Publication number: 20140131975Abstract: A trailer for transporting a liquid mixture having at least about 5% peracetic acid by weight includes a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure. One or more pressure relief valves are included in a wall of the tank within the external spill containment enclosure and configured to provide pressure relief to the tank at a pressure of between about 20%-50% of the maximum working pressure of the tank, thereby preventing over-pressurization of a reactive and decomposing fluid during a fire event. Wheels and a kingpin are affixed to the tank to enable transportation over public roadways.Type: ApplicationFiled: September 6, 2013Publication date: May 15, 2014Applicant: FMC CORPORATIONInventors: John M.
