Material selection and surface coating of coker valves

Coking is one of the most corrosive and abrasive environments in the refinery with a

temperature of over 1000 F under high pressure condition. The function of the coker valve is

to transport the fuel from heavy crude oil. Therefore these coker valves used more subject to

failure than other valves used. It is crucial to design a valve which would offer more

sustainability in the environment described above. The main research focus is to develop a

suitable material and coating for this coker valve which will be more corrosion resistive and

applicable at high temperature. This design will have to consider not only the properties of the

valves as they are made, but also cycling tests are to be taken during the testing procedures.

The work will include three major aspects, namely metallurgy/material selection, testing

procedures and Finite Element Analysis for computational simulation
