In the United States (US), waste heat to power (WHP) technology provider and BITZER Group company ElectraTherm Inc., has partnered with privately held industrial process heat specialists Sigma Thermal to offer a waste gas-to-power packaged solution. Called the Emission Reduction and Power System, it consists of Sigma Thermal’s process heater and ElectraTherm’s Organic Rankine Cycle (ORC) generator and geared towards oil and gas facilities, wastewater treatment plants (WWTPs), and landfills.
According to a joint statement, the partnership has produced an integrated waste gas-to-power solution that can dramatically lower onsite emissions from flaring and produce electricity from a resource, otherwise considered “a nuisance.”
Within the integrated package, Sigma Thermal’s process heating system is being utilized to convert waste gas to hot water, which provides the energy needed to power ElectraTherm’s Power + Generator. Options are available that allow for a supply of hot water discharge that can be used on-site, and a hinged end-plate is included on the heater to provide easy access for dirty fuel cleaning.
The system is easy to transport, install and operate while meeting tough emissions requirements, local codes and producing power from an unutilized resource. The entire skid-mounted system is delivered with interconnecting piping and wiring and is ready for quick and easy on-site installation.
In oil and gas production and refining facilities where natural gas is being flared, the system can be used to convert waste fuel to electricity, minimizing and potentially eliminating flaring and significantly reducing emissions.
At wastewater treatment plants (WWTPs) and landfills producing biogas and landfill gas (LFG), the emission reduction system allows for easier management compared to conventional generators of gases containing hydrogen sulfide or siloxane contaminants and can contribute to the sites renewable energy goals.
