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.

Inhibition Performance

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).

Polyaspartic acid (PASP) was prepared by the means of polymerizing maleic anhydride and ammonia solution. In order to find optimal condition of synthesizing PASP, we made a set of experiments on proportion of material, temperature and time of polymerization in the single condition, and compared PASP with other scale inhibitors about the performance of scale inhibition and biodegradation. The results show: the optimal proportion of material is 1:1.1, the temperature of polymerization is 160°C, and the time of polymerization is 1h. Under above condition, we synthetized the PASP its inhibiting efficiency can reach over 95%, and biodegradation rate reaches 70%.

Intermediate vector polysuccinimide (PSI) was prepared by polymerization of malefic acid and ammonia at 180°Cin this article. Hydrophilic polyaspartic acid (PASP) derivative was prepared from amino-sulfonic and PSI; Lipophilic PASP derivative was prepared from PSI and diisopropylamine. Their scale inhibition rates of calcium carbonate were evaluated by static scale experiments. The inhibition rate of calcium carbonate was 90.2% when n(amino-sulfonic): n(PSI) =1:14 and the dosage of pharmaceutical was 12mg / L. The inhibition rate of calcium carbonate was 87.6% when n(diisopropylamine):n(PSI)=1:8 and the dosage of pharmaceutical was 15mg /L. The calcium carbonate that collected from static state experiments was analysised by scanning electron microscope (SEM). The results showed that polyaspartic acid derivatives were synthesized which had the best overall performance when n (amino-sulfonic): n (PSI) = 1:14.
