A typical alkylation unit. Output of high-value alkylate depends on close monitoring of hydrofluoric acid (HF) and water levels,
The system dramatically lowers personnel exposure as well as costs and delays in online monitoring of hydrofluoric acid (HF) by replacing two conventional methodologies for HF monitoring, manual sampling and costly Fourier Transform Near Infrared (FTNIR) analysis.
ACA.HF provides real time monitoring of HF, and water concentrations within an alkylation process, helping to maximize yield rates of the unit. Traditional approaches to HF monitoring involves taking manual samples and analyzing them in a laboratory, but this sampling offers limited accuracy and exposes lab workers to toxins. More recent FTNIR techniques are highly accurate, but adaptation for real-time online monitoring is complex and costly due to the acquisition and installation as well as maintenance-heavy nature of the method.
在ACA.HF的开发中，Invensys Operations Management与领先的炼油厂合作，创建和验证新的在线HF监控模型，这些模型可在收购和运营成本明显降低时提供高度可靠的结果。
The new ACA.HF Advanced Measurement system costs about half that of an FTNIR system and requires minimal maintenance, because its core components are built from rugged materials long proven in industrial HF applications. Based on established industry methods, estimated mean time between failures (MBTF) of the solution exceeds 29 years. There were, in fact, no maintenance costs in the first year of implementation at the development partner's refinery..
监视模型在新的Foxboro PAC系统控制器中运行，该控制器提供了一种经济高效且易于设置的应用程序环境。先进的分析软件在本质上可以通过创建与传统FTNIR产生的虚拟频谱的精确控制。
"The solution brings together proven corrosion-resistant sensor technologies, advanced mathematics and software development, and existing ECS components and data flow," Dickson said. "Collaboration with our customer brought us expertise in the alkylation process in general and HF needs in particular. Bottom line, we had all the resources needed to build a reliable, repeatable system to translate density, conductivity and pressure data into real-time HF monitoring."
This unique measurement and control solution contributes to asset excellence by minimizing the potential for corrosion. At the same time, it supports environmental and safety excellence by eliminating the need to bring operations and laboratory personnel into close contact with HF, a common concern in manual sampling.
还消除了涉及权限和时间的延迟，以获取烷基化单元，以及与手动方法相关的培训和安全服装成本。其他好处包括新见解何时激活饲料干，从长远来看，这可以节省大量能源。
The ACA.HF solution is an integral component of the company's InFusion Enterprise Control System, as it shares a common communications and applications development environment that enables the solution to be part of a larger plant and enterprise control, information and decision support system.
“真正的- - - - - -time results provides operations new ways to predict alkylate production accurately," said Brian Dickson, Vice President and General Manager, Field Devices, Invensys Operations Management. "This means that operations gain insight into which orders to pursue and where to spend money—and perhaps most importantly, offer reliable output numbers that corporate can use to increase sales activity."
迪克森说：“该解决方案的最大拥护者是尝试过的人。”“ ACA.HF与一支致力于快速，安全的安装和调试的团队有帮助。”
