SIM 4200 Amine System

Model Description

The model contains a fully functional ESD (emergency shut-down) system including start-up overrides, inhibits, intertrips and executive action. The ESD is displayed within an industry standard type cause and effect matrix.

Natural Gas feedstock has adjustable CO2 content.

The model contains fully functional examples of amine absorption and amine regeneration columns with re-boilers and heat recovery systems.

The process streams have component analysis points so the effect of differing process conditions can be investigated and monitored.

All pump systems contain duty standby pumps for switch-over and stabilisation.

On a modern PC the model can run faster than real-time reducing the time spent waiting for things to happen.

The model can be fully shut-down and restarted and a black start (empty and nitrogen purged) second start is provided to allow start up training.

Learning Areas

• Introduction to Natural gas sweetening system management and operations.
• Introduction to the absorption of acidic components of raw natural gas using an amine absorber.
• Introduction to the removal of acidic components from the amine system.
• Builds on basic ESD (emergency shut-down) system knowledge with a fully functional, graphical, multi page cause and effect system.
• Shows process interaction between columns, building on the idea that no unit operation exists in isolation and also builds on distillation column understanding.
• When used with a trainer the model can test a trainee’s reaction to external process changes, alarm handling, fault finding, and resolution.
• The effect of different feedstock can be investigated and the process can be optimised by a trainee.
