MistFix Insertion Mist Eliminator (US Patent #5985004)
Our patented MistFix® Insertion Mist Eliminator was developed specifically for retrofit applications where the existing vessel had no mist eliminator support or no internal access. We found that the oil and gas industry had a large number of vertical gas Knock Out Drums that were designed to run at relatively low gas rates, and had no internals to promote mist elimination. Over time, plant capacities were increased feeding more gas into the drum than was originally considered. This resulted in increased liquid carryover and these empty KO Drums became a bottleneck. The drums required an effective mist eliminator to increase the capacity. Without the MistFix®, the only solution is to cut apart and re-weld the vessel shell, which will often require extended down time for field work, post weld heat treatment, re-certification and a re-paint. The MistFix® installs without modification to the existing vessel. It drops into the top gas outlet nozzle and hangs from the flange. We recommend a minimum of 8” nozzle diameter. We have used MistFix on both vertical and horizontal drums but note that the gas outlet nozzle must be vertical./td>
The MistFix® is installed without confined space entry.It has proven to be so maintenance friendly, that many refiners have specified its use on new operating units.
To install simply:
1. Unbolt the pipe flange connection from the gas outlet nozzle.
2. Place a new gasket on the flange face.
3. Lower the MistFix® through the nozzle into place
4. Place a second new gasket on the MistFix flange face.
5. Reposition and securely fasten the pipe flange connection to the gas outlet.
