Successful Commissioning of 54,000 Nm3/h Air Separation Unit with Mannesmann Turbine in Anhui Jinmei Zhongneng Chemical Co., Ltd. Author/Source: Gas Separation Date: November 21, 2019 Clicks: 77 At 18:00 on November 19, the Mannesmann turbine unit of the 54,000 Nm3/h air separation project carried out by Zhejiang Industrial Equipment Installation Group Co., Ltd. in Anhui Jinmei Zhongneng Chemical Co., Ltd. was successfully commissioned; the warm-up speed, critical speed, operating speed within the normal range, and speed for shutdown sequences all met the design specifications. Regarding the successful trial operation of this unit, Jiang Zhanggen, the head of the Air Separation Department at Zhejiang Industrial Equipment Installation Group, said that the project will now enter the main trial operation phase. This equipment is also the largest imported unit owned by the client company, and its successful first start-up marks a milestone. Public information shows that the 600,000-ton synthetic ammonia intelligent upgrading project of Anhui Jinmei Zhongneng Chemical Co., Ltd. utilizes aerospace HT-L pressurized coal gasification, liquid expansion air separation, isothermal shift reaction, low-temperature methanol washing for desulfurization and decarbonization, liquid nitrogen washing for purification, and low-pressure ammonia synthesis technologies to build two sets of 300,000-ton synthetic ammonia production units. The 54,000 Nm3/h air separation unit of Zhongneng Chemical was designed and manufactured by Hangyang Gas Equipment Co., Ltd. The air compression unit is the largest power equipment in this facility; it consists of a turbine, an air compressor, and a booster. The air compression unit used is a multi-axis centrifugal compressor unit from German company Mannesmann, representing an important technical advancement that enables Zhongneng Chemical to achieve intelligent upgrades of its industrial equipment. On June 20, 2017, the intelligent upgrade and technical transformation project for Zhongneng Chemical’s 600,000 tons per year ammonia synthesis facility officially commenced. This project utilizes the advanced and mature domestic pressurized coal gasification technology, offering advantages such as lower investment costs, higher production efficiency, and reduced overall expenses. Once operational, the project will generate significant economic and social benefits, contributing to the enhancement of the company’s overall competitiveness. It is understood that Zhejiang Province Industrial Equipment Installation Group Co., Ltd. is a large-scale comprehensive installation enterprise group with **Grade 1 general contracting qualifications for petrochemical engineering construction, Grade 1 general contracting qualifications for mechanical and electrical engineering construction, Grade 1 specialized contracting qualifications for steel structure engineering, Grade 2 general contracting qualifications for building construction, and Grade 2 general contracting qualifications for metallurgical engineering construction. In the field of air separation plant construction, the company’s construction capacity has increased from 1 unit per year 20 years ago to over 20 units today; the scale of the plants it builds has risen from 3,000 Nm3/h to 90,000 Nm3/h. Its scope of operations has expanded from steel-related air separation projects to those in the chemical industry, enabling it to become a well-known brand nationwide.
