Core Viewpoint - The successful commissioning of a new 500,000 tons/year propane deasphalting unit at Karamay Petrochemical Company marks a significant advancement in the company's lubricating oil structural adjustment projects, enhancing production capabilities and optimizing product structure [1]. Group 1: Project Details - The propane deasphalting unit was successfully commissioned on August 15, 2023, and has already processed 1,000 tons of material with stable production operations [1]. - This unit is part of a series of key construction projects aimed at adjusting the lubricating oil structure, following the commissioning of a high-pressure hydrogenation unit in 2019 and a white oil hydrogenation unit in 2022 [1]. - The construction of the unit began on April 28, 2024, with an expected completion date of June 30, 2025 [1]. Group 2: Technical Specifications - The unit occupies nearly 10,000 square meters and consists of subcritical extraction, supercritical solvent recovery, and flashing of asphalt-deasphalt oil [1]. - It primarily uses paraffin-based vacuum residue oil as raw material and employs supercritical extraction technology to produce deasphalted oil [1]. Group 3: Production Impact - The new unit will optimize the feed for the company's existing three high-pressure hydrogenation units, increasing the production of bright stock and high-end white oil products [1]. - It will also enhance the production capacity of hard asphalt products, thereby optimizing the company's lubricating oil product structure [1].
