I have a problem in deciding the number of beds used in dehydration for pre-treatment of LNG

 

One of the vendors has suggested a 5 bed for LNG pretreatment a 5 bed system is that you can reduce the regeneration rate by 66% by using a semi closed loop system . The downside is the additional vessel and associated costs. The other downside is that if water gets into the treater section it is harder to strip off the water.

 

 

A 3 bed system is capex friendly but opex wise costly 

 

 

Peak CO2 demand is 0.8 mole% 

 

Please suggest what should i go with
