CATnap catalyst removal technology by Cat Tech

CATNap® patented technology eliminates the need for working in dangerous nitrogen filled environment typically created in Hydrotreaters and Hydrocrackers whilst routine maintenance is carried out. Whilst standard industry practice has historically dictated that the removal of self-heating and pyrophoric catalyst means an inert atmosphere is a must, this is no longer the case. Instead a proprietary CATnap® chemical applied as part of a modified reactor shutdown procedure coats the catalyst surfaces supressing self-heating and toxic/pyrophoric dust allowing your catalyst to be safely unloaded in air.

CATnap® benefits are not just limited to safety however, through its application; we have a proven record in helping refiners significantly reduce their shutdown timeline on critical path reactors and with that benefitted from substantial associated cost savings. The passivation process mitigates high LEL's, eliminates the hot hydrogen strip and allows quicker cooling of the reactors as the process takes advantage of cooling under oil recycle. This is in addition to the substantial savings in Nitrogen costs.

To date CATnap® has been applied to over 350 units worldwide and through re-engineering and process development we can ensure that your catalyst unload is first and foremost the safest possible option and the most cost effective. Skimming or full catalyst removal, CATnap® allows you to exploit a combination of significant risk and cost reduction measures whilst ensuring the catalyst remains fully regenerable.
