gaseous reactant from a gas feed system to a compressor via a first feed line, continuously supplying the gaseous reactant pressurized by the compressor to a pressurized reaction system via a second feed line, and circulating or returning an amount of the gaseous reactant corresponding to an amount in excess in the reaction system from the second feed line to the first feed line via a circulation line that branches from the second feed line, to join the circulated gaseous reactant with the gaseous reactant in the first feed line at a junction of the first feed line and the circulation line, wherein a circulation flow rate of the gaseous reactant in the circulation line and a feed flow rate of the gaseous reactant from the gas feed system to the first feed line are controlled based on the pressure fluctuation of a gaseous phase in the reaction system, and the gaseous reactant comprises carbon monoxide and the reaction system is a carbonylation reaction system.
