Purifying caustic fluid including sulfur
The granted patent (Publication Number: US11905473B2) discloses a system for purifying a caustic fluid containing sulfur. The system includes a mixing assembly with inlet and outlet ports, conduits for the caustic fluid and hydrocarbon solvent, a prefilter assembly with porous elements, and a liquid-liquid coalescer assembly with filter elements for separating sulfur and hydrocarbon solvent from the caustic fluid. The system aims to reduce the sulfur content in the purified caustic fluid.
Furthermore, the system described in the patent operates within a pressure range of 50 psig to 600 psig. It also includes multiple porous prefilter elements and liquid-liquid coalescer filter elements in their respective assemblies to enhance the purification process. Additionally, a collection sump is integrated into the system to gather coalesced droplets comprising sulfur and hydrocarbon solvent. Overall, the system provides an efficient method for purifying caustic fluid by reducing sulfur content through a series of filtration and separation processes.
