Publication number: 20240071740Abstract: A method of analyzing the residual of a polymeric scale inhibitor in water containing SO42?, such as produced water, is disclosed. The water also contains a polymeric scale inhibitor that includes 2-acrylamino-2-methylpropane sulfonic acid (AMPS). In the method, an amount of SO42? in a sample of the water is measured. A water soluble salt is introduced into the sample of water, and the salt removes SO42? from the water sample resulting in a low SO42? water sample. The low SO42? water sample is then analyzed, and the analysis includes: determining a sulfur level in the low SO42? water sample, and performing a thermodynamic scale prediction to calculate the amount of SO42? ions remaining in the low SO42? water sample. A concentration of the polymeric scale inhibitor in the water sample is then determined based on an inductively couple plasma (ICP) analysis.Type: ApplicationFiled: August 29, 2022Publication date: February 29, 2024Inventors: Tao CHEN, Qiwei WANG, Faisal ALRASHEED
