Abstract: Result of recovery of vapor condensate water from boiler at oil transport tank farm has been unsatisfied due to many technical reasons.Oil content in condensate water exceeds specified standard (5 mg/L) greatly.It can not be utilized consequently and have to be drained locally, which brings about energy waste.Along with a completion of tank repairing engineering project, reforming is taken to oil tank's heater and exporting heat exchanger and several technical measures are taken at the same time, which makes the recovery of condensate water successful.The vapor condensate water recovered at tank farm every year amounts to 4×10⁴ t, water saving volume per year is 5.6 × 10⁴ t, power saving 2.8×10⁴ kW·h per year and oil saving 377.34 t/a.It creates significant economic benefit.
