Power
Increasing world power demand coupled with a global trend towards strict emissions regulations has resulted in an increased demand for flue gas desulfurization technologies.
Public electricity and heat production are two of the largest sources of SO2 emissions, with coal-burning power plants being the primary contributors. Legislation has therefore sought to impose emissions restrictions at national level. However, as power and coal gasification plants produce process off-gas with variable concentrations of sulfur dioxide, companies face a number of constraints when seeking out a solution to control potential emissions. MECS®’s SolvR® and SULFOX™ technologies provide flexible solutions to treat SO2-bearing off-gas in both power and coal gasification plants. For smaller power plants (<300MW) that require high SO2 removal efficiencies, the unique features of the DynaWave® reverse jet scrubber technology with its extremely high on-stream reliability and outstanding ease of operation offer an excellent solution.
MECS® SULFOX™ wet sulfuric acid plant technology treats the SO2-bearing off-gases, leaving a wet gas cleaning plant using a wet catalytic process that recovers sulfur-containing compounds as commercial-grade concentrated sulfuric acid (96-96%). It is suitable for applications in the power and coal gasification industries where waste gas contains H2S and/or CS2 and/or SO2 and must be desulfurized.
Each SULFOX™ plant is custom-designed according to feed gas concentration and individual site specifications and is tailored to keep capital expenditure and operation costs as low as possible. The SULFOX™ process has over 20 years of successful field experience.
This technology has been used successfully around the world. The benefits for power and coal gasification plants that treat process off-gases with this method include:
Elessent Clean Technologies is one of the few companies to design and manufacture its own sulfuric acid process equipment and technologies including catalysts, heat recovery and mist elimination equipment. By combining process technology expertise, materials science and nearly a century of sulfuric acid plant experience, we provide a single point of contact for advanced, proven technology, performance and service.
