USE OF PSA FOR DESIGN OF EMERGENCY MITIGATION SYSTEMS IN A HYDROGEN PRODUCTION PLANT
Figure 3: Isolation system EAS-200
Once the solution exits the homogenisation tank, the default pump (other pump in standby) will
send the solution through the main line to the sprinklers located in the sulphuric acid decomposition
section. This system is not considered successful if the mixing of water and carbonate does not take
place, or there is no flow to the sprinklers.
The electric back-up to this process is independent of that of the isolation system, the diesel
generator is a different brand and capacity, therefore common cause failure will not be considered
(Fullwood, 2000). The activation of the neutralisation process is carried out by the emergency system
EAS-200, and leak detectors AI201 and AI202, as shown in Figure 4.
