Nanobubbles as Corrosion and Scale Inhibitor

Abstract

Geothermal resources with lower temperatures present many successful industrial applications; however, they all have a common problem of scaling and/or corrosion. The cost to mitigate the problems with scaling and corrosion should not be underestimated so that the operators can better plan for the maintenance. It is also increasingly becoming more difficult to justify using chemical agents to prevent these problems because of the elevated level of environmental concerns. The authors have started to investigate environmentally friendly and cost-effective ways to solve these problems. In this presentation, we will share our preliminary experimental results on nanobubble usage as a corrosion inhibitor. We will also share our fieldwork at a small town in Kyushu, Japan where our endeavor on this emerging technology is strongly supported.
