Multifunctional operation monitoring method for polythene production process

Abstract

The invention discloses a multifunction operation monitoring method for the production process of petrothene, which is realized by replying on three layers of architectures connected by Internet; the method has the advantages of simple network deployment, convenient upgrade, interconnection, update, and maintenance in implementation and application. Plant mode selection is common and standard. The method solves the problem that the current process units of petrothene are short of an omnibearing operation monitoring method and overcomes the defect that a DCS system can not directly realize various advanced monitoring techniques; and the architectures and the plant mode selection can be conveniently popularized and applied to other types of industry devices.

Description

technical field [0001] The invention relates to polyethylene production technology in the field of petrochemical industry, in particular to a multifunctional operation monitoring method for polyethylene production process. Background technique [0002] In the past two decades, China's petrochemical industry has developed by leaps and bounds. Taking synthetic resin at the end of the petrochemical production chain as an example, by the end of 2007, the production scale of synthetic resin ranked second in the world, and the scale of demand ranked first in the world, becoming a veritable world producer, consumer and importer. Vinyl resin accounts for about 50% of the total synthetic resin. Therefore, polyethylene production process and equipment is one of the most common and important equipment in petrochemical enterprises. [0003] There are many production processes of polyethylene resin, but no matter what kind of process, its production operation and equipment operation ar...

Problems solved by technology

However, due to the different purposes and functional design limitations of the DCS system itself, the dedicated control modules generated by various advanced monitoring technologies basically cannot be directly embedded into the DCS system for implementation.
