Low-Carbon Society and Environmental Improvement

Author: Masayuki ADACHI; President & COO, HORIBA, Ltd. -HORIBA Group is emerging as a vital player in the energy management field from present fossil-fuel combustion to next-gen various source conversion, to electricity. Not just in the environmental and energy field, our mission will be to correspond quickly, and remain flexible when following changes in the global market. Focusing on miniaturization and verticalization in the semiconductor manufacturing process, AI technology introduction in the automotive, medical, and various industrial processes, or IoT (Internet of Things) expansion will directly impact the HORIBA Group enterprise. I shall review every HORIBA Group potential from higher viewpoint and charge into the next stage.

Author: Satoshi INOUE; HORIBA, Ltd. -In recent years, we are facing a turning point in energy supply. Historically, the energy-supply structure of the world has been based on fossil fuel from the Middle East and South America. Consumption of alternative energy is expanding to mass consumption regions and is dramatically changing the utilization profile. This report addresses the current situation and issues of the energy-supply structure. HORIBA’s measurement technologies are introduced for the energy-producing suppliers.

Author: Xiaoyang YANG, Shijie LIU; Atmospheric Environment Institute, Chinese Research Academy of Environmental Sciences, China -Chemical elements are major components of PM2.5 and crucial tracers to identify the source of aerosol particles using source apportionment models such as Positive Matrix Factorization (PMF) model and Chemical Mass Balance (CMB) model. In this study, PM2.5 samples were collected hourly from November 28, 2016, to May 30, 2017 in a chosen location within Beijing. Mass concentration and elemental composition were detected using an X-ray fluorescence-based online elemental analyzer (PX-375, Horiba, Kyoto, Japan).Based on the PMF source analysis, the primary sources of PM2.5 during the observation period in Beijing, in descending order of contribution to PM2.5, were secondary particles (44.0%), coal burning (28.3%), vehicle emission (17.2%), dust (7.9%), and fireworks (2.5%).

Author: Erika MATSUMOTO; HORIBA, Ltd. -Particulate matter (PM) is one of the major contributors to air pollution. There is a need for simultaneous measurement of PM and its chemical properties to adjust processes parameters quickly and identify emission sources. The PX-375 simultaneously measures the mass concentration and elemental composition. The PX-375 relies on the beta ray attenuation and x-ray fluorescence techniques. A comparison with the manual analysis technique (ICP-MS) shows good correlation with field data collected.

Author(*) Information: HORIBA, Ltd. In recent years, laser gas analyzers have been introduced into various plants such as incineration plants and petrochemical plants. Since laser gas analyzers do not require the troublesome process of gas-sampling at the time of measurement, laser gas analysis provides fast response time which enables the plants to operate with high efficiency. The cross-stack laser gas analyzer is already widely used, there are several issues surrounding this device. Not only does the cross-stack analyzer have a restricted place for installation, but it also requires complicated operations to remove the analyzer from the stack for calibrated. As a response to these circumstances, HORIBA has succeeded in creating the TX-100, which is the first direct-insertion laser hydrogen chloride analyzer in Japan*1 to use a probe type optical system to overcome the prior issues. This paper will feature the principles, aspects, and examples of measurements at incineration plants. *1: In-company investigation in August 2018

Author: Hiroshi KANDA*, Hirotaka EGUCHI, Hisato TAKIGUCHI, Hideaki TANAKA, Kazuhiro IRIE ; HORIBA Advanced Techno, Co., Ltd. -"HAKARU EXpress" is a solution-based business aimed at streamlining water quality management, offering to solve the problems that Japan as a society is currently facing, including the issues of how to pass on technical know-how to other workers, as well as reducing manpower required for management in order to make operations more efficient. HAKARU EXpress differs from conventional business models in that it offers the value inherent in the water quality “values” measured by these instruments. This system is used to remotely monitor the condition of water quality measuring devices to optimize inspections and rapidly respond in the case of a malfunction as the manufacturer performs all tasks from data analysis to preventive maintenance. In this paper, we describe the results of using HAKARU EXpress with our Automatic Total Nitrogen/Phosphorus Monitoring System, a water quality measuring device used in the field of factory wastewater management, as our first line of business, and explain the objectives and future prospects of this system.

Author: Kazunori MIZUMOTO*; HORIBA, Ltd. -The VA-5000 series is a series of Multi-Component Gas Analyzers that can measure up to four components with one unit. Measurement principles of NDIR (non-dispersive infrared method), CLA (chemiluminescence analysis), and Oxygen analysis method (MPA (magnetopneumatic method), zirconia method, and galvanic cell method) can be utilized. This product has been developed as a successor to the Multi-Component Gas Analyzer VA-3000 series. It has been improved in such aspects as miniaturization of the device size, increasing the maximum number of components that can be measured (maximum: 4 components), high sensitivity (minimum concentration range: 50 ppm), operability. This article describes the features of the VA-5000 series and introduces examples of application to the IGCC (Integrated coal Gasification Combined Cycle).

Author: Yu TAKIGUCHI*: HORIBA, Ltd. -IT-480 series is infrared radiation thermometer and developed for industrial need temperature control with high accuracy and high repeatability. IT-480 series can measure temperature non-contactly and nondestructively by measuring infrared rays from measurement target, different from conventional contact thermometer. High accuracy and high repeatability were realized by thermopile sensor using MEMS technology of silicon semiconductor process, optical interference filter eliminating influence of atmosphere, and high precision blackbody furnace as calibration standard for temperature measurement. In this paper, we describe the measurement principle and features of radiation thermometer and introduce the high-precision infrared thermometer IT-480 series.

Author: Sofia GAIASCHI*, Patrick CHAPON, Akira FUJIMOTO, Tatsuhito NAKAMURAA; HORIBA FRANCE SAS -RF Glow discharge Optical Emission Spectrometry is a recognized analytical method for elemental depth profile analysis of surface and interfaces of solid layered materials. The possibility of easily pulsing the RF source has widened the application domains and enhanced the performances and for all recent applications, whether it is enhanced depth resolution, measurement of fragile materials, plasma cleaning or use of the GD source for SEM observation, pulsed operation is a key asset. In this paper we will illustrate the benefits of pulsed RF operation in Glow Discharge Optical Emission Spectrometry.
