P-5: Molecular Sieve Dehydration
Molecular Sieve: Includes two sections:
P-5 Molecular Sieve Dehydration Process
P-6 Molecular Sieve Adsorbers
Section 1 - Molecular Sieve Dehydration Process
This section describes the principles and operations of solid bed adsorption plants for fluid stream dehydration.
Covered Subjects:
Principles of molecular sieve dehydration
Description of equipment in an adsorption plant
Process flow of common adsorption plants
Adsorbent capacity, plant efficiency and methods of increasing capacity
Adsorbent regeneration process
Operating procedures for adding new adsorbent to towers, removing air, start-up, manual tower switching, shutdown and routine operation
Procedures for troubleshooting loss of capacity and efficiency
Breakpoint test
Section 2 - Molecular Sieve Adsorption Tower
This section describes the adsorption vessels used in molecular sieve dehydration plants. and the procedures for operations.
Covered Subjects:
Description of the absorption towers; bed support, adsorbent, and switching valve and piping arrangements
Procedures for determining the weight of moisture contained in gas
The capacity of adsorbent and the mass transfer zone
The procedure to regenerate the adsorbent with hot gas
Procedure to determine plant capacity and methods of increasing capacity
Both Metric and English units of measurement are used so students can work in units with which they are familiar.
Questions and problems are included throughout the text with answers in the back that allow students to check their understanding of the subject.
Comprehensive knowledge assessment tests are included at the end of each section.
The Molecular Sieve Series Knowledge Validation Test provides the answers to both USCS and SI unit validation test questions in the manuals for self-grading or for supervisor to grade test of employees. Also included scoring information. Test answers in pdf format will be emailed.
Alternatively, PLP will review and score completed test. Contact PLP for pricing.
An experienced PLP instructor can travel to your site to lead a classroom training program. Contact PLP for more information.
