China Unveils Cutting-Edge Flue Gas Waste Heat Power Generation Unit

China National Offshore Oil Corp (CNOOC) has inaugurated a breakthrough flue gas waste heat power generation plant in Tianjin Municipality. The equipment, the world's first of its sort, will be demonstrated at the Wenchang 9-7 oilfield development project. Using high-temperature flue gas for clean energy represents a significant technological advancement in offshore oil and gas operations.

This is a huge development in the use of gas waste heat to generate clean energy.

The newly developed unit, the world's first 5MW offshore high-temperature flue gas waste heat power production unit, will be shown in the Wenchang 9-7 oilfield development project, CNOOC announced.

Until date, there have been no recognised strategies for using high-temperature waste heat offshore, either globally or domestically. China Media Group (CMG) reports that this revolutionary equipment represents a significant technological breakthrough in offshore oil and gas operations.

Traditionally, the power station serves as the foundation of an offshore platform, generating energy through the combustion of on-site extracted oil and gas. However, this process generates a significant amount of high-temperature flue gas, which has emerged as a major source of carbon emissions in offshore oil and gas development.

The flue gas waste heat power generation unit uses the high-temperature flue gas produced during power plant operations as a heat source. It transforms this waste heat into clean power. Compared to conventional flue gas combustion and emissions, the incorporation of this high-temperature waste heat power generation unit can elevate the waste heat utilisation potential of the power station to 60 to 70 percent, significantly enhancing energy efficiency, according to CNOOC.

Upon deployment, the overall energy efficiency of the primary power stations is anticipated to rise by 7 percent. This enhancement is poised to curtail the consumption of crude oil and natural gas in offshore oil and gas fields, stated An Weizheng, the chief engineer of mechanical and electrical instruments at the Engineering Research and Design Department of CNOOC Research Institute.

Once operational, the unit's annual waste heat power generation capacity might reach 40 million kWh, enough to cover the electricity needs of 30,000 families. It is also expected to save roughly 300 million cubic meters of natural gas use over a 20-year period and offset around 800,000 tonnes of carbon dioxide emissions, which is equivalent to growing 7.5 million trees, according to CNOOC.
