Vo haro taken this aotlon booauso tho polychlorinated blphonyl (PCS) content of tho PR fluid has come undor increasing sorutlny of various governmental agendas as an undoslrablo environmental contami nant. In some studios oortaln PCBs havo boon found to bo porslstont as an environmental contaminant and* possibly* injurious to oertaln birds* aquatic and animal lifo. A satisfactory altomato for tho oonont plant fuol oil hosting application would bo olthor Thonainol 55 or Thorainol 66. I havo included six copies each of tho data on thoso two fluids. Thorainol 55 has a pour point of ~40*P which would sake it par ticularly applicable for tho pipeline traoing systems presently using Thorainol PR-0 or PR Lo-Teap. Tho oost of Thorainol 55 is nominally $1.55 per gallon P.O.B. Alvin* Texas. Thorainol 66 is roso--ended as a replacement for Thorainol PR-1 in the primary heating loop on thoso heavy oil burner systems. Thorainol 66 has a pour point of -15*P to -l8*P and will give ooaparablo heat transfer characteristics to Thorainol PR-1 at a lower pumping cost. Tho oost of Thorainol 66 is nominally $3.36 per gallon P.O.B. Anniston* Alabaaa.
