MOSCOW (MRC) -- Axens has been selected to supply the technologies for the acid gas removal unit (HySWEETTM) and the sulfur recovery unit (SmartSulf) of the Albright sour gas processing plant to be constructed by CSV Midstream Solutions Corp. in Alberta, Canada, said Hydrocarbonengineering.
For the acid gas removal unit, Axens licensed the HySWEET technology in order to process 152 million ft3/d of natural gas. HySWEET is a hybrid process for simultaneous removal of mercaptans and acid gases from natural gas, developed by TotalEnergies and commercialised by Axens.
For the sulfur recovery unit, Axens licensed the SmartSulf technology to handle the acid gas from the HySWEET in order to remove 370 tpd of sulfur and achieve a sulfur recovery of 99.5+%. Axens' scope of work includes the supply of the process design packages, the supply of the specific equipment for the SmartSulf unit as well as full services from plant personnel training to unit start-up.
Both units are now under process design phase and commissioning is expected for the end of 2024.
“CSV thoroughly evaluated a number of processing technology options prior to selecting the HySWEET and SmartSulf processes for our Albright sour gas processing plant. Throughout the evaluation, Axens and TotalEnergies were exceptionally cooperative and transparent, providing CSV with the confidence that the technologies were the right choice for our facility. Further to that, the benefit of working with one process licensor for both technologies provides significant synergies that allow for a streamlined project execution. The HySWEET technology’s ability to minimise hydrocarbon co-absorption will bring operational benefits to our sulfur recovery unit, while the SmartSulf unit will provide best-in-class sulfur recovery metrics with a smaller footprint and reduced CAPEX and OPEX”, says Dan Cote, CSV’s Director, Projects.
“We are proud of having been selected by CSV Midstream Solutions for this project. The specific Axens’ process scheme combining a HySWEET unit followed by a SmartSulf unit provides a very competitive solution in terms of simplicity, CAPEX and OPEX as well as emissions mitigation for the Albright sour gas processing plant. We are confident that this is the start of a great collaboration between CSV, TotalEnergies and Axens” says Jacques Rault, Axens’ Executive VP Technology & Technical Support.
“This commercial success crowns the development of the HySWEET technology. This solvent relies on a hybrid formulation developed by TotalEnergies R&D to simultaneously remove H2S, CO2 and organic sulfur species such as mercaptans while reducing the carbon footprint of the gas treatment. It illustrates TotalEnergies' expertise and commitment to finding technical solutions that reduce the environmental impact of gas as an energy of transition” says Marie-Noelle Semeria, TotalEnergies's Chief Technology Officer.
We remind, Axens has acquired stakes in the BioTJet project, the aim of which is to build and operate the largest European Sustainable Aviation Fuel (SAF) production unit using the Fischer-Tropsch process, relying on the BioTfueL technology. This unit will be built in France and will be started up by 2027.
