  • Study on Treating Sintering Flue Gas with Coking Wastewater
    Advanced Materials Research, 2013
    Co-Authors: Jian Jun Dong, Wu Feng Jiang, Yu Zhu Zhang
    Abstract:

    There are large amount of ammonia in coking wastewater. It is a good recycling desulfurizer. Sintering Flue Gas has the characteristics, such as large amount of, low SO2 concentration, great changes of operation load. Treating sintering Flue Gas with coking wastewater can attain the destination of treating waste with waste. This paper adopts a spray tower countercurrent device, and SO2 concentration in the entrance and exit Flue Gas is on line detected by an automatic Flue Gas detection instrument. The paper studies on the change rule of SO2 concentration in the process of treating sintering Flue Gas using coking wastewater, and the inFluence of SO2 initial concentration in sintering Flue Gas to the desulfurization rate. The results show that after being treated the sintering Flue Gas can reach the emission standard for air pollutants of iron and steel industry.

  • Study of Dual-Alkali on Sintering Flue Gas Desulfurization
    Advanced Materials Research, 2011
    Co-Authors: Yu Zhu Zhang, Ying Xu
    Abstract:

    Combining with the characteristics and control methods of sintering Flue Gas, several common methods for Flue Gas desulfurization(FGD) and development trend of desulfurization technology were described in this paper. According to characteristics of sintering Flue Gas and selection principles, dual-alkali method was used in the FGD. Desulfurization process, basic principle and characteristics of the process were studied in detail. By contrast test, the effect of concentration of the desulfurization, Flue Gas flow and surface active agent on the desulfurization efficiency was investigated in detail through calculating the pH value of the solution before and after desulfurization reaction.

  • Removal of Sulfur Dioxide from Sintering Flue Gas with Coking Wastewater
    Advanced Materials Research, 2011
    Co-Authors: Wu Feng Jiang, Yu Zhu Zhang
    Abstract:

    Coking wastewater comprising a lot of ammonia is a good desulfurizer for recycling. Sintering Flue Gas is characterized by large volume, low sulfur dioxide (SO2) concentration and large variation amplitude and etc. The purpose for treating waste with waste can be carried out by treating sintering Flue Gas with coking wastewater. This paper uses a spray tower countercurrent device, ensures the contact between coking wastewater and sintering Flue Gas, and detects SO2 concentration of inlet Flue Gas and outlet Flue Gas on line by using an automatic Flue Gas detection instrument. This paper studies on the change regularity for the SO2 concentration at outlet Flue Gas during the process of treating sintering Flue Gas with coking wastewater, the inFluence of SO2 initial concentration in sintering Flue Gas to the removal efficiency of SO2, the inFluence of Gas-liquid ratio between the sintering Flue Gas and the coking wastewater to the removal efficiency of SO2, and the change regularity for the pH value of coking wastewater after desulfurizing. The results show that the sintering Flue Gas which is treated can live up to the atmospheric pollutant efFluent standard of iron and steel industry; the pH value of coking wastewater is reduced after treating, and the conditions for the implementation of subsequent coking wastewater treatment process are provided.

  • Carbon dioxide capture strategies from Flue Gas using microalgae: a review
    Environmental Science and Pollution Research, 2016
    Co-Authors: Daniya M. Thomas, Jerry Mechery, Sylas V. Paulose
    Abstract:

    Global warming and pollution are the twin crises experienced globally. Biological offset of these crises are gaining importance because of its zero waste production and the ability of the organisms to thrive under extreme or polluted condition. In this context, this review highlights the recent developments in carbon dioxide (CO2) capture from Flue Gas using microalgae and finding the best microalgal remediation strategy through contrast and comparison of different strategies. Different Flue Gas microalgal remediation strategies discussed are as follows: (i) Flue Gas to CO2 Gas segregation using adsorbents for microalgal mitigation, (ii) CO2 separation from Flue Gas using absorbents and later regeneration for microalgal mitigation, (iii) Flue Gas to liquid conversion for direct microalgal mitigation, and (iv) direct Flue Gas mitigation using microalgae. This work also studies the economic feasibility of microalgal production. The study discloses that the direct convening of Flue Gas with high carbon dioxide content, into microalgal system is cost-effective.

  • Flue Gas cleaning for co2 capture from coal fired oxyfuel combustion power generation
    Energy Procedia, 2011
    Co-Authors: Marie Anheden, Richard Faber, Robert Preusche, Holger Ecke, Daniel Kosel, Norbert Jentsch, Fredrik Starfelt, Nader Padban, Goran Lindgren
    Abstract:

    Abstract Current progress in Flue Gas cleaning for CO 2 capture from oxyfuel combustion has been described based on conceptual development, fundamental understanding and practical tests at the Schwarze Pumpe Oxyfuel Pilot Plant (OxPP). Significant improvement in understanding the characteristics of SO x , NO x , particulate matters (PMs) and non-condensable Gas components in Flue Gas cleaning processes provide a scientific basis for further developments of Flue Gas cleaning technologies. Testing results from pilot studies have proved that Flue Gas cleaning systems have reached the achievable performance and have also shown that there is generally no fundamental technical bottleneck for most of the Flue Gas cleaning technologies. Further developments should focus on comprehensive optimisation of the Flue Gas cleaning processes combined with boiler and downstream CO 2 compression processes. Changes in Flue Gas cleaning technologies may be excepted if more attractive Gas cleaning processes could be successfully developed in the near future; for example, NO x removal and control technologies. The development of a monitoring approach for the mitigation of non-condensable Gases is an important operational issue for largescale oxyfuel combustion plant.
