Key findings
- Coating thickness imposes BOTH heat-transfer resistance (fluid -> sieve) AND mass-transfer resistance (to desorbed vapor).
- BOTH resistances scale with the SQUARE of coating thickness -> a thin-coating optimum (you cannot just coat thicker for more sorbent per area).
- Critically weighs designs against each other: granular vs coated vs finned.
- This thickness-squared law is the governing physics behind why coated beds have an optimum.
