EDV wet scrubbing systems reduction of particulates SO2, SO3, and NOX

EDV® Wet Scrubbing operates on the principles of saturation, absorption, condensation, and filtration. Specialized vessels and spray nozzles are used to control a variety of pollutants with system configured for each application’s requirements. Longer operating campaigns and little regulatory tolerance for emissions excursions mean today’s petroleum refining processes demand more than traditional emission control technologies can deliver. The DuPont™ BELCO® Technologies EDV® Wet Scrubbing technologies bring well proven refinery performance to every application. In widespread use for controlling FCCU emissions during multiple year operating campaigns, EDV® Wet Scrubbing systems operate without outage requirements or emission excursions. EDV® Wet Scrubbing systems are in use worldwide controlling flue gas emissions from FCCUs, refinery incinerators, fired heaters, boilers, and other industrial applications.

Wet Scrubbing uses liquid contact with flue gas to remove acid gases, particulate and other pollutants. Proprietary technologies and the level of performance achieved set EDV® Wet Scrubbing apart from any competition. Traditional wet scrubbing processes generate fine mist as the liquid-to-gas contact needed for efficient collection performance. It is this mist generation and collection that creates major reliability problems with traditional wet scrubbers. High efficiency mist eliminators must be used to collect mist containing captured pollutants. Solids and salts quickly build-up on mist eliminator surfaces, leading to plugging and maintenance problems. FCCU process upsets are particularly difficult to handle. Not so when using EDV® Technology.

EDV® Wet Scrubbing avoids any mist formation, meaning no mist eliminator problems. Proprietary spray nozzles and low gas pressure drop vessels use size-controlled liquid droplets for effective gas contact. Simple cyclonic separation easily removes any excess water from the gas. Vessels, nozzles and droplet separators are open and extremely durable, supporting continuous operation for multiple years without outages for service work. EDV® Wet Scrubbing provides what traditional wet scrubbers on FCCU and other refinery applications just cannot deliver.
