Abstract: Provided is a method which allows, for example, suppression of foaming in the purification step such as distillation and continuous operation, as well as direct treatment of a waste liquid (can liquid) without having to subject the same to an extra purification treatment by removing the microorganisms, nitrogen compounds, and phosphorous compounds at once from an organic substance-containing liquid obtained from microbial fermentation. Also disclosed is a method for producing an organic substance, comprising a microbial fermentation step, a separation step, a liquefaction step, and a second purification step, wherein the concentration of the nitrogen compound in the second can liquid is 0 to 150 ppm based on the total mass of the second can liquid, and the concentration of the phosphorous compound in the second can liquid is 0 to 5 ppm based on the total mass of the second can liquid.

Abstract: Provided are a method for producing an organic substance and an apparatus for producing an organic substance that are capable of efficiently cooling a synthesis gas and converting the synthesis gas to an organic substance at a high conversion efficiency using a microbial catalyst. A method for producing an organic substance includes a step of passing a synthesis gas G1 discharged from a gasifier 2 through a heat exchanger 20 to cool the synthesis gas G1, a step of passing the synthesis gas G1 cooled with the heat exchanger 20 through a gas cooling tower 21 to cool the synthesis gas G1 with water sprayed in the gas cooling tower 21 and a step of bringing the synthesis gas G1 that has passed through at least the heat exchanger 20 and the gas cooling tower 21 into contact with a microbial catalyst to generate an organic substance.
