Process Flow Diagram

Simulation of the Plant Section 1 of the process “almost done”

Simulation of the Plant Feed stream (#1): Total flow rate is based on the annual production of 500,000 tons of Propylene Based on the production of Sadara (a neighboring plant) which produces 400,000 tons annually(26) Temperature & Pressure(27)

Simulation of the Plant Heat Exchanger (E-101): Pressure drop of 0.1 bar (both shell and tube side)(Turton) Outlet temperature(27) U value(Turton) High Pressure Steam (41 barg, 254 oC)(Turton)

Simulation of the Plant Heat Exchanger E-102: Currently modeled as a Heater block Temperature of outlet stream(27) Pressure Drop(Turton)

Simulation of the Plant DME Reactor R-101: Temperature & Pressure(27) Equilibrium Reactor

Simulation of the Plant MTP Reactor R-102: Temperature & Pressure(27) Stoichiometry Reactor Chemical Reactions(28)

Problems and Concerns Encountered MTP Reactor problems: Reaction kinetics are incomplete Too many side-reactions Plug flow reactor cannot be used

Problems and Concerns Encountered MTP Reactor concerns: R-stoic is used since selectivity and total convergence is available Distributing the convergence on the reactions and balancing the total outcome Some products are being re-consumed as reactants in some side reactions
