據(jù)油氣新聞網(wǎng)11月17日報道，沙特阿美(Aramco)正在韓國進行有史以來最大的一筆投資，通過旗下子公司S-OIL開發(fā)全球最大的煉油一體化石化蒸汽裂解設備之一，這符合該公司將原油到化學品價值鏈最大化的戰(zhàn)略。

耗資70億美元的Shaheen項目，旨在將原油轉化為石化原料，這將是沙特阿美和Lummus Technology公司的TC2C熱原油轉化為化學品技術的首次商業(yè)化，該技術可提高化學品產(chǎn)量并降低運營成本。

此前，該石化擴建項目的第一階段投資40億美元，于2018年完成。

位于S-OIL的蔚山現(xiàn)有工廠的新工廠，計劃每年生產(chǎn)320萬噸石化產(chǎn)品，并包括一個生產(chǎn)高價值聚合物的設施。該項目預計于2023年開工，2026年完工。

蒸汽裂解裝置將加工原油加工的副產(chǎn)物，包括石腦油和廢氣，以生產(chǎn)乙烯——一種用于制造數(shù)千種日常用品的基礎石化產(chǎn)品。該工廠還有望生產(chǎn)丙烯、丁二烯和其他基本化學品。

阿美石油公司總裁兼首席執(zhí)行官Amin H Nasser表示，受亞洲新興經(jīng)濟體消費增長的推動，全球石化行業(yè)的格局正在迅速變化，需求增長預計將加速。這就是為什么S-Oil的Shaheen能夠滿足該地區(qū)關鍵行業(yè)對所需材料不斷增長的需求。通過阿美石油公司的熱原油轉化為化學品技術的首次商業(yè)化，進一步整合煉油和化學工藝，我們的目標是創(chuàng)造一個更高效、更有競爭力和可持續(xù)的增長平臺，同時為進一步的下游擴張鋪平道路。

沙特阿美下游高級副總裁Mohammed Y Al Qahtani表示，Shaheen希望不僅成為韓國S-OIL公司的改變者，也希望成為全球化學品業(yè)務的改變者，能夠以更高效、更低能源密集型的方式加工更多種類的原料。該項目是沙特阿美熱原油化工技術的首次大規(guī)模部署，并展示了通過更好的設計，如何能夠為向更高效、更可持續(xù)的生產(chǎn)流程過渡作出貢獻。

新的蒸汽裂解裝置計劃使用混合原料，在整體效率和性能方面優(yōu)于石腦油裂解裝置。項目一旦完成后，S-OIL的化學品產(chǎn)量（基于產(chǎn)量）可能會翻番，達到25%，這表明了這項尖端技術的影響，補充了阿美石油公司將其液體化學品產(chǎn)能提高至每天400萬桶的戰(zhàn)略。

沙特阿美是S-OIL的大股東，通過其子公司沙特阿美海外公司(Aramco Overseas company BV)持有63%以上的股份。

Aramco announces its biggest investment in South Korea

Aramco is making its biggest ever investment in South Korea to develop one of the world’s largest refinery-integrated petrochemical steam crackers through its S-OIL affiliate, in line with the company’s strategy to maximise the crude to chemicals value chain.

The $7 billion Shaheen project aims to convert crude oil into petrochemical feedstock and would represent the first commercialisation of Aramco and Lummus Technology’s TC2C thermal crude to chemicals technology, which increases chemical yield and reduces operating costs.

It follows an earlier $4 billion investment into the first phase of the petrochemical expansion completed in 2018.

Located at S-Oil’s existing site in Ulsan, the new plant is planned to have the capacity to produce up to 3.2 million tons of petrochemicals annually and include a facility to produce high-value polymers. The project is expected to start in 2023 and be completed by 2026.

The steam cracker is expected to process by-products from crude processing, including naphtha and off-gas, to produce ethylene — a building block petrochemical used to make thousands of everyday items. The plant is also expected to produce propylene, butadiene and other basic chemicals.

Aramco President & CEO Amin H Nasser said: “The global petrochemical landscape is rapidly evolving with demand growth anticipated to accelerate, driven in part by rising consumption from Asia’s emerging economies. That is why S-Oil’s Shaheen is well positioned to meet rising demand for the materials that will be required across the region’s key industries. By further integrating refining and chemical processes through the first commercialization of Aramco’s thermal crude to chemicals technology, we aim to create a more efficient, competitive and sustainable platform for growth, while paving the way for further downstream expansion.”

Aramco Senior Vice President of Downstream Mohammed Y Al Qahtani said: “Shaheen aspires to be a gamechanger not only for S-OIL in South Korea, but also for our global chemicals business, allowing us to process a greater range of feedstocks in a more efficient and less energy-intensive way. The project represents the first large-scale deployment of Aramco’s thermal crude to chemicals technology and shows how, through better design, we can contribute to the transition to more efficient and more sustainable production processes.” 

The new steam cracker is planned to use mixed feedstocks, outperforming naphtha-based crackers in terms of overall efficiency and performance. Upon project completion, S-OIL chemical yield based on volume could almost double to 25%, which demonstrates the impact of this cutting-edge technology, complementing Aramco’s strategy to expand its liquids to chemicals capacity to up to 4 million barrels per day.

Aramco is the majority shareholder of S-OIL, holding more than 63% of the company’s shares through its Aramco Overseas Company BV subsidiary.
