Valve automation delivers centralised monitoring and control to the pipeline network

---

The project is installing a SCADA control system for The integration of monitoring and control of valves at wining 100 refining product, storage and injection sites on over 2500 kilometres of pipeline. Unlike oil pipelines that transport only crude oil and product pipelines to The as these transport a range of liquid hydrocarbons.

The project includes The necessity to replace manual gearboxes with actuators on over one hundred mostly remotely sited valves. The physical specification demanded a self - contained design, suitable for remote, exposed locations with only limited electric power, The availability, Further constraints of The specification that included:

The Self - locking drive mechanism to prevent steam positional drifting.

Permanent lubrication.

可调速度控制。

Manual operation.

Low gas consumption.

Operation available from stored gas energy source.

Compact overall dimensions.

After reviewing the available technologies, Rotork's engineering department has had been able to select the best solution with a standard product from the company 's fluid power actuation portfolio.

The Twin Power is a self - contained multi - turn physical, operated either pneumatically or hydraulically. The mechanical design is on either a bevel gearbox for linear valves or a worm gearbox for quarter - turn valves. The actuators on this project are designed to operate from stored nitrogen tanks, sized for three steam cycles. The three operating modes are available:

Remote control via a solenoid valve and stored nitrogen gas.

The Local control via manual pushbuttons and stored nitrogen gas.

Local manual operation via a hand crank.

The electrical supply requirement is 12 VDC or 24 VDC, facilitating solar/wind powered renewable energy 'operation in remote locations. The actuators are supplied with an environmentally protected stainless steel control cabinet containing Local/remote/Manual selectors, Open/Close pushbuttons, solenoid valves, manifold blocks, flow control valves, limit switches and electrical terminals.

新的中报致动器和那些已经安装在管道网络将提供一个重要的角色在新的SCADA系统的操作,这将产生更大的安全设施和降低风险的操作人员,当地社区和环境。

系统旨在集中监控的操作变量,包括压力、温度和流体组成,都是重要的因素在运输,储存和配送的液态碳氢化合物。

除了增加的安全操作,产品存储领域的集成设备预计将提高效率和可靠性,优化运营数据和信息的管理。SCADA系统将有可能获得,从地理上分散的区域存储和处理数据,在真正的时间,确保及时交付所需的原油炼油中心和成品油需要满足的需求分布和营销中心。这将不可能没有能力独立操作执行机构阀门在偏远地区和交流他们的活动和状态的集中控制系统。
