Effect of Change in Plant Capacity towards Controllability of Biohydrogen Production Plant from Biomass

Table 2

List of controlled variables and the chosen controller type.

Controlled variables	Controller types	Reasons
Temperature inside gasifier	MPC	Energy conversion and maximizing reaction inside the gasifier
Temperature inside char combustor	PI	This process does not directly affect the amount of H2 produced
Temperature of “flue gas out” stream	PI	This process is simple and does not directly affect the amount of H2 produced
Temperature of “gas out SMR” stream	MPC	Energy conversion and maximizing reaction inside the SMR
Temperature of “gas to WGS” stream	MPC	Energy conversion and maximizing reaction inside the WGS reactor
