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
| OTHER LOADERS USING THE CENTRIFUGAL FORCE | DENSICAT® | |
|---|---|---|
| Loading distribution |   |
 |
| Instantaneous loading surface |
30% – 40% | 100% |
|
Homogeneity |
Limited loading distribution: Less homogeneous catalyst bed. | More homogeneous loading distribution: Catalyst bed more homogeneous. |
|
Loading system |
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. |
