Spesialized Chlor-Alkali Electrolysis in OTS (Green Hydrogen Dynamic Simulator)

BPT's tailor-made dynamic simulator model of Chlor-Alkali electrolysis has been selected for use in an Operator Training Simulator (OTS) for a major customer in Asia Pacific. Dynamic scenarios like start-up, shutdown and load changes will be accurately represented, covering both normal as well as abnormal operational scenarios.

"This contract is a testimonial demonstrating our unique and world-leading simulator software for green energy systems", expresses Mr. Spilling, the BPT CEO. "Realistic and efficient training of plant operators in safe and proper operation of green hydrogen facilities is crucial in accelerating the green shift globally".

As a part of this project, BPT specialist will customize the standard alkaline electrolysis model with additional Chlor-Alkali features, branded under the BPT-SimApps simulator software as BPT-ECX-CA.

In this specific OTS, fully dynamic scenarios like start-up, shutdown and load changes will be accurately represented, covering both normal as well as abnormal operational scenarios.

The BPT-ECX software covers both steady state and dynamic simulations with high fidelity and capability to be adjusted to match specific equipment from various manufactures.

The BPT-ECX is a flexible and accurate electrolytic separation cell model that could be seamlessly used together with industry-standard process simulators like HYSYS, UniSim and Petro-SIM. The unit operation works in both steady state and dynamic modes. The electrolysis unit operation application is a part of BPT's comprehensive extensions to process simulators and the first among several green energy focused applications developed, under pilot plant testing as well as in commercial use.

Different type of electrolysis is included in the BPT-ECX:

• PEM (Polymer Electrolyte Membrane electrolysis)
• AEL (Alkaline ElectroLysis)
• SOEC (Solid Oxide Electrolyze Cell)

 

Some of the user parameters are:

• Area and number of cells
• Flexible geometry (vendor specific)
• Electrolysis efficiency and over-potential
• Voltage cell
• Faraday efficiency
• Gas purity
• Heat loss
• Thermal lag

 

The main benefits of BPT-ECX are:

• BPT-ECX facilitates accurate interactive steady state and dynamic simulation of electrolysis plants without the need for process engineers that have specialist knowledge of advanced simulation tools. BPT-ECX is user-friendly.
• BPT-ECX is fitted for standalone models of the electrolysis stack units or in simulation models where electrolysis is a part of a larger plant where the interaction and controllability between the various parts are of crucial importance to validate and improve.
• BPT-ECX enables transfer of experimental data of newly developed electrolysis cell technology into an overall electrolysis plant model to evaluate the new technology and design pilot and industrial plants.
