Hubei Sanning’s ammonia synthesis raw material structure adjustment and co-production of 600,000 tons/year ethylene glycol project (Phase I) multi-nozzle opposed coal-water slurry gasifier was successfully commissioned on February 19, 2021.
Hubei Sanning ammonia synthesis raw material structure adjustment and co-production of 600,000 tons/year ethylene glycol project construction have entered the final stage. In order to ensure that the test runs as scheduled, all personnel of the project are not afraid of wind and rain , Get up early and stay in the dark to seize the time to ensure the smooth progress of the node work. Each unit is now starting to turn over the tiles.
At 17:00 on February 15, the No. 1 air separation unit in the air separation workshop of Shibaoshan New Materials Branch produced outbound oxygen products with a purity of 99.96%.
The device has been blasting and purging since May 18 last year, and has completed a series of preparatory work such as turbine rush rotation, three-machine coupling test run, and device major purging.
On the afternoon of February 13, the expansion machine was debugged and started, and the three major units simultaneously increased the system load.
At 9:00 on February 14, the temperature of the distillation tower dropped to -175°C.
At 1:00 on February 15, the liquid level in the distillation tower began to appear. At 17:00, the liquid level of the main condensing evaporator of the distillation tower reached 98%, and the purity of liquid oxygen reached 99.96%, meeting the conditions for starting the pump for external delivery.
At present, with the continuous production of qualified oxygen products, the distillation tower is further purified, gradually meeting the requirements of subsequent sections. use. In the next step, the workshop will continue to optimize the process based on the characteristics of the device to ensure optimal device production.
Project Overview
Hubei Sanning synthetic ammonia raw material structure adjustment and joint production of 600,000 tons/year The ethylene glycol project (Phase I) is based on the synthetic ammonia production capacity of Sanning Company’s urea plant and Tiantian Company’s 520,000 tons/year. On the premise that the production capacity does not increase, the existing anthracite-based plant using atmospheric pressure intermittent production as raw material will be eliminated. Fixed-bed gasifier, atmospheric desulfurization, high-pressure ammonia synthesis urea plant and Tiantian Company’s ammonia synthesis unit and downstream urea and ammonium bicarbonate units. The estimated total investment of the project is 10 billion yuan. The new project will use Shenhua high-quality coal as raw material to produce 400,000 tons/year of ethylene glycol and 520,000 tons/year of synthetic ammonia; use sulfur as raw material to produce 800,000 tons/year of industrial-grade sulfuric acid.
Hubei Sanning Chemical Co., Ltd. is a coal-based chemical ethylene glycol project that fully implements the concept of circular economy development, selects energy-saving and environmentally friendly production routes, integrates advanced process technologies from many countries, and Intelligent control systems and equipment to achieve green, intelligent and intrinsically safe purposes. Hubei Sanning’s 600,000-ton coal-to-ethylene glycol project, which is nearing the end of construction, has automation and intelligence investment accounting for nearly 10%, far exceeding the proportion of all previous projects. As a life project for the transformation and upgrading of Sanning’s intelligent development, it adopts Lots of innovation.
Hubei Sanning Chemical Co., Ltd. was formerly known as Zhijiang County Fertilizer Factory and was founded in 1970. In 1993, it was transformed into a state-controlled joint-stock company as a pilot project. In 2001, it was reformed into a private enterprise through “two replacements”. In 2007, it became a controlling shareholder of Shanxi Jincheng Anthracite Mining Group Co., Ltd., a large state-owned enterprise. </p
