Aspen HYSYS Petroleum Refining HCR Modeling Tool

For a review and comparison on HCR reactor models, please see the study by Ancheyta et al. [10], and for a review of kinetic modeling of large-scale reaction systems through lumping, please refer to the study by Ho [11], 

The objective of this chapter is to develop, validate, and apply a methodology for the predictive process modeling of large-scale of integrated refinery reaction and fractionation systems from plant data. In particular, we model two commercial HCR units in the Asia Pacific. Medium-pressure HCR (MP HCR) unit processes 1 million tons feedstock per year with a reactor pressure of 11.5-12.5 MPa, while high-pressure HCR (HP HCR) unitprocesses 2 miUion tons offeedstock per year with a reactor pressure of 14.5-15.0 MPa.

In the literature, there are two approaches to developing the lumped kinetic compositions of the feedstock forward and backward. The forward approach 

For example, the user can change the sulfur lump distribution of selected feed fingerprint manually to ensure that the distribution of hindered and nonhindered sulfur compounds matches the plant measurement.
