Three utility calculations for glycol dehydration system design and troubleshooting.
It estimates TEG losses, sizes flash tanks, and calculates heat exchanger duty for glycol dehydration systems.
Yes, this is a free glycol dehydration utility calculator available online.
The calculator includes TEG glycol loss estimation, flash tank sizing, and heat exchanger duty calculations.
TEG losses occur through three mechanisms: vaporization (0.01-0.05 gal/MMscf, temperature dependent), mist carryover from the contactor (0.02-0.10 gal/MMscf, demister dependent), and thermal degradation (1-3% per year at proper operating temperatures).
Flash tank sizing is based on the rich glycol flow rate, flash tank pressure (typically 50 psig), and required liquid residence time (typically 15 minutes). The tank separates dissolved hydrocarbons from the rich glycol before it enters the regenerator.
The glycol-glycol heat exchanger duty calculator estimates the heat transfer between hot lean glycol returning from the reboiler and cool rich glycol from the absorber. This recovers heat and reduces both reboiler fuel consumption and lean glycol cooler duty.
