As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more…
Each relief valve should be equipped with inlet piping no smaller than the valve inlet flange size, and inlet piping should be as short as…
Dissolved gas designs take a portion of the treated water effluent and saturate the water with natural gas in a contactor. The higher the pressure…
SulfaTreat process is similar to the iron sponge process. It uses a patented proprietary mixture of ferric oxide and triferric oxide to react with H2O…
Remembering that the weight of each component is the number of moles of that component times its molecular weight (pounds = MW X moles), the…
In modern refinery practice the distillation of atmospheric residue is accomplished under high vacuum conditions in a specially designed tower whose internal equipment ensures a…
As with vertical two-phase separators, a minimum diameter must be maintained to assure adequate gas capacity. In addition, vertical threephase separators must maintain a minimum…
This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid…
Separators are designed in either horizontal, vertical, or spherical configurations. Figure 4-1 is a schematic of a horizontal separator. The initial gross separation of liquid…
A drain system that is connected directly to pressure vessels is called a “pressure” or “closed” drain system. A drain system that collects liquids that…
