Gas cylinder recycling unit CRU-48

The units of the CRU Series have been developed for easy and cost-efficient inhouse recycling of gas cylinders.

MANY CHALLENGES

Particularly challenging is the disposal of acetylene cylinders. Acetylene gas cylinders with a damaged porous mass contain a significant amount of solvents. This leads to the following issues: 

  • A separation of the bottle body with a mass containing solvents hold explosion risks 
  • The disposal of the porous mass in which solvent is still present to a disposal site is unlawful without proper pretreatment and endangers the environment.
  • The disposal of such gas cylinders is very expensive

We offer you the solution: INHOUSE recycling with your own gas cylinder recycling unit

 

The vacuum pump evacuates the separating vessel as well as the attached gas cylinders. After reaching the preset vacum limit the induction heating is activated and the distillation process begins.

The gas cylinders are heated slowly until the acetone changes from liquid to gaeous state. The resulting gas is exhausted by the vacuum pump through a pleate heat exchanger. The is condensed in the heat exchanger and collected in the separating vessel in liquefied state.
