Two years after the launch of its new digital Carelflex® service, Arkema has greatly improved the content of its digital platform known as Carelflex® Connect. An intuitive design eases its use, and a private instant messaging service has reinforced communication between the on-site Arkema team and refinery representatives.
Catalyst sulphiding with DMDS and Carelflex® service
For the last 30 years, Arkema has supported the development of DMDS refinery applications by offering a service to safely handle and carefully inject the DMDS, following the procedure of the hydrotreating catalyst manufacturer. A major improvement has also been achieved with the use of in-line H₂S analysers (see previous articles in ERTC newspapers in 2017 & 2018) that address a safety concern on the use of a reactive tube that would otherwise create a potential for exposure to H₂S for workers. Moreover, Arkema’s H₂S analysers offer a continuous H₂S measurement that allows the refinery to anticipate the DMDS flow rate and reactor temperature changes, saving time and significant DMDS volumes.
Why offering a digital Carelflex®service?
A full digital project to meet refinery expectations
As a result, in 2021 Arkema launched a secured and temporary instant messaging service (see Figure 2) for each operation that includes:
- Secured access: a list of users is agreed with the refinery one week before and cancelled two weeks after completion of the operation. Catalyst supplier representatives may be given the same access when requested by the refinery.
- Artificial Intelligence (BOT): The BOT uses the Chat function to send the latest value of DMDS and H₂S concentration data on demand. The refinery team use the BOT to send instructions to the Carelflex team, who acknowledge receipt from their tablets on site. Moreover, any DMDS flow rate change is automatically reported to the refinery team on the Chat by the BOT.
- User-friendly platform: the instant messaging service provider Citadel™ is available through a web page or mobile phone app and can be checked at anytime. Any member of the user group can check the entire Chat at anytime: it enables, for example, any refinery team member to track and understand the history of DMDS flow rate changes and related instructions upon the start of their shift.
Arkema’s H₂S analyser and digital platform greatly improved the efficiency of hydroprocessing units’ start-up sulphiding operations. These elements streamlined the process engineer’s focus and resources on critical unit parameter adjustments. Looking forward to these proven value-adds for future sulphiding operations.
