Abstract

The crude distillation unit is one of the energy-intensive processes in the refinery. This is because of the crude preheater that suffers from excessive energy loss due to the use of air in the combustion furnace. Alternatively, fuel combustion by enriched oxygen can improve heat efficiency, minimize fuel consumption and reduce emissions. In this paper, enriched oxygen has been simulated by UniSim for preheating Kuwaiti crude in one of the distillation columns in the Clean Fuels Project. Results show that the use of 30 mol% of concentrated oxygen reduced fuel consumption by 5%. Carbon dioxide emissions were also minimized by 22,240 tons per year. A membrane system made from perfluoropolymer was simulated for the production of 5,298 tons of enriched oxygen (per day) and it required an area of 39,000 m 2 with a capital investment of 6.9 million $.

富氧用于石油炼制中原油预热

原油蒸馏装置是炼油厂的能源密集型工艺之一。这是因为粗预热器由于在燃烧炉中使用空气而遭受过度的能量损失。或者，通过富氧燃烧燃料可以提高热效率，最大限度地减少燃料消耗并减少排放。本文用UniSim模拟了清洁燃料项目中一个蒸馏塔中的富氧预热科威特原油。结果表明，使用30mol%的浓氧可使燃料消耗减少5%。二氧化碳排放量也减少到每年22240吨。模拟了一个由全氟聚合物制成的膜系统，用于生产5298吨富氧（每天），该系统占地39000平方米，资本投资690万美元。

期刊介绍： The purpose and scope of the International Journal of Thermodynamics is · to provide a forum for the publication of original theoretical and applied work in the field of thermodynamics as it relates to systems, states, processes, and both non-equilibrium and equilibrium phenomena at all temporal and spatial scales. · to provide a multidisciplinary and international platform for the dissemination to academia and industry of both scientific and engineering contributions, which touch upon a broad class of disciplines that are foundationally linked to thermodynamics and the methods and analyses derived there from. · to assess how both the first and particularly the second laws of thermodynamics touch upon these disciplines. · to highlight innovative & pioneer research in the field of thermodynamics in the following subjects (but not limited to the following, novel research in new areas are strongly suggested): o Entropy in thermodynamics and information theory. o Thermodynamics in process intensification. o Biothermodynamics (topics such as self-organization far from equilibrium etc.) o Thermodynamics of nonadditive systems. o Nonequilibrium thermal complex systems. o Sustainable design and thermodynamics. o Engineering thermodynamics. o Energy.
