As I have already written in our previous blog, in this occasion we will enumerate processes in those white oils are used, being two the mainly ones: • as heat transfer fluid…
The white oils and their uses in the industry (I)
The white oil is obtained starting from paraffinic fractions of mixed base or naphthenic one, depending on the definitive use. The process is carried out for vacuum-distillation, followed by several refinement processes, included a final purification with catalytic regeneration. Their applications are specially important in products that have direct and forced contact with the human being, for what should be no toxic, not to stain and nor to contaminate.
The thermal fluid transmitters of heat
In reference to the viscosity, it is considered from two points of view: separately and its variation in reference to the temperature.
The oils have advantages in comparison with other fluid, thanks to their better relation viscosity/temperature, that it is expressed in terms of the Index of Viscosity. It is calculated by an empirical formula from viscosities at 40º and at 100º C. A high value means a small change of viscosity in relation to the temperature.
New ATEX heater of Pirobloc
PIROBLOC already has in operation a new thermal fluid heater in which their components fulfill ATEX rules (for facilities in atmospheres with explosion risk). In this occasion, we have supplied again for the petrochemical sector, a…
