Gas flaring is a major source of Green House Gas (GHG) emissions and impacts public health due to release of harmful pollutants. Gas flaring from oil and gas industry contributes to 1.5 % of the global GHG emissions.
As part of efforts to improve the environmental performance, ADCO commissioned spiking gas compressors to recover the flared gas and avoid emissions to atmosphere. The associated gas from one of the mid-eastern field is spiked into main oil line until such time as the new Gas plant is fully stabilised. The compressor train consists of reciprocating three-stage compressor, knock-out drum, air-cooler to cool down the compressed gas, metering skid, and glycol Dehydration Package.
Adopting spiking compressor in middle-eastern field provided substantial economic and environmental benefits to the UAE in general and ADNOC / ADCO in particular. In addition to recovery of 98% flared gas, the project resulted in reduction of CO2 and improved the local air quality in the area. The project was registered under the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change (UNFCCC) in 2013 to claim carbon credits. Implementation of this project demonstrates the commitment of ADNOC Group towards climate change mitigation and sustainability.
The paper details the technical features of the project, the environmental, economic, and social benefits associated with recovery of associated flared gas, and the CDM registration process adopted to claim actual carbon credits.
