    Abstract: A thermowell for a fixed-bed reactor which has a vertical spine portion, and multiple spider portions spaced along the spine portion. At least one thermocouple and preferable a plurality of thermocouples are located in each arm of the spider portions with thermocouple leads extending upwardly through the spine portion to a monitor outside of the reactor. The thermowell is constructed in the reactor while loading the catalyst by first positioning the spine portion in the reactor, and then fabricating a spider portion at the lowermost level of the spine portion with at least one thermocouple in each arm of the spider portion and thermocouple leads extending through the arms and upwardly through the spine portion. Catalyst is then added to the reactor to cover the spider portion at the lowermost level. At each successive level, repeating the steps of fabricating another spider portion, and of adding catalyst to cover the spider portion.

    Abstract: A QUICK AND RELATIVELY INEXPENSIVE METHOD FOR FILLING VERTICAL PROCESS VESSELS, FOR INSTANCE, REACTORS OR PACKED TOWERS, WITH PARTICULATE MATERIAL SUCH AS CATALYST OR OTHER PACKING, WHILE PREVENTING CONTAMINATION AND DAMAGING THEREOF. A SPECIAL FLEXIBLE BAG WITH A BOTTOM SEAL WHICH MAY BE OPENED BY MEANS OF A RELEASE LINE IS FILLED WITH THE MATERIAL AND THEN GENTLY LOWERED INTO THE VESSEL BY MEANS OF AN ELEVATOR ATTACHED TO THE UPPER PORTION OF THE BAG. THE BOTTOM SEAL IS THEN OPENED BY PULLING UPON THE RELEASE LINE, PERMITTING THE CONTAINED MATERIAL TO DROP GENTLY INTO THE VESSEL. THE BAG IS RETRIEVED BY PULLING UP ON THE ELEVATOR LINE, AND THE PROCESS IS REPEATED UNTIL THE VESSEL IS FILLED TO THE DESIRED LEVEL.

    Abstract: The present invention provides a process for loading ceramic spheres into a vertical reactor. The process comprises introducing into the reactor along a substantial height thereof a feeding pipe that is opened at its bottom part. According to the invention, no physical device or air-supplying conduit is present inside the inner section of the feeding pipe. The process allows for rapid, safe and efficient loading, without breakage of the particles.
