US 12,121,851 B1 · Wellhead carbon capture, utilization, and storage using mixed matrix membranes

Abstract

A system for carbon dioxide (CO2) capture at a wellhead using a mixed matrix membranes (MMM). The MMM includes a polymer matrix and covalent triazine framework (CTF) fillers. The captured CO2 stream may be reutilized through sequestration and utilization approaches. The bulk stream may be split into multiple streams for various applications. Some CO2 may be converted chemically into fuels, reaction intermediates, and productivity enhancement tools such as methanol, syngas, CO2-foam, used in fracking fluids, and stimulant acids. The rest may be stored through direct injection into porous formations or reactive rocks such as basalt.

Dependent claims

A carbon dioxide (CO2) separation system, comprising:

a mixed matrix membrane (MMM) installed at a wellhead of a wellbore formed in a subterranean zone, the MMM configured to receive a gas stream comprising CO2 and a mixture of hydrocarbons through the wellbore, the gas stream being produced in the subterranean zone, wherein the MMM separates the CO2 from the mixture of hydrocarbons, wherein the MMM comprises a polymer matrix and a covalent triazine frameworks (CTF) filler;
and
a splitter installed downstream of the CO2 separation system to split the separated CO2 into a plurality of CO2 streams.
