TEG System ยท Flash Gas ยท Reboiler Fuel ยท Recovery Economics
Understand TEG absorber losses, regenerator fuel, flash gas recovery, and optimization strategies
It calculates TEG dehydration gas losses using GPSA methodology, including flash gas, stripping gas, reboiler fuel, and recovery economics.
TEG dehydration systems experience flash gas losses, stripping gas losses, and reboiler fuel consumption.
Yes, the calculator includes annual loss value estimates and vapor recovery unit (VRU) payback analysis.
The three main gas loss sources are flash gas from the glycol flash tank, stripping gas used in the regenerator still column, and reboiler fuel gas consumption. Without recovery equipment, total losses typically range from 1.5-3% of throughput.
Installing a flash gas recovery unit (VRU) can reduce total gas losses from 1.5-3% down to 0.8-1.5%. The industry target is less than 1.5% total gas loss from dehydration systems.
Typical stripping gas rates are 2-10 scf per gallon of TEG circulation. Stripping gas improves TEG lean purity from about 98.5% to 99%+, enabling deeper water dewpoint depression.
