The Zhoushan Green Petrochemical Base’s 40 million tons/year refining and chemical integration project (Phase I + Phase II) is currently the largest investment single industry project in the world. Since May 2019, the first phase of Zhoushan Green Petrochemical Base has been put into operation, processing 23.06 million tons of crude oil in 2020.
Yushan Island was once a small island isolated on the west side of Daishan Mountain. Islanders have made a living from fishing for generations. Starting in 2015, the Zhoushan Green Petrochemical Base of Zhejiang Petrochemical Co., Ltd. settled on this small island, completely changing its development trajectory. In 5 years, one refining facility and distillation tower were built one after another. On December 31, 2019, the first phase of the project construction was fully put into operation. What was once Yushan has now become an important dragon in the petrochemical industry. Yushan Island in Zhoushan, which is more than 20 square kilometers, is advancing a huge project that will go down in history. With the full service support of all parties, in more than 4 years, Zhoushan Green Petrochemical Base has completed the first phase of project construction that took 10 years to complete. The first phase of the 20 million tons/year refining and chemical integration project has fully reached production in 2020. The annual output value is 74.8 billion yuan, accounting for nearly 50% of Zhoushan’s total industrial output value in 2020.
The 40 million tons/year refining and chemical integration project (Phase I + Phase II) of Zhoushan Green Petrochemical Base is currently the largest single industry investment in the world project. In 2020, 23.06 million tons of crude oil were processed. In July 2020, Zhejiang Petrochemical Co., Ltd., a key enterprise in the base, obtained the country’s first non-state-owned trade export qualification for refined oil; on November 18, 2020, the company obtained another 1 million tons of refined oil export quota; by 2020 At the end of December this year, in just over a month, the company exported 850,000 tons of refined oil.
“The second phase of the 20 million tons/year refining and chemical integration project is advancing faster than the first phase.” The relevant person in charge of the Zhoushan Green Petrochemical Base Management Committee said that on January 2, 2021, the second phase of the base After more than six months of intensive construction, the reactor frame of the residual oil hydrogenation unit of the phase 1 project was finally hoisted and capped successfully. The Zhoushan Green Petrochemical Base has currently completed a total investment of nearly 130 billion yuan, and will complete fixed asset investment of approximately 38.6 billion yuan in 2020. According to the established plan, Zhoushan Green Petrochemical Base will focus on the third phase of development, continue to expand the scale of the industry, and refine and strengthen the midstream and downstream petrochemical industry chain. Ultra-high production capacity does not mean environmental pollution. Zhejiang Petrochemical Phase I insists on putting green first from the design stage. The production plant mainly uses desulfurized clean dyes such as self-produced syngas and dry gas, which fundamentally reduces sulfur dioxide emissions. At the same time, special UOP ultra-low nitrogen burners are introduced into major production units such as atmospheric and vacuum pressure, continuous reforming, and aromatic hydrocarbon combination. , further denitrify the production process to ensure that pollutant emission levels are better than the most stringent environmental standards. In recent years, the trend of “reducing oil and increasing chemical” in my country has been obvious. Refining and chemical companies are shifting from mainly producing refined oil and bulk chemical raw materials to producing more high value-added oil products and high-performance chemical products to extend the industrial chain, thereby further expanding the refining industry. development space for the chemical industry. Zhejiang Petrochemical has three product chains: comprehensive balanced refining, ethylene and aromatics. It produces a large amount of aromatic ethylene raw materials, produces gasoline and jet fuel in moderate quantities, and produces less diesel. It has a deep crude oil processing degree, a high proportion of chemicals, and strong integration capabilities.
As of now, the total yield of refined oil in the first phase of the project is 35%. It is expected to be reduced to 29% after the second phase is put into operation, which is far lower than the 60% level of traditional refineries. It has truly achieved the goal of “draining” crude oil. Squeeze it out.” Thanks to these stringent environmental protection and production measures, when you set foot on Yushan Island now, although you can see a lot of chimneys at first glance, there is no pungent feeling in the air. Looking from afar, the huge factory area like a future world contrasts with the blue sea in the distance, forming a wonderful picture.
Looking down from the observation deck at the highest point of Yushan Island, the second phase of the huge project is under construction in full swing. There is a constant flow of various engineering vehicles, and new equipment is installed every day and every week. , a new factory building was built. It is expected that the second phase of the project will be completed by the end of 2021. In the future, Yushan Island will also build a green petrochemical industrial park, introduce domestic and foreign upstream and downstream processing enterprises, expand the petrochemical industry chain, and further enhance its competitiveness in the international market. It is understood that after Zhejiang Petrochemical’s 40 million tons/year refining and chemical integration project reaches full production, the annual output value is expected to exceed 250 billion yuan, which can drive 600 billion yuan in the upstream and downstream industrial chains. The project can directly provide more than 70,000 jobs during the construction period and more than 10,000 jobs during the operation period.
