On December 18, the additional flue gas desulphurization project for Yangzi Petrochemical Thermal Power Plant was officially started. The total investment in the treatment of coal-fired boiler flue gas will reach 97.26 million yuan. The launch of this project will not only greatly improve the sulfur emission status of Yangzi Petrochemical Company, but also remove the hat of the “large-scale industrial sewage company in Nanjingâ€, and at the same time, it is also a repair of Yangzi Petrochemical's social responsibility image.
It is understood that there are 9 coal-fired boilers and 6 generator sets in Yangzi Petrochemical Thermal Power Plant, with a total installed capacity of 360 MW and a rated total steam production capacity of 2170 tons/hour, which is responsible for the power supply and supply of the Yangzi Petrochemical joint venture company and living quarters. Hot and other tasks. The company's thermal power plant emits 17,500 tons of sulfur dioxide annually, which is the “large sewage blower†in Nanjing City and is listed as the “fifteen†flue gas desulfurization deadline treatment project by the Jiangsu Provincial Government. Although Jiangsu Provincial Environmental Protection Agency supervised the operation several times, the company's flue gas desulphurization project had not started construction during the "10th Five-Year Plan" period, which directly affected the completion of the "Tenth Five-Year Plan" for prevention of acid rain and sulfur dioxide pollution in Jiangsu Province. Yangzi Petrochemical Company did not report the FGD feasibility study report to Sinopec headquarters until early 2006. Recently, the media criticized the project's long delay. Under this circumstance, Sinopec Group Asset Management Co., Ltd. accelerated the approval process for the feasibility study report on the flue gas desulphurization project of Yangzi Petrochemical Company's thermal power plant, and officially approved the report on November 28.
The flue gas desulphurization project of Yangzi Petrochemical Thermal Power Plant adopts a relatively mature, advanced and reliable "ammonia-fertilizer desulfurization" technology at home and abroad, and is preparing to use the ammonia material produced by the company's refinery acid water stripping device and the thermal power plant. The sulfur dioxide produced by coal-fired boilers undergoes a neutralization reaction to produce a product with higher added value, ammonium sulfate fertilizer. This can achieve the purpose of "using waste to treat waste" without causing secondary pollution.
The implementation of gas desulphurization projects will be rigorously controlled by five major projects including “Investment, Quality, Progress, Safety, and Contractsâ€. First, we will ensure the completion of the flue gas desulphurization projects for 2 coal-fired boilers in thermal power plants in 2007 and complete the completion of 3 coal-fired boilers by 2008. Gas desulfurization task. In 2009, we will increase investment and complete the desulfurization management tasks for the remaining four coal-fired boilers.
