Reforming furnaces are special process furnaces used to generate pure hydrogen gas from a hydrocarbon feed gas, such as methane.

In this process, raw maple syrup is heated by steam to evaporate water and make it more concentrated. An analytical

Since the outlet temperature of a heat exchanger can only change if there is an imbalance of inlet and outlet

Since liquid level can only change in a vessel if there is an imbalance of inlet and outlet flow rates,

This paint mixing system mixes (clear) base and (colored) pigment to achieve the desired coloring, according to the ratio setpoint:

PLC and DCS control systems Wiring Diagrams for Digital Input (DI), Digital Output (DO), Analog Input (AI), and Analog Output (AO) signals.

The ratio between base flow and pigment flow in this paint-mixing control system is not fixed. Rather, it comes from
