Successful start-up of Prosernat amine unit

LNG Industry,

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 Operating Company Limited (Qatargas).

This new AGRU is part of the major debottlenecking performed for Qatargas 1 LNG plant in Ras Laffan, Qatar, in order to maintain the 10 million tpy LNG production from Qatargas 1 Facility whilst also coping with increased levels of H2S and CO2 in the feed gas.

This Project is known as Plateau Maintenance Project and involves the construction of an additional AGRU treating in a single train 1100 million ft3/d of natural gas, an associated sulphur recovery unit and tail gas treatment unit (TGTU) within the minimum plot area allocated to the green field part of the Project.

Multi-functional AGRU

The new multi-functional AGRU has been designed by Prosernat under the AdvAmine™ MDEAmax technology, based upon open market MDEA solvent. This reliable and original design integrates the acid gas removal unit, the acid gas enrichment section and the amine section of TGTU fully. Such innovative and optimised solution could be considered one of the most effective solutions to install a new compact plant inside of the existing facilities that needs to meet multiple process requirements with high operational flexibility.

The 1.1 billion ft3 multi-functional AGRU successfully started-up at the end of 2014 and performance tests were completed beginning of 2015. These demonstrated that all of 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 issue.
