DEGASSING SYSTEM AND DEVICE FOR DEGASSING LIQUID SULFUR

摘要

Embodiments of the invention are directed to a sulfur recovery system that utilizes a degassing system for degassing liquid sulfur. The degassing system includes a degassing device vessel, a pressure equalizer, a motive force device, a sulfur cooler, and/or a process gas cooler. The degassing system may be located within or outside of the sulfur recovery unit and utilizes the process gas from the sulfur recovery unit. The degassing device may receive liquid sulfur and process gas, which are passed through a catalyst, which along with the process gas, degases the liquid sulfur. As such, the degassing system when used within the sulfur recovery unit degasses the liquid sulfur to reduce off-gassing of dangerous hydrogen sulfide during storage and transportation without the need for additional equipment to degas the liquid sulfur during or after the sulfur storage.
