Centrifugal Compressor with UtilitiesThis complete Centrifugal Compressor with Utilities simulator allows trainees to operate a steam turbine powered compressor. A process gas is put through the compressor and sent off as a product at its new pressure. This simulator includes the control of both lube oil as well as seal oil and both must be commissioned in the start up procedure. The system includes a set of logic interlocks which will cause the turbine or compressor trip at various conditions.

Distillation TowerA binary distillation column, the system is designed to separate a pentane-hexane stream. A seven-tray tower provides fractionation with boil-up provided by a kettle-type reboiler. The overhead system includes a total condenser and an overhead receiver.The bottoms stream is put through an exchanger to preheat the feed flow to make the process more efficient. The program includes a Dynamic Profitability Analysis schematic which allows trainees to track profit and losses while operating the Column. Major credits are the Overhead and Bottoms product, major debits are the cost of the Feed Stream, Steam Usage, and penalties for Off-Spec Product.

Heat ExchangerHeat Exchangers are used to heat one process stream while cooling another stream. In this particular case, the heat exchanger heats a stream of cold water using hot Dowtherm liquid. The Heat Exchanger consists of bundles of tubes, and a shell which surrounds the tubes. Fluid pass through each side of the exchanger in order to transfer heat between them. In this simulation, the cold water to be heated is circulated through the shell side of the exchanger, and the Dowtherm flows through the tube side.

Basic Combined Cycle Power PlantA gas turbine burns fuel gas or oil in the presence of a steam/air mixture to provide the driving force to rotate the turbine. Air is drawn into the air compression section of the turbine where it is compressed before entering the combustion section. The fuel, when burned expands to provide the energy required to rotate the turbine. The hot gasses from the turbine go to a Waste Heat Boiler where they are used to generate steam. The steam generated in the WHB is then routed to either a steam header or steam turbine. The latter drives a Steam Turbine which in turn drives another synchronous generator. The Gas Turbine generate 17 MW, and the Steam Turbine 3 MW, making the Combined Cycle as 20 MW plant.

Flash DrumOften utilized as a "warm-up" for our Distillation Simulator, a Flash Drum separates a binary feed made up of butane and hexane. The Feed is under flow control and the temperature is controlled with a hot oil exchanger. The temperature controller and overhead pressure controller determine the compositions of the overhead and bottoms streams. A mass balance of the two components is displayed in mass per time units to allow trainees to develop a clear understanding of mass balance. A Virtual Reality Outside Operator accompanies the program.

Pump & ValveWater enters a series of tanks in a unit that features feed, level and pressure controllers. Specifically, the pressure on each tank is controlled using a split-range controller utilizing a nitrogen blanket, and vent valve. The first tank in the system features a level controller managing feed entering the tank, while the second tank in the system has a level controller managing feed out of the tank. A series of pumps can be swung during exercises. A Virtual Reality Outside Operator accompanies the program.

LNG LiquefactionThe purpose of the LNG Liquefaction plant is to produce liquefied natural gas (LNG) product from a pre-treated natural gas feed stream. Refrigeration for this process is provided by a propane refrigeration system and a mixed refrigerant (MR) refrigeration system. The four-level propane refrigeration system provides chilling of the natural gas stream and the MR system. The pre-cooled natural gas is sent into the Main Cryogenic Heat Exchanger (MCHE) and is liquefied and subcooled using the MR system. The natural gas feed leaves the system as LNG and fuel gas.

Multiple Effect DesalinationThe Multiple Effect Desalination process runs seawater through a chain of three "effects" to remove salt from the input. The two streams leaving the system are a saltier brine flow, and a freshwater product. This MED process uses distillation principles to remove salt from the seawater in these jacketed vessels. An external steam flow is used to heat the first effect, and this energy is recovered to heat the downstream vessels as well. Trainees will track temperature, pressure and concentration profiles across the multiple effects. A Virtual Reality Outside Operator accompanies this program.

Reverse Osmosis Desalination
The Reverse Osmosis Desalination process brings a flow of seawater first through a multimedia filter to remove any large impurities such as seaweed or sand. The seawater is then sent through a pair of high pressure pumps which force the flow though a membrane to remove salt from the water. The saltier brine flow is rejected and a "freshwater" product with low salt content is collected. The amount of salt in the permeate is measured with a conductivity reading on the outlet side of the membrane. A series of block valves make up a flush system which allows cleaning of both the filter and membrane.
