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.

1. A method for separating liquid sulfur from tail gasses using a sulfur sealing apparatus, the method comprising: receiving a liquid sulfur and gas mixture in a first chamber of the sulfur sealing apparatus, wherein the liquid sulfur and gas mixture comprises a liquid sulfur portion and a tail gas portion;separating the liquid sulfur and gas mixture during normal operation into the liquid sulfur portion and the tail gas portion by allowing flow of the liquid sulfur portion from the first chamber into a second chamber of the sulfur sealing apparatus while preventing the tail gas portion from flowing from the first chamber into the second chamber of the sulfur sealing apparatus; wherein the first chamber is operatively coupled to the second chamber of the sulfur sealing apparatus through the use of a divider and a seal,wherein the first chamber comprises a float that is operatively coupled to the seal for sealing and unsealing the first chamber from the second chamber andwherein the liquid sulfur portion of the liquid sulfur and gas mixture flows from the first chamber into the second chamber of the sulfur sealing apparatus when the float in the first chamber opens the seal, and the tail gas portion of the liquid sulfur and gas mixture is prevented from flowing from the first chamber into the second chamber of the sulfur sealing apparatus; andunsealing the seal or a second seal between the first chamber and the second chamber during an over-pressurization event by allowing both the liquid sulfur portion and the tail gas portion to flow from the first chamber into the second chamber to allow for pressure relief. 2. The method of claim 1, wherein the second chamber of the sulfur sealing apparatus is located at least partially above the first chamber and the flow of the liquid sulfur from the first chamber to the second chamber is at least partially upwards. 3. The method of claim 2, wherein the sulfur sealing apparatus further comprises: an outlet channel operatively coupled to the divider and extending into the first chamber;wherein the outlet channel is at least partially submerged within the liquid sulfur;wherein a liquid sulfur level within the outlet channel is above a liquid sulfur level within the first chamber; andwherein the liquid sulfur flows from the outlet channel in the first chamber into the second chamber when the float unseals the seal between the first chamber and the second chamber. 4. The method of claim 1, wherein the second chamber is located at least partially adjacent the first chamber and the flow of the liquid sulfur from the first chamber to the second chamber is at least partially horizontal. 5. The method of claim 1, wherein the second chamber is located at least partially below the first chamber and the flow of the liquid sulfur from the first chamber to the second chamber is at least partially downward. 6. The method of claim 1, wherein the second chamber is located at least partially within the first chamber, or wherein the first chamber is located at least partially within the second chamber. 7. The method of claim 1, wherein the unsealing occurs through the use of the seal. 8. The method of claim 1, wherein the seal comprises: a plug operatively coupled to the float; anda seal seat having an orifice, wherein the seal seat is operatively coupled to the divider; andwherein the seal is sealed when the plug seals with the seal seat; andwherein the seal is unsealed when the plug is unsealed with the seal seat. 9. The method of claim 8, wherein the plug is located at least partially in the second chamber of the sealing apparatus. 10. The method of claim 8, wherein the plug is located at least partially in the first chamber of the sealing apparatus. 11. The method of claim 1, wherein the unsealing occurs through the use of the second seal. 12. A method for separating liquid sulfur from tail gasses using a sulfur sealing apparatus, the method comprising: receiving a liquid sulfur and gas mixture in a first chamber of the sulfur sealing apparatus, wherein the liquid sulfur and gas mixture comprises a liquid sulfur portion and a tail gas portion;separating the liquid sulfur and gas mixture during normal operation into the liquid sulfur portion and the tail gas portion by allowing flow of the liquid sulfur portion from the first chamber into a second chamber of the sulfur sealing apparatus while preventing the tail gas portion from flowing from the first chamber into the second chamber of the sulfur sealing apparatus;wherein the first chamber is operatively coupled to the second chamber of the sulfur sealing apparatus through the use of a divider and a seal, and wherein the seal comprises a plug located at least partially in the second chamber;wherein the first chamber comprises a float that is operatively coupled to the seal for sealing and unsealing the first chamber from the second chamber; andwherein the liquid sulfur portion of the liquid sulfur and gas mixture flows from the first chamber into the second chamber of the sulfur sealing apparatus when the float in the first chamber opens the seal by moving the plug further into the second chamber, and the tail gas portion of the liquid sulfur and gas mixture is prevented from flowing from the first chamber into the second chamber of the sulfur sealing apparatus. 13. The method of claim 12, wherein the second chamber of the sulfur sealing apparatus is located at least partially above the first chamber and the flow of the liquid sulfur from the first chamber to the second chamber is at least partially upwards. 14. The method of claim 13, wherein the sulfur sealing apparatus further comprises: an outlet channel operatively coupled to the divider and extending into the first chamber;wherein the outlet channel is at least partially submerged within the liquid sulfur;wherein a liquid sulfur level within the outlet channel is above a liquid sulfur level within the first chamber; andwherein the liquid sulfur flows from the outlet channel in the first chamber into the second chamber when the float unseals the seal between the first chamber and the second chamber. 15.
