						Catalyst Loading
		ABOUT US
						SOCK LOADING METHOD Sock Loading involves placing the catalyst into a hopper on the top of the reactor manway and discharging it through a canvas or rubber sock. One end of the sock is attached to the loading hopper discharging pipe and the other end travels to within 3 feet of the catalyst support grate/grid. The loading technician will crimp the sock to restrict free fall of material as he spreads the catalyst evenly and in a random pattern. As the bed level rises the sock is cut to keep the free fall of catalyst to the required distance and the discarded sections are removed from the reactor.

						DENSE LOADING METHOD “Dense Loading” is achieved by a mechanical device that insures a uniform distribution of catalyst throughout the entire diameter of the reactor as the catalyst is being loaded. The catalyst is discharged in a “sprinkling” fashion allowing each piece of material to fall randomly to the catalyst bed ensuring a consistent loading. A dense loading system can increase the loading density by as much as 10-20 percent depending on the type and shape of catalyst that is being loaded. It generally will improve the liquid or gas flow, eliminates catalytic bed settling and generally allow for a longer run cycle in between catalyst replacements. SPECIALIZED LOADING Catalyst Handling also offer multiple tube loading of tubular reactors using machines that will load 10 tubes at a time equally. Multiple machines can also be set up and used to allow the schedules to be dramatically reduced while maintaining high quality. Catalyst Handling has available Unidense technology for the loading of primary reformers. This technology allows for consistent  loading of catalyst into each tube ensuring that all DP’s are within the pre determined range. DENSE PHASE LOADING Catalyst Handling have been using Dense Phase Loading equipment for over 20 years now and have loaded many reactors without the requirement for a crane. This process comes into it's own for loading horizontal vessels, Sulphuric Acid Converters or when high winds and inclement weather are likely to occur. This equipment can be set up with limited access and can be very beneficial to our clients. Loading rates can be up to 525-700 cubic foot/hr (15-20 m3/hr) depending on distance and material to be transported.
