Contribution to the automatization of a hydrochloric acid desorption pilot

This academic engineering study addresses the automatization of a semi-industrial pilot used in a hydrochloric acid desorption unit. As the control normally requires a staff of fifteen agents, this study aimed at reducing this number, at increasing the installation reliability (with respect to the hardware as well as to acid quality). Thus, the author reports the study of the process (operation principle, desorption station, concentration/de-concentration loop, vapour central unit, acidification), describes the various components of the instrumentation and regulation chains (detectors, recorders, regulators, adjustment vane, instrumentation technology, regulation chains), describes modifications brought to the instrumentation (to perform measurements and recordings, remote control), and reports the various regulation chains (powers, pressure).
