✦ Synopsis
STATES assigned to Cyanotech Corporation
An integrated plant including a microalgae production plant for growing, harvesting and drying algae and a fossil fuel-motor-generator plant producing electrical energy. A fossil fuel engine produces hot exhaust gas from which sensible heat dries the algae. The drying may be direct from the exhaust gas or may be indirect with the hot exhaust gas exchanging sensible heat with a recirculating stream of inert gas. Carbon dioxide from the exhaust gas is recovered for use as a nutrient in the microalgae production plant. Electrical energy from the generator is used to drive motors and/or produce artificial illumination and/or drive pumps, motors and controls in the microalgae production plant.
