On June 30, the 1.2 million tons per year ethylene production unit of Guangdong Petrochemical’s integrated refining and chemical processing project was completed; this unit has now entered the stage of trial operation with feedstock introduction. The ethylene plant utilizes a set of patented ethylene technologies independently developed by Huanqiu Company. The facility is equipped with 6 liquid pyrolysis furnaces, each with a production capacity of 200,000 tons per year, which represents the highest capacity per furnace of its kind in China at present.
The ultra-high pressure steam used for purging in Guangdong Petrochemical’s 1.2 million tons/year ethylene plant comes from power boilers, with a pressure of over 4.0 MPa and a temperature of 420°C. At 2 p.m., the ethylene plant began to introduce steam to warm the pipes; warning lines and signs were set up at the site, and the safety department assigned personnel to conduct regular inspections there to prevent anyone from entering the area where cleaning was taking place and suffering burns. To ensure the smooth progress of steam pipeline purging, the project team took proactive measures in advance, carefully formulated a purging plan, and organized personnel in charge of technology, safety, quality inspection, etc. to examine and confirm the purging conditions. They also made thorough arrangements for the organization of steam purging processes and the technical aspects involved, so as to guarantee that the purging of each section of the pipeline could be carried out smoothly. At the same time, experienced process technicians are organized to inspect all the steam pipes involved in the purging process, to ensure that it is carried out safely and under control. The purging of steam pipelines is the final step to ensure their cleanliness; it also serves as a check on the quality of the construction work carried out on these pipelines. It prepares everything for the successful commissioning and safe operation of the three units in the ethylene plant, marking another crucial step forward in bringing the project to operational status.
Construction of the 19-kilometer pipeline tunnel project is completed
On June 30, 2021, at a time when the whole nation was celebrating the centenary of the founding of the Communist Party, the ongoing projects at Guangdong Petrochemical also reached an inspiring milestone. With the detailed design of the \"cover image\" for all 204 main units completed, the engineering design work for Guangdong Petrochemical was successfully finished, and the project has entered a new phase of construction. All cadres and employees, along the shores of the South China Sea, have written a new chapter for this era with their practical actions, embodying the spirit of \"remaining loyal to the Party throughout a century of glory, and striving forward on a new journey.\"
Guangdong Petrochemical’s desalinated water system was successfully commissioned in a single trial run. Mud Network, 2022-02-27 08:19: The desalinated water station and condensate purification unit of Guangdong Petrochemical’s integrated refining project were able to produce secondary desalinated water right from the start. As of February 23, approximately 5,000 tons of water had been produced to supply water for flushing deaerators and acid cleaning of boilers at the power center. Upon receiving the task to start trial operation of supplying qualified deionized water to the Power Center on February 22, the Public Works Department of Guangdong Petrochemical collaborated with the general contractor Kunlun Engineering Company and other relevant project parties to carry out all the tasks related to this trial operation as planned. All departments of Guangdong Petrochemical work together in coordination, make rational use of the relevant equipment to safely receive acids and bases, thoroughly transform and regenerate the ion exchange resin, thereby producing first-grade deionized water. After being treated by a mixed ion exchanger, the primary deionized water is converted into qualified secondary deionized water, indicating the successful commissioning of the deionized water system in just one attempt. Meanwhile, in accordance with production requirements, the demineralized water system of Guangdong Petrochemical supplies water to filters at all levels throughout the plant, including the floating bed with two chambers and dual functionality for filtration and flushing, the carbon remover, the intermediate water tank, and the floating bed with two chambers and dual functionality on the cathode side; the designed supply rate is 4,000 tons per hour.
