CaCO3 in MEG during gas production!

Elementary, my dear elementary, the answer lies in your question itself. You are expecting CaCO₃ after 6/7 years but not so early. Look for the conditions you are expecting after long years of operations, they are actually created today for your production activity.

CaCO₃ and many inorganic salts are plenty in sea water. Regenerating MEG after off shore operations actually gives you salts of Na, Ca, Mg etc. Natural gas gushing out takes vapor droplets along in larger quantity so early in your operations, why?

Hope you find the solution.

Dear Heita, if you do not suspect your new off shore platform's equipment throwing more sea water with the gas, the other suspect is your MEG itself.

CaCO₃ is used in production of ethylene glycol. Ethylene gas is chlorinated to form ethylene dichloride, which in turn is reacted with lime to produce ethylene glycol.

Elemntary, my dear elementary. If you find salts of Na, Mg etc., it is sea water. If its only Ca, it your MEG contamination.

Look for the details, you get your answers.

Good luck,
