Acid – polyamino polyether methylene phosphonic acid (PAPEMP)

Structural Formula of PAPEMP Acid:

Product Features:

Aquacid 114 EX is a new kind of scale inhibitor for industrial water treatment. It has high chelation and dispersion effect with high value of calcium tolerance and scale inhibition effect. It can be used as scale and corrosion inhibitor in circulating cooling water system and oilfield of high hardness including calcium magnesium and barium sulfate scale inhibitor. It is stable in aqueous solution under a wide range of pH, temperature and pressure.

Polyamino polyether methylene phosphonate widens the operational conditions available with today’s standard technology by allowing operations with hard water at higher pH levels and greater salt concentrations. PAPEMP it is possible to operate at up to 300X calcite saturation because of its excellent calcium tolerance. As a result it controls up to three times as much calcium carbonate as ATMP or PBTC (operating at up to 100x calcite saturation).

Applications:

• • Aquacid 114 EX has excellent scale inhibition ability to calcium
    carbonate, calcium sulfate and calcium phosphate.
  • Aquacid 114 EX can efficiently inhibit the formation of silica scale, stabilize metal ions such as Zn, Mn and Fe. It effectively chelates metal ions including calcium, magnesium, iron and copper.
  • Aquacid 114 EX can be used as scale inhibitor for reverse osmosis system and multi-step flash vaporization system in which high salt concentration, high turbidity and high temperature are usually encountered (such as high temperature and high turbidity in coal vaporization system), accessory agent for woven & dyeing (for example, yellow turn back inhibition agent), as alternatives of EDTA, DTPA and NTA .
