water glycol evaporation
water glycol evaporation
(OP)
I have to reduce the evaporation rate of a water-glycol fluid (oughto safe 620). The fluid is inside a tank, about 150 Litres capacity, that cannot be pressurized, the level of the fluid can change from 50 to 100 cm. The temperature range is 15-50°C. The solution shuld be the cheapest.
Can you help me? Thank you for any idea!

RE: water glycol evaporation
If the vent is open to atmosphere and you have to leave it open, the only thing that comes to mind is to install some sort of condenser coil in the vent line that will condense the water vapor and return it to the tank (there won't be any significant amount of glycol in the water phase).
Why does the fluid get up to 50C, can you change this? At 50C, the vapor pressure above the fluid of water is going to be much higher than at 15C and that is directly attributing to the losses. The cheapest solution is going to cotinue to make up water to the system every so often to maintain concentration.
