With the known temperatures on each end of the coil, the heat duty for each coil can be calculated from the heat transfer theory. Since…
For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
An oscillating droplet of oil becomes unstable when the kinetic energy is sufficient to make up for the difference in the surface energy between the…
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…
It should be clear from the description of LTX units that the lower pressure separator in an LTX unit is a simple form of cold-feed…
Produced wellhead fluids are complex mixtures of different compounds of hydrogen and carbon, all with different densities, vapor pressures, and other physical characteristics. As a well stream flows from the hot, high-pressure petroleum reservoir, it experiences pressure and temperature reductions. Gases evolve from the liquids and the well streamchanges in character.
It can be shown mathematically that an efficient design must have a high gas induction rate, a small diameter induced gas bubble, and relatively large…
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or…
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…
Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the…
