Scale and corrosion inhibitor PBTCA application areas

Oilfield water injection system: In the process of oilfield extraction, water is usually injected into the oil formation in order to maintain the pressure of the wells and increase the recovery rate. During the water injection process, calcium and magnesium ions in the water may form insoluble precipitates with carbonate and sulphate, leading to scaling of pipes and equipment.

Comparison of PBTCA and PAAS

  1. Scale inhibition properties:
    • PBTC: It mainly prevents scale formation by forming complexes with metal ions.
    • PAAS (Polycarboxylic Acid Scale Inhibiting and Dispersing Agent): It can disperse the microcrystals or sediment of calcium carbonate, calcium sulphate and other salts in the water without precipitation, so as to achieve the purpose of scale inhibition.
  2. Dispersing performance:
    • PBTCA: It has good dispersing performance and can hinder the aggregation and deposition of tiny particles and solid particles.
    • PAAS: Excellent dispersing performance, especially suitable for high pH, high alkalinity and high hardness water quality.

Comparison of PBTCA and HEDP

  1. Corrosion Inhibitors performance:
    • PBTC: At low temperature, PBTCA has excellent scale inhibition performance against calcium carbonate scale. With the increase of calcium ion + alkalinity concentration, its scale inhibition rate decreases, but still can maintain a high scale inhibition effect.
    • HEDP(Hydroxyethylidene Diphosphonic Acid): It can also form stable complexes with calcium ions, especially hexacyclic chelate, which can effectively inhibit the generation of calcium carbonate scale. At low temperature, HEDP also shows remarkable scale inhibition performance, and can effectively prevent the formation of scale layer at low concentration.
  2. Matching performance:
    • PBTCA: It has good compatibility with other scale and corrosion inhibitors and can be used together to enhance the scale inhibition effect.
    • HEDP: It has good compatibility with other scale inhibitors (e.g. polycarboxylates) and can be used together to enhance the scale inhibition effect.

Comparison of PBTCA and EDTMPS

  1. Scale inhibition performance:
    • PBTCA: It can form insoluble precipitates with calcium, magnesium and other metal ions, preventing the deposition and scaling of hard water salts. It also maintains good scale inhibition performance at high temperatures and is suitable for scale inhibition applications in high temperature environments.
    • EDTMPS (Ethylenediamine Tetramethylene Phosphonic Acid): It has excellent metal chelating ability, and can form stable complexes with a variety of metal ions, effectively blocking the precipitation and scaling of metal ions. It is especially suitable for controlling the scaling of calcium and magnesium ions in water, and can effectively prevent the generation of limestone and chalk.
  2. Corrosion inhibition performance:
    • PBTCA: With certain corrosion inhibition performance, it can form a protective film on the metal surface and reduce the corrosion reaction between metal and water.
    • EDTMPS: As a cathodic type corrosion inhibitor, it has a high corrosion inhibition rate, but its direct corrosion inhibition performance may be slightly inferior compared to PBTCA.
  3. Tolerance to impurities:
    • PBTCA: It is more adaptable to the change of water quality, and can play a stable scale inhibition effect under different water quality conditions.
    • EDTMPS: It has less influence on the interference of organic and inorganic impurities in water, and its stability is also stronger.
