Abstract
A system for the production of synthesis gas and, for the production thereof, where the system is preferably a net carbon dioxide absorber. The invention covers both the methodology for the development of the process and the system for the implementation of the process, inclusive of the required utility systems.
Claims4
A method for the production of synthesis gas, wherein the method comprises the steps of:
- feeding reactants into a reformation process, wherein the reformation process comprises the steps of:
- a phase change of liquid water to gaseous water;
- a combustion of a first hydrocarbon gas to produce carbon dioxide and gaseous water;
- and
- steam reformation of a second hydrocarbon gas, wherein the second hydrocarbon gas is mixed together with the carbon dioxide and gaseous water from the combustion step;
- transferring heat, and product resulting from the reformation process to a Reverse Water Gas Shift (RWGS) reactor to complete a RWGS reaction to produce the synthesis gas, gaseous water and carbon dioxide by-product;
- returning the carbon dioxide to the RWGS reactor for further reaction;
- and
- returning the gaseous water to the reformation process.
