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…
Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
The flow rate for gas through a given orifice area or the area required for a given flow rate is obtained by:
Back-pressure can affect either the set pressure or the capacity of a relief valve. The set pressure is the pressure at which the relief valve…
The relief header is a system of piping connecting the outlets of all the relief valves into a common pipe or header that goes to…
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…
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…
Before the vessel fabrication can proceed, the fabricator will develop complete drawings and have these drawings approved by the representative of the engineering firm and/or…
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…
