Improve the quality of primary reformer catalyst loading by Unidense technology UNIDENSE TM catalyst loading technology is used for filling primary reformer tubes in ammonia, methanol, hydrogen and other reformer based plants. It results in a high and uniform catalyst density for efficient operation of the primary reformer. UNIDENSE TM is a simple and fast loading technology applicable to tube sizes from 3 to 10” internal diameter. UNIDENSE TM requires no pre-socking of catalyst and no vibration of the reformer tubes. UNIDENSE TM combines being a high quality and fast loading technology. Reloading of tubes is normally avoided, and less catalyst is wasted. UNIDENSE TM principle: Catalyst is filled into the tube and the loading rope is gradually pulled out of the tube as the catalyst layer builds up. The brushes with flexible springs reduce the speed of the catalyst particles so that the breakage is avoided. The catalyst particles are loaded without bridges and unnecessary voids, hence there is no need for vibration. By applying the UNIDENSE TM technology the loading time of the primary reformer can be substantially reduced whilst maintaining high quality loading. Typical loading time for 4” tubes is 8 minutes. UNIDENSE TM technology ensures even gas flow in the tubes, and the pressure drop variation is kept to a minimum. The density will normally be higher than with the ‘sock’-method, resulting in slightly increased, but more even pressure drop, due to better packing. Since there are no extra voids, further settling of the catalyst, and thus pressure drop increase, will be minimal. UNIDENSE TM gives high uniform density along the full length of the tube, decreasing the risk of hot spots and contributing to lower tube wall temperatures and prolonged tube life. UNIDENSE TM technology has been used for loading of all common catalyst types and sizes. Reformer tube designs with varying internal diameter, narrow or wide top section, have successively been loaded.

UNIDENSETM catalyst loadingtechnology is used for filling primaryreformer tubes in ammonia, methanol,hydrogen and other reformer basedplants. It results in a high and uniformcatalyst density for efficient operationof the primary reformer.

UNIDENSETM is a simple and fastloading technology applicable to tubesizes from 3 to 10” internal diameter.UNIDENSETM requires no pre-socking ofcatalyst and no vibration of thereformer tubes.

UNIDENSETM combines being a highquality and fast loading technology.Reloading of tubes is normally avoided,and less catalyst is wasted.

UNIDENSETM principle: Catalyst is filled into the tube and theloading rope is gradually pulled out ofthe tube as the catalyst layer builds up.The brushes with flexible springsreduce the speed of the catalystparticles so that the breakage isavoided. The catalyst particles areloaded without bridges andunnecessary voids, hence there is noneed for vibration.

By applying the UNIDENSETM

technology the loading time of theprimary reformer can be substantiallyreduced whilst maintaining highquality loading. Typical loading timefor 4” tubes is 8 minutes.

UNIDENSETM technology ensures evengas flow in the tubes, and the pressuredrop variation is kept to a minimum.The density will normally be higherthan with the ‘sock’-method, resultingin slightly increased, but more evenpressure drop, due to better packing.

Since there are no extra voids, furthersettling of the catalyst, and thuspressure drop increase, will be minimal. UNIDENSETM gives high uniform densityalong the full length of the tube,decreasing the risk of hot spots andcontributing to lower tube walltemperatures and prolonged tube life.UNIDENSETM technology has been usedfor loading of all common catalysttypes and sizes. Reformer tube designswith varying internal diameter, narrowor wide top section, have successivelybeen loaded.� Loading of catalyst
