Producing premium-quality extracts at competitive prices requires an unwavering commitment to innovation. For Christina Lake Cannabis Corp. (CLC), an early customer of Vitalis, growth eventually created bottlenecks, prompting the need for innovative solutions that would significantly improve throughput.

As the first adopter of the Cosolvent Injection System (CIS), CLC collaborated with Vitalis to achieve game-changing results through the controlled addition of small amounts of ethanol to their R-200 system’s CO2 stream.

Mark Aiken, CEO of CLC, said, “Originally using the R-200 extraction system, we were running mono-solvent CO2, impressed with the machine’s reliability and output. But since adding the Cosolvent Injection System (CIS) and other novel upgrades, we’ve seen massive improvements in our throughput and crude oil quality.”

    Before: high-viscosity crude oil from supercritical CO2-only extraction process

  • 7 test tubes with liquid substance, each a darker shade of golden orange, with the last one a dark brown

    After: low-viscosity crude oil samples from subcritical CO2 plus ethanol cosolvent extraction process

Highlights

  • Daily throughput increase of 300% since adding the CIS, enabling CLC to process at least 100,000 kg of biomass each year.

  • Faster extraction times (from 8-10 hours down to 30-90 minutes).

  • Major improvements in crude oil quality, making post-extraction processing faster and easier.

  • Cold subcritical CO2 extraction for minimizing fats and waxes.

  • Expanded selectivity to target polar or non-polar compounds for a greater variety of end products.
