CHECKING

Mourik Industry uses various methods and technologies to inspect whether the work is done correctly. One of our most recently developed technologies is the M-Ty, a tool attached to the M-lance that checks whether the tubes are completely emptied after unloading the catalyst. After loading, catalyst tubes are checked for density and pressure drop and corrected where necessary. Developed in-house, our patented pressure drop measurement equipment M-Dp measures the differential pressure and records up to eight readings simultaneously. Digital readings ensure accurate measurement and make progress control and qualitative reporting possible.

In order to check the homogeneity of the catalyst, the pressure drop of each tube is measured. To ensure that all tubes are measured in an identical manner, Mourik uses specially designed and patented pressure drop equipment. The technologies use mass flow controllers to keep the flow constant in order to ensure a stable, reliable and repeatable air flow per measurement. This data is transferred to a computer and analyzed.

In the reactor, the final calibration of multiple instruments is done by adding a positive or negative offset in the measured value. The dP measurements shall not exceed +/- 3% of the average differential pressure of all measured tubes. Tubes that do not meet this requirement will be adjusted until they meet this tolerance criteria.

Mourik’s pressure drop system will measure and record up to eight readings simultaneously, which can be extended in the event of very large reactors using multiple systems. This way Mourik can expand the system up to 16 simultaneous measurements.

The pressure drop equipment is also used during the loading of the thermocouple tubes to achieve the calculated value.

Verifying the loading quality of every tube

M-DP

The M-Ty is a handheld device attached to the M-Lance. While the M-Lance is carrying out a run, the operator performs a cross-check of the previous batch of pipes with the M-Ty. This way of working eliminates the tedious and time-consuming manual check that used to be necessary after unloading the reactor, thus saving valuable turnaround time and removing a potential fault point.

The M-Ty measures with a constant airflow whether the tubes are completely emptied. If this is the case, a green marker appears and the operator closes the tube with a green cap. If the tube is not completely emptied, a red marker appears and the operator shields the tube with a red cap. When finishing unloading, the top tube sheet is covered with green and some red caps. The red spots needs to be reworked, until the all of the top sheet is green. This way the M-ty contributes to an efficient and secure unloading process.
