Solid Phosphoric Acid Catalyst Loading System (Spa-CLS ™)

Solid Phosphoric Acid Catalyst Loading System (Spa-CLS™)The World’s first Automatic Solid Phosphoric Acid Catalyst Loading System for SPA1 and SPA2 Catalysts from TubeMaster®, Inc.. Combining four of our best catalyst loading solutions in a device that delivers speed, quality and value while improving line-of-fire safety for SPA process owners.

Using the patented Outage Loading Equipment (OLE’™) to control catalyst loading using an opening slightly larger than the maximum catalyst pellet dimension, Spa-CLS ™ can load more catalyst in the same volume tube than other methods with improved pressure-drop kurtosis. OLE’ ™, in use since 2005 is engineered to load to the correct outage without vacuuming, thus avoiding wasted catalyst.

Spa-CLS ™ uses OLE’ ™ beneath the patented Just Add Catalyst (JAC™) device. JAC ™ loads catalyst by putting minimal energy into the bridge that forms directly above each tube allowing pellets to enter each tube slowly but overall faster since JAC ™ loads every tube at the same time.

Spa-CLS ™ includes a hopper for catalyst storage and distribution with an option for weatherproofing. The hopper is integrated into a common frame with a screener under vacuum to remove dust and fines. The screen is engineered to be gentle on the most friable catalyst based on modeling using 3D printers and testing in the firm’s Louisville, Kentucky lab. SPA catalyst is loaded by a single operator using a remote control pendant to control catalyst flow through the screener and hose onto the tubesheet. A similar engineered final hose end screen is optional. Spa-CLS ™ uses air logic to cause JAC ™ to do the loading work while the screener incorporates an internal air makeup system to allow dry plant air to displace air vacated by the vacuum thus maintaining low humidity for hydroscopic SPA catalysts making Spa-CLS ™ a great choice for intrinsically safe required locations. Using just the hopper and screener portions the Spa-CLS ™ can load SPA1 catalyst in non-tubular reactors.
