AbstractGiven the special performance of nanosilica with its small size, large specific surface area and high surface activity, nanosilica containing reactive amino group (denoted as SiO2–NH2) and polysuccinimide were allowed to take part in polymerization reaction to afford SiO2–NH2 modified polyaspartic acid (denoted as SiO2–NH2/PASP), a potential polymer scale inhibitor with good water solubility for industrial circulating water. The scale inhibition performance of the as-prepared SiO2–NH2/PASP was evaluated by static scale inhibition test; and its scale inhibition mechanism was explored by means of scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Results indicated that SiO2–NH2/PASP exhibits excellent scale inhibition performance against CaSO4 and CaCO3 at very low concentrations (optimum scale inhibition rate of 100% and 68%, respectively), and the presence of 5 mg/L of SiO2–NH2/PASP greatly increases the inhibition efficiency of CaSO4 and CaCO3 scale by 21% and 53%, obviously higher than that of pure PASP.

Static and dynamic experiments were used to evaluate scale inhibition performance of polyaspartic acid derivative (PASP-SEA-ASP). The static experiments showed that the PASP-SEA-ASP had good scale inhibition performance and the scale inhibition rate exceeded 80% when the PASP-SEA-ASP was 2 mg•L-1 and the solution temperature was 40 OC. In the dynamic experiments, almost no scale formed on the heat transfer surface and the fouling thermal resistance decreases extraordinarily with PASP-SEA-ASP treatment experiment compared with the experiment without treatment. The PASP-SEA-ASP could be used in industrial cooling water systems.

An environment-friendly and multifunctional agent for industry circulation cooling water, polyaspartic acid derivatives with dihydroxyl group(DHPAP) was synthesized in aqueous solution. The FTIR spectrum of DHPAP was analyzed. Static experiments were carried out to validate scale inhibition performance of DHPAP. The scale inhibition ratios exceed 90% when 8 and 10 mg/L DHPAP under solution temperatures of 80 and 60°C, respectively. The scale inhibition ratios increase by increasing the DHPAP concentration with 6 and 8 mg/L under heating times of 10 and 6h, respectively. And the scale inhibition ratios are over 90%.

The deposition of BaSO4scale is always found in the oilfield. It is difficult to be removed. Therefore, it plays a negative role to the production. The effects of temperature and water chemistry on BaSO4scale have been investigated by using the conductivity method in this work. An environment-friendly copolymer was prepared to control the scaling of BaSO4. The copolymer was proved by static scale inhibition method, and weight-loss test that it has excellent scale inhibition performance and corrosion inhibition efficiency. Furthermore, FTIR spectra was used to prove that the scale inhibitor was polyepoxysuccinic acid (PESA).
