DENSICAT®

Loading Technologies
LOGO - DENSICAT

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.

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: 

  • No ballistic separation 
  • No catalyst segregation 
  • Better homogeneity of the catalyst bed 
Loading rate  8 to 14 tons/hour. Fasted rate: 15 to 28 tons/hour. Dense loading time reduced.
