Seeking information on the material used for equipment in the atmospheric tower of a vacuum distillation unit?
Thread Content
The crude oil medium is as shown in the attached diagram. The design temperature for the atmospheric pressure tower is 380°, and the design pressure is 0.25 MPa. The material we selected is Q345R+S11306; however, the client wants to switch to Q345R due to cost considerations. Can Q345R meet the corrosion requirements of the medium?
Insisting on not changing and keeping delaying things until the end, the client eventually gives in.
This one. . . Do you think using Q345R can meet the material requirements?
So, if nothing is changed, some clients just create problems for no reason, without even realizing it. :lol
According to the material selection guidelines, no changes. After the changes, all the responsibility lies in the design
Hold off on your opinion for now; if it really can’t be avoided in the end, consider using segmented composite panels plus carbon steel
It’s likely a small private refinery.
Thank you for your reply. They haven’t responded to me yet regarding the delay in the timeline over there; it’s still being postponed:dizzy:
Design is the first step in ensuring operational safety, and no compromises are allowed. It seems that last year, a tower at one facility had to be shut down due to leaks caused by corrosion
