Solvent recovery system VOXAL CRYO [ Return towards Organic Volatile Compounds treatment ]

Safe, effective and flexible solution for treating VOCs

VOXAL CRYO is a range for the treatment of effluent gas with concentrations of VOCs (>5 g/Nm3) for effluent gas flows of under 2,000 Nm3/hr.

Cryocondensation, or cryocristallisation, is one of the techniques for treating VOCs. It allows them to be recovered in liquid or solid form. The technology is reliable, particularly flexible and can be adapted to every problem situation.
When liquid nitrogen is used to cool the condenser, VOC emissions are reduced to very low levels by trapping the VOCs quickly at very low temperature. The refrigerant capacity required for the treatment can be adjusted to suit your needs and objectives.

This straightforward and effective principle is illustrated on the phase diagram (figure below):

Range

Type	Waste gas volume flow(Nm³/h)
Mini VOXAL	< 30
VOXAL I	30
VOXAL II	60
VOXAL III	120
VOXAL IV	250
VOXAL V	500
VOXAL VI	1000

Bénéfices clefs

Flexibility of use: adaptable to any flow rate, to any concentration and to most solvent mixes
Nitrogen recycling: Potential re-use of the nitrogen for other applications at output from the facility
Reliability: the straightforwardness of the equipment and the absence of a rotary machine cut equipment maintenance to a minimum.
Low operating costs: exchanger energy optimisation, maximum cold energy recovery thereby cutting nitrogen consumption to a minimum
Safety: the use of liquid nitrogen is a safe way of meeting the constraints of processes presenting special risks (flammability, explosivity, toxicity)

Principales caractéristiques techniques

Optimisation énergétique grâce à la définiton des échangeurs qui récuperent les frigories des effluents traités et / ou de l’azote.
Echangeur principal de type tube-calandre, avec :
- circulation de l'azote liquide et gazeux coté tubes,
- circulation de gaz process coté calandre, au travers d'un jeu de chicanes.
Les tubes sont équipés d'ailettes externes, afin d'augmenter la surface d'échange et l’autonomie en cas de présence d’eau.
Stockage intégré pour la récupération des solvants
Régénération de l’installation
Contrôle commande de l’installation modulable en fonction de vos besoins.
Association possible avec d’autres technologies (adsorption sur tissus de charbons actifs, froid mécanique, etc.)
