The area of the fire tube is normally calculated based on a heat flux rate of 10,000 Btu/hr-ft2. The fire-tube length can be determined from:…
Developed by Allied Chemical Company, this process is selective toward removing sulfur compounds. Levels of CO2 can be reduced by approximately 85%. This process may…
This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid…
Pilot-operated relief valves use the pressure in the vessel rather than a spring to seal the valve and a pilot to activate the mechanism. Figure…
Aerial coolers are often used to cool a hot fluid to near ambient temperature. They are mechanically simple and flexible, and they eliminate the nuisance…
The process of coalescence in oil treating systems is time dependent. In dispersions of two immiscible liquids, immediate coalescence seldom occurs when two droplets collide.…
Process outlet temperature in an aerial cooler can be controlled by louvers, fan variable speed drives, blade pitch or recirculation of process fluid. As the…
Next to sales contract specifications, corrosion protection ranks highest among the reasons for the removal of acid gases. The partial pressure of the acid gases…
There are four major types or basic configurations of separators, generally available from manufacturers which are as follows: 1. Vertical 2. Horizontal Single Tube 3.…
In the absence of any laboratory data, correlations exist that relate viscosity and temperature, given the oil gravity. The following equation relating viscosity, gravity, and…
