Application Note Power Bulk and Specialty Gas Purity Measurements Industrial gas bottling and blending plants require accurate gas concentration monitoring of bulk and specialty gas products to ensure purity requirements for a variety of end users. Emerson offers several Rosemount Analytical gas analyzer methodologies to meet the gas monitoring needs of gas bottling plants. Large scale production of important industrial bulk gases such as nitrogen (N ), oxygen (02) and argon (Ar) isperformed in an air separation plant. Other gases of commercial importance which are usually not obtained directly from the atmosphere include: hydrogen (H2), helium (He), carbon dioxide (C02), carbon monoxide (CO), ammonia (NH3), sulfur dioxide (S02) and other specialty gases. Bottling plants fill cylinders with various gas products and blends to meet the demand fora variety of end-use applications. Likewise, monitoring gas purity at both ends of the bulk gas supply network can be important. Point monitoring at the high-pressure cylinder filling manifolds and outlet lines of the airsepa ration plant or gas manufacturing facility as well as the custody transfer receipt at the bottling plants, may all require accurate and reliable gas Emerson provides a wide range of Rosemount Analytical analyzer methodologies to meet the monitoring needs of a gas bottling plant. Table 1 highlights several of these application solutions. The end-user applications all have product purity and concentration and blend accuracy requirements. These applications include: ■ Electronic and semi-conductor manufacturing ■ Inert process blanketing/purging ■ EPA protocol gases used as calibration standards for Continuous Emission Monitoring Systems (CEMS) and mobile source test vans ■ Engine emission testing standards ■ Safety and industrial hygiene ROSEMOUNT* EMERSON.
