Since 1990, PETROVAL provides dense loading services with the DENSICAT®, the first dense loading machine developped.
Dense loading of fixed bed catalytic reactors is a technique which has been used for a few decades, and has proven to be very useful for reactors debottlenecking and for other vessels filled with particulate materials.
The Catapac® technology is a dense loading process developed by IFP EN to load Axens catalyst. Petroval possesses the exclusive licensee from IFP for all Catapac dense loading.
S-LOAD® is a technology developed and patented by Petroval, for the loading of inert support balls into the bottom of a reactor quickly, safely and without breakage.
The OSCILLOCAT™ is a new dense loading technology resulting from an R&D project between Petroval and a client.
The UNIDENSE™ technology is a catalyst loading method for primary reformer tubes which is less complex and faster than the traditional ''sock'' loading method.
The Dust-Free system was developed by Petroval to dense load hazardous catalysts, prevent dust emission into the atmosphere, and prevent the exposure of personnel.
In addition to dense loading activities, CATFLOW™ is a technology developed and patented by Petroval to unload a reactor catalyst bed via a horizontal dump nozzle.
CARBODUMP® technology deagglomerates catalyst particles joined together by coke or other sticky matter through the adapted use of CO2 cartridges. A rapid expansion of CO2 gas in the clumps of agglomerated catalyst cause the particles to separate.
Petroval has a huge experience of catalyst change-out around the world and working with several catalyst handling companies.
PROBACAT® is a sampling technology that enables catalyst in-situ sampling; without reactor unloading requirement.
Strengthened by 25 years of experience in the refining world, PETROVAL proposes his specialised operator's services by acting as an independent third party.
Our troubleshooting service is based on experience and knowledge developed by Petroval. Throughout our 30 years of experience, we have the objective of identifying and understanding the root cause of process and operational issues.
Petroval provides catalyst screening supervision that is usually done by catalyst handling. Petroval controls and recommends optimizations in order to minimize catalyst breakage and maximize catalyst recovery: unloading rate, catalyst handling, fine rate calculation, mesh size
