Corrosion in T.L.E. exchanger and effect of heat with software analysis
In Marun petrochemical company there are some TLE (TRANSFER LINE EXCHANGER) that their lifetime reduced to 4 years instead of 30 years and after 4 years we saw sever*corrosion on one part of those T.L.E. that named Oval header and this happened in condition that other part of those TLE were safe and prefect. By using of thickness measurement devices we find that thickness reduced unusually on that part and after research and do computer analysis with fluent soft ware, it was recognized that on that part we have high temperature and when this out of rang temperature add to bad quality of water , corrosion increased whit high rate on that part and after more research it became obviously that it case by more excess air in furnace that located before this T.L.E. that this more air case to consuming more fuel to reach same furnace temperature so it concluded that inner coil fluid temperature increased and after received to T.L.E this case happened and deflector condition , creep in coil and material analysis confirmed that condition.
