FERMENTATION APPARATUS FOR METHANE-ASSIMILATING MICROORGANISMS Russian patent published in 2016 - IPC C12M1/02 C12M1/04 C12M1/36 C12Q3/00 

FIELD: biochemistry.

SUBSTANCE: invention relates to the field of biochemistry. Disclosed is a fermentation plant for methane-assimilating microorganisms. Plant comprises a column fermenter and two reactors. Fermenter comprises a housing, an exhaust gas outlet pipe, a tube for feeding nutrient salts, process water, food components and seed biosuspension, a pipe for inlet of gas-liquid flow into fermenter from reactor and a pipe for outlet of biosuspension from fermenter into reactor. Each reactor comprises a sampling tube for gas-liquid flow in fermenter, a disc mixer with a drive, a pipe for feeding biosuspension from fermenter into reactor. First reactor comprises a pipe for feeding methane-containing gas, second reactor comprises a pipe for feeding oxygen-containing gas. Fermenter additionally contains temperature maintenance means, means of maintaining pH of medium, means of maintaining level of dissolved oxygen, exhaust gas analyser. Mixer drive in each reactor is equipped with power transducer connected via logical device controller with flow rate regulators of incoming gas flows and with control valves of supply of liquid in each reactor.

EFFECT: invention reduces power consumption on process of aerobic fermentation, high degree of usage of oxygen and methane, increased efficiency, as well as possibility of making efficient industrial plants with volume of up to 100-400 m³.
