Various Types of Fractional Distillation Process used in Process Plants [With PDF]

What is Fractional Distillation? Fractional Distillation or Distillation or Fractionation is the process of separation of components from a product or mixture (Crude Oil) by heating the mixture to a temperature at which several fractions of the compound will vaporize.  Normally when the mixture is heated, the component with the lowest boiling point will vaporize …

Pressure Vessel and Impact of Pressure

Understanding Pressure and Temperature in the context of Pressure Vessel Design [With PDF]

Many of the failures that we experience in the process industry are due to overpressure. Overpressure is the result of unbalance or disruption of normal flows of material and energy. This causes material or energy, or both, to build up in some part of the system. Overheating above design temperature may also result in overpressure, …

Schematic representation of a Piping Network

A short presentation on “Hydraulic calculation in piping networks”

What is a Piping Network? In general, networks consist of a number of components (Pipes, Ducts, Pumps, Valves, Filters, Orifice Plates, Fixed Pressure Drops and Nozzles) all connected together. The points at which the components may be joined to other components are referred to as nodes. Consider, for example, the simple system shown below, which …
