Abstract: Web-based crude oil fast-evaluation software was developed. At the software architecture level, it is composed of modules of user application, near infrared (NIR) spectrum library management, crude oil modeling, crude oil fast-evaluation model, library management and user management. The software has centralized system for maintenance and release of model database, management of spectral database and evaluation database, and upgrading the algorithm of crude oil fast evaluation. Through comprehensive application of the upgraded algorithm, calculation speed and recognition accuracy of prediction results can be significantly improved. NIR spectroscopy database of two refineries were built through collecting their regular processed crude oil’s NIR spectra. Then, the above database and Research Institute of Petroleum Processing (RIPP) database were combined to establish the fast evaluation analysis model to monitor and analyze crude oils in different refineries. It was found that NIR validation results are reliable.
