Advanced membrane oxidation process and system for the treatment of industrial gas emissions and odors

A system for treating a gaseous material, comprising:

• a reactor;
• at least one porous ceramic membrane placed into the reactor;
• and an ozone (O3) distributor adapted to feeding O3 into the reactor;
• optionally the system comprises a hydrogen peroxide (H2O2) distributor adapted to feeding H2O2 to the at least one membrane;
• optionally the system comprises a liquid sorbent material distributor adapted to feeding the liquid sorbent material to the at least one membrane;
• optionally the system comprises an ultraviolet (UV) radiation system adapted to submitting radiation to the at least one membrane;
• preferably the O3 distributor comprises means for controlling an amount of O3 fed into the reactor;
• preferably the O3 distributor receives O3 from an ozone (O3) generator adapted to generate O3 from oxygen;
• preferably the system is a closed-loop system;
• preferably the system is adapted for integration into existing industrial installations without requiring significant modifications to the infrastructure.

A method for preparing a liquid nano-sorbent, comprising:

• a first step based on a top-down approach and a second step based on a membrane nanofiltration technology, optionally, prior to conducting the first and second steps of the method, raw materials are subjected to ultrafine mechanical grinding followed by mechanical sieving to obtain sieved particles;
• optionally the first step of the method comprises forming a suspension comprising the sieved particles and a dispersing agent, and subjecting the suspension to mechanical grinding;
• optionally the second step of the method comprises subjecting the grinded suspension to a membrane nanofiltration wherein a permeate is recovered, and a retentate with larger size particles is removed or recycled;
• optionally the method further comprises subjecting the permeate to a nanofiltration process comprising use of a stabilizer.
