Van Phong 1 Thermal Power Plant – FGD Performance Pretest

Flue Gas Desulfurization (FGD) system Performance Test:

  • Receiving the trust of MHI Solution Technologies (MHI Soltec) – Manufacturer of SWFGD system, Chugai Technos performed the performance testing trial of a seawater flue gas desulfurization (SWFGD) system for unit 1 and unit 2  with the following items:
    • Measurement and analysis of exhaust gas at FGD inlet and outlet, bypass, and stack;
  • The monitoring equipment system complies with Japan JIS standards, meeting the characteristics of the sampling location (horizontal duct, depth of 7m at the outlet of the FGD system);
  • Measurement parameters: temperature, pressure, velocity, flow rate, moisture content, gas composition (O2, CO2, and N2), SO2 concentration; dust concentration.
  • Report content:
    • The basic exhaust gas parameters (including: temperature, pressure, velocity, flow rate, moisture content, gas composition);
    • SOconcentration;
    • SO3 concentration;
    • Dust concentration;
    • Desulfurization efficiency;
    • SOconcentration distribution; dust concentration;
  • Chugai Technos team of engineers performed the work in night operating conditions according to the operating schedule of Van Phong 1 Thermal Power Plant with difficult working conditions. Accompanying experienced engineers who are leading Japanese industry experts and Indian engineers, Chugai Technos has made good use of its resource advantages to work with customers to build the most optimal solution, meet the actual situation, support FGD producer to operate the system in the most optimal conditions.
