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…
These units are designed to allow hydrates to form and to melt them with the heat of the incoming gas stream before they can plug…
The area of the fire tube is normally calculated based on a heat flux rate of 10,000 Btu/hr-ft2. The fire-tube length can be determined from:…
The major cause of foam in crude oil is the appearance of impurities, other than water, which are impractical to remove before the stream reaches…
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 principal items of construction that should be present in a good liquid-gas separator are the same regardless of the over-al1 shape or configuration of…
Conventional Valve, Balanced-Bellows Valve, or Pilot-Operated Valve The corresponding equations for liquid flow are the following: Note that a preliminary orifice size must be determined…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
Disposal piles are large diameter (24- to 48-inch) open-ended pipes attached to the platform and extending below the surface of the water. Their main uses…
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…
