Valve designs preventing residue accumulation
Coke drum isolation, 4-way switch and overhead vapor valves typically experience the most severe conditions and are the focus of the greatest scrutiny within the process. Metso engineers have meticulously developed valves to tackle the extreme conditions these valves experience. For example, seat back cavities are designed to prevent residuum from entering in the first place and are more easily purged. Also two body purge ports are used instead of one to further prevent residuum accumulation in the valve.
Metso has gone one step further by applying the innovations and technologies developed for the severe-service valves to the ancillary process valves also likely to experience similar problems associated with coke residue.
The reliability offered by Metso’s NELES valves helps refineries to run more efficiently and meet yield targets. They also help to support overall system uptime and reduce maintenance costs and the frustration that comes with poorly performing valves.
Lower maintenance costs. Maximum yield and runtime
Metso brings over 25 years of delayed coking process experience in designing and building valves and assemblies. This experience and expertise results in innovative technologies proven to lengthen run-times and reduce costs.
