Abstract
A seat system for a coke drum deheading valve can include a groove in the surface of the seat for supplying a lubricant to the surface of the seat. Various channels can be formed in the body of the seat that connect to the groove. In this way, lubricant can be flowed through the channels and into the groove to provide lubrication between the surface of the seat and the blind. The seat system can also include a split ring packing gland to facilitate the formation of a seal within the deheading valve. The split ring packing gland can be used to retain and compress packing positioned between a retaining ring and a dynamic seat such that when the packing is compressed, an improved seal is formed. By improving the seal, less steam can be required during the delayed coking process thereby increasing the efficiency of the system.
