Effect of a Vector Wall on the Thermal Field in a SRU Thermal Reactor

Chun-Lang Yeh and Tzu-Chi Chien
Abstract—The effects of a vector wall on the thermal field in a SRU thermal reactor are investigated numerically. The FLUENT commercial code is employed to simulate the reacting and fluid flow in a SRU thermal reactor. Practical operating conditions from a petrochemical corporation in Taiwan are used as the inlet boundary conditions. It is found that the specific arrangement of a spiral-type vector wall holes results in a spiral motion behind the vector wall and thereby increases the residence time. In most cases, the average temperature in zone 2 is increased due to better mixing. The temperature difference across a vector wall becomes smaller due to better mixing. Among the locations of vector walls investigated, zone 1 temperature is the highest when the vector wall is located at 4m away from the zone 1 corner and is the lowest when the vector wall is located at 6m away from the zone 1 corner. The 36-hole spiral-type vector wall produces the strongest spiral motion, the highest average temperatures in the thermal reactors and the maximum sulfur concentrations at the exit.

Index Terms—SRU thermal reactor, choke ring, vector wall, thermal field.
