Trailer and method for transporting peracetic acid

Abstract

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.

What is claimed is: 
     
         1 . A method for transporting a liquid mixture having at least about 5% peracetic acid by weight, the method comprising:
 filling a trailer with peracetic acid, the trailer comprising:
 a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure; and 
 one or more pressure relief valves included in a wall of the tank within the external spill enclosure, wherein the one or more pressure relief valves are configured to provide pressure relief to the tank at a pressure of less than about 50% of the maximum working pressure of the tank; and 
 transporting the trailer over a roadway using wheels and a kingpin affixed to the tank. 
   
     
     
         2 . The method of  claim 1 , wherein the maximum allowable working pressure is about 40 psig. 
     
     
         3 . The method of  claim 1 , wherein the one or more pressure relief valves are configured to provide pressure relief when a pressure inside the tank exceeds about 10 psig. 
     
     
         4 . The method of  claim 3 , wherein the one or more pressure relief valves have combined relief area greater or equal to 11.94 in 2 . 
     
     
         5 . The method of  claim 1 , wherein a relief area of the one or more pressure relief valves are configured to prevent internal pressure within the tank from exceeding a maximum pressure during a decomposition event or fire engulfment. 
     
     
         6 . The method of  claim 1 , wherein the one or more pressure relief valves includes two 4″ diameter pressure relief valves, each configured to provide pressure relief to the tank at about 10 psig. 
     
     
         7 . The method of  claim 1 , wherein the one or more pressure relief valves are reclosing pressure relief valves.
