Gas Analyzers

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.

NH₃ injection lowers NOx in stack flue gas, boosts dust collection efficiency, and prevents erosion. Precise measurement and control of NH₃ are crucial to avoid excess use, which increases costs and causes odors. The TDLS8000 solves these issues with direct measurement for effective NH₃ management.

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.

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.

Marcus Trygstad, Yokogawa Corporation of America, outlines the advantages of EUVF technology for total reduced sulfur measurement in flare gas.

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.
