Petrobras starts operating the second UPGU module in Rio de Janeiro

BELIZE CITY, BELIZE (Aaron Simonsky, Energy Analytics Institute, 5.May.2025) — Petrobras said the second module of the natural gas processing unit (UPGN) of the Boaventura energy complex, located in Itaboraí (RJ), went into commercial operation. 

This adds to the first module, inaugurated in 2024. Now, the unit’s total processing capacity reaches 21 million m³/day (MMm3/d).

The UPGN is part of Petrobras’ route 3 integrated project, through which gas from pre-salt fields in the Santos Basin is transported, Petrobras announced on 5 May 2025 in an official statement.

This is a rich gas which, after processing, generates 3 products for the market: natural gas (NG); liquefied petroleum gas (LPG or cooking gas); and C5+ (a raw material in the petrochemical industry and fuel production).

Since Nov. 2024, Petrobras has been commercially operating the UPGN of the Boaventura energy complex, contributing to increasing gas supply to the domestic market and reducing dependence on imports.

In addition to the gas pipeline and the UPGN, Petrobras is working on projects in the complex, such as 2 gas-fired thermoelectric plants to take part in the auctions planned by the electricity sector and plans to build other refining units to produce fuels and lubricants, the company said.
