A waste treatment system, includes: at least one reformer for hydrolyzing waste; a microbial reactor for microbially degrading a reformed material containing at least a solid of the waste hydrolyzed by the at least one reformer; a microbial reaction detection device for detecting a state of degradation of the reformed material in the microbial reactor; and an adjustment device for adjusting amount and timing of supply of the reformed material to the microbial reactor, based on a detected value of the microbial reaction detection device.

Waste treatment system and waste treatment method

A COrecovery unit includes an absorber that reduces COin flue gas () discharged from a combustion facility () by absorbing COby an absorbent, a regenerator that heats the absorbent having absorbed COto emit CO, and regenerates and supplies the absorbent to the absorber, and a regenerating heater that uses steam () supplied from the combustion facility () for heating the absorbent in the regenerator and returns heated condensed water () to the combustion facility (). The COrecovery unit further includes a condensed water/flue gas heat exchanger () that heats the condensed water () to be returned from the regenerating heater to the combustion facility () by heat-exchanging the condensed water () with the flue gas () in a flue gas duct () in the combustion facility ().

[object Object]

A COrecovery unitA according to a first embodiment has a COabsorber that removes COin flue gas by bringing the flue gas containing COinto contact with a COabsorbent, and a regeneratorthat diffuses COin a rich solutionhaving absorbed COin the COabsorber. The COrecovery unitA includes a first compressor-to a fourth compressor-that compress COgasdischarged from the regenerator, a dehydrating columnthat reduces moisture in the COgasby bringing the COgasinto contact with a dehydrating agent, a combustion removal unitthat removes the dehydrating agentmixed in the COgasin the dehydrating column, and a heat exchangerthat performs heat exchange between the COgasdischarged from the third compressor-and the COgasdischarged from the dehydrating column

CO2 recovery unit and method therefor

A gas-liquid contacting plate of the present invention in which a treatment liquid flows from an upper side to a lower side direction of a substrate and a part of gas being in contact with the treatment liquid is absorbed into the treatment liquid, includes a downward protruding saw teeth-shaped portion in which a lower end side of the substrate has pitches at predetermined gaps. Further, a pore group for liquid dispersion having a predetermined gap is provided in a plurality of lines, in the substrate. An arrangement thereof is a zigzag arrangement.

A CO shift catalyst according to the present invention reforms carbon monoxide (CO) contained in gas. The CO shift catalyst is prepared from one or both of molybdenum (Mo) and cobalt (Co) as an active ingredient and an oxide of one of, or a mixture or a compound of, titanium (Ti), silicon (Si), zirconium (Zr), and cerium (Ce) as a carrier for supporting the active ingredient. The CO shift catalyst can be used in a halogen-resistant CO shift reactor () that converts CO contained in gasified gas () generated in a gasifier () into CO.
