Are You Leaving Money on the Table Without Optimizing Your ORC Power Plant?

You Want to Produce More Power via Your Geothermal ORC Power Plant?

Geothermal water is even more precious than the oil! Why? Because both of them use the same drilling process, yet water value is a lot less than the oil. Some companies use the geothermal water to produce electricity through an Organic Rankine Cycle (ORC). It costs so much to drill for the geothermal hot water. You surely want to maximize the potential of the hot geothermal water, don't you?

How Do You Control Your Gas Processing Mechanically Refrigerated Unit (MRU)?

Are you confident with your process control?

You modeled a steady state mechanically refrigerated gas processing unit, and then you created P&ID by adding all the control logics. Are you confident your closed refrigeration loop is going to work as you expect?

Dynamic Simulation is the solution.

The best way to verify your control logic is to build a dynamic simulation. This particular model is built in VMGSim Dynamic.

Do You Really Know How Your PRICO LNG Plant Performs at Off-Design Conditions?

You designed your PRICO LNG plant, you know what it is supposed to do at the design condition. Do you really know how it performs at off design conditions?

Two rate based process simulation models are developed by Guofu Chen. One is a fast rating method utilizing UA, while the other method embeds Aspen EDR to rigorously model the performance of the plate-fin heat exchangers.

Is Your Slug Catcher Big Enough for Pipeline Pigging?

The Challenge

Pipeline pigging and slug catcher modeling have been a very difficult challenge for long long time. Now thanks to VMG, we can model pipeline pigging very easily in VMG Dynamic Simulation.

Do You Test Process Control and Cause & Effect via Dynamic Simulation?

Problems with Steady State Simulation

Steady state simulation is very good for designing a plant. However, when it comes to operation, there are so many questions a steady state simulation simply can't answer. Two typical questions are:

• Is my process control going to work?
• Does my cause and effect diagram really prevent me from any danger?

Guofu Completed VMGSim Dynamic Simulation Training by VMG

Guofu Chen has successfully completed "Dynamic Simulation with VMGSim" in Houston on July 16-17, 2015.
