In this work, an integrated conversion system of coal to ammonia (NH3) is developed with the objectives total energy efficiency maximization and process simplification. The integrates drying, chemical looping hydrogen production, cryogenic nitrogen separation, NH3 synthesis, power generation. Due integration, exergy destruction from each individual process, as well whole system, can be reduced ...

more than half of all hydrocarbon reservoirs are naturally fractured reservoirs (nfrs), in which production forecasting is a complicated function of fluid flow in a fracture-matrix system. modelling of fluid flow in nfrs is challenging due to formation heterogeneity and anisotropy. stress sensitivity and depletion effect on already-complex reservoir permeability add to the sophistication. horiz...
