DCS, SIS, PRM, FOUNDATION fieldbus instruments and OTS Installed at Thailand’s First LNG Terminal

Case Study by Yokogawa: Natural gas is Thailand’s primary fuel source and is absolutely essential to the country’s industries, particularly the power sector: two third’s of the country’s electricity is generated at gas-fired power plants. Much of Thailand’s natural gas comes from gas fields in the Gulf of Thailand. It is transported throughout the country via a network of offshore and onshore pipelines built by the national gas and oil company, PTT Public Company Limited (PTT PCL). In 2005, due to economic growth and the resulting shortfall in the supply of natural gas, the country’s National Energy Policy Board resolved to begin importing LNG.

In anticipation of this policy shift, PTT PCL established PTT LNG Company Limited (PTTLNG) in 2004 and tasked it with building and operating the country’s first LNG import terminal at Map Ta Phut, a deepwater port 220 km southeast of Bangkok. They send out gas to the adjacent Map Ta Phut industrial estate, which is one of Thailand’s most important industrial areas and home to a number of petrochemical, oil refining, steel, and fertilizer plants. Gas also be transported via the PTT pipeline system to power companies and other important industrial customers throughout the country.

ISA new publication explains the concepts, techniques and tools of advanced control

The International Society of Automation (ISA) announces that it has produced a new book that explains the concepts and terminology of advanced control, and highlights the advanced control tools and techniques most widely and effectively applied in the process industry today.

Advanced Control Foundation: Tools, Techniques, and Applications by Terrence L. “Terry” Blevins, Willy K. Wojsznis and Mark Nixon is designed to help control engineers and process engineers gain a more thorough understanding of the concepts and capabilities of advanced control products and solutions, which have been proven to reduce variation in plant operation, achieve production targets and improve plant production.

“The book is ideally suited to process and control engineers who have a sound understanding of conventional control techniques but have little or no background on advanced control,” says Blevins, who was instrumental in establishing Emerson Process Management’s Advanced Control Program and, along with his co-authors, has extensive experience in the design and startup of advanced control solutions. “It provides practical examples that allow readers to quickly become familiar with the advanced control techniques commonly utilized in the process industry today. In addition, the web site that accompanies the book (www.advancedcontrolfoundation.com) presents workshops on commercially available solutions that apply the advanced control concepts and techniques outlined in the book.”

Case Study: Yokogawa CENTUM System Automates Production Processes at Thai Renewable Energy Plant

Case Study by Yokogawa:  Established in 2006, Sapthip Co., Ltd., a subsidiary of Sapsathaporn Co., Ltd., produces ethanol for blending with gasoline. This gasoline blend, known as gasohol, is considered a renewable energy source because the ethanol is produced from cassava, a plant that is also grown as a staple agricultural product.

With its production of this renewable fuel, Sapthip is supporting the Thai government’s policy of reducing the country’s dependence on imported fuel. The company has been licensed by Thailand’s Ministry of Energy, Committee on Renewable Energy and Energy Conservation to produce fuel-grade ethanol (99.5%).

Waste to Energy Facility in UK controlled by CENTUM CS 3000 and ProSafe-RS

As existing fossil fuel reserves have become unviable or unreliable, the challenge of providing a secure energy supply for power generation within the UK has increased significantly in terms of both financial and environmental cost. At the same time, landfills lack the capacity to handle the increasing amount of household and municipal waste. While efforts to reduce, re-use, or recycle waste have made some headway, other options have had to be explored. One such effort underway that is making a valuable contribution toward providing a balanced and secure energy portfolio for the UK involves the extraction of energy from residual (non-recyclable) waste.

Lakeside EFW Ltd. operates an EFW (energy from waste) facility near London that is staffed by experts in energy recovery technologies who are working hard to ensure the plant remains efficient, technologically up to date, and above all, safe. The plant has the capacity to consume 410,000 tons of household and municipal waste per year and exports at least 34 MW per hour to the country’s National Grid. This process diverts the majority (over 97%) of waste from landfill.

Case Study: Remote and Centralized Monitoring System for Waste Water Treatment

Case Study by Advantech: Today’s society continues to face severe water pollution and scarcity problems. Even emerging countries generate more than a billion tons of wastewater every year and the amount is expected to grow due to rapid urbanization and industrialization. Fortunately, many governments have stepped up their efforts to improve the regulatory framework for modern wastewater management and with the assistance of Advantech’s solutions Waste Water Treatment Plants they can leverage their existing networks, hardware, and software. By introducing remote control and fiber optic communication as well as integrating management systems and reducing management costs, they can bring water treatment plants into the 21st century.

Wastewater is composed of water and some dissolved or suspended solid matter, and therefore needs to undergo a multi-stage treatment process to clean it before it’s discharged or reused. The process involves numerous phases, including: screening, pumping, aerating, sludge and scum removal, the killing of bacteria and the removal of waste water residuals. In response to such a complex procedure, the wastewater treatment plant often covers a very large area and has several buildings in which to install various for sewage sludge treatment facilities. Sometimes, these can be many kilometers apart: causing difficulties with continuously monitoring the equipment’s status. Meanwhile, a wide variety and a large amount of equipment with poor interoperability also caused maintenance problems. Because of these issues, the plant planned to upgrade its system using fiber optic communication and a remote monitoring solution to enhance the level of system automation.
