News	Kokel, Nicolas S-Oil Shaheen 2025/03/13 09:50 AM S-Oil Announces 55% Completion of Ulsan’s $7 Billion Shaheen Petrochemical Project View Main Message Construction is under way for S-Oil's $7 billion Shaheen petrochemical project in Ulsan (Credit: S-Oil) Ulsan, South Korea – February 17, 2025 – S-Oil, a leading South Korean refiner, has announced that its $7 billion Shaheen petrochemical project in Ulsan has reached 55% completion in engineering, procurement, and construction. This major initiative, featuring one of the world’s largest integrated steam crackers, is on track for mechanical completion in the first half of 2026, with commercial operations starting in the second half. Utilizing thermal crude-to-chemicals (TC2C) technology developed with Saudi Aramco and Lummus Technology, the project will produce 1.8 million tons of ethylene annually, doubling S-Oil’s petrochemical output to 25% and boosting South Korea’s economy with up to 17,000 jobs during peak construction. #soil #aramco #lummus #southkorea #korea #shaheen #tc2c #crudeoiltochemicals #oiltochemicals #steamcracking #ethylene #ulsan
Operations	Kokel, Nicolas S-Oil Shaheen 2025/03/13 07:31 AM Shaheen TC2C Project Mass Balance completed. View Main Message The Shahen TC2C Project Mass Balance has been completed. The TC2C Plant will import 46,000 bpd of Arab Light crude oil, corresponding to 2,300,000 tonnes annually. However, in order to obtain the announced product quantities (1,800,000 tonnes of ethylene, 770,000 tonnes of propylene, 200,000 tonnes of butadiene, and 280,000 tonnes of benzene) our calculation based on typical cracking yields show that the feedstock needs to amount to almost 5 million tonnes. The cracker will use ROG so that certainly some ethane will be additionally consumed by the cracker, but the feedstock balance reaquired for the precise product quantities is made of 150,000 tonnes of ethane, 1,300,000 tonnes of LPG (C3/C4 = 1:1 ratio) and 3,500,000 tonnes naphtha. Therefrom, 275,000 tonnes of LPG and 1,350,000 tonnes of nahptha will be provided by the TC2C plant. We assume that the supplemental feedstock will be imported, unless additional crude oil will be imported and processed with conventional distillation units. As this is a TC2C demonstration project, it is assumed that only the theoretical quantities of pygas and pyoil originating from the TC2C provided feedstock to the cracker will be recirculated to the TC2C hydrocracking and hydroreating units (270,000 from 475,000 tonnes of pygas, and 65,000 from 113,000 tonnes of fuel oil). In reality, the sizing of the various hydroprocessing/hydrotreatment units maybe different, but absent confirmation on units capacities, this is our best educated guess. #tc2c #shaheen #massbalance #crudetochemicals #crudeoiltochemicals #c2c #tc2c #cotc #aramco #soil #southkorea
News	Kokel, Nicolas S-Oil Shaheen 2025/03/11 05:40 AM Aramco affiliate S-OIL to build one of the world’s largest petrochemical crackers in South Korea View Main Message Saudi Arabian Oil Co., DHAHRAN, 17^th Nov 2022, Aramco affiliate S-OIL to build one of the world’s largest petrochemical crackers 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 maximize the crude to chemicals value chain. The $7 billion Shaheen project aims to convert crude oil into petrochemical feedstock and would represent the first commercialization 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. #shaheen #soil #petrochemicals #tc2c #oiltochemicals #crudeoiltochemicals #southkorea #aramco #steamcracker #ulsan #thermalcrudetochemical #naphtha
