Abstract
A process cooling water (PCW) system and method for an iron or steelmaking application, the PCW system and method including: sampling a plurality of characteristics of PCW using a plurality of sensors; calculating one or more of Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI) based on the plurality of characteristics using a LSI/RSI measurement unit coupled to the plurality of sensors; and injecting one or more anti-scalant chemicals into the PCW responsive to the calculated one or more of the LSI and the RSI in real time using an anti-scalant injection system to thereby control scale formation in the PCW.
Claims15
A process cooling water (PCW) system for an iron or steelmaking application, the PCW system comprising:
- a plurality of sensors operable for sampling a plurality of characteristics of PCW;
- a Langelier Saturation Index (LSI)/Ryznar Stability Index (RSI) measurement unit coupled to the plurality of sensors and operable for calculating one or more of LSI and RSI based on the plurality of characteristics;
- and
- an anti-scalant injection system operable for injecting one or more anti-scalant chemicals into the PCW responsive to the calculated one or more of the LSI and the RSI in real time to thereby control scale formation in the PCW.
A process cooling water (PCW) method for an iron or steelmaking application, the PCW method comprising:
- sampling a plurality of characteristics of PCW using a plurality of sensors;
- calculating one or more of Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI) based on the plurality of characteristics using a LSI/RSI measurement unit coupled to the plurality of sensors;
- and
- injecting one or more anti-sealant chemicals into the PCW responsive to the calculated one or more of the LSI and the RSI in real time using an anti-sealant injection system to thereby control scale formation in the PCW.
A non-transitory computer-readable medium stored in a memory and executed by a processor to execute process cooling water (PCW) method steps for an iron or steelmaking application, the steps comprising:
- sampling a plurality of characteristics of PCW using a plurality of sensors;
- calculating one or more of Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI) based on the plurality of characteristics using a LSI/RSI measurement unit coupled to the plurality of sensors;
- and
- injecting one or more anti-scalant chemicals into the PCW responsive to the calculated one or more of the LSI and the RSI in real time using an anti-scalant injection system to thereby control scale formation in the PCW.
