A typical spherical separator is shown in Figure 4-3. The same four sections can be found in this vessel. Spherical separators are a special case…
Choking, or expansion of gas from a high pressure to a lower pressure, is generally required for control of gas flow rates. Choking is achieved…
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…
To assure that the liquid and gas reach equilibrium at separator pressure a certain liquid storage is required. This is defined as “retention time” or…
A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower…
The factor of proportionality in the previous equations is called the Moody friction factor and is determined from the Moody resistance diagram shown in Figure…
The choice of separator operating pressures in a multistage system is large. For large facilities many options should be investigated before a final choice is…
The German Lurgi Company and Linde A. G. developed the Rectisol® process to use methanol to sweeten natural gas. Due to the high vapor pressure…
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…
As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more…
