Nederlandse Aardolie Maatschappij (NAM) is the Netherlands' largest natural gas producer. In addition to onshore fields, NAM operates manned platforms and four unmanned monotowers in 19 offshore locations. These connect to a pipeline network that comes ashore at Den Helder. 

STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.

Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.

One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.

The major methods of improved oil recovery are water flooding and steam injection. "These technologies make a tremendous contribution to recovering additional oil from old wells as well as improve primary recovery of operating oil fields."

La configuration du transmetteur de niveau peut prendre beaucoup de temps. Les calculs requis pour déterminer les valeurs de plage correctes pour les transmetteurs traditionnels peuvent devenir complexes en raison de la disposition physique d'une application.

HART communication is a means of transmitting multiple signals by superimposing long-standard 4-20 mA DC analog signals on digital signals. The figure below is an example of connecting field instruments and upstream devices using HART communication compatible VJA1/H signal conditioners.

The paperless recorder DX series instruments allow you to determine temperature and humidity, and manage the results as manufacturing and quality data at a reasonable cost with a simple configuration.

Yokogawa provides controller embedded flow calculation library based on AGA (American Gas Association) reports.

Reverse osmosis (RO) is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.

• Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
• During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
• Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.

Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.

Recently, several ARC Advisory Group analysts and management team members had a chance to sit down with the new Yokogawa President and COO, Mr. Takashi Nishijima, and several other top Yokogawa executives to discuss the company's burgeoning presence in the worldwide upstream and midstream oil & gas industry.

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.

Tuning PID controllers can seem a mystery. Parameters that provide effective control over a process one day fail to do so the next. The stability and responsiveness of a process seem to be at complete odds with each other. And controller equations include subtle differences that can baffle even the most experienced practitioners. 

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux.

From engineering to installation, commissioning, operations, and maintenance, FOUNDATION fieldbus offer significant cost reductions of 30 percent or more versus conventional analog systems. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.

Migration of a refinery's DCS provided an opportunity to reconfigure and consolidate the control rooms and operational management system.
