Method for separation of carbon dioxide from flue gas flow emerging in fossil fired power plant by absorption medium in absorber unit, involves dividing absorption medium charged with carbon dioxide into two partial flows

Abstract: The method involves dividing an absorption medium charged with carbon dioxide into two partial flows after escaping from the absorber unit (1). The former partial flow and the latter partial flow are supplied to a desorber unit (2) and are supplied to different areas that are connected in series in flow direction of a carbon dioxide content gas stream separated from the charged absorption medium. The former partial flow of a desorption column is supplied to the desorption unit. The latter partial flow is supplied to a spray tower (11) of the desorption unit. An independent claim is included for a device for the separation of carbon dioxide from a flue gas flow emerging in a fossil fired power plant by an absorption medium in an absorber unit.

Spray liquid circulating device

Abstract: The invention discloses a spray liquid circulating device and relates to the field of energy conservation and emission reduction. The spray liquid circulating device comprises a box body and a top plate, wherein a bottom plate is arranged on a base of the box body; a reinforcing rib I is arranged on the bottom plate; a reinforcing ring II is arranged on the periphery of the box body; a pump interface is arranged on the box body; and a liquid supplement opening, an exhaust opening and a liquid return opening are formed in the top plate. The spray liquid circulating device disclosed by the invention is matched with a spray tower, spray liquid is contained in the box body, a spray head of the spray tower is connected with the pump interface on the box body through a pump body, and a liquid storage tank in the spray tower is connected with the liquid return opening of the top plate through the pump body and a pipeline, so that the liquid circulating and recycling of the spray liquid can be achieved. Through cyclic utilization of the circulating device, the energy is saved, the spray efficiency is improved, and the spray cost is reduced.

Waste gas treatment process

Abstract: The invention relates to a waste gas treatment process, which comprises the following steps: waste gas is pretreated, and the pretreated gas is injected into a first alkaline spray tower to undergo spraying; the gas treated by the first alkaline spray tower is injected into a scrubbing tank, so that first scrubbed gas is obtained; the first scrubbed gas undergoes catalytic reaction by means of a photooxygen catalysis chamber; the gas treated by the photooxygen catalysis chamber is sequentially treated by a second alkaline spray tower and a pool, so that second scrubbed gas is obtained; and after passing through a filter, the second scrubbed gas is discharged out. The purification effect of the waste gas treatment process disclosed by the invention is good, and the cost is low.

Treatment of specific gaseous material

Abstract: PURPOSE:To surely absorb and to remove phosphine, arsine or diborane by passing a gaseous specific material into any soln. of a mixed soln. of FeCl3, NaClO and HCl, chlorine water, ClO2 water, a bleaching powder soln. or iodine water. CONSTITUTION:A gaseous specific material contg. phosphine, arsine or diborane which is fed from a gas cylinder 1 and discharged from a semiconductor manufacturing factory or the like is brought into counterflow-contact with absorbing liquid in a spray tower and furthermore passed through a packed tower 3 packed with Rasching rings and discharged to the outside as clear gas via an adsorption tower 4. In this case, any one of a mixed soln. of FeCl3, NaClO and HCl, chlorine water, ClO2 water, a bleaching powder soln. and iodine water is used as the absorbing liquid. Phophine, arsine or diborane contained in the gaseous specific material is absorbed in the absorbing liquid and completely removed.
