This TSA Process Promises to Slash Costs for CO₂ Separation

Share This Post

A post-combustion process capable of separating CO2 from fluegas at one-third the cost of alternative separation processes has been developed by Svante Inc (Formerly Inventys Thermal Technologies, Inc.) (Burnaby, B.C., Canada;

Tradenamed VeloxoTherm (VX), the patented process is now being tested together with a consortium of industrial partners — Mast Carbon International, BP, Suncor Energy Services and Doosan Babcock Energy — in a $1.9-million project funded by Sustainable Development Technology Canada (SDTC; Ottawa).

VX is an intensified temperature-swing adsorption (TSA) process that features structured, proprietary adsorbers (photo) instead of beaded adsorbents used in conventional packed-bed TSA processes. As a result, VX delivers enhanced heat and mass transfer at significantly lower pressure drop, says Darryl Wolanski, vice president of business development at Svante.

“The adsorption kinetics of the VX process is very fast — on the order of minutes to complete an entire adsorption-regeneration cycle, explains Wolanski. And because the regeneration temperature is lower than that required by conventional amine-based…

Brett Henkel’s unabashed optimism tempered by his mechanical engineering background and gas separation experience combine to bring a rare perspective to his position on Svante’s executive team.

Transferring the company’s breakthrough CO2 capture technology to customers’ sites will rely heavily on Brett’s strengths for identifying and understanding the technical and business details and relating those details to partners’ teams, approving agencies, and stakeholders.

As co-founder, he was instrumental in creating the process and the hardware used to prove the technology’s effectiveness as well as mobilizing external support throughout the path to becoming a successful innovation. These experiences strengthened his knowledge of business development and program management priorities.

Prior to launching Svante, Mr. Henkel was the program manager for QuestAir Technologies’ compact hydrogen production system with its partner, ExxonMobil. He is credited with designing the world’s first solenoid-driven rapid pressure swing adsorption test station.

Brett received his Bachelor of Science in Physics, with distinction, and a Mechanical Engineering degree from the University of Victoria.
