Balls packing

Load it three bed hydrogenation R101 of balls. R101 packed bed (bottom bed) `① discharge tube is removed from the catalyst bed above the reactor internals, so as not to interfere with catalyst loading. www.pxsbaixing.com/? ② balls or equivalents with φ13 full bottom discharge pipe, and then use φ13, φ6 and φ3 balls in three sizes, respectively, will be filled until the chalk mark 3 at the bottom of the bed and leveling. ③ on the ground will be a catalyst in the bag or bucket into the hopper, and then lift the bucket to set up a manhole above the reactor catalyst hopper. ④ in accordance with the requirements of the load figure into the RN-10B catalyst layer of the first three. Each one meter to stop charging to check the loading effect, and raked again. In the last bed check, in the middle of the bed distributor trays or less 400 mm and 200 mm at a number of chalk mark made two to help do the bed 3 "topped." ⑤ In the "topping" job, the first catalyst loading area adjacent to the reactor wall, because it is the most difficult to reach areas. Fill out the center portion of the bed are aligned and distributor tray at the following 400mm, refill φ6 balls 200mm, and the distribution of bed leveling 200mm disc at the following. ";. ⑥ When the bottom of the bed load is completed, clean the dust from the internal components of the catalyst has filled a good bed to check on the catalyst support in the catalyst filling the screen to make sure the process is not damaged and then install the manhole cover again. Assembly middle of the bed of the inner member, by relying on the vacuum suction catalyst catalyst discharge tube into the catalyst bed. When each subsequent reactor catalyst bed packed, these steps will be repeated again and again from the pipes 2) filling the first R101 Two beds removed from the reactor bed catalyst discharge more internal member communication pipe to prevent interference catalyst loading. ② balls or equivalents with φ3 filling catalyst discharge communication pipe. ③ along the catalyst support screen above about 100mm (200mm) in the wall of the bed 2 as the chalk mark. ④ sieve catalyst support in the top were filled with two φ6, φ3 balls and leveling. ⑤ in accordance with the requirements of the load diagram RN-10B catalyst loading to the bed according to bed 3 loading method step loading method 4) were described. ⑥ at the top of the filling, according to the bed 3 loading method in step 5) is mounted, and complete the job. 3) R101 is packed the first bed. ① removed from the reactor bed catalyst discharge more internal member communication pipe to prevent interference catalyst loading. ② balls or equivalents with φ3 filling catalyst discharge communication pipe. ③ along the catalyst support screen greater than about 100mm (200mm) in the wall of the first bed as chalk mark. ④ sieve catalyst support in the top were filled with two φ6, φ3 balls and leveling. 0 d8 C7 @, J & h4 {⑤ accordance with the loading the figure requested RN-10B catalyst loaded into the bed. conducted in accordance with bed 3 loading method step loading method 4) above. ⑥ at the top of the filling, according to the bed 3 loading method step 5 ) were filled and complete the job. After ⑦ when the top of the first catalyst bed Bahrain, then loaded protective agent 10B (455mm). In the protective agent filled balls φ13 of the above. ⑧ final installation trim import distributor, and finally cover large reactor manhole cover, connected at the top of the line. balls hydrogenation unit is generally packed in two positions catalyst bed lower and upper catalyst bed. packed in the lower portion of the catalyst bed in order to prevent the catalyst balls flowing outlet collector aperture or screen grid plate and arranged to protect the catalyst bed is relatively stable.
