Coking industry is complex process smelting, chemical in one, the production environment is bad, the temperature, pressure and flow control loop and the requirements are relatively high, and with the growing awareness of environmental protection, and to improve environmental standards, coking industry process control system using DCS is the current trend.

Decentralized control system DCS to achieve the following functions of the system:

- coal blending system (coal slot DAS, coal transportation control and protection system, automatic control system, automatic proportioning of raw coal moisture monitoring system, mill control, pulverized coal conveying system control and protection etc.);

- coking system (coke oven DAS, coke oven heating gas flow and pressure cascade control system, air mixed combustion system, coke oven collector pressure control, coke oven basement gas concentration monitoring and basement ventilation machine interlock control system etc.);

Cold drum system (primary cooling and final cooling DAS, gas collecting duct pressure blower and hydraulic coupling control, gas duct recirculation flow control (blower minimum flow control) system, the water in the system of DAS, SCS, DAS, electric catcher electric TRAP sequence control system SCS, ESD);

- chemical production system (desulfurization system DAS, ammonia removal system DAS, benzene removal system DAS, all equipment SCS, MCS, ESD);

The application of Shanghai Automation Instrumentation Co. Ltd. in the coking industry, DCS has accumulated experiences in Liaoning lighthouse thermoelectric two shengmeng coking waste heat power plant, Hunan Shi Xing Xing group coking Limited, Shanxi Lu'an Wuyang peak coking limited liability company and Shanxi Linfen wanxinda coking company, Yunnan Fuyuan Dexin group etc. in the enterprise successfully DCS SupMAX800 products used in the production process control system of our company.

Engineering example:

Accumulated experience in the coking industry, other applications include:

There are two Liaoning lighthouse thermoelectric shengmeng coking waste heat power plant

For Hunan Xing Xing Ashmore group Coking Co. Ltd.

For Shanxi Lu'an Wuyang peak Coking Co. Ltd.

Linfen wanxinda coking company of Shanxi.
