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…
Laboratory testing of a particular oil at various temperatures is the most reliable method of determining how an oil behaves. ASTM D 341 outlines a…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
Erosional flow criteria will almost always govern in choosing the diameter. Sometimes it is necessary to check for pressure drop in the coil. Typically, pressure…
These are thin diaphragms held between flanges and calibrated to burst at a specified static inlet pressure. Unlike relief valves, rapture discs cannot reseal when…
A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower…
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…
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…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
