Monitoring device installation method and apparatus

摘要

A method for installing a monitoring device with the simultaneous loading of a particulate catalyst into a vertical catalyst tube includes (i) introducing a monitoring device into the tube, (ii) introducing monitoring device alignment apparatus into the tube, (iii) introducing catalyst loading apparatus into the tube, (iv) loading catalyst particles into the top of the tube whereinafter they contact said catalyst loading apparatus as they pass down the tube, forming a uniform bed of catalyst beneath said catalyst loading apparatus and alignment apparatus and around said monitoring device, and (v) simultaneously removing the catalyst loading apparatus and alignment apparatus from the catalyst tube in timed relationship to the catalyst loading. The monitoring device alignment apparatus includes a ring member and two or more spacing members affixed to the ring member such that the ring member and the monitoring device are centrally positioned within the tube.

1. A method for installing a monitoring device with the simultaneous loading of a particulate catalyst into a vertical catalyst tube comprising:
(i) introducing a monitoring device into the tube, (ii) introducing a monitoring device alignment apparatus into the tube, (iii) introducing a catalyst loading apparatus into the tube, (iv) loading catalyst particles into the top of the tube whereinafter the catalyst particles contact said catalyst loading apparatus as the catalyst particles pass down the tube, forming a uniform bed of catalyst beneath said catalyst loading apparatus and the alignment apparatus and around said monitoring device, and (v) simultaneously removing the catalyst loading apparatus and the alignment apparatus from the catalyst tube in timed relationship to loading the catalyst particles, wherein the monitoring device alignment apparatus comprises a ring member through which the monitoring device may freely pass and two or more spacing members affixed to said ring member that extend from said ring member towards an inside surface of the tube such that the ring member and the monitoring device are centrally positioned within said tube.
