Abstract

Two inline tower gas wet scrubbers having a moving bed of solids for scrubbing exhaust gas Two inline tower gas wet scrubbers wherein each scrubber has a moving bed of solids 0010 that is conveyed from the top to the bottom of the towers via a plurality of perforated moving floors 003 arranged one above the other. Wherein the moving floors are mounted on plenums 004 that extend from the internal walls of the towers. A liquid 008 is sprayed from the top of each tower, wherein the liquid washes the exhaust gas, capturing particle matter and absorbing acidic gases and heat. As the liquid falls under gravity, the liquid is filtered through the solids. Exhaust gas e.g. containing CO2 enters the first scrubber 001 above the bottom plenum and travels upwards over the moving bed towards the outlet at the top of the scrubber, whilst being washed by the falling liquid. The warm carbonated solids and liquid that exit the first reactor are fed into the top of the second reactor 002, whilst the gas exiting the first reactor enters the second reactor via the plenums/ducts that support the moving floors thereby distributing the gas throughout the reactor.

Dependent claims

A continuous type process method in two reactors when operational comprise in the first reactor:

a. the solids conveyed into the top of the reactor form a moving bed on each of the plurality perforated moving floor mounted on a plenum and arranged one above the other;
b. the solids travel horizontally in a direction on the top most moving floor before it falls on to the following moving floor which moves the received solids horizontally in the direction opposite to the former;
c. this travel pattern of solids as in (b) is repeated in the following moving floors before solids exit the first reactor from the last moving floor;
d. the liquid droplets are sprayed from above evenly throughout the area of each moving bed of solids;
e. the gasses enter above the last moving bed of solids and flow counter current to the travel direction of the solids interfacing with the falling liquid droplets;
f. the droplets after the interface with the gasses fall evenly across the area of each moving bed of solids, filter through the bed by gravitational flow to the bottom of the moving bed and exit the first reactor;
g. the exiting gasses from the first reactor is distributed and enters every plenum in the second reactor;
h. the exiting solids from the first reactor is transferred and fed into the top moving perforated floor in the second reactor;
i. the solids and gasses exit the second reactor.
