Stabilization and control of biochemical process cycles within sealed dump for methane reactivation, comprises anaerobic ventilation of the dump area by filling saturated water vapor and dump gas and mixing the vapor with moistened dump gas

摘要

The water vapor is produced by exhaust gases of fuel combined heat and power station (11) and/or stationary fluidized-bed combustion (12). The water vapor and/or saturated dump gas are transported over inactive and disturbed wells (2.1-2.7). The heat and power station and/or the fluidized-bed combustion are operated with the dump gas in dependence of methane portion of less than 40 vol% of the dump gas. Precipitation water and/or dump seeping water or tap water is fed into evaporation system. The dump gas is sucked off from the dump. The heat energy of the station and the fluidized-bed combustion is supplied from inert bed to heat exchanger evaporator (15) for steam generation. The heat/water content (30%) of the dump gas is adjusted in the dump for the anaerobic ventilation. The biochemical heat of reaction takes place at 20-30[deg]C for the methane production. Moistening of the gas flow to adjustment of the steam temperature takes place in the gas bypass line (26) after mixing of the water vapor with the dump gas. The anaerobic ventilation of the dump takes place partially over individual reaction-weak well or summarized groups of wells and on gas suction side and gas and/or water vapor inlet side. The biochemical process cycles are controlled and stabilized by electronic data processing mechanism. An independent claim is included for a mechanism of execution of stabilization and control of biochemical process cycles.
