Intensifying boolean matrix concept in modelling cascade liquefaction of natural gas

Technologies for natural gas processing depend on the scope required, composition of the gas, CAPEX and end-use application or utilization. Liquefaction is one of the operations used for the separation of natural before separation into other derivatives. The liquefaction operations that apply cascade models have been used to illustrate its applicability for natural gas processing1. The model is flexible and configuration advanced to different stages – simple, multiple and hybrid cascade models2-4. The Boolean Matrix concept enabled us to: simplify binary representation of complex cycles; apply computer-based algorithms (matrix multiplications, graph theory) and modelling; identified dependencies between cycles; facilitate simulation convergence (e.g., detecting recycle loops before solving), generalize and advanced the cased models to complex configurations. The cascade models configurations presented here conform to the Boolean matrix concept, with its application here being fully described and explained. Overall, the Boolean Matrix concept and the modelling approach have enabled the integration of different cascade models into a single train natural gas processing, which allowed the advanced model to evaluate the impact and contribution of each or combination of cascade models to the entire simulation. Over a hundred modelling and simulation have been done to further test and prove the concept and the data supplied used; each simulation converged and gave satisfactory results. The flexibility, reliability and applicability of this model have now been fully demonstrated.
