The air separation unit for Hubei Sanning Chemical’s 600,000-ton ethylene glycol project has been successfully commissioned! Author/Source: Coal-based New Materials Date: 2021-02-22 Clicks: 13 Sanning Chemical’s No. 1 air separation unit produced oxygen of 99.96% purity, meeting the required standards for delivery. At 17:00 on February 15th, the No. 1 air separation unit in the air separation workshop of Shibaoshan New Materials Branch produced oxygen with a purity of 99.96%, which met the specified quality requirements. The unit began blasting and purging on May 18 last year, and has successively completed a series of preparatory tasks such as the turbine startup, coupling tests of the three main machines, and a thorough purge of the unit. On the afternoon of February 13, the expansion machine was commissioned and started up, with the three units simultaneously increasing 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, a liquid level began to appear in the distillation tower. At 17:00, the liquid level in the main condensation evaporator of the distillation tower reached 98%, and the purity of liquid oxygen reached 99.96%, meeting the conditions for starting the pump to transport the product. At present, as qualified oxygen products are continuously produced and the distillation towers are further purified, the requirements of subsequent processing stages are gradually met. Next, the workshop will continuously optimize the manufacturing process based on the characteristics of the equipment, to ensure optimal production performance.
