  • MerlinPre-conditioning SystemThe solution to top productivity, cost savings & reliability

  • MerlinPre-conditioning Systemis the ultimate protection for all on-line process gas analyzers and equipment against particulates, liquids and mists found in process gases. It employs a patented and innovative technology to protect on-line gas analyzers over a wide range of operating conditions. It is the solution to top productivity and to ensure signicant cost savings in the plants.

  • The heart of the Merlin Pre-Conditioning System is the Merlin Low Flow Cyclone separator. The cyclone separator is designed to handle high loading of liquids and particulates at a very low gas flow rate.

    Using centrifugal forces, it separates liquids and particulates by directing them axially and downward, collecting in the manual knock-out pot. At the same time, sub-micron particulates and mists impinge and adhere to the liquid layer. Cleaned gases flow upward and exit the separator.

    Five years of intense research and development resulted in a technological breakthrough in the Merlin cyclone that prevents splashing inside the separator. Splashing produces fine mists that can easily entrain back into the exiting gas flow, eventually forming larger water droplets and damaging critical downstream on-line gas analyzers and equipment.

    The innovative cyclone core ensures the Merlin Pre-Conditioning System operates effectively and with the highest reliability.

    Innovative Features & the Magical Dierence

  • Innovative Low Flow Rate DesignSpecially designed to work optimally at low flow rate (60-350 Nl/h) commonly found in the analyzer systems. Tested to 2 Nm3/h with no carry-over.

    Green Technology No filter element, no clogging,replacement cost and down time.

    Energy SavingWhen cooling is required, instrument air or cooling water consumption is reduced by up to 50% through ultra-high efficiency condenser.

    Easy InstallationCompletely mechanical design allows for easy installation in hazardous areas.

    How the Merlin Pre-Conditioning System works

    The wet and oily gases enter the Merlin Pre-Separator from the left. Particulates, liquids and mists are first separated by centrifugal forces without using any filter element.

    The gas, saturated with fine particulates and mists, then go into the Galatica Condenser. Larger liquid droplets with fine particulates are formed through slight cooling using vortex cooled air or cooling water. This can be precisely controlled by an optional temperature control valve.

    COMPARISON AS FAST LOOP FILTRATION:

    TRADITIONAL FAST LOOP FILTER/ MEMBRANE SYSTEM

    Employs cyclonic centrifugal forces

    No moving and consumable parts,Significant savings in maintenance costs

    Removes particulates up to 10 micron or finer

    No filter,No clogging issues

    Innovative break through concept for maintenance-free critical fast loop primary filtration

    Employs fine pore media filter element

    Frequent replacement of clogged filter element, High maintenance costs

    Removes particulates and condensate at up to 0.01 micron if not clogged

    Clogged filter results in no flow to analyzers, carry-over damages analyzers

    Design more suited as final protection filter

    The liquid condensate with particulates are collected in the bottom manual knock-out pots for manual draining. Automatic draining is possible with the optional Optimus Automatic Drainer for large amount of liquid condensate with high particulate loading. The cleaned sample exits the system on the right.

    Damaged Analyzers/Equipment

    Traditional Filter and Knock Out system protect on-line gas analyzers by using fine pore filter media (1-7 micron size) or Teflon membrane (0.1 micron size) to trap particulates, liquids and mists. They are selected based on a perceived handling load.

    However, in reality, this perceived handling load is a dynamic factor in plant processes, especially during plant optimizations, startup and upset. When these fine pores in the filter media is clogged with particulates and liquids, continuous flow across the filter media under pressure will result in break through and carry-over. This damages critical on-line gas analyzers for process control and safety monitoring. Filter failure has been known to cause a series of problems in the plant.

    Each year, thousands of dollars are spent replacing clogged or spent filters and knock out systems for on-line gas analyzers. These are only the tip of the iceberg leading to other hidden issues and costs.

    With the loss of quality control, process down time and replacement of expensive damaged on-line analyzers and equipment, plants often suffer significant losses.

    Last but not least, maintenance staff get exposed to unknown chemical hazards. Environment pollution can also occur due to incineration of spent filter elements.

    The running costs of traditional ltration system are high and its impact runs deep.
