Antiscalant ORG EV 2030 is a neutralised aqueous solution of organic acid. There are no special requirements regarding materials of construction of the dosing system.
Recommended injection points are either into the seawater make-up line after any external de-aeration and decarbonation equipment, or into the recycle brine stream at a suitable point after the blowdown and typically into the discharge of the recycle brine pump.
Antiscalant ORG EV 2030 is readily miscible with water in all proportions. It may be applied as the neat product, or as a solution in distillate and should be dosed continuously, and proportionately to the seawater make-up flow, to maintain the recommended dose level.
The dose level required will depend on a number of factors, including the quality of the seawater feed, TBT, recycle brine concentration factor, the type of distillation plant and frequency of application of the sponge ball cleaning system. Typical dose levels, when used in conjunction with a sponge ball cleaning system, are 0.8 to 1.0 mg/l at TBT 90 ºC and 1.8 to 2.0 mg/l at TBT 110 ºC. Detailed recommendations for any plant will be made on request.
Antiscalant ORG EV 2030 is effective against alkaline scale formation across the full range of top brine temperatures (TBT) in use today, It is particularly recommended for use in plants operating at top brine temperaturesgreater than 100 oC where total control of particulate fouling and sludging is critical to maintaining thermal efficiency. Field trial reports and reference lists are available on request.
Health and Safety
Antiscalant ORG EV 2030 is an aqueous solution of Polycarboxylic acid. From results of acute studies it is classed as non-toxic. A Material Safety Data Sheet is available on request.
Thermal Stability
Thermogravimetric analysis and differential scanning calorimetry have shown that Antiscalant ORG EV 2030 is stable up to a temperature of 200 oC.
Chemical Reactivity
Antiscalant ORG EV 2030 is not affected by chlorine or other oxidising biocides under normal conditions of use.
