A vessel may be subject to more than one condition under different failure scenarios. For example, a low pressure separator may be subject to blocked…
In selecting an exchanger, one must know the advantages and disadvantages of each type. The three basic types of shell-and-tube exchangers are fixed tube sheet,…
To maintain pressure on a separator, a liquid seal must be effected in the lower portion of the vessel. This liquid seal prevents loss of…
Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the…
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low…
In dispersed gas units gas bubbles are dispersed in the total stream either by the use of an inductor device or by a vortex set…
This process uses propylene carbonate as a physical solvent to remove CO2 and H2S. Propylene carbonate also removes C2+ hydrocarbons, COS, SO2, CS2, and H2O…
Licensed by Shell the Sulfinol® process combines the properties of a physical and a chemical solvent. The Sulfinol solution consists of a mixture of sulfolane…
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…
The flow rate for gas through a given orifice area or the area required for a given flow rate is obtained by:
