摘要:
The gas-liquid contact plate is constructed so that a plurality of straight rows are provided; irregularities are formed over both surfaces of the plate at equal intervals in the row; the adjacent rows have repeated irregularities opposite to each other; and in a peak or valley portion of the irregularities, there is formed an opening connecting the surface to the back surface between the adjacent rows. There is provided a gas-liquid contact plate that has high wettability, being capable of improving the gas-liquid contact efficiency, and is light in weight and advantageous in terms of manufacturing cost.

A CO2 reducing system (10A) is constituted by a low-temperature CO2 reducing apparatus (11-1) that includes a low-temperature absorber (1006-1) that reduces at least one of CO2 and H2S by bringing flue gas (1002) including at least one of CO2 and H2S into contact with a low-temperature absorbing solution (1005-1), a low-temperature regenerator (1008-1) that regenerates a low-temperature rich solution (1007-1), a low-temperature rich-solution supply line (12-1) that feeds the low-temperature rich solution (1007-1) to the low-temperature regenerator (1008-1), and a low-temperature lean-solution supply line (13-1) that feeds a low-temperature lean solution (1009-1) to the low-temperature absorber (1006-1) from the low-temperature regenerator (1008-1); and a high-temperature CO2 reducing apparatus (11-2) that is arranged on a side at which the flue gas (1002) is discharged, and that has the same configuration as the low-temperature CO2 reducing apparatus (11-1).
摘要:
A coal reforming apparatus includes: a dryer body provided to dry low-quality coal; a pyrolysis body which pyrolyzes the dried coal thus dried; and a briquetter which compression-molds the pyrolyzed coal thus pyrolyzed. The coal reforming apparatus has a radical scavenger supplier which supplies drying gas with a radical scavenger so that the low-quality coal can be dried in an atmosphere containing the radical scavenger, the drying gas being supplied from a drying gas supply source and heated by a heater, the radical scavenger being formed of an organic compound having a hydroxyl group.
摘要:
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.
摘要:
An absorbent liquid according to the present invention is an absorbent liquid for absorbing CO2 or H2S or both from gas, in which the absorbent liquid includes an alkanolamine as a first compound component, and a second component including a nitrogen-containing compound having in a molecule thereof two members or more selected from a primary nitrogen, a secondary nitrogen, and a tertiary nitrogen or a nitrogen-containing compound having in a molecule thereof all of primary, secondary, and tertiary nitrogens. The absorbent liquid has an excellent absorption capacity performance and an excellent absorption reaction heat performance, as compared to an aqueous solution containing solely an alkanolamine and a nitrogen-containing compound in the same concentration in terms of wt %, and can recover CO2 or H2S or both from gas with smaller energy.

摘要:
An absorbent according to the present invention absorbs CO2 or H2S contained in flue gas emitted from a power generating plant such as a thermal plant, and contains three or more amine compounds selected from linear or cyclic amine compounds having a primary amino group, and linear or cyclic amine compounds having a secondary amino group. By way of a synergetic effect of the mixture of these compounds, the absorption speed of CO2 or H2S absorption is improved. A small amount of CO2 contained in a large amount of boiler flue gas can be absorbed efficiently.
