ExxonMobil scrubbing technology selected by Valero Energy
Posted: 10 October 2007
ExxonMobil Research and Engineering Company (EMRE) and Hamon Research-Cottrell (HRC) reported today that Valero Energy has selected ExxonMobil's Wet Gas Scrubbing Plus (WGS+) technology for its Memphis, Tennessee and Delaware City, Delaware refineries.
Project planning for both locations is underway.
At the Memphis refinery, the technology was selected as part of an overall emissions reduction project on the 60,000 barrel per day Fluid Catalytic Cracking Unit (FCCU).
Hamon Research Cottrell is engineering and supplying an expanded Wet Gas Scrubber (WGS) which significantly reduces sulfur and particulate emissions.
As part of this project, HRC is also supplying EMRE WGS+ technology to significantly reduce NOx emissions.
At the Delaware City Refinery, the WGS+ technology is being engineered and supplied for a 60,000 barrel per day FCCU which has an existing scrubber used for the removal of sulfur and particulate matter. Here, WGS+ technology will significantly reduce NOx emissions as well.
Wet Gas Scrubbing Plus technology, developed and commercialized by EMRE, is used to reduce oxides of nitrogen emissions from FCCUs. This technology can easily be retrofit on EMRE WGS units or other FCCU scrubbers.
Wet Gas Scrubbing has been retrofitted into full-burn and partial-burn FCCUs, even those with first generation CO boilers and/or those operating at very low flue gas pressure.
The technology can be designed to operate at the lowest pressure drop of any commercial scrubber technology and eliminates the need for expensive boiler modifications to be installed within an operating facility.
The Wet Gas Scrubbing technology (WGS and WGS+) requires a very small onsite plot space allowing for flexibility in location.
