SxSeal® 1000 Sulfur Trap

SxSeal® 1000

Above-ground Sulfur Seal Solution for SRU Rundown Lines

For many years, refineries and gas plants have employed below-ground seal legs to prevent process vapor from entering the sulfur pit or collection vessel. While seal legs perform this function well, they are prone to water intrusion and mechanical plugging, which results in costly repairs and unplanned SRU downtime. To address issues with current technology, CSI has partnered with oil and gas industry leaders to develop an above-ground sulfur seal solution: the SxSeal® 1000.
