1. A method of lubricating and cooling mechanical seals at high pressure comprising the steps of:

  • (a) confining a lubricant/coolant liquid to a high pressure vessel;

    (b) maintaining a high pressure gas phase over the top of said confined lubricant/coolant liquid within said high pressure vessel;

    (c) providing a motor driven pump and closed fluid recirculation loop in fluid communication from said lubricant/coolant liquid maintained at high pressure within said high pressure vessel to the mechanical seals to be lubricated and cooled and then back to said high pressure vessel; and

    (d) pumping said lubricant/coolant liquid through said closed fluid circulation loop, thus cooling and lubricating the mechanical seals at high pressure with minimum energy input to said pump.
