What is The Possibility of Using the Existing Large-Sized Equipment of the Units when Switching to New Oil Treatment Technologies about?

## Abstract Oil treatment at field stabilization units allows preparing oil for storage and transportation, including by reducing the RVP and hydrogen sulfide content in oil. However, the use of direct fire heating of oil in pipe stills to maintain the thermal regime in the stabilization column may cause the formation of secondary hydrogen sulfide as a result of the thermal decomposition of heavy sulfur-containing hydrocarbons, which leads to additional financial losses for bringing the stabilized oil to the requirements of the current regulatory documents. A way to reduce the amount of secondary hydrogen sulfide is the transition from direct fire heating of oil to heating through an intermediate high-temperature coolant. In this case, the thermal regime of the stabilization column operation is maintained by heating in the reboiler, while it remains possible to use the existing unit columns and stills without their significant retrofitting.
