Resource Utilization of Waste Medicine: A Case of Furazolidone Used for Oilfield Water Treatment
CHEMICAL ENGINEERING & TECHNOLOGY(2024)
Abstract
As a case study in the practical problem of how to solve the issue of waste medicine more reasonably, furazolidone (FZD) was investigated as an acidizing corrosion inhibitor and bactericide for oilfield water treatment. Gravimetric results indicate that FZD exhibits high inhibitory efficiency under acidic conditions. In addition, the corrosion inhibition performance decreases as the temperature increases. The adsorption of FZD on the surface of steel has been studied, and the experimental results indicate that the material exhibits the characteristics of a Langmuir-type adsorption isotherm. The thermodynamic results demonstrate that the adsorption behavior of FZD on the steel surface is that of an exothermic, spontaneous, entropy-decreasing process. Finally, the bactericidal activity of FZD was investigated. This work provides a simple and beneficial way to utilize a particular waste drug. To solve the problem of waste medicine more reasonably, furazolidone (FDZ) was employed in a case study to investigate its potential for application in oilfield water treatment as acidizing corrosion inhibitor and bactericide. FZD exhibits high inhibitory efficiency under acidic conditions. This work provides a simple and beneficial way to resource utilization of waste medicine. image
