The liquid flow rate in moles per day for a given inlet stream can be determined from Equation 3-17. In our example, for an inlet…
A pipe that releases gas to disperse into the atmosphere is called a vent. If the gas is burned at the tip, it is called…
The flow of a compressible fluid through an orifice is limited by critical flow. Critical flow is also referred to as choked flow, sonic flow,…
In large facilities oil is typically sold through a LACT unit, which is designed to meet API Standards and whatever additional measuring and sampling standards…
Federal regulations and most authorities having jurisdiction require that “free oil” be removed from deck drainage prior to disposal. It is extremely difficult to predict…
The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
Pressure Relief Devices All pressure vessels should be equipped with one or more pressure safety valves (PSVs) to prevent overpressure. This is a requirement of…
When subjected to a magnetic induction B, an elementary volume v of magnetizable substance acquires local magnetization M, where M is the magnetic moment of…
In vertical separators, a minimum diameter must be maintained to allow liquid drops to separate from the vertically moving gas. The liquid retention time requirement…
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…
