On December 1, the large-scale air separation plant of the 500,000-ton methanol project of Henan Zhongyuan Dahua Group Co., Ltd. was successfully tested at one time, indicating that the company's coal chemical project has made significant progress.
The design capacity of the large-sized air separation plant in Zhonghua Dahua Coal Chemical Industry is to produce 52,000 cubic meters of oxygen, 9,000 cubic meters of ultra-high pressure nitrogen, 32,100 cubic meters of pressure nitrogen, and 20,000 cubic meters of low-pressure nitrogen per hour. This is the largest empty capacity independently designed and manufactured in China. Sub-device. In order to ensure that the air separation unit achieves a successful start, the company pays close attention to all aspects of design, construction, installation and commissioning. In the design stage, they started from the dozens of professional integration points such as technology, machinery and equipment, chemical pipelines, electrical equipment, instrumentation, telecommunications, architecture, etc., in order to strengthen the contact with the design unit, modify the design details, and ensure the design quality. In the construction and installation, they formulated a rolling construction plan, rigorous construction regulations, implemented safety, quality, and technical disclosure management methods, and promoted the construction schedule to ensure the construction quality. In the test run, they followed the “single test run. The overall requirements for the linkage test should be stable, and the overall requirements for chemical feedstuffs should be stable. The air compressor test, cold box leak check, and expander test were all completed. The single test run and linkage test run were carried out to provide smooth operation of the air separation unit system. Technology and equipment guarantees.
