"Role of Process intensification in Decarbonisation"

Assoc. Prof. Dr. Tejas Bhatelia,
Curtin University Australia

Without active decarbonisation initiatives such as large-scale implementation of carbon dioxide removal (CDR) technologies, the risk of catastrophic anthropogenic climate change is unavoidable. Despite the fact, that in 2020 the global emission was reduced by about 7% from its previous year, it is well known that this reduction was only temporary. CDR technologies at large scale will thus play a pivotal role in achieving any practical decarbonisation goals and establishing a "Circular Economy". However, the implementation of CDR technologies is facing unprecedented number of techno-economic challenges. To overcome these techno-economic barriers, process equipment needs to achieve efficiencies that are of several order of magnitude better than the current state of the art.

Process intensification tools provide an opportunity and a pathway to accelerate implementation fo large-scale CDR technologies to achieve a decarbonised economy. A/Prof Bhatelia leads the Process Intensification and Innovation group in the Chemical Engineering Discipline of WA School of Mines Minerals and Chemical Engineering and has been working on developing such intensified solution for lower and negative carbon processes.

He commenced his research career 14 years ago and has made significant contributions to the field of Gas processing, Carbon Capture and utilisation, Catalytic Reaction Engineering and Process intensification.

His work in understanding the reaction kinetics of complex heterogeneous catalytic reactions for gas processing is one of the most highly cited papers in this area in the past five years. Recently, he has developed the lowest CO2 footprint process for Methanol production. He has extensively worked on the application of additive manufacturing (3D printing) for process intensification in chemical and processing applications. He was one of the first researchers to apply chemical engineering principles to design 3D printed reactors, flow distributors, multiphase contactors, and mixers for chemical and processing engineering applications. His approach was highly unique and brought a considerable paradigm shift in the way chemical and processing equipment are designed and developed.

In addition, to his substantial publication track record, he holds four international patents and is in process of commercialising two technologies that have direct application in decarbonisation and H economy. Some examples that have quantifiable benefits to clean energy processing industries and their applications include:

  • Development of the super capacity (gas-liquid contactor) structured packing – SpiroPak for applications such as:
  • Carbon capture
  • Direct Air Capture
  • General mass transfer applications
  • Novel isothermal reactor for:
  • Methanol synthesis
  • CO2 Hydrogenation
  • Ammonia synthesis
  • Highly uniform and ultra-low pressure loss fractal flow distributor for:
  • Catalytic reformer
  • Highly efficient burner for the clean burning fuel
  • Liquid-Liquid extractor

A/Prof Bhatelia is a theme leader in an ARC-IRTH hub on Carbon utilization and recycling which is industry driven hub with over 15 national and global industrial partners and five universities established to translate the research outcomes into commercial outcomes. A/Prof Bhatelia research is driven by his passion to make this planet sustainable for future generations.
