Processes and systems for oxygen-enhanced Claus carbon dioxide recovery are disclosed. Oxygen is fed to a sulfur recovery unit instead of air. The tail gas is fed to a tail gas treatment unit which produces a treated tail gas, and the treated tail gas is processed in a carbon dioxide recovery unit to produce a carbon dioxide product. A method for retrofitting an existing sulfur recovery unit and tail gas treatment unit so as to recover the carbon dioxide product is also disclosed.

Oxygen-enhanced Claus carbon dioxide recovery

A method of diverting municipal solid waste (MSW) from a landfill that includes receiving, at a MSW processing system, a quantity of MSW, gasifying the quantity of MSW in a gasification unit to yield a syngas stream and biochar stream, converting at least a portion of the syngas to mixed alcohols in an alcohol synthesis unit, separating the mixed alcohols into one or more alcohol products, and determining a carbon offset for diverting the MSW from the landfill to the MSW processing system.

Methods and system for decreasing gas emissions from landfills

Systems and methods for generating higher alcohols from synthesis gas produced from carbonaceous materials are described, which can include a reactor configured to produce an alcohol stream and COfrom a syngas feed. The alcohol stream can be separated in one or more downstream separators to produce a net reactor product and a methanol stream that can recycled into the reactor. The net reactor product preferably comprises higher-order alcohols such as ethanol, propanol, and butanol.
