Oil in water detection at Revap

Per Julio Fritis

In August 2001, Fluxo, through its represented Ionics Agar Environ-mental, developed, together with Cesbe Engenharia from Curitiba, a project for the segregation of effluents from the Henrique Lage Refinery – REVAP in São Jose dos Campos.

It was the first project developed at a Petrobras refinery for the segregation of effluents. Due to the importance of the event, its start-up was attended by the president of Petrobras at the time.
The project consists of activating automatic gates through Ionics sensors to detect hydrocarbons, thus ensuring the quality of the effluent that is released daily by the Refinery in the Paraíba do Sul River in São Jose dos Campos.

The Ionics sensor is the heart of the Refinery's effluent control system, as it is responsible for detecting the presence of hydrocarbons in the water prior to discharge into the Paraíba River.

For this project, two ID 223/500 sensors with PS220 processor mounted on a calming raft were acquired, and two more ID 223/2500 sensors with PS220 processor that were installed in 2 different detection boxes, where all rain gutters are obligatorily directed to the installed sensors.
In conclusion, the sensors at its start-up showed a high accuracy in detecting the presence of hydrocarbons, surpassing the expectations of equipment operation by the refinery.

Currently, this project is a reference for other Petrobras projects in other units such as Transpetro, DTCS and DTSUL.
