ETI Oil Treating Variance Solution (OTVS)

The ETI Oil Treating Variance Solution (OTVS) is a patented process* designed to use indirect heating and multi-stage separation to meet RVP or Vapor Pressure of Crude Oil (VPCRx) specification prior to entering oil storage tanks.  The OTVS system provides the following benefits:

  • Reduced Footprint – The use of the indirect heaters allows it to be placed closer to storage tanks resulting in reduced well pad space and costs.
  • Safety – The use of indirect heat provides increased operational safety.
  • Recovery – The OTVS system provides higher oil yields at the desired vapor specification.
  • Specification (RVP) – The OTVS system produces an on-spec vapor pressure product (oil) by controlling the process to near atmospheric pressure.
  • Environmental Impact – The OTVS process results in less liquid to the gas phase being sent to flare and also provides a reduced plot space.
