Industrial Process Control
Process control improvement saves energy by heating only to the required temperature for the required amount of time. Sloppy tolerances that tend to over-heat product just to be sure the job gets done can also affect product quality. Even well maintained, but old gas trains with linkage controls cannot match today’s digital proportional controls and improved temperature sensors. Controlling the air (oxygen) is also critical to economical and efficient operation. Excess air brings with it a whole bunch of excess nitrogen that does nothing for the process but rob it of value heating energy.
New process controls that use improved valves and sensors to precisely monitor and control a process can result in significant operational savings; often and usually more important, there can be a product quality improvement as well.
