SOPRECO® – Single Oven Pressure Control

SOPRECO® – Single Oven Pressure Control

High gas emissions generated during the first phases of coke distillation as well as air suction through oven doors at the end of distillation time are always a crucial concern for coke oven battery operators.

Driven by this environmental challenge, Paul Wurth developed SOPRECO®

(Single Oven PREssure COntrol), a system able to control the pressure independently in each oven of the coke battery.

Thanks to the innovative SOPRECO system, the pressure in the collecting main can be maintained below zero, optimizing the suction effect during the first phase of the cok-ing process.

Pressure regulation with SOPRECO guarentees a positive pressure at the base of the oven, even at the end of the carbonisation phase, thus avoiding air suction into the ovens.

Description

The valve is actuated in a continuous way by a hydraulic, pneumatic or electrical sys-tem, controlled by a PLC in function of the relevant oven pressure detected at the base of the ascension pipe.

The system includes for each ascension pipe: ` a special shape regulating valve ` a hydraulic/pneumatic/electrical actuator ` a pressure sensor ` a valve position sensor ` an insulating valve

Hardware and software for operating all ascension pipes complete the scope.

Main advantages

Retrofitted SOPRECO valves during testing at ZKS GmbH, Germany

` up to 90% reduction of emissions (doors, lids, stand pipes)

` minimization of stack emission by reduction of leakage between oven and heating wall (due to reduced pressure difference between oven and heating walls)

` simple mechanical device y easy installation y easy operation y robust design for a long life time y low maintenance y easy adaptation to existing

batteries for retrofit
