Mainly it discusses two problems: software instruments of viscosity and flash point using neural networks and operation optimization on the atmospheric and vacuum towers using NLJ method.
Then based on practice of the project it is introduced design of process management and operation directing system in extract atmospheric tower and design of project database.
然后结合课题实际介绍了常压塔系统工艺管理和操作指导系统的设计、项目数据库的设计；

The FBCD can be used continuously or for batch operation, not only under atmospheric pressure, but also under vacuum or positive pressure.
