Measuring level in continuous catalytic reforming processes (CCR)

Continuous Catalytic Reforming Processes (CCR)


As a result of a chemical reaction initiated by a catalyst, the hydrocarbon molecules are rearranged in the reformer unit. The catalyst looses its properties over time and thus reactivatiion of the catalyst is necessary in a catalyst regenerator. Radiometric level systems from Berthold are used on the regenerator system to ensure a smooth and continuous reactivation process. Due to high process temperatures and the necessity to measure catalyst levels, the non-contacting technology is the only one which provides reliable level control – the basis for an efficient catalyst regeneration.

Measuring the level and high/low level alarm in catalyst regenerators

By means of a chemical reaction initiated by a catalyst, the hydrocarbon molecules are re-arranged in the reformer unit. The catalyst looses its properties over time and thus reactivating of the catalyst is necessary in a catalyst regenerator.  Radiometric level systems from Berthold are used on the regenerator system to ensure a smooth and continuous re-activation process. Due to high process temperatures and the necessity to measure catalyst levels, the non-contacting technology is the only one which provides reliable level control – the basis for an efficient catalyst regeneration.

Characteristics of continuous level and level switch measurement in catalytic reforming processes (catalyst regenerator)

Measuring the level and and high/low level alarm on hoppers (lock hopper, upper hopper, disengaging hopper)

Reliable and fast responding control of the catalyst level inside the hopper is very important to ensure a high quality process. Each hopper is equipped with continuous level gauges using rod source technology. Rod sources offer highest precision and reliability because the radiation is ideally distributed over the measurement range. Therefore the system will also detect the formation of cones, which means that the true amount of catalyst inside the hopper is determined and filling can be optimized. In addition radiometric level switches are installed to provide high level or low level alarms for safety reasons.

Measuring level and and low level alarm on different hoppers - Customer benefit

 
  • Reliable information on catalyst level
  • Optimal filling and discharging process
  • Improved control of catalyst supply for reforming process
     

Characteristics of Berthold continuous level and level switch measurement in catalytic reforming processes - hoppers

  • Non-contacting, non-intrusive level gaugeContinuous level in combination with level switch measurement on the catalyst regeneratorLevel measurement on the catalyst regenerator
  • The SpeedStar feature ensures extremely fast response times and measuring cycles
  • Best results achieved with Co-60 rod source arrangement
  • Sensitive to cone formation (pile-up cones and downward-pointing cones)
  • Very easy to calibrate (also during on-going process)
  • Immune against interfering radiation, XIP or RID facilitate operation during weld inspections
  • SIL2 / SIL3 certified option

    Radiation Interference Protection (XIP)
    in Level and Level Switch Measurements

    With this feature, radiometric welding checks do no longer interfere the measured value. The measured value is frozen until the radiation interference detection is over.
    A digital output signalizes the detection of radiation interference. All Berthold level measurements are equipped with XIP.
