A ModuleAir air-cooled condenser (ACC) developed and manufactured by SPX Cooling Technologies Inc., Overland Park, Kan., will provide process cooling of exhaust steam as part of the power generation operation at the Red Leaf Resources Inc. (Red Leaf) shale oil extraction process plant in Seep Ridge, Utah. Natural gas produced at the site will power two boilers serving a 7 MW steam turbine generator. The ModuleAir ACC will condense exhaust steam from the steam turbine and return condensate to the boilers through the use of dry cooling, thus eliminating water usage from the cooling process. The plant is expected to be operational in late 2015.
The modular design of the ModuleAir ACC provides factory-assembled structural components, duct and heat exchanger bundles to shorten construction duration and reduce construction costs. Advantages of its design include improved performance during low ambient conditions and enhanced annual average power plant output.
The Red Leaf Seep Ridge plant will utilize the EcoShale In-Capsule process developed and patented by Red Leaf, South Jordan, Utah. The process involves heating mined shale in a closed-surface impoundment or capsule to produce feedstock. The production of high hydrogen content natural gas is a by-product of the extraction process.
The use of this produced gas for power generation represents a captured value that would otherwise be lost potential in the shale-oil extraction process.
