Comprehensively discusses the oil refining technology, a simple analysis of the mechanism of oil refining technology, selective, classification and process.It is discussed how to foster strengths and circumvent weaknesses, make in practice, the oil refining to suit the requirements of stable and efficient, economical and practical.Finally, this paper expounds the various refining process operating essentials.palm oil mill?,Oil colour and lustre is one of important sensory index to evaluate the quality of the oil, is also a need to strictly control the quality of the oil refining process.In this paper, the factors that affect oil decoloring effect in the process of oil refining is analyzed, and proposed the corresponding control measures, so as to relevant enterprises to further increase the rate of oil refining, reduce loss, improve product oil colour and lustre is to provide the reference.draught fan?,Full automation system application in the oil refining process can achieve fine operation, reduce the production cost.Adoption of new technology such as anhydrous soap, secondary, enzymatic degumming, nano and capture technology, to capture as much as possible in distillate of VE and enrichment of fatty acids, natural products, produce high added value to reduce waste water discharge is an effective way to improve the benefit of oil refining.6.Oil refining is an important link in oil processing process, there are many important parameters in oil refining process is directly related to the product quality.Oil refining production line intelligent monitoring system for the key parameters in the process of oil refining and process control requirements, adopt the method of computer + intelligence I/O module for real-time, on-line monitoring of these parameters, through the corresponding intelligent control strategy to meet the technological requirements of oil refining, ensure the safety of the production process to work effectively, improve work efficiency, improve…
