Ener-Core and Siemens’ Dresser Rand this week announced the latest milestone in the development of Ener-Core’s Power Oxidizer technology.
The firms said they have now achieved mechanical completion and initial startup of a 2 MW PowerStation, which integrates Dresser-Rand’s KG2 gas turbine with the Power Oxidizer, at Pacific Ethanol’s Stockton Biorefinery facility in the US state of California.
The PowerStation ‘operated successfully and demonstrated the ability to produce both power and steam according to specifications,’ the companies said. Commissioning is planned for the first quarter of this year.
The two-unit PowerStation is rated to provide up to 3.5 MWe and over 26,000 pounds of steam per hour. It is planned to convert low-quality waste gases that are by-products of the ethanol production process into power and steam for Pacific Ethanol’s Stockton facility.
The new system is expected to save the plant an estimated $3-4 million per year in energy expenditure, Ener-Core said.
