Patent ID: 8852540

Claim:
An apparatus for removing sulfur dioxide from a flue gas, the apparatus comprising: a housing defining a scrubbing chamber and a regeneration chamber separated from the scrubbing chamber by a separating wall having an open region to provide a hydraulic communication between the scrubbing chamber through a pool common for the scrubbing chamber and the regeneration chamber and comprising a molten eutectic mixture of lithium, sodium and potassium carbonates; the scrubbing chamber comprising: a flue gas inlet port configured for receiving an ingress flow of said flue gas, and a scrubbed gas outlet port configured for discharging an egress flow of a scrubbed gas from the scrubbing chamber; the scrubbing chamber being configured for scrubbing the flue gas by absorbing the sulfur dioxide in the pool to form a molten mixture of carbonates, sulfites and sulfates in the pool; the regeneration chamber being configured for producing a sulfur-containing vapor; and comprising a sulfur-containing vapor outlet port configured for controllable release of the sulfur-containing vapor obtained therein; and a sulfur-containing material collector coupled to said sulfur-containing vapor outlet port via a cooling manifold configured for cooling down said sulfur-containing vapor, and thereby converting said sulfur-containing vapor into a liquid and solid phase materials.
