Successful ignition of low-temperature furnace drying for Boiler No. 4 in Xinjiang Tianye’s ethylene glycol project / Author/Source: Donghua Engineering Technology Co., Ltd. Date: 11-05-2019 Clicks: 119 On November 3, the low-temperature furnace drying process for Boiler No. 4, which is part of the auxiliary systems in Xinjiang Tianye’s 600,000 tons/year ethylene glycol production facility in its first phase, was completed successfully. Out of the 4 boilers in the project, 3 have already completed their drying and ignition processes successfully; the last one is expected to start its low-temperature drying and ignition on November 10. At present, the unit is operating normally, and the purging work for the air separation unit is also progressing in an orderly manner. The boiler system of Xinjiang Tianye Huihe New Materials Co., Ltd. serves as the source of steam for the main chemical processing units; it is an essential component for water, electricity, steam, and air supply in these chemical plants. To date, the boiler system has successfully completed the construction of all its main components and auxiliary systems, as well as individual unit tests, subsystem tests, and system integration tests. Thus, a milestone has been reached with the completion of testing and the establishment of a fully functional process flow in this facility. The successful completion of the low-temperature drying process for the boiler unit is an important step in bringing the engineering project online, as well as a key milestone in the production commissioning phase. It plays a role in subsequent tasks such as unit commissioning, purging of the high and low pressure steam systems, and commissioning of various machinery, marking the beginning of the gradual trial operation and eventual full-scale startup of the Xinjiang Tianye ethylene glycol project. 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 involves a facility for producing 600,000 tons of ethylene glycol per year. The planned area for this facility is over 2,200 mu, with a total investment of 8 billion yuan. The construction site is located in the Shihu Tan New Materials Industrial Park in Shihezi, Xinjiang (147th Regiment). Construction began in August 2017, with completion and operation scheduled for the end of 2019; once operational, the facility is expected to generate an annual output value of 4.2 billion yuan. The core process of the project utilizes the ethylene glycol production technology from syngas, developed by a consortium of High Chemistry and Donghua Technology.
