What are Gas Analyzers?
Real-time gas analysis enhances efficiency, safety, throughput, product quality, and ensures environmental compliance. Gas analysis can utilize various technologies such as tunable diode laser spectroscopy, zirconia oxygen analysis, infrared gas analysis, stack gas analysis, dust monitoring, process gas chromatography, continuous emissions monitoring systems (CEMS), hydrogen purity analysis, and gas density systems. Selecting the correct technology is critical to measurement accuracy, reliability, and durability.
Yokogawa's years of application expertise enable our customers to save time, money, and resources by collaboratively selecting the optimal gas analyzer solution.

The U.S. refineries represent approximately 23 percent of the world's petroleum production, and the United States has the largest refining capacity in the world. Petroleum refining is an industry, which is undergoing intense amounts of scrutiny in the United States from regulatory agencies and environmental groups.
Environmental pollution caused by volatile organic compounds (VOCs) has become a global environment issue, including issues on effects upon health. This paper introduces a system based on detection and sampling technologies and developed for measuring goes in the global environment. Small amounts of VOCs are measured with a gas chromatograph or photoionization detector (PID). VOCs in water are sampled using a sparging method. A small quantity of VOC constituents of more than 20 different types can be measured with a gas chromatograph using a programmed temperature oven. The PID can detect a ppb level of VOCs that are ionized using a vacuum ultraviolet radiation lamp. We expect these devices will be useful for improving the global Environment.
Marcus Trygstad, Yokogawa Corporation of America, outlines the advantages of EUVF technology for total reduced sulfur measurement in flare gas.
The EPA rule, 40 CFR 63 Subparts CC and UUU, is forcing refineries to monitor flares. Fortunately, modern analyzer technology makes it possible to meet the requirements, generate the necessary reports, and stay in compliance.
Here’s how to select the right analyzer to meet these demands.
Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning. The non-contacting sensor allows for a variety of process types including corrosive, abrasive and condensing. The first generation platform has been proven in many others for the measurements of O2, CO, CH4, NH3, H2O and many more NIR absorbing gases. This second generation platform has improved reliability and ease of installation and maintenance while still meeting or exceeding designed application demands.
