The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different…
In condensate stabilizers, trays generally have 70% equilibrium stage efficiency. That is, 1.4 actual trays are required to provide one theoretical stage. The spacing between…
In the gravity settling section the liquid drops will settle at a velocity determined by equating the gravity force on the drop with the drag…
Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
Liquid carryover and gas blowby are two common operating problems. Liquid carryover occurs when free liquid escapes with the gas phase and can indicate high…
Equipment manufacturers have modified the CPI configuration for horizontal water flow perpendicular to the axis of the corrugations in the plates as shown in Figure…
These units are designed to allow hydrates to form and to melt them with the heat of the incoming gas stream before they can plug…
This equation, which is also sometimes called the Weisbach equation or the Darcy-Weisbach equation, states that the friction head loss between two points in 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…
