Desulfurization+Denitrification+Dust Removal Project

Product Introduction

Xinji Aosen Iron and Steel Group Co., LTD

265 Gas Power Generation Flue Gas

Desulfurization and

Denitrification Project

In order to better meet environmental requirements and respond to the national ultra-low emission policy guidelines, adhering to the concept of "Lucid waters and lush mountains are invaluable assets," and in accordance with the requirements of Document No. 128 issued by the Hebei Provincial Department of Ecology and Environment on environmental emergency response in Hebei Province in 2022, Xinji Aosen Iron and Steel Group Co., Ltd. plans to implement desulfurization and denitrification measures for the flue gas of its 265 gas power generation, in accordance with the requirements stated in the notification for issuing the "Best technical guide of Hebei iron and steel industry environmental performance to Create Environmental Performance A-class ".

To address the environmental pollution caused by the by-products of sodium salts in the conventional soda-based desulfurization method, the project will adopt a calcium-based ultra-fine powder direct injection process as an alternative to the previous soda-based desulfurization method. This approach aims to completely solve the issue of sodium salt by-products and meet the process requirements for achieving environmental performance excellence (Grade A) in accordance with the environmental guidelines.

Furthermore, in the denitrification aspect, the project will make full use of the existing space in the boiler to minimize one-time investments. It will also utilize the temperature range of the flue gas to achieve optimal denitrification efficiency.

Company Profile

Since the beginning of its establishment, Shanghai Xuan Ding( is a subsidiary of Shanghai Prime Metallurgy Technology Co., Ltd. ) has been based on its traditional business (general contracting of furnace engineering), and at the same time has been fully engaged in the development and practice of environmental protection business. Its Furnace Division, Environmental Protection Division and Smelting Division have worked together closely to achieve the beneficial combination of process + environmental protection.

As a high-tech enterprise in Shanghai, Our company has the qualification of environmental protection special design class B and environmental protection engineering general contract.It also has by-product treatment qualification and its own environmental protection material production and processing base based on engineering technology company. Our company is an integrated solution provider, which can realize engineering projects + core environmental protection materials (calcium-based ultrafine powder) supply + by-product recovery (or closed-loop circulation) + operation and maintenance etc.
