To clean up amine, the rate of particulate generation must be slowed and the iron sulfide already in the amine filtered out. Reducing corrosion rates…
The iron sulfide particulates circulating in a dirty amine system have built up from a combination of factors. Foremost among these is inadequate filtering. There…
Running a sulfur recovery operation with dirty amine is analogous to deficit spending. You are borrowing against the future, but the day of reckoning will…
Symptoms of a dirty, corrosive amine system are: Carry-over of amine from the scrubbers. Dilution of the amine system with water due to reboiler leaks.…
Figure 4-1 is a process flowsheet showing how amine solution is circulated to various refinery scrubbers to absorb H2S. The lean amine chemically combines with…
The hot coke drum vapors are a valuable source of high-level heat. This energy, which is partially recovered in the combination tower heavy gas-oil pumparound…
Coker fractionators are subject to damaging pressure surges due to accidental flashing of water. The pressure surges results in the tray decks “ripping” away from…
A delayed coker combination tower is similar in design and function to an ordinary crude distillation tower; heat is removed and products are fractionated. Referring…
Coke that builds up in the coke drum overhead vapor line is responsible for most of the back-pressure incidents. Operators find that tearing the insulation…
