Antiscalant ORG EV is an aqueous solution of a synthetic polymer based on hydrolysed maleic anhydride.Used alone or in conjunction with a sponge ball cleaning system its effectiveness has been demonstrated in distillation plants operating with top brine temperatures up to 120 ºC.
Technical Bulletin
Description :
Antiscalant RXSOL ORG EV is a high performance liquid product for the control of alkaline scaling (calcium carbonate and magnesium hydroxide) in all types of seawater distillation plants. Antiscalant ORG EV is an aqueous solution of a synthetic polymer based on hydrolysed maleic anhydride.Used alone or in conjunction with a sponge ball cleaning system its effectiveness has been demonstrated in distillation plants operating with top brine temperatures up to 120 ºC.
Application :
Antiscalant RXSOL ORG EV can be used in all types of distillation plant but is particularly suitable for use in multi-stage flash plants.
Usage and Dose :
Antiscalant RXSOL ORG EV is an aqueous solution of an organic acid and as such is corrosive in its concentrated form. Corrosion resistant dosing equipment must be used. Examples of suitable materials are 316L stainless steel and PVC or other plastic materials. 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 RXSOL ORG EV is 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 1.2 mg/l at TBT 90 ºC and 2.0 to 3.0 mg/l at TBT 110 ºC. Detailed recommendations for any plant will be made on request.
