In a continued effort to increase plant efficiencies, Husky hired IPS to install a system that would eliminate nearly all of the existing atmospherically vented butane through a series of pressure safety valves. The process protects butane storage spheres from overfilling and collects excess butane vapor and liquids.
In the first stage of this project, IPS installed a 10-in flare collection header to capture and route the vented butane. The gas that is collected is then transferred to a newly installed 17,000-gal heated KO drum to ensure vaporization.
Over 5,000 FT of new flare line was installed on nearly two hundred new 25-FT tall pipe supports in and around the Butane areas and along existing pipe racks. Approximately 80 existing atmospheric butane vents will ultimately be connected to the flare line, which will protect venting from the two butane spheres, five butane bullets, the coalescers, and the butane caverns.
Working within a refinery requires strict attention to detail and tight safety controls. IPS assigned an onsite safety manager to oversee all safety aspects and ensure proper procedures were followed when working with crane operations, rigging, and at various heights. Work was completed on time and with zero safety incidents.
