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…
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…
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…
In many refineries most of theC4’s and lighter are removed from the atmospheric column overhead distillate in the first column of the light end unit.…
Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the…
Re-entrainment is a phenomenon caused by high gas velocity at the gas-liquid interface of a separator. Momentum transfer from the gas to the liquid causes…
In order to develop a treater design procedure, the water droplet size to be used in the settling equation to achieve a given outlet water…
This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its…
The Bernoulli equation is a way of describing how the energy of a fluid changes along its path. It says that the sum of the…
Most oil-treating equipment relies on gravity to separate water droplets from the oil continuous phase, because water droplets are heavier than the volume of oil…
