Geothermal Power Generation

Geothermal power generation produces a sustainable source of energy by converting superheated fluids from the earth’s geothermal resources into electrical energy. The exhaust from a geothermal power plant contains sulfur compounds, the majority of which is hydrogen sulfide (H₂S). This gas stream is the passed through a regenerative thermal oxidizer (RTO) to oxidize the sulfur compounds to sulfur dioxide (SO₂). Envitech’s packed bed scrubber removes the SO₂ before the exhaust stream is vented to the atmosphere.

Many geothermal facilities are located in desert climates where temperatures exceed 105^oF in the summer. Envitech’s SO₂ scrubbers are designed to operate in this extreme climatic condition. Envitech has installations at both Cal Energy and ORMAT near the Salton Sea in El Centro, CA.
