At 8:17 on October 30, in the million people longing, the Pine Island, the leading chemical production base - ammonia plant opened up all the processes, and a smooth output of the first batch of qualified liquid ammonia. At this point, which lasted three years, Dahua Group transformation of ammonia removal "coal for oil" project draw to a successful conclusion.
Dahua Group, Pine Island, base of synthetic ammonia device mainly consists of air separation, coal gasification, transformation, purification, ammonia synthesis process and public works constituted. With the old factory "30 million" compared to tons of synthetic ammonia plant, the project apart from coal and oil into the first head, greatly reduce production costs, the entire unit is also under the full implementation of clean energy strategy group design requirements in terms of technology upgrades, energy-saving environmental protection , value-added products, as well as to create circular economy has improved significantly: Setting up the core of coal gasification process, to adopt the international mainstream GE patented technology, coal-water slurry pressurized gasification, emissions by the four Blackwater flash processing, it can recycling, more stable , energy saving, environmental protection; purification process the additional three desulfurization equipment, not only to ensure compliance exhaust emissions of hydrogen sulfide and sulfur by-product annually 4,000 tons, an increase of the value-added products; a new air separation unit of output argon argon will also bring new benefits of growth.
In order to ensure device safety and environmental protection test as soon as possible get through processes, the past few days, the project department to actively urge the construction units lacking complete elimination, while enhancing training to upgrade staff emergency response capacity, and invited experts to the scene to guide commissioning and production preparation work to ensure foolproof. October 25, process gas smoothly get through the whole process, start to restore the synthesis of catalyst temperature. Period, due to steam pressure and power Kenneth factors such as the impact of ammonia out of the process of twists and turns, but the project team through unremitting efforts, installation finally qualified ammonia output.
Up to now, output of synthetic ammonia device has been more than 800 tons of liquid ammonia, liquid ammonia sent to the United Alkali plant and carbon dioxide. (Where Bai)
