Since 1990, PETROVAL provides dense loading services with the DENSICAT®, the first dense loading machine developped. It is the most effective dense loading technology widely used in the industry, with more than 40,000 tons of catalyst loaded per year.
DENSICAT® machine loads instantaneously 100% of the reactor surface with a high loading rate (up to 28 t/h). With this technology, the catalyst distribution is not based on centrifugal force, ensuring an optimal and homogeneous distribution of the particules.
COMPARISON BETWEEN DENSICAT® AND OTHER DENSE LOADING METHODS
|30% - 40%||100%|
|Limited loading distribution: Less homogeneous catalyst bed.||More homogeneous loading distribution: Catalyst bed more homogeneous.|
|Catalyst ejected through a distribution tool.||Catalyst loaded through a barrel by gravity and spread by whips.|
Centrifugal force and catalyst
|Catalyst ejected from a distribution tool: Ballistic separation by virtue of centrifugal force: catalyst segregation (smaller particles loaded in the middle and bigger particles at the walls).||
Catalyst not ejected from a distribution tool:
|Loading rate||8 to 14 tons/hour.||Fasted rate: 15 to 28 tons/hour. Dense loading time reduced.|
|Dense loading operation||Companies certified by licensors/Limited number of full time employed operators.||Specialised team of 30 trained and certified specialised operators (engineer level) directly employed by PETROVAL. The catalyst loading is their full time job on a world wide basis.|
