Abstract
Apparatuses, systems, and methods related to removing carbon dioxide from a gas stream are provided. Gas streams can be waste gas streams or natural gas streams. The systems and methods for removing carbon dioxide incorporate water repurposing schemes. Still others are disclosed.
Claims22
A method of effectively reducing an amount of carbon dioxide from a gas stream comprising the steps of
- (a) generating an aqueous hydroxide solution in a chloro-alkali cell;
- (b) diluting the aqueous hydroxide solution to obtain a 5% to 15% by weight aqueous hydroxide solution;
- (c) admixing the diluted aqueous hydroxide solution with a first portion of a gas stream containing carbon dioxide to produce carbonate in a first admixture;
- and
- (d) removing water from the first admixture in a water removal unit;
- (e) after step (d), admixing the first admixture with a second portion of the gas stream to produce bicarbonate in a second admixture.

A system for effectively reducing carbon dioxide from a gas stream comprising:
- a gaseous stream comprising a carbon oxide;
- a first set of mixing equipment adapted to admix an aqueous hydroxide solution with a first portion of the gas stream to create a first admixture in which carbon oxide in the gas stream can react with the hydroxide to produce a carbonate product in a first liquid outflow;
- a water removal equipment adapted to remove a portion of the water from the first liquid outflow to yield a concentrated liquid outflow;
- a second set of mixing equipment adapted to admix the concentrated liquid outflow with a second portion of the gas stream to create a second admixture in which carbon oxide in the gas stream can react with the carbonate to produce bicarbonate products.
