Rochem Vaptreat Liquid

DESCRIPTION 

 

ROCHEM VAPTREAT LIQUID is a concentrated liquid blend of synthetic polymers and defoaming agents formulated to prevent scale deposits and foaming in high and low pressure evaporators. 

 

GENERAL SPECIFICATIONS 

 

Appearance   : Pale yellow liquid. Flash Point  : None  pH of 1% Solution : 9.2 Specific Gravity  : 1.09 

 

ADVANTAGES 

 

VAPTREAT LIQUID prevents scale formation by crystal distortion, dispersion, and absorption of scales forming minerals. It also prevents foaming and carry-over thus maintaining distilled water quality. Crystal Distortion – As soluble minerals are forced out of solution during evaporation they go through an intermediate crystal stage before forming dense deposits.  VAPTREAT LIQUID reacts with the crystals causing them to be distorted and irregularly shaped.  The distorted crystals do not form dense and uniform deposits which would adhere to evaporator surfaces. Dispersion and Absorption – VAPTREAT LIQUID disperses solid materials formed during evaporation by absorbing them into the polymers.  The polymer gives the absorbed particles electrical like charges causing them to repel each other and therefore preventing agglomeration and deposition. 

 

APPLICATION 

 

VAPTREAT LIQUID should be fed continuously to the evaporator feed inlet line from a dosage tank. VAPTREAT LIQUID can be diluted with fresh water and the feed solution should be dosed using an eductor or positive displacement metering pump. 

 

DOSAGE 

 

The standard dosage, applicable to most systems, is 15-30 ml of Vaptreat per ton of distillate produced. This is based on the rated production capacity of the evaporator.  Example: In a 25 ton/day evaporator, treatment used = 25 x 30 ml = 750 ml of Vaptreat per day.  Flow rate calculation: Mix 750 ml of Vaptreat with water to the dosage tank capacity (say 50 ltrs). Flow rate = 50 ltrs/24 x 60 = 35 ml per minute setting. This will last 24 hrs. Our ROCHEM Service Engineer will readily guide you on the correct dosage. 

 

If is preferred that the evaporator be clean and free of deposits before VAPTREAT LIQUID is introduced.   VAPTREAT LIQUID will clean up moderate amounts of existing deposits.   The dosage rate needs to be double of the recommended treatment rate during the clean up period. 

 

HANDLING 

 

No special precautions required.  Use the same care as in handling other chemicals used for maintenance.
