Mist eliminators, consisting either of knitted wire mesh pads (demisters) or corrugated sheet metal vanes, are often used in critical services to improve separation of…
Entrained liquid droplets must settle out of the vapor stream as the vapor moves upward in a vertical separator or horizontally through the vapor space…
Vertical Separators The vertical separator (Figure 300-5) accommodates a tangential inlet, which assists removal of entrained liquid from vapor. Knockout drums which protect compressors are…
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…
