Our solutions help you comply with the most stringent clean air standards, to help refining and shipping businesses worldwide grow their enterprise while reducing their environmental footprint.

Our professionals can assess, recommend, design, manufacture and deliver an “all-in-one” integrated particulate, sulfur oxide (SOx), and nitrogen oxide (NOx) reduction system to help meet your organization’s complete air emissions control needs. We can stay with you through start-up and continue helping you maintain peak efficiency throughout your system’s operation. Our extensive leadership, science and technology resources can enable your organization to expand into new markets, boost production of existing products, and increase profitability by utilizing lower-cost fuels — all while BELCO® systems keep your operations in compliance.

EDV® Wet Scrubbing Systems

Our proprietary EDV® wet gas scrubbing systems can help achieve very high levels of pollutant control for fine particulate matter and heavy metals, as well as SOx and NOx reduction.

LABSORB™ Regenerative SO₂ Reduction Systems

This proven regenerative SO₂ scrubbing technology has had multiple full-scale commercial installations on fluid catalytic cracking units (FCCUs) and sulfur recovery units (SRUs). LABSORB™ systems consist of a pre-scrubber, absorber, and regeneration unit.

LoTOx™ and SCR NOx Reduction Systems

We offer a variety of customizable solutions for NO₂ emissions reduction, based on either the Hitachi SCR (Selective Catalytic Reduction) or Linde’s LoTOx™ low-temperature oxidation technology.

Shell Global Solutions Third and Fourth Stage Separators (TSS/FSS)

The Shell Global Solutions TSS/FSS is used to accomplish very high reductions of catalyst fines emissions from FCCU flue gas. The TSS/FSS is applied at high temperatures and high pressures, and can be designed for Turbo Expander protection and/or environmental control. We provide these leading systems to the global refining industry for FCCU applications on a material supply basis.

Marine Scrubbing Systems

The BELCO® Marine Scrubber can help reduce air emissions from ship engines, boilers and heaters. It enables organizations to meet all IMO, SECA, and EPA regulations, without switching to low-sulfur fuel. We offer three different designs to meet a variety of requirements. Our Closed Loop Design features caustic scrubbing to minimize wash water discharge from the ship, as may be required in certain ports. Our Open Loop Design enables shippers to discharge wash water at sea while meeting all applicable IMO regulations. Lastly, our Hybrid Design gives shippers the flexibility to use either Closed Loop or Open Loop technology, as their circumstances and preferences merit.
