“…In principle, it involves measurements of the increasing pressure caused by scale deposition on the test tube wall. Scale inhibition efficiency is represented by the ratio of the time needs to obstruct the tube flow in the presence and the absence of the inhibitors (Macedo et al 2019;Sanni et al 2019).…”

During the operation of the circulating cooling water system, the inorganic scale deposition may cause technical problems, such as reduction of heat transfer efficiency in cooling systems and obstruction of pipes. In the industry, chemicals are often used as scale inhibitors in scale deposition control, antiscalants popular in industry are generally phosphorus and nitrogen containing chemicals, which may lead to eutrophication. However, increasing environmental concern and discharge limitations have guided antiscalants to move toward biodegradable, nontoxicity and cost-effectiveness. This paper reviews current researches on application of using bio-materials as scale inhibitors, including proteins and amino acids, polysaccharides, plant extracts, microbial reagents, and microbiological product. The non-bioaccumulation, low cost, readily biodegradability and sustainably available characters promote the development of green scale inhibitor chemistry.

Tujuan dari penelitian ini adalah untuk mengetahui kinerja dari dua jenis inhibitor, yaitu inhibitor A (Glycol base) dan inihibitor B (Amine base) yang digunakan untuk menurunkan reaksi korosi dalam media larutan air garam (brine water) yang dijenuhkan dengan CO2. Kinerja dari kedua jenis inhibitor ini diukur menggunakan metode elektrokimia, pemindaian mikroskop elektron (SEM) dan difraksi sinar X. Efi siensi inhibitor dihitung dari kepadatan arus korosi, ketahanan arus (Icorr), dan polarisasi (Rp). Hasil dari metode elektrokimia menunjukkan bahwa efi siensi inhibitor meningkat dengan meningkatnya konsentrasi. Kedua inhibitor bertindak sebagai inhibitor yang baikn pada konsentrasi 250 ppm dengan efesiensi optimum sebesar 89 % (inhibitor A) dan 96 % (inhibitor B). Hasil dari Scanning Electron Microscopy (SEM) terhadap permukaan baja karbon menunjukkan transformasi morfologi baja karbon menjadi lebih baik setelah penambahan inhibitor. Perilaku adsorpsi inhibitor pada permukaan baja adalah bersifat kimia dan mematuhi hukum penyerapan isotermal Langmuir.

“…Furthermore, some polymeric inhibitors of polyacrylates, polyphosphino carboxylates, polymaleates, and polyacrylamides are adequately stable at high temperatures reaching 200 °C; making them suitable and effective for calcite formation inhibition in oil reservoirs . Most of the reported studies focus on investigating the performance of several phosphonates and carboxylates inhibitors due to their outstanding efficiency in the oilfield. − In spite of the good inhibition performance, those inhibitors are not classified as environmental-friendly because they possess a degree of toxicity. The increased environmental awareness and strict regulations have pushed toward investigating environmental-friendly inhibitors either by modifying the structures of the state-of-the-art inhibitors or by proposing new green ones. − …”

Calcite Scale Inhibition Using Environmental-Friendly Amino Acid Inhibitors: DFT Investigation

et al. 2021

Scale prevention is a long-term challenge. It is essential for ensuring the optimum utilization of oil and gas wells and minimizing economic losses due to disruptions in the hydrocarbon flow. Among the commonly precipitated scales is calcite, especially in oilfield production facilities. Previous studies on scale inhibitors have focused on investigating the performance of several phosphonates and carboxylates. However, the increased environmental awareness has pushed toward investigating environmental-friendly inhibitors. Research studies demonstrated the potential of using amino acids as standalone inhibitors or as inhibitor-modifying reagents. In this study, 10 amino acids for calcite inhibitors have been investigated using molecular simulations. Eco-toxicity, quantum chemical calculations, binding energy, geometrical, and charge analyses were all evaluated to gain a holistic view of the behavior and interaction of these inhibitors with the calcite {1 0 4} surface. According to the DFT simulation, alanine, aspartic acid, phenylalanine, and tyrosine amino acids have the best inhibitor features. The results revealed that the binding energies were −2.16, −1.75, −2.24, and −2.66 eV for alanine, aspartic acid, phenylalanine, and tyrosine, respectively. Therefore, this study predicted an inhibition efficiency of the order tyrosine > phenylalanine > alanine > aspartic acid. The predicted inhibition efficiency order reveals agreement with the reported experimental results. Finally, the geometrical and charge analyses illustrated that the adsorption onto calcite is physisorption in the acquired adsorption energy range.
