Recently, Sinopec Hainan Refining & Chemical Co., Ltd. (referred to as “Hainan Refining & Chemical”) held a handover ceremony for some of the main facilities in the chemical processing area and refining area, as well as certain supporting projects, at the 1 million-ton ethylene project site located in the Yangpu Economic Development Zone. The main items for which procedures are being handled collectively this time include 3 major production units such as light hydrocarbon recovery, pyrolysis gasoline hydrogenation, and aromatic extraction, along with 14 supporting facilities. To date, 48 individual projects, including the power center and light hydrocarbon recovery units, have been handed over from the construction phase to operational use. The personnel involved in these projects are accelerating tasks such as pipeline purging, instrument calibration, and joint commissioning in order to prepare for startup trials.
It is reported that Hainan Refining and Chemicals’ million-ton ethylene project and the refinery expansion project are key projects in Hainan Province and Sinopec; the total investment in these projects amounts to over 28 billion yuan. To date, more than 23 billion yuan has been invested, with the overall construction progress exceeding 97%. Once completed, these projects will help foster the development of downstream industries such as advanced agriculture, green chemicals, and tourism and health care, with a total value of over 100 billion yuan. Next, Hainan Refining & Chemical will strictly implement epidemic prevention and control measures, advance the project construction goals in an orderly manner, focus on completing the remaining tasks and addressing the issues identified through the “three inspections and four determinations” process, carry out intermediate handover procedures for all units with high quality, and complete tasks such as cleaning and purging of the unit systems to ensure smooth commissioning of the ethylene project. This will help to ensure that the project is operational as soon as possible, thereby contributing to the development of Hainan Free Trade Port.
On June 29, the mid-term delivery ceremony for the main facilities in the chemical processing area and oil refining area, as well as some supporting projects, of Hainan Refining & Chemical’s 1 million-ton ethylene project located in the Yangpu Economic Development Zone was held. The main units involved in the mid-term delivery include 3 primary units such as the pyrogas hydrogenation unit, the aromatic extraction unit, and the light hydrocarbons recovery unit, along with 14 supporting projects. To date, 48 main units, including the power center, the C8 complex, and the light hydrocarbons recovery unit, have moved from the construction phase to the production preparation phase. Operators are accelerating tasks such as pipeline purging, instrument calibration, and joint commissioning in order to prepare for startup trials.
On July 28, 2021, the Sinopec companies based in Hainan jointly released the white paper titled \"Sinopec’s Social Responsibility Report in Hainan\" for the first time. The white paper states that the investment in the expansion project for ethylene production and oil refining at Sinopec Hainan Refining & Chemical Company, with a capacity of 1 million tons per year, amounts to approximately 28.1 billion yuan. The project is under construction in a safe and efficient manner, and it is expected to begin trial operations on September 30, 2022. It is estimated that once the project is completed and put into operation, it will add around 20 billion yuan in output value for the ethylene sector and 5 billion yuan in tax revenue, while driving output values in downstream industries worth hundreds of billions of yuan. Currently, Sinopec has a comprehensive crude oil processing capacity of 9.2 million tons per year in Hainan, an aromatic hydrocarbons production capacity of 1.6 million tons per year, as well as a refined oil sales capacity of 1.6 million tons per year. Since 2006, the Sinopec enterprises based in Hainan have paid a total of over 102 billion yuan in various taxes and fees to the province, ranking first in Hainan in terms of tax payments for 14 consecutive years.
At 20:58 on June 13, the first ignition of Boiler No. 1 in the power center of Hainan Refining & Chemical Company’s 1 million-ton ethylene and refining expansion project was successful! With this, the steam system is now fully ready for operation, and Hainan Refining & Chemicals has moved from the project construction phase to a new stage of production commencement. It is understood that the Hainan Refining, Chemicals and Power Center, as the core steam supply unit for the entire ethylene plant, not only ensures the balance of steam usage across the plant but also provides essential steam support for the purging and commissioning of the pipelines in the ethylene project. The power center is equipped with 3 ultra-high-pressure boilers of 220 t/h each; each boiler can produce 220 tons of ultra-high-pressure steam per hour. Through temperature reducers and pressure regulators, as well as drive turbines, it is capable of generating high-, medium-, and low-pressure steam, and it also has the capability to generate electricity. The boiler features an advanced combination of low-NOx gas burners, SCR denitration, and FGR flue gas recirculation; using clean gas as fuel, it ensures that flue gas emissions meet ultra-clean standards, with the NOx concentration being only 17.5% of the national standard.
On December 1, 2020, the civil engineering work for the Power Center was the first to begin on this site
