In recent years, a research institute of a petrochemical company and some production plants have adopted information-based means to establish a database system for evaluation of cracking raw materials, which integrates the evaluation data of cracking raw materials into the database system for scientific and effective management. By making the classification, filing, management, transfer and analysis of data normalized, systematic and professional and making efficient use of the evaluation data, the database system can play a full role in raw material procurement, mixing, processing and production scheme optimization.
