Recently, the first branch of Ningxia Coal and Olefin Co.
, Ltd.
completed the first localized transformation of imported control system, and upgraded a set of polypropylene device DCS to a domestically-made ECS700 control system
.
This transformation is one of the Class A projects of Olefin No.
1 Branch's major overhaul in 2021
.
Since a set of polypropylene plant DCS has been in continuous operation for 11 years, there are problems such as heavy load, high failure rate, and difficulty in purchasing spare parts.
The localization of the control system this time improves the logical control function of the original control system, realizes the effective early warning of the equipment performance and key parameters of the polypropylene plant, and further improves the analysis and sorting function of the alarm information during the production and operation of the plant, and automatically shields Invalid alarm, to provide technical support for the transformation of advanced control system in the future
.
Feng Jiangang, director of the instrument workshop of the Olefin No.
1 Branch of Ningmei Coal Company, said that the use of domestic DCS can get rid of the restriction that the system can only be upgraded from the original factory.
The performance of the domestic control system hardware is improved, and the subsequent operating cost is reduced by 50% compared with imported products
.
Domestic controllers and network equipment have improved the safety of industrial control networks and laid the foundation for the localization of other devices throughout the plant
In the next step, they will build an advanced alarm management system and control system platform on the domestic DCS, analyze and sort the alarm information generated during the production process, automatically shield invalid alarms, reduce the number of operator confirmations and interventions, and pass automatic adjustments.
