AI Technical Summary
Technical Problem
Silica scale adheres to various parts of plant systems, necessitating large-scale, labor-intensive mechanical removal after chemical treatment, requiring extended shutdowns.
Method used
A silica scale modifying agent containing a silane coupling agent, such as 3-glycidoxypropyltrimethoxysilane, is introduced into the fluid circulation system to modify the silica scale's chemical structure, weakening interatomic bonding forces and facilitating easier removal during normal operation.
Benefits of technology
The agent allows for efficient silica scale removal without extensive mechanical work, reducing shutdown times and labor, by modifying the silica scale's chemical structure during adhesion and growth, making it easier to peel off.

Abstract
To provide a silica scale modifier to facilitate silica scale removal.SOLUTION: A silica scale modifier contains a silane coupling agent. A geothermal power generation system includes: a gas-liquid separator 2 that separates a geothermal fluid pumped from a production well 6 into gas and liquid components; a turbine 3 located at the rear of the gas-liquid separator and rotatable by the gas component separated in the gas-liquid separator; piping that delivers the liquid component separated in the gas-liquid separator to a reduction well 7; and an injection device 1 that injects the silica scale modifier into the geothermal fluid.SELECTED DRAWING: Figure 1
