Dears,
We are facing high TEG losses in our company. Design capacity of TEG contactor is 75 MMCFD at 650 psig.
TEG Contactor Size:
Dia= 6'
T&T= 26'.6"
Six Bubble cap trays.
Design TEG circulation rate is 12 gpm
our operation team is unable to maintain 12 gpm flow, if they increase more than 2 gpm then glycol losses are very high and we don't filter separator on dry gas outlet. Presently gas production has reduced to 51 MMSCFD.
I discuss with some engineers and they told might gas superficial velocity has increased. whilst I calculated superficial velocity has also reduced on reduced flow and pressure. one of the engineer told me that regarding the superficial velocity indeed increase but you can't measure it. further he explained due to blockage some points gas velocity will increase and carry glycol with it.
I would like to hear more explanations on this issue and further trouble shooting guidelines.
Thanks
