System and Method for Containing an Emission of Sulfur Trioxide
First Claim
1. A system for containing an emission of sulfur trioxide, the system comprising:
- a first pressurized vessel, the first pressurized vessel containing sulfur trioxide;
a relief vessel containing a volume of a solvent solution, wherein the solvent solution comprises sulfolane; and
a first relief conduit providing a first route of fluid communication between the first pressurized vessel and the relief vessel.

Abstract
A system for containing an emission of sulfur trioxide, the system comprising a first pressurized vessel, the first pressurized vessel containing sulfur trioxide, a relief vessel containing a volume of a solvent solution, wherein the solvent solution comprises sulfolane, and a first relief conduit providing a first route of fluid communication between the first pressurized vessel and the relief vessel. A method for containing an emission of sulfur trioxide, the method comprising routing a first relief conduit so as to provide a first route of fluid communication between a first pressurized vessel and a relief vessel, wherein the first pressurized vessel contains sulfur trioxide, wherein the relief vessel contains a volume of a solvent solution, and wherein the solvent solution comprises sulfolane.

16. A system for containing an emission of sulfur trioxide, the system comprising:
-
a relief vessel comprising a solvent solution; and an input conduit in fluid communication with at least one of a first pressurized vessel, a second pressurized vessel, and an output conduit, wherein the input conduit conveys sulfur trioxide to the relief vessel, forming an emission mixture when the sulfur trioxide contacts the solvent solution. - View Dependent Claims (17, 18, 19)

20. A system for containing an emission of sulfur trioxide, the system comprising:
-
a relief vessel comprising a solvent solution; an input conduit in fluid communication with at least one of a first pressurized vessel, a second pressurized vessel, and an output conduit, wherein the input conduit conveys sulfur trioxide to the relief vessel, forming an emission mixture when the sulfur trioxide contacts the solvent solution; and a solvent regeneration system configured to; receive an emission mixture conduit conveyed from the relief vessel, add water to the emission mixture to facilitate a reaction with sulfur trioxide dissolved therein and to form sulfuric acid, regenerate sulfolane via at least one of a distillation, a back-extraction, adsorption, or counter-ion exchange column; and recycle regenerated sulfolane back to the relief vessel via a regenerated solvent solution conduit.
