CSI INVENTED ANOTHER TYPE OF ABOVE GROUND SULPHUR SEAL
THAT IS MORE SAFER AND EFFICIENT AS SHOWN BELOW:

S_xSeal™ 1000
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 S_xSeal™ 1000. CSI’s patent-pending S_xSeal™ 1000 design ensures reliable sealing performance while enabling continuous SRU operation. Moreover, the S_xSeal™ 1000 is backed by CSI’s engineering expertise, expansive production capacity, and exemplary customer service. As such, CSI’s S_xSeal™ 1000 delivers the technical and commercial value you’ve come to expect from CSI for over 50 years.

The benefits of the S_xSeal™ 1000 include: 

• Safe, reliable sealing performance: The S_xSeal™ 1000 prevents process vapor from flowing downstream by using molten sulfur to actuate the seal.
• Easy to install: There is no need to dig 15-20 feet below grade and pour a concrete casing, as required with a conventional seal leg. CSI’s S_xSeal™ 1000 is installed entirely above grade with simple flange connections.
• Easy to maintain: With its above-grade design and easily removable head, CSI’s S_xSeal™ 1000 facilitates easy access and half-hour maintenance.
• Continuous SRU operation: CSI’s S_xSeal™ 1000 is designed to be serviced with the SRU operating at full capacity.

CSI ALSO MANUFACTURE AN IMPROVED SULFUR SEAL PRODUCT AS SHOWN BELOW:

S_xSeal™ 2000
For many years, refineries and gas plants have employed in-ground seal legs to prevent process vapor from entering the sulfur pit or collection vessel. While seal legs perform this function up to a point, they are prone to water intrusion and mechanical plugging, which result in costly repairs and unplanned SRU downtime. Above-ground sealing devices address many of these issues; but only CSI’s S_xSeal™ 2000 provides all the benefits of above-ground and in-ground sulfur sealing devices, without any trade-offs.  In addition, the S_xSeal™ 2000 is backed by CSI’s engineering expertise, expansive production capacity, and exemplary customer service.  As such, CSI’s S_xSeal™ 2000 delivers the technical and commercial value you have come to expect from CSI for over 50 years.

• Safe, reliable sealing performance
• Above-ground accessibility
• No filter screens to maintain
• Safe, visual confirmation of operating status
• ​No need shut-down, can be cleaned during operation
• No risk of ground water intrusion, cross-contamination, or plugging
• Supplemental relief path
