Refinery Process Pipe Carbon Deposits - Restrictions to Flow
Refinery Process Pipe Carbon Deposits - Restrictions to Flow
(OP)
Gentlemen
I'm new to the industry and working on a petroleum process system where I've been asked to upgrade the alloy of some 4" ID pipes to prevent "carbon fiber" growth, which occurs in the section seeing over 500C. The carbon fibers grow at Fe sites and end up restricting the flow through the pipe.
How big of an issue is this in refineries? How often are plants shut down to pig or remove such deposits? I've been told that this plant shuts down every 18 months to remove these fibers, and I've been asked to find a better alloy for the pipe. Currently they are using 316 SS.
Thx for any comments on the problem and any alloy or coating suggestions. I'm curious about how much revenue is being lost due to this problem in the industry ...so I can justify a possibly expensive solution.
