Ultrasound Enhanced Desulfurization and Particulate Removal Technology (USPAC)

Process Description

In order to further improve air quality, according to China’s Action Plan of Energy saving, Emission Reduction, Upgrading and Retrofitting of Coal-Fired Power Plant (2014-2020), air pollutant emissions concentrations of newly-built coal-fired power generating units shall generally meet the emission standards for gas-fired boiler/power generators. This is known as the Ultra-low Emissions Standard, which requires dust, SO2 and nitrogen oxide concentrations in the flue gas to be lower than 10, 35 and 50 mg/Nm3, respectively. JNEP’s ultrasound-enhanced desulfurization and particulate removal technology is capable of controlling SO2 concentration in the treated gas to lower than 35 mg/Nm3 and PM lower than 5mg/Nm3. It has been proven to be an effective approach to achieve ultra-low emissions.

Process Mechanism

This enhanced technology improves the performance of the original ammonia absorption system by optimizing spray density, liquid–gas distribution and the oxidation process. In addition, fine particulates in the flue gas are agglomerated with scrubbing and ultrasound mechanisms, and are removed by our patented demister (Patent No. 2014201864177), which significantly improves the overall SO2 and PM removal efficiency.

USPAC

Technical Advantages

The USPAC technology offers the following advantages compared with a Wet Electro-Static Precipitator (WESP):

  • A small footprint, integrated with the absorption system
  • A simple process flow, installed within the FGD absorber
  • High reliability, less maintenance
  • 30%-40% less capital cost
  • 20%-40% less operating cost, approximately 50% less power consumption
  • No extra process waster cost, no waste water disposal
