Prosernat: Updates from Mexico and Qatar

Published by
Hydrocarbon Engineering,


Prosernat and Arendal have signed a cooperation agreement to mutually strengthen their capacities to offer turnkey advanced technological solutions to the Mexican oil and gas market and beyond.

As part of the agreement, the companies will:

  • Jointly scout the Mexican market and promote Prosernat technologies.
  • Identify and win joint business opportunities in suitable Mexican markets: technology in Prosernat’s portfolio and modularisation of open art process units.
  • Support Arendal in its appraisal of setting up a yard in Mexico to address the American market.


Prosernat has announced the successful testing and operation of a giant multi functional 1.1 billion ft3 acid gas removal unit (AGRU) in Ras Laffan Industrial City for Qatargas.

The new AGRU is part of a major debottlenecking performed for the Qatargas 1 LNG plant in Ras Laffan in order to maintain its 10 million tpy LNG production while coping with increased levels of H2S and CO2 in the feed gas. The project, known as the Plateau Maintenance Project (PMP), involves the construction of an additional AGRU treating (in a single train) 1100 million ft3/d of natural gas, an associated sulfur recovery unit (SRU) and tail gas treatment unit (TGTU) within the minimum plot area allocated to the greenfield section of the project.

The new multi functional AGRU has been designed by Prosernat under the AdvAmine™ MDEAmax technology based on open market MDEA solvent. The design fully integrates the acid gas removal unit, the acid gas enrichment section and the amine section of the TGTU. This has been considered as the most effective solution to install a new compact plant inside the existing facilities, which needs to meet multiple process requirements with high operational flexibility.

The 1.1 billion ft3 AGRU was successfully started up at the end of 2014. Performance tests were completed beginning of 2015 and demonstrated that all the guarantees associated with the AGRU, the enrichment of acid gas section and the TGT amine section at design and turndown capacities meet expectations without any operational issues.
