An engineering-environmental-economic-energy assessment for integrated air pollutants reduction, CO capture and utilization exemplified by the high-gravity process.

In this study, a high-gravity (HiGee) process incorporating CO and NO reduction from flue gas in a petrochemical plant coupled with petroleum coke fly ash (PCFA) treatment was established. The performance of HiGee was systematically evaluated from the engineering, environmental, economic, and energy aspects (a total of 15 key performance indicators) to establish the air pollution, energy efficiency, waste utilization nexus. The engineering performance was evaluated that lower energy consumption of 78 kWh/t-CO can be achieved at a capture capacity of 600 kg CO/t-PCFA.

Development and deployment of integrated air pollution control, CO capture and product utilization via a high-gravity process: comprehensive performance evaluation.

In this study, a proposed integrated high-gravity technology for air pollution control, CO capture, and alkaline waste utilization was comprehensively evaluated from engineering, environmental, and economic perspectives. After high-gravity technology and coal fly ash (CFA) leaching processes were integrated, flue gas air emissions removal (e.g.

Environmental Benefit Assessment for the Carbonation Process of Petroleum Coke Fly Ash in a Rotating Packed Bed.

A high-gravity carbonation process was deployed at a petrochemical plant using petroleum coke fly ash and blowdown wastewater to simultaneously mineralized CO and remove nitrogen oxides and particulate matters from the flue gas. With a high-gravity carbonation process, the CO removal efficiency was found to be 95.6%, corresponding to a capture capacity of 600 kg CO per day, at a gas flow rate of 1.
