Cylindrical pressure vessel shell for reflux drums in distillation systems
Commonly used trade names and technical identifiers for Shell.
This component is used in the following industrial products
A vessel in a distillation column system that collects condensed overhead vapor and returns a portion as reflux to the column.
The pressure vessel that contains water/steam and facilitates heat transfer from combustion gases or heating elements to generate steam.
A pressure vessel designed to generate steam through heat transfer from combustion gases or other heat sources to water.

The shell provides pressure containment for the liquid-vapor mixture in distillation systems, maintaining system pressure for efficient separation while housing internal components and ensuring structural integrity.
Shell thickness is calculated using ASME BPVC Section VIII formulas considering design pressure, temperature, material properties, corrosion allowance, and weld joint efficiency, typically resulting in 6-25mm thickness for standard applications.
Carbon steel (SA-516) for non-corrosive services, stainless steel (304/316) for corrosive environments, and clad materials for cost-effective corrosion resistance in chemical processing applications.
