Transformer oil regeneration unit UVR-L (laboratory)

The UVR-L laboratory regeneration unit is designed to purify fuels and regenerate oils with viscosity below 70 cSt at 20ºС.

This equipment is very versatile, capable to treat practically any type of oil products including transformer, industrial and turbine oils, as well as fuel oils, gas condensate and diesel fuels.

The laboratory version of this product can be used by either research facilities or companies which already own larger UVR units.

The potential scope of UVR-L functions is:

  • to study efficiency of various adsorbents for purification of oil products;
  • to optimize purification of waste oil by larger UVR plants;
  • to evaluate the efficiency and the rate of regeneration when shanging initial conditions, to access sorbent consumption depending on the type of oil product.

UVR-L design

The laboratory unit for purification of fuels and regeneration of oil consists of a regeneration pod, a frame, a vacuum chamber, a vacuum pump, a control cabinet, a coalescer dryer and piping.

Operation Principle

Operation principle of the UVR-L unit is based on heating, vacuum treatment and regenerating properties of the adsorbent.

The required amount of adsorbent is filled into regeneration pod. Oil flows through the adsorbent and then fills the vacuum chamber. The vacuum pump creates the required negative pressure. When the regeneration process is completed, a special valve opens and recovered oil is drained from the vacuum chamber.

Structurally, the regeneration pod is a tank, half filled with the adsorbent. There is a lid in the upper part. It is used for oil or adsorbent input.

The lower part of the regeneration pod contains a rubber hose filled with adsorbent and the lower lid, through which vacuum is applied, saturated sorbent is removed and oil is sampled.

The upper surface of the module is equipped with a heater strip and is insulated.
