Jeffrey P. Newton, Founder & President of ASG, built a pilot plant built in 2006-2007 in Lloydminister, Alberta, primarily for the commercial upgrading of heavy oils by hydrogenation. This upgrading technology was a precursor to the G-44 Process.
The upgrading pilot plant had a capability to process 2,000 bbl./day of emulsion. CO2 was added to these heavy oil streams to mimic some production fluids in the area. The reduction in the CO2 in various pilot runs was from 85% to 95%.
As an experiment to run CO2 in a water stream, 430 cubic meters of CO2, water, and chemistry were added during one pilot test run that continued for over 14 hours. There was a drop in temperature of approximately 13°C in a water flow containing chemistry and CO2. The flow of water was 35 liters per minute with energy consumption at about 20 kilocal/mole of CO2. This was an endothermic reaction with no or little additional hydrocarbon presence.
Although this pilot plant was principally designed to upgrade heavy oil, the flow of gas into this pilot plant system was more than 10 times the rate of the portable G-44 Process pilot system. The conversion rate was approximately 87% in a single pass.
