AI Technical Summary
Technical Problem
The existing coke drum deheading valves experience thermal cycling issues due to extreme temperature variations, leading to weakened components and leaks, and require high steam pressure to maintain seals, increasing operational costs.
Method used
A floating seat plate that articulates with the gate to maintain a seal despite thermal expansion, isolating the valve body from process fluids and reducing steam leakage by using a bias system and INCONEL® bellows to accommodate thermal deformation.
Benefits of technology
The solution enhances the longevity of valve components by preventing leaks and reducing steam consumption, thus lowering operational costs and maintaining effective sealing under thermal cycling.
