Vessel Supports Small vertical vessels may be supported by angle support legs, as shown in Figure 12-11. Larger vertical vessels are generally supported by a…
Most commonly used water treating equipment items rely on the forces of gravity to separate the oil droplets from the water continuous phase. The oil…
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…
This is the bottom product from the atmospheric distillation of the crude oil. Most crude oils are distilled in the atmospheric crude oil tower to…
The question always comes up of which fluid to put in the tubes and which fluid to put in the shell. Consider placing a fluid…
Re-entrainment is a phenomenon caused by high gas velocity at the gas-liquid interface of a separator. Momentum transfer from the gas to the liquid causes…
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…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
Figure 2-5 deals with a simple single-stage process. That is, the fluids are flashed in an initial separator and then the liquids from that separator…
