AKSELOS SOLUTIONS FOR REACTORS

Oil refineries usually have several heavy-walled hydrotreater reactors. These vessels are built to operate at high temperatures and pressure. As a result, they are susceptible to brittle fractures, which can have catastrophic consequences.

An operator in North America suspected they could speed up the heat up and cool down processes to avoid unnecessary downtime.

To help, we undertook a structural analysis of the reactor, taking in data from 23 temperature sensors. Our simulation software provided actionable information to adjust the startup and cooldown speed. The result was a significant downtime reduction and a longer reactor life.
