智能电动执行器在韩国化学厂提供流量控制
在韩国大山的一个新的石化地点安装了超过100多个多转弯和部分旋转的智能电动执行器。智商执行器将在产生乙烯，聚乙烯和丙烯的植物中提供流动控制。
The project is a joint one between Hyundai Oilbank and Lotte Chemical. It is found 50 miles southwest of the South Korean capital Seoul. The new facility will produce 750,000 tons of ethylene, 750,000 tonnes of polyethylene and 400,000 tons of propylene per year. These chemicals are widely used to make plastic and synthetic rubber which in turn make automotive parts and other industrial materials such as packaging and pipes. The actuators have been installed in the cracking units in the plant to control the flow of the oil that is the feedstock at the heart of the production process. They operate ball, gate, globe and butterfly valves.
韩国内其他类似的旋转式项目给客户留下了深刻的印象，他们拥有的现有工厂中有500多个A-range和智商执行器。这些项目的操作和本地服务能力的稳定性导致他们为这个关键的石化地点选择旋转。客户还强调，选择这些执行器会导致电缆，安装和调试成本降低。
The Rotork Master Station provides a local centre for monitoring and controlling flow control assets. It is a control interface for Pakscan network loops, capable of operating up to 240 actuators across three separate field networks. The actuators will be linked by Rotork’s leading Pakscan™ network bus system and connected via a Rotork Master Station installed in the control room, operating two independent loops.
