Una terminal (o un gran depósito) es un área de almacenamiento donde los productos de petróleo y/o químicos se reciben a través de tuberías de fondo y/o embarcaciones marítimas y se almacenan en un patio de tanques. Estos productos son redistribuidos por camión, gabarra, vagón cisterna (o carro), y medios similares. Yokogawa ha acumulado más de dos décadas de experiencia en la automatización de este tipo de terminales y ha lanzado una solución empaquetada, Terminal Logística Suite de VP.
Manual operations at a terminal, such as manual loading/unloading and manual recording of bills of lading and bills of materials, are not only time consuming, but also can lead to injuries and unavoidable costs caused by human errors. Therefore, terminals with limited process automation solutions lack safety and efficiency, and might not be able to deliver products on schedule or that meet the minimum required specifications.
Yokogawa's terminal automation solution, Terminal Logistic Suite VP, consists of level 3 solutions (production/MES layer) and level 2 solutions (control system layer). It satisfies the requirements of terminal customers in the oil, gas, LNG, LPG, chemicals and petrochemicals industries, without requiring a lot of customization work.
The control system in this solution handles the loading and unloading of products at the terminal. Its functionality comprises all necessary monitoring and control functions for excellent terminal operation. Definitions of control properties can be downloaded from the MES into the controller for execution. The controller then executes the movement control function with ease and efficiency, and monitors the quantities transferred to ensure accurate control, while issuing alarms as necessary in response to inadvertent operations or equipment malfunctions.
Control platforms can be selected to match the diverse needs of users. For example, a relatively small terminal for truck loading would use PLC (FA-M3), while a larger terminal would use either RTU (STARDOM) or DCS (CENTUM VP).
Examples of functions that can be automated by the solution at a terminal:
To maximize overall operational efficiency at terminals, a good terminal control system to improve the loading speed is indispensable. However, it is also necessary to integrate the terminal control system with the terminal's Manufacturing Execution System (MES) to guarantee the seamless and smooth flow of information throughout the terminal to achieve overall operational excellence.
Terminal Logistic Suite VP is Yokogawa's true level 3 (production/MES layer) terminal automation solution. It has direct links to the upper ERP layer and to the lower control system, in addition to a collection of separate modules for materials transfer, path generation, jetty/bay scheduling, production scheduling and other logistic operations. It addresses challenges for faster and more efficient delivery of products. It also provides flexibility for changes, improves safety, reduces administrative work, enhances the visualization of operations and improves traffic management, thus allowing operators to make accurate decisions.
Safety is the first concern and top priority for terminal stakeholders, because it is the most critical element to ensure operational availability and profitability of the terminal in the long run.
ProSafe-RS is Yokogawa's IEC61508 and ANSI/ISA 84 compliant safety system. Including terminals, it has been used in more than 1,500 projects, ranging from large-scale integrated process automation projects to stand-alone systems for small projects. By monitoring the safety loops consisting of field sensors, safety valves and final control elements, Yokogawa's Prosafe-RS solution can help customers achieve true safety at their terminal.
Yokogawa's Advanced Operating Graphics (AOG) solution is an enhanced redesign of the Process Control Station (PCS) graphics based on human factors engineering and knowledge engineering. AOG provides intuitive situational awareness through ergonomic design, such as color selection and layouts based on operating procedure and environment.
Yokogawa has gained years of experience in automating terminals/depots and can provide concept-to-commissioning solution, based on proven technologies and its accumulated know-how for all your terminals.
Yokogawa's Terminal Logistic Suite addresses challenges such as shortening the product delivery time, improving loading efficiency, adapting to changes in the manufacturing process, improving safety, increasing administrative efficiency, reducing labor costs, integrating data systems, visualizing operations and managing traffics, etc.
Universal Terminal (S) Pte Ltd, one of the largest independent petroleum products storage terminals in the Asia Pacific, has been built on Singapore's Jurong Island at a cost of S$750 million.
A medida que aumenta la demanda mundial de alimentos, los fertilizantes juegan un papel esencial en la mejora de la productividad agrícola. El Nitrógeno OCI (en adelante OCI) es un productor líder de fertilizantes minerales y el mayor productor mundial de melanina, los cuales se utilizan para hacer adhesivos y resinas para una amplia gama de aplicaciones, tales como paneles de muebles, pisos laminados, revestimientos, pinturas y plásticos.
Martin te Lintelo, Yokogawa Europe B.V., The Netherlands, discusses high level control system design for LNG receiving terminals. As demand for LNG increases worldwide, players face seemingly conflicting challenges. On one hand, they must expand capacity in different regions, make the business and production as agile and adaptive as possible, and improve operational efficiency.
The LNG sector presents challenges for the automation supplier, particularly in the implementation of automation systems for regasification terminals. Yokogawa Europe's business development manager, upstream oil and gas Martin te Lintelo looks at the handling of the potential automation-related problem areas and opportunities.
