Phosphonated IminodisuccinatesA Calcite Scale Inhibitor with Excellent Biodegradability [PDF]
ACS Omega, 2022 Scale inhibitors are an extremely important chemical in upstream oil and gas field operations and water treatment industries. These inhibitors prevent nucleation and/or crystal growth of scales such as calcite and barite. This keeps the pipes and other equipment and surfaces free from deposits, allowing the maximum flow of aqueous fluids. However, many
