Can the reactor be damaged when it experiences multiple temperature spikes?
Thread Content
The designed temperature of the reactor is 450°F; several times the temperature exceeded this value, reaching 600°F. What will be the consequences? Only the reactor itself is considered, without taking the catalyst into account. Should it be repaired? How to do it? Do you want to conduct a flaw detection?
The common approach to dealing with high operating temperatures is to activate the emergency pressure relief system, allowing the reactor to withstand rapid changes in temperature and pressure. Even if temperatures and pressures do not exceed critical levels, problems can still arise; moreover, sometimes the temperature exceeds the reactor’s design limits
Use at temperatures not exceeding the design temperature; the reactor can withstand the design pressure； If the temperature exceeds the design limit, the reactor can withstand a sharp drop in pressure; this is related to the material used in the reactor and falls under the category of material design. I only have a general understanding of this topic and am not very familiar with it; for detailed information, it is recommended that you consult the manufacturer of the reactor.
The reactor will be damaged. Pay special attention to the welded areas afterward. There have been leaks.
A qualified institution should be sought for assessment
It is recommended that you provide feedback to the reactor manufacturer in writing
Every piece of equipment has its own operating temperature. Exceeding this temperature does not necessarily mean the equipment can no longer be used, but it does increase the risks associated with its operation. This is something that must be taken into account in hydrogenation systems that operate under high temperature and pressure. Inspection agencies are also unlikely to decide easily whether such equipment can still be used, as the responsibility involved is significant. In state-owned enterprises, it is likely that they would consider replacing the reactor to resolve the issue at its root
Find a qualified special inspection company to thoroughly inspect the reactor welds and the base metal. Only then can a conclusion be drawn.
You need to ask the manufacturer about this. . .
