Catalyst Extraction and Handling

Catalyst handling services for all types of industries

Catalyst Extraction and Handling
Dominion Global

We offer services to industries that use catalysts in their plants' operation and take charge of their management to maximize our customers' efficiency, safety, and environmental sustainability, both in inert and breathable atmospheres.


Our aim is to provide the best possible service through constant innovation and our work teams' continuous learning.


Aside from unloading, cleaning, and loading different kinds of equipment in which catalysts can be found, including the dismantling and assembly of internal parts, we also separate different kinds of unloaded materials, fines, catalysts, and ceramic balls by screening the material. This also allows us to offer our customers a catalyst regeneration or final management service.


Unloading can be done in several ways:

  • Gravity unloading

    Placement of a cutter system at the unloading nozzles through which the product is extracted and stored in different containers (drums, big bags, bins, or others).

  • Vacuum unloading with or without nitrogen recirculation.

    We have an extensive range of closed and nitrogen recirculating vacuum machines.





  • Cardox systems

    A material accumulation removal system, allows for the decomposition of the agglomerated material through the rapid release of carbon dioxide.

  • Catalyst screening

    We have screening equipment with different-sized sieves that allow us to exhaustively separate several kinds of catalysts, dust, and ceramic balls of different sizes.

Mechanical work

Different kinds of work must be performed during the unloading process in order to gain access to the areas where the material to be unloaded is found. This involves:

  • Internal part dismantling and assembly

  • Basket dismantling and assembly






  • Scallop dismantling and assembly

  • Mesh repairs


Once the unloading has been completed, we do cleaning work on the unloaded machine, which may consist of different types of cleaning depending on the customer's requirements and the type of unit, including:

  • Internal dry cleaning

  • Internal cleaning using a high-pressure lorry

  • Cleaning with water from a high-energy lorry







  • Dry ice blasting

  • Drying of internal parts

  • Passivation/Neutralisation.


We use several loading methods depending on the equipment's characteristics, which may include:

  • Sock loading

  • Dense loading

  • Unidense® loading for primary reformer tubes







  • Dry ice blasting

  • Drying of internal parts

  • Passivation/Neutralisation.

Life support system


In order to ensure the work's safety, we are equipped with Life Support System (LSS) control cabins, which are equipped with all the necessary resources to control and perform work within confined spaces, regardless of whether it is done in breathable or inert atmospheres.


We have semi-autonomous breathing equipment and integral breathing helmets (anti-panic) equipped with primary and secondary air supplies through cylinder blocks, a third independent line, and finally an exhaust cylinder.  The audio-visual communication system allows us to keep in constant touch with the operator, in addition to recording the reactor's internal environmental conditions (O2, LEL, H2S, and temperature).


Our specialists are highly trained to monitor these readings on the life support system's (LSS) control panel while the work is being carried out.

Environment, health & safety and quality


The protection of the health, safety, and quality of the work we perform, and care for the environment are the essential bases of the service we offer our customers.


All our specialists periodically undergo medical check-ups. We can count on a Prevention Department which is constantly learning and conducts ongoing hazard analyses to ensure occupational safety at all times. Special attention is given to work that is done in inert atmospheres through continuous O2, LEL, H2S, and temperature readings.
