Assalamualaykum
Good morning to all the readers.
I'm a student and I have a task to evaluate glycol reboiler on dehydration plant. But I don't know how to do and where do I start to evaluate the glycol reboiler. As far as I know, firstly I have to calculate the actual duty of the reboiler at current condition, but now I stuck at the heat transfer calculation. The reboiler uses a direct fired heater.
What I have :
- Reboiler Temperature and Pressure (362F and 0 psig)
- Glycol flow rate (2 GPM)
- Feed Gas condition (706,7 psig, 92F, 31 mmscfd)
- Feed Gas moisture content after being dehydried (10,12 lb/mmscf)
- Moisture content of Rich Glycol (6% weight)
- Moisture content of Lean Glycol (0,9% weight)
- The glycol is TEG
- Fuel Gas composition (The composition is just the same as the dehydried gas)
From those data, I can calculate the water content of the feed gas, water that is being removed from the gas, the rich glycol composition (glycol, water, water that is being removed, hydrocarbon) and its mass flow, the composition of the lean glycol (glycol, water, hydrocarbon).
I need your help to guide me to do what should I do next and where I can get the literature. Thank You
