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…
The way in which the process temperature is controlled varies. In a heater, a temperature controller measures the process temperature and signals a fuel valve…
The flow of a compressible fluid through an orifice is limited by critical flow. Critical flow is also referred to as choked flow, sonic flow,…
Two common internals not discussed are coalescing plates and sand jets. It is possible to use various plate or pipe coalescer designs to aid in…
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…
TEMA standards provide for two classes of shell and tube exchanger qualities. Class C is the less stringent and is typically used in onshore applications…
Cyclone separators are widely used in various industries for the separation of solid particles from gas or liquid streams. The capacity of a cyclone separator…
Before choosing a wall thickness it is necessary to choose a pressure rating for the coil. Typically, the high-pressure coil (L1) is rated for the…
The most common form of parallel plate interceptor used in oil facilities is the corrugated plate interceptor (CPI). This is a refinement of the PPI…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
