Abstract
Disclosed are high-pressure polymerization methods and systems using optimized operation sequence logic established at least partly from an analysis of a database containing data of previous operations. The optimized operation sequence logic and collected current process and system data are used to automate the operation of a high pressure ethylene polymerization process and unit.
Claims24
A method for operating a high pressure ethylene polymerization unit, comprising:
- (I) collecting data from previous operations;
- (II) building a database including the collected data of previous operations;
- (III) analyzing the database;
- (IV) establishing computer coding embodying an optimized operation sequence logic;
- (V) collecting real-time data of a current operation;
- and
- (VI) conducting one or more next steps of the current operation according to the optimized operation sequence logic and current data at least partly by using an automated computer system.
