LoTOx™ Process for NOx Control with BELCO^® Wet Scrubbing

The BELCO^® multi-pollutant control solution offers NOx, SOx and particulate emissions removal in a single upflow BELCO^® scrubber with integrated LoTOx™ process. This wet scrubbing based NOx reduction technology provides greater than 95% NOx reduction without the limitations or process and mechanical problems common to most Selective Catalytic Reduction (SCR) systems. As a result, refiners can achieve NOx, SOx and particulates emission targets at a lower cost, with higher reliability on less space and with greater flexibility than ever before. With extensive industry experience working on a wide range of different fuel types, we are familiar with the issues they present and can adapt the LoTOx™  NOx control technology to suit your needs and ensure your plant meets its clean air targets.

The LoTOx™ process is applied as part of a BELCO^® wet scrubbing system, allowing for a truly integrated, multi-pollutant reduction solution. NOx compounds are oxidized at a low temperature using ozone and converted to soluble compounds that are easily removed from the flue gas by the same liquid-gas contact that removes particulate and SOx. This process is well suited to the demanding requirements of FCCU applications. The unique BELCO^® spray tower design and specialized spray nozzles provide the right conditions for the effective use of the LoTOx™ process. A droplet-free zone and open tower design provide high reduction efficiency without the risk of plugging. The entire system is engineered to ensure trouble-free handling of process upsets, long operating campaigns, temperature excursions, boiler bypass and pollutant inlet loading fluctuations.
