The early summer season with lush green trees and full of vitality,Sunjiacha Longhua Mining CompanyCoal classification and quality clean, efficient and comprehensive utilization project，Resumption of work after approval of energy conservation review。At the construction site，Boiler Basics、silo pile foundation、Civil construction projects such as office building m88 casino reviewfoundations are at full capacity，A busy scene。
The implementation of this project is for Sunjiacha Longhua Mining Company, a mixed ownership enterprise，It is to achieve low-carbon development of high-carbon resources through high-quality projects、The best comment on the green development of black coal。The black coal will pass through the densely curved pipes，Enter production device，Converted、Upgrade、Step utilization，Generating high value-added synthetic ammonia、Urea and other colorless liquids or white crystals，Introduced into the market to serve industrial and agricultural production。

In recent years，The company seizes the last window period，Focus on "Carbon Peak"、Carbon Neutrality” goal，The original coal classification, quality, clean, efficient and comprehensive utilization project，Optimize and upgrade technical routes and product solutions，After the energy conservation review of the project was approved by the Shaanxi Provincial Development and Reform Commission at the end of April，Project construction resumes in full。
This project is the company’s resolute implementation of Shaanxi Coal Group’s “carbon preservation、Decarbonization、Carbon reduction、Carbon sequestration、Yi Carbon” five-carbon development path，Relying on its own coal resource endowment，Laying out the high-end fine chemical industry chain，Developing “coal head to tail”，Planning、Reserve，Comprehensive utilization project under construction。Total project investment 70.700 million yuan，The main construction content is to produce 500,000 tons of synthetic ammonia per year、800,000 tons of urea、60,000 tons of melamine and new material production equipment and supporting related public projects，To date, a total of 12 investments have been completed.0.6 billion yuan。As understood，The project is only 700 meters away from the company’s coal storage shed，Be able to make full use of the advantages of the pit mouth，Reduce transportation costs，Achieve on-site clean and efficient conversion of coal。
The project adopts m88 casino reviewclean coal gasification、Ammonia synthesis、Low temperature methanol washing、Sulfur recovery、Isothermal transformation、Advanced, mature and reliable technologies such as liquid nitrogen washing，Production of synthetic ammonia，Use synthetic ammonia as raw material to produce urea、Melamine and other products。Urea, the main product of the project, is used in agriculture，Conducive to the increase of my country’s grain production。
Key chess for comprehensive utilization of resources
Riding on the momentum，Relying on projects，Take a solid step towards comprehensive utilization of resources。The company not only proposed ambitious goals，It has actually improved the industrial chain。
After the completion of the clean and efficient comprehensive utilization project of coal classification and quality: the coal washed from the company's coal washing plant will be sent to the gasifier for synthetic ammonia production，Methane and other combustible gases remaining after processing synthetic ammonia、Send coal slime and coal gangue to the power plant to be used as fuel for power generation，Electricity produced by power plants、hot、Vehicle delivered to coal mines and chemical plants for use；Synthetic ammonia finally produces urea。The formation of a complete "from black to white" industrial chain from coal to synthetic ammonia to urea products。A piece of coal is transported、Processing、Convert until urea product is produced，Contaminants in the entire process are efficiently purified and controlled，Coal gangue associated with the coal mining process、Drainage water can be managed through technological innovation and comprehensive management，Achieve “Eat dry and squeeze clean”、Turn waste into treasure。
“The biggest feature of the project is the comprehensive utilization of coal by grade and quality，The value of coal resources is sublimated here。”Executive Director of Longhua Coal Technology Company、Introduction by General Manager Liu Xiaoyi。“The epidemic has affected the project progress，brings challenges to various tasks，We take epidemic m88 casino reviewprevention with one hand，Construction with one hand，We are accelerating the preparation and implementation of rush measures，At full capacity from May，Seize the golden construction season，Make every effort to ensure the realization of annual construction goals。”
This project is an important link in the company’s “56311” high-quality development goal，It is also the main strategic plan for the company’s transformation and upgrading。Behind the gorgeous turn of a piece of coal，It is a crossover from coal mining and selling to coal chemical industry，Represents a dynamic change in enterprise development。
A new path for energy conservation, consumption reduction and emission reduction
The company follows the concept of energy conservation and consumption reduction，Think ahead in design and craftsmanship，Strive to reduce the energy intensity of projects，Introducing advanced energy-saving technology and new processes。After energy saving optimization，The overall project can save approximately 250,000 tons of standard coal per year。
This project adopts extensive measures to save water and electricity，Can save about 3 million tons of water every year，Saved approximately 48 million kilowatt hours；Make full use of the large amount of high-temperature process waste heat generated by the coal gasification unit，The converted driving power is about 50,000 kilowatts，Waste heat by-product 11MPa high pressure steam 170 tons/h；Efficiently utilize the large amount of reaction heat generated by ammonia synthesis，Waste heat to generate electricity，Can generate about 2 electricity per hour.50,000 kilowatts；Coal gasification furnace and CO conversion are integrated with centralized layout and low resistance design，The total hourly reduction of the drive shaft power of the transmission equipment is about 1.10,000 kilowatts。At the same time, some of the production water taken from the project will be treated by mine drainage water and reused，Remarkable results in water saving，The project’s water consumption index is in the leading position in the country。
“Longhua M88 logincoal is high-quality gasification coal，New project uses coal to make synthetic ammonia to produce urea，Its high added value，At the same time, it is conducive to energy conservation and emission reduction。Urea production from coal is an agricultural industry，The market is relatively stable，Current national industrial policy support，Also in line with Yulin City’s coal chemical industry high-end transformation strategy，We want to be high-end、Intelligent、High-quality visualization project turns coal resources from black to white，Strive to become the country’s leading energy and chemical enterprise”，Company Party Committee Secretary、Chairman Gao Jie said。
Keep doing it，The future is promising。Taking green circular development as the keynote，Using high-quality projects as the engine，The company will embark on a clean and efficient transformation of coal resources from "black" to "white"，Differentiation、New path of high-end circular development。(Xue Zhuang)
