Abstract
Official abstract text for this publication.
One exemplary embodiment can be a process for purifying a disulfide oil. The process can include obtaining at least a portion of a disulfide oil coalesced from an alkaline stream, and passing the at least a portion of the disulfide oil through a mesh for recovering a purified disulfide oil stream.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process to produce a purified disulfide oil stream, comprising: A) passing a liquid phase alkaline solution comprising the disulfide oil through one or more coalescer elements in a base of a vessel to produce a coalesced alkaline solution; B) separating at least a portion of the disulfide oil from the coalesced alkaline solution in the base of the vessel; and C) passing the at least a portion of the disulfide oil through a mesh in a stack of the vessel for recovering a purified disulfide oil stream. 2. The process according to claim 1 , wherein the separating occurs in a separation portion of the base of the vessel and the disulfide oil and the alkaline solution form separate phases in the separation portion of the base of the vessel. 3. The process according to claim 1 , wherein the stack additionally contains a gas phase. 4. The process according to claim 3 , wherein the gas phase is at a pressure of about 200- about 600 kPa. 5. The process according to claim 2 , further comprising controlling a level of a phase interface between the disulfide oil and the alkaline solution in the separation portion of the base of the vessel using a level indicator controller. 6. The process according to claim 1 , wherein the one or more coalescer elements comprises at least one of a metal mesh, one or more glass fibers, a sand, or an anthracite coal. 7. The process according to claim 1 further comprising providing an effluent from an oxidation unit comprising a spent gas phase comprising air and disulfide vapors and the liquid phase alkaline solution to another stack of the vessel and separating the liquid phase alkaline solution from the spent gas phase.
