Solid Waste Management

RSI SIMCON develops dynamic simulators in the field of waste-to-energy.

High Fidelity simulation projects include:

• Combustion of domestic solid wastes in a furnace with a dedicated grid.
• Production of superheated steam in heat recovery steam generator.
• Combustion of domestic solid wastes production of superheated steam in a furnace – boiler scheme.
• Energy conversion into electricity and heating within a Water & Steam Cycle including steam turbines, condensers, de-aerators, heat exchangers.
• Flue gas treatment via dry, semi-wet and wet processes including reactors, scrubbers, bag-house, filters, etc.
• Water management.
• Utility water.
• Potable water system including iron removal filters and activated carbon filters to remove suspended particles, free chlorine and organics – automatic backwash sequences.
• Demineralization section including cation exchanger, decarbonator and anion exchanger - operation/regeneration sequences.

Energy Saving

RSI SIMCON has all the tools (process and control unit operations, control strategy) to develop highly integrated processes.

The 'DEE' Simulator simulates the distillation section of a Highly Integrated Process.

The objective of the simulator is to train operators to manage and control the Crude Switch operation.

Distillation process overview

The simulator is implemented with a special crude thermodynamic characterization and a high fidelity control strategy. The process with energy integration has a relatively small feed furnace compared with the distillation column capacity, and a large number of heat exchangers. At the same time, the process generates LP/MP steam in a boiler.

The Crude Switch model includes the atmospheric distillation, vacuum distillation, gasoline stabilization and separation, water treatment, gas plant and steam facilities, including columns, heat exchangers, air coolers, separators, boilers, furnaces, furnace tube exchangers, controlled by around 400 PID control loops.

The model was tuned on two extreme crude oils Heat & Material Balances, one light oil and one heavy oil obtained by test runs.

INDISS High Fidelity Emulated Real Time Dynamic Model is so realistic that an operator with 20 years of experience could not differentiate between the simulator and the real process. The simulator is also used for engineering purposes.

More details on this project are given in the documentation published in the proceedings of the ERTC Computing Conference, London (May, 2004) and ARTC Asset Maximisation Conference, Singapore (February, 2005) in which RSI SIMCON participated.
