System and method for containing an emission of sulfur trioxide

A system for containing an emission of sulfur trioxide, the system comprising:

• a first pressurized vessel, the first pressurized vessel containing sulfur trioxide and wherein the first pressurized vessel is a storage vessel;
• a relief vessel containing a volume of a solvent solution, wherein the solvent solution comprises sulfolane;
• a first relief conduit providing a first route of fluid communication between the first pressurized vessel and the relief vessel;
• a second pressurized vessel, wherein the second pressurized vessel is a reactor and wherein the reactor contains a reaction mixture;
• a second relief conduit providing a second route of fluid communication between the second pressurized vessel and the relief vessel;
• a separation unit;
• and
• a third relief conduit providing a third route of fluid communication between the separation unit and the relief vessel,
• wherein an effluent stream conveyed from the reactor is separated into an output conduit and a product conduit by the separation unit, the output conduit comprising the third relief conduit.
