Aim
Hydrogen sulfide is one of the most harmful substances known in the drilling industry. Hydrogen sulfide can cause health, environmental, safety, and damage to property problems. Therefore, we conducted this study on a laboratory scale to make carboxylated carbon nanotubes and investigate their performance in removing hydrogen sulfide from drilling mud.
Materials and Methods
In the first step, we prepared multi-walled carbon nanotubes with 90%–95% purity. In the next step, we provide the drilling fluid. The fluid used in these experiments was a simple water-based mud consisting of water and bentonite. In the last step, we used the Qualitek-4 software to design experiments, and the Taguchi model was used to investigate the obtained results.
Results
Results show that pH is the most effective parameter in the adsorption process. Interaction of adsorbent concentration with retention time shows the highest …
