Shipping container-mountable system for making bio-sourced oil dielectric fluids

A mobile apparatus for processing a bio-sourced oil to provide a bio-sourced oil dielectric fluid comprising:

• a pump and heater array, an adsorbent media array, wherein the adsorbent media array is configured to remove polar impurities from bio-sourced oil;
• one or more filter arrays downstream from the adsorbent media array, wherein the filter arrays in aggregate retain particles of 0.5 micron or larger with a beta rating of at least 200;
• a degasser and vacuum system array;
• an additive metering/mixing valve system;
• and a plumbing system fluidly interconnecting the pump and heater array, the adsorbent media array, the one or more filter arrays, the degasser and vacuum system array, and the additive metering/mixing valve system, wherein:
• i) the mobile apparatus is configured with controls to maintain bio-sourced oil at a temperature of at least 60° C. throughout a method carried out in the apparatus, ii) the mobile apparatus is configured with controls to prevent exposure of bio-sourced oil to a pressure differential greater than 300 kPa throughout a method carried out in the apparatus, iii) the mobile apparatus is configured with controls enabling the mobile apparatus to be operated on an electrical supply of from 100 kW to 2000 kW of power, and iv) the pump and heater array, the adsorbent media array, the one or more filter arrays, the degasser and vacuum system array, the additive metering/mixing valve system, and the plumbing system are mounted on a mobile transport platform system having a total footprint of no more than 30 m2.
