The #2 unit of the air separation plant supporting Xinjiang Tianye’s ethylene glycol production project was successfully commissioned. Author/Source: Coal Chemical Engineering 114 Forum; Date: 2020-06-02; Clicks: 4. Recently, the #2 unit of the 2×90,000 Nm3/h air separation plant, which is part of the first phase of Xinjiang Tianye (Group) Co., Ltd.’s project to produce ethylene glycol from syngas at a capacity of 1 million tons per year – specifically the 600,000 tons per year ethylene glycol production line – was successfully commissioned. This unit has begun producing oxygen and nitrogen, thereby providing the necessary materials for the subsequent instrument calibration, replacement of the production systems, and pilot operations of the coal chemical plants in this project, thus accelerating the progress of project construction. It is understood that the air separation system for Xinjiang Tianye’s 600,000 tons per year ethylene glycol production project consists of 2 sets of 90,000 Nm3/h units manufactured by Hangyang Co., Ltd., along with 1 backup liquid nitrogen storage and vaporization system. The cold box of these units is 74 meters high and is divided into lower, middle, and upper sections. Each unit has an oxygen production capacity of 90,000 Nm3/h and a nitrogen production capacity of 40,000 Nm3/h. This is the largest air separation system in terms of scale and production capacity introduced in Xinjiang to date; it also represents advanced domestic large-scale air separation systems, with its patented technology reaching world-leading levels. The successful commissioning of this air separation unit marks the full transition of the auxiliary systems for Xinjiang Tianye’s 600,000-ton ethylene glycol project from the construction phase to the trial production phase, thereby providing the necessary materials and safety guarantees for the subsequent commissioning of the core production units. Xinjiang Tianye Huihe New Materials Co., Ltd. has an annual production capacity of 1 million tons of ethylene glycol from syngas, and its core manufacturing process makes use of patented technology for producing ethylene glycol from high-quality chemical syngas. The first-phase project, a 600,000 tons per year facility for producing ethylene glycol from syngas, is located in the Shihu Tan New Materials Industrial Park, Group 147, Shihezi City, in the Eighth Division. It is the first project to be developed in this industrial park. The project covers an area of 2,200 mu, with a total investment of 7.99 billion yuan. It represents a new starting point for Xinjiang Tianye Group as it strives to pursue further development and achieve a valuation of 100 billion yuan for the company. Construction of the first phase began in August 2017. In October 2017, the project’s gasification technology sector entered into a contract with Shanxi Yangmei Chemical Machinery (Group) Co., Ltd. for four sets of 6.5MPa Jinhua furnaces model 3.0. As a key project at the corps level, the Shihu Tan New Materials Industrial Park is planned to cover an area of 9.98 square kilometers, with an investment of around 70 billion yuan. Tianye Group is responsible for its planning and construction. The first phase of the project, which involves the production of 600,000 tons of ethylene glycol, along with some supporting infrastructure in the park, began construction in August 2017; the entire park is expected to be completed and put into operation by the end of 2019. As planned, once the 600,000-ton dialcohol production project in the first phase of the park is completed, subsequent projects such as coal-based ethanol production and related new material initiatives, as well as polyester production and its associated upstream and downstream projects, will be carried out in sequence and developed in a coordinated manner. It is understood that the project will enter the phase of large-scale installation in mid-May this year, and will be fully completed and put into operation by the end of the year, with an estimated annual output value of 4.2 billion yuan.
