The Mimic dynamic simulation application package for LNG plants provides a high performance solution for operator training and control system optimization.
The virtual LNG plant package provides the complete environment for control system optimization and is an effective tool for teaching process and control engineers the use and design of process controls in LNG plants.
Mimic Dynamic Simulation allows LNG Plant operations managers to:
This package uses Mimic Advanced Modeling Objects for dynamic, real-time, first principles modeling. The Mimic Advanced Modeling Objects are part of the Mimic Advanced Modeling Objects License that adds sophisticated modeling objects into the Mimic Simulation Studio modeling palette. These Objects can be used on Mimic systems for application software testing or operator training. The Mimic Advanced Modeling Objects License provides:
In Mimic Simulation Studio, process models using these objects can be integrated with any other models or Mimic dynamic modeling blocks. All modeling objects in Mimic are IEC1131 function blocks. Models can be built off-line and then viewed executing on-line with real-time values from the Mimic Simulation engine. The process of going from off-line model building to on-line model tuning is fast and intuitive.
Mimic Dynamic Simulation for LNG plants provides accurate, real-time I/O updates to the off-line control system. The simulation consists of a collection of real-time, dynamic, first principles unit operation models configured to respond closely to the actual operations of the user’s facility. The scope of the simulation can be easily configured to meet the user’s and plant design’s needs.
While there are a variety of LNG processes, in general a complete solution for a LNG facility will include a dynamic simulation for the following process areas:
The most complex of these operations being natural gas liquefaction due to the involved heat exchange operations taking place between the natural gas and the refrigerant in and around the cold box.
The pre-cooler and cold box are rigorously modeled using stacked Mimic Vessel VLE objects for each bundle. Models include the following functionality:
In addition to the use of Mimic Vessel VLE objects to serve as flash drums, these models are supplemented with a dynamic, real-time pressure-flow network along with appropriate energy balances for each Mimic Compressor and Dynamic Heat Exchanger object.
The Mimic Component Studio instructor station graphic allows full control of the dynamic LNG Plant simulation with a dynamic Block Flow Diagram view of the major plant units and easy-to-use instructor controls. The following instructor controls are included:
Mimic Dynamic Simulation Application Packages provide an excellent return on investment for plants training and operation budgets. Unlike other dynamic simulation technologies, they are:
The Virtual LNG Plant is an excellent platform for operators of liquefied natural gas production facilities to optimize their automation platform and address their operator training needs. Mimic Simulation Software is an enabling technology that addresses the needs of the energy industry process operators (see the Business Case for the Virtual Plant).
