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?What's an ORC Geothermal Power Plant?
A dynamic simulation model is developed in VMG Dynamic Simulation software. As you see the cycle is fairly simple. The hot geothermal water boils the working fluid into vapor to drive the expander to produce power. After the refrigerant is condensed in the condenser, it is pumped back to the evaporator through the receiver.In this particular example, we want to see what's the optimum superheat temperature entering the expander. Currently the hot water pump is in manual mode, thus it will always pumps the same amount of hot geothermal water in the system.
ORC Power Plant Dynamic Optimization
Currently the super heat temperature is 30 F, the expander is producing about 1017 HP.
What's going to happen if you change the super heat to 20 F instead? Great, we are now producing about 1057 HP.
How about 10 F, we are making about 1075 HP.
How about 5 F? It looks like we are still making the same power.
To make sure the expander always have a dry inlet gas, we are going to set super heat at 10 F.
Benefits of VMGSim Dynamic Simulation
With VMG Dynamic Simulation, you can virtually operate the plant just like the operator sits in front of the HMI machine. You can test out all your crazy ideas without worrying about a shutdown of the real plant.Thanks for watching this video. It is brought to you by Guofu Chen.
