For some models adsorption or storage is important. For example, oxygen storage is important in a 3-way catalysis, a catalyst may contain a hydrocarbon storage component for improved low-temperature performance, and ammonia storage is important for ammonia SCR (selective catalytic reduction). Clearly, this sort of behaviour needs to be included in the final model. The nature of the measurements depends on the exact system being studied and will be discussed in more detail later. Suffice to say, from measurements at steady state, the heats of adsorption and coefficients of... 

Further functionality can be added to the DOC by the incorporation of a hydrocarbon storage component, typically a zeolite, to the catalyst formulation. This serves to trap hydrocarbon in the exhaust from engine start-up, when the temperature of the catalyst is too low for oxidation reactions to proceed at the required rate. This stored hydrocarbon is later released as the temperature increases, ideally at a temperature at which oxidation to C02 can occur. The overall result is that hydrocarbon slip is reduced even when the system is cold at start up, resulting in much lower total emissions over the drive cycle. 

It is thus necessary to include a description of the thermodynamics and kinetics of hydrocarbon storage in a model of such a DOC. Typically, we have based this on hydrocarbon breakthrough experiments. In this experiment, hydrocarbon in an inert carrier is passed over an outgassed DOC core sample.

For zone classification process flow diagram (PFD), P IDs, cause and effect diagrams, area classification of plants for electrical apparatus (ref. Chapter X) and plot plans are required documents for zone classification. In process plants, different areas have different leakage or release hazards, for example, hydrocarbon storage area will have flammable gas release whereas sulfur recovery units pose a H2S toxic gas hazard. So, it is imperative to define and segregate the zones from each other.

Based on the failure rate, the risk tolerable frequency can be estimated. Such things are possible in simpler cases, as given in the example later. Referring to the storage tank example as shown in Fig. VII/1.4 1 (or Fig. Vlll/1.2.2-1), let this hydrocarbon storage area be manned 2 h per shift, that is, 6 h a day. On account of overpressure there may be leak that could cause an explosion and (say) out of 15 such leaks there will be one explosion causing a fatality. Analysis indicates that every 6 years there is an explosion. Let the tolerable frequency of explosion be 10. The required PFD can be found by direct calculation ...
