Instrumentation Diagrams (P&ID’s) represent the 190 Proof Superheater, Molecular Sieve Unit (MSU) and Condenser and Vacuum System, respectively. The scope of the supply is for a “state-of-the-art” Thermal Kinetics’ MSU ethanol dehydration system. The TKE system is designed to produce dry ethanol for three different operating conditions.
basic design of gas dehydration and sizing the molecular sieve dehydrator bed. This guideline will help reader to understand about gas dehydration methods, desiccant selection, bed sizing, regeneration design, operational problem, etc. Additional details of selecting molecular sieve will be presented. The application of the molecular sieve
Molecular sieve dehydration is the industry-standard method of removing water from natural gas upstream of cryogenic NGL/LPG recovery units when significant recovery of light hydrocarbons (ethane and propane) desired. The design of the dehydration system is regeneration and subsequent cool-down operations canhowever,, have negativeunforeseen

This guideline gives methods to understand basic design of gas dehydration and sizing the molecular sieve dehydrator bed.
Schematic of a molecular sieve dehydration unit.
CO2 dehydration can be performed by absorption, typically into triethylene glycol (TEG) followed by desorption or by adsorption on a solid (typically a molecular sieve) followed by desorption.
Introduction - Molecular Sieve Adsorbents • Strong adsorptive force to remove many gas or liquid impurities to very low levels (ppm or less) • Differ from other adsorbents in the form of their isotherms which have a high adsorption capacity for relatively low concentrations of the adsorbate
Optimal design and operation of molecular sieves for gas …
Select good-quality molecular sieves; Ensure proper loading of the molecular sieve; Implement a regeneration profile that prevents the formation of liquid water; Analyze spent molecular sieve samples. Based on the data presented, it might seem as though molecular sieve units are the source of many problems in a gas processing plant.
Molecular sieves are loaded in vertical adsorbers. The gas to be dried goes through the adsorbers, and water is captured along the way. Within a few hours (12 to 36 hours depending on the size of the adsorption unit), a given bed is saturated with water and it has to be regenerated.
