Flue Gas Scrubber Upgrade

An oil and gas company installed a steam generation plant with a flue gas scrubber and wet electrostatic precipitator (WESP). The intent was to use the field casing gas resource while mitigating high concentrations of hydrogen sulfide gas in the production stream.

Cannon had originally provided preliminary engineering for a thermal oxidizer; however, flue gas treatment was later selected over a thermal oxidizer or waste gas scrubber because these treatments had potential to interfere with development of the reservoir. The final project included two new steam generators, a two-stage flue gas scrubber, a WESP, and a new load center and motor control center enclosure.

Cannon brought diverse expertise in civil engineering, automation engineering, panel fabrication, programming, and automation integration services to the project. The implementation phase was challenging because the existing steam plant needed to be kept online during construction, requiring an interim control panel to manage a multi-phased build-out of the plant. During this process, Cannon implemented one temporary control panel, a nine-foot primary control panel, two fiber switch panels, two fiber termination units, and two flue gas diverter valve relay boxes.
