Measurement and control aspect of pH using inductively coupled with bidirectional Memosens technology in flue gas desulfurization process White Paper CP971C pH measurement and control in a power utility is an integral part of process. The scrubber efficiency is highlydependent on the pH. Numerous opportunities were revealed for saving time, as well as the cost and materials in power plants. In afossil fuel power plant, the chemical energy stored in coal, oil, natural gas, shale oil, oxygen and air is converted into thermal, mechanical and finally into electrical energy. In other words, water is heated to steam, which spins a steam turbine. The steam turbine drives an electrical generator.
