For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
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…
SulfaTreat process is similar to the iron sponge process. It uses a patented proprietary mixture of ferric oxide and triferric oxide to react with H2O…
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…
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.…
It is normally a good idea to include a simple vortex breaker as shown in Figure 4-9 to keep a vortex from developing when the…
The ASME code requires every pressure vessel that can be blocked In to have a relief valve to alleviate pressure build up due to thermal…
For distillation services, as in condensate stabilization, tray design is well understood, and many engineers are more comfortable with trays than with packing. In the…
Flow regimes describe the nature of fluid flow. There are two basic flow regimes for flow of a single-phase fluid: laminar flow and turbulent flow.…
When thinking about emulsion stability, it may be helpful to realize that in a pure oil and pure water mixture, without an emulsifying agent, no…
