Wataru Inomata
Department of Supply control and Disaster management, Tokyo Gas Co., Ltd.

  The Great East Japan Earthquake did not damage any important facilities used by Tokyo Gas for city gas production and supply operations, but some low pressure pipelines with low earthquake resistance were damaged, forcing the company to suspend supplies of gas to about 30,000 homes to preserve safety. This paper briefly describes initiatives taken by Tokyo Gas to provide prevention from earthquakes and its response to the Great East Japan Earthquake, which is centered on the super-dense real time monitoring earthquake system, SUPREME.

  At our Ashikaga mill, we have decided to utilize mobile DCS in order to update exist. Since mobile PC was still profound feeling, target was to be portable for operate. Hence, we try to implement tablet PC which has been spreading through the market.
  The tablet is not only for DCS, but also can help operator for work procedure, manual operate. We could build different mobile system from previous one by installed function can manage local process record as well.
  This report describes the outline of mobile system and operation.


Cyber-Security Controls for Industrial Control Systems

Kentaro, Hayashi
Service Division, Yokogawa Solution Service Corporation

  The introduction of Information Technology (IT) has improved performance, has reduced costs, and has added other important capabilities in industrial control systems. Since this technology has brought malicious attackers from the Internet world to industrial automation world, cyber-security risks such as computer virus infection have increased. Industrial control systems are generally utilized in mission critical infrastructure, so cyber-security is one of the most important concerns.
  In this paper, we firstly investigate the root cause of cyber-security risks prior to establish security controls. When introducing security controls, industrial control system users are supposed to build security policies. We show the key points to be considered for the policies. We lastly explore the best cyber-security solution to protect industrial control systems from attacks based upon security policies.
  Yokogawa have established Security Competence Laboratory in SingaporeCIndia, America and Japan. The main mission of Security Competence Laboratory is to research cyber- security technologies and to apply them to industrial control systems with our rich experience in industrial automation. Yokogawa have sufficient capabilities to protect industrial control systems from sophisticated attacks.

Junji Hoshi
Yatsushiro Mill, Nippon Paper Industries Co.,Ltd.

  Instrumentation technology is one of the key technologies of pulp and paper industries and other process industries. And it has contributed significantly to the improved productivity of the plant in the efficiency of production lines and labor saving represented by automation.
  On the other hand, personal high-performance computer was released in the late 1980s. Since then, continued to grow super-accelerated rate, and synergistic with the network technology such as the Internet, it became the basis technology to penetrate deeply well as any industry, even our lives.
  In recent years, instrumentation technology has evolved dramatically further by utilizing actively this IT technology, it has great potential depending on the idea.
  In this paper, as one of the initiatives aimed at the integration of IT and instrumentation technology, we introduce the application that using it to build and process data warehouse with integrated measurement and control real-time data of the plant. And mention about the future prospects for enhancing the application of measurement and control technology to the future.


The First Introduction Example of New QCS with Non-Contacting Optical Caliper Sensor

Takeshi Hashida and Takashi Endo
Fuji Mill, KJ Specialty Paper Co., Ltd.

  Recently, QCS (Quality Control System) is becoming one of most important component for Quality Management of papermaking. The result of developing various Quality Sensors and establishing Control strategies, Paper Industry tried to adopt an advanced stage of Production Management with QCS instead of the experimental rules.
  However, our industry got big impact through the financial crisis such as the Lehman shock in 2008. So, we started to consider not only for Initial investment but also long term maintenance cost to make a plan to replace or apply new equipment to our mill facilities. Under this kind of our environments, we decided to apply NDC ProNet QCS with Optical Caliper Sensor as 1st trial of thickness measurement for paper machine at Aug 2012. We would like to describe our experiences and evaluation using Optimike as completely non-contacting optical caliper on this paper.


Introduction of Fiber Weight Meter at Kasugai Mill

Sumio Hayakawa
Kasugai Mill, Oji Paper Co.,Ltd.

  Oji Kasugai mill has carried out replacements of QCS with the deterioration of electronic components. At the time of consideration of renewing QCS for 100% pulp tissue manufactur- ing process, sensor suppliers recommended the newly developed fiber basis weight sensor using infrared technology (gfiber basis weight sensorh). The characteristics of the fiber basis weight sensor are as follows.
  ① Both basis weight and moisture can be measured by one sensor, and that lead to a cost
  reduction.
  ② No official permission for containment of radioactive material, radiation protection
  supervisor or education and training for handling radioactive material are necessary.
  ③ Measurement data are influenced by the ash content in the web.
  For tissue manufacturing processes which do not contain the loading material, installation of the fiber basis weight sensor is reasonable for many advantages. Oji Kasugai mill therefore has started the introduction of the fiber basis weight sensor into tissue machines since Jan. 2010. As it was the first case of introducing the fiber basis weight sensor to tissue machines in Japan, the formal basis weight sensor using radiation was also installed as a benchmark until the measurement data of the fiber basis weight sensor become reliable.
  This paper describes three examples of the installation of the fiber basis weight sensor of two different manufacturers.


Case of Non-Contact Caliper Sensor Installation to Wrapping Paper

Tetsuo Funaba
Takaoka Mill, Chuetsu Pulp & Paper Co.,Ltd.

  In the recent years, QCS quality control system has become vital component in the paper production.
  6 QCS systems have been installed in Chuetsu Pulp & Paper Takaoka Mill.
  As for existing QCS system of No.1 machine, which was installed over 18years ago, and some of the controller parts has passed its maintenance warranty period which makes it difficult for the supplier to supply the parts. Hence, update of the QCS system was brought forward.
  Problems with the existing QCS system were that, the upper and lower contact surface of the contact caliper would clamp the paper and leave scratch marks on the paper which would cause the sheet break. This was seen significantly when measuring thin paper such as basis weight 20g/m2.  Therefore, to resolve this problem a non-contact type caliper sensor has been selected for this QCS system update.
  This document explains the measuring of the laser caliper sensor post installation.

  Review of AOX Measurement

  Masayuki Watanabe, Hitoshi Takagi, Hiro Iwata, Miyuki Nakagawa, and Hitoshi Okada
  Japan Pulp and Paper Research Institute, lnc.

  AOX (Adsorbable Organic Halogen) is a useful index of total organic chlorine compounds, and is used internationally as an evaluation method for the paper industryfs effluent. In Japan, AOX discharges from bleached pulp mills had been reduced by changing bleaching processes to ECF (Elementary Chlorine Free) since the last half of 1990s. We confirmed that the Japanese mills have low AOX discharges when compared with other countries. However, the AOX measurement method of Japan was different from other countries. In Japan, AOX was measured by the domestic method based on EPA9020B. On the other hand, AOX was measured by the ISO method based on ISO9562, EPA1650 and SCAN9:89 in other countries.
  Therefore, we investigated the influence of the method on the value. As a result, we found out that AOX measured by the ISO method was higher 1.3 times than the domestic method. It was considered that this result was caused by high hydrophile and low molecular chlorinated organic compounds in the effluent. AOX discharges from the Japanese mills are low, even if we use the ISO method.
  We can get the correct value at the same level with the ISO method, using the improved method which changed the washing solution of the domestic method into acid from neutral. Considering the correct value and the convenience, we recommend the improved method.
