Core Viewpoint - The development of energy-saving and efficient crude oil distillation technology, specifically the "precise separation of crude oil distillation based on energy conservation," has been recognized as a significant advancement in the refining industry, leading to improved efficiency and reduced energy consumption [1][5]. Group 1: Technological Challenges - The traditional crude oil atmospheric distillation technology is energy-intensive due to high processing volumes and temperatures, with actual flash distillation efficiency being less than 75% [2][3]. - Existing technologies, such as those from Shell and KBC, face common issues of increased energy consumption and reduced quality of wax oil, highlighting the need for innovative solutions [3]. Group 2: Innovative Solutions - A research team has proposed a new mass transfer model and developed several innovative devices, including the NS distillation deep extraction device and high-efficiency composite tower plates, which significantly enhance mass transfer efficiency [4]. - The new technology has improved diesel and wax oil yields by 3% and 4-6%, respectively, while reducing system energy consumption by 20% compared to similar foreign technologies [4]. Group 3: Industrial Application and Impact - The developed technology has been implemented in 43 crude oil distillation systems across major Chinese oil companies, demonstrating significant energy savings and efficiency improvements [6]. - Over the past three years, the application of this technology in three companies has resulted in an additional sales revenue of 3.37 billion yuan and tax contributions of 850 million yuan [7].
