GEA provided four custom-engineered chilling systems to cool process gas streams of upstream field in the Mediterranean Sea.

GEA was selected by KT - Kinetics Technology to provide a process gas chilling solution for use on the Sulphur Recovery Units (SRU) supplied by KT at the Zohr gas field. The Zohr field is the largest offshore natural gas field in the Mediterranean Sea located in the Shorouk Block in the Mediterranean Sea’s Egyptian sector with onshore treatment facilities. In the Shorouk Block, Eni holds a 50% stake, Rosneft 30%, BP 10% and Mubadala Petroleum 10% of the contractor’s share. The project is executed by Petrobel, the operating company jointly held by Eni and the state corporation Egyptian General Petroleum Corporation (EGPC), on behalf of Petroshorouk, jointly held by contractor (Eni and its partners) and the state company Egyptian Natural Gas Holding Company (EGAS).

The Customer Challenge

The requirement demanded chilling of the water circuit that cools down several process streams inside the Tail Gas Treatment (TGT) and Acid Gas Enrichment (AGE) sections of the sulphur recovery units. The SRUs are an important aspect of the overall project operation as they contribute to the recovery of the sulphur contained in the gas extracted from the wells before delivering it to the national grid.

The GEA Solution

To meet the customer requirements and stringent environment conditions, GEA oil & gas experts designed and assembled four chilling systems (one for each SRU on accelerated startup and ramp up to plateau phases of the Zohr Development Project) to most effectively cool the process streams to the desired temperature.

The chillers utilize GEA Grasso LT-V, oil-injected screw compressors with air-cooled condensers. Using R134a as the refrigerant, the systems utilize 350kW motors and provide cooling duty of 1,008 kW.
