Antiscalant ORG EV 2030 has been developed with enhanced scale control and dispersant properties to give improved control of fouling throughout the plant, reducing cleaning frequencies and the associated costs.
Technical Bulletin
Description :
Antiscalant ORG EV 2030 is a high performance liquid product for the control of scaling and particulate fouling in seawater multi-stage flash distillation plants. It is a multifunctional product based on polycarboxylic acid chemistry.
Antiscalant ORG EV 2030 has been developed with enhanced scale control and dispersant properties to give improved control of fouling throughout the plant, reducing cleaning frequencies and the associated costs.
Application :
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.
Dose :
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 provide on request.
