Abstract

See full text

Embodiments of the invention are directed to a sulfur trap comprising an inlet, a first chamber, a divider, a second chamber, an outlet, and a float assembly. The float assembly may have many different configurations, but generally comprises a float and plug, is configured to float within liquid sulfur, and is operatively coupled to a seal seat in the divider for sealing and unsealing the first chamber from the second chamber. Generally, only liquid sulfur is allowed to pass from the first chamber into the second chamber. However, the sulfur trap may be configured to allow for pressure relief, such that during an overpressure event the plug and seal seat disengage and allow the liquid-gas mixture to flow into the second chamber to prevent damage within the system. In some embodiments a filter and/or the flow of liquid sulfur is directed to collect debris from the liquid sulfur.
