Continuous Hydrogen Analyzer

Built under a patented UOP design, the COSA/Xentaur Continuous Hydrogen Analyzer (CHA) provides petroleum refiners, petrochemical producers, and electric power generators a means to continuously and accurately monitor hydrogen concentration in gaseous streams. With its unique electrochemical sensor, the CHA outputs a continuous signal corresponding directly to the hydrogen concentration. Used in conjunction with real-time controls, alarms, and shut-off mechanisms, this instrument responds immediately to changing hydrogen levels for improved operations and safety.

Continuous Hydrogen Analyzer

Hydrogen concentrations are critical in many different refining, petrochemical, and electric power generation applications whether being monitored as a reactant, product, process "health" indicator, or coolant. COSA / Xentaur configure the Continuous Hydrogen Analyzer to match each installation's unique sample conditioning and operational needs.

CATALYTIC REFORMING
Catalytic reforming - By enabling on-line control of the hydrogen / hydrocarbon ratio, the Continuous Hydrogen Analyzer allows optimization of catalyst life and minimizes utility consumption.

ISOMERIZATION
Isomerization - Determining the hydrogen concentration is valuable at several different points in the isomerization process. Examples include: optimizing the hydrogen / hydrocarbon ration to assure stoichiometric balance; determining purity of recycled gas to reduce compressor utilities; monitoring makeup hydrogen purity; and detecting hydrogen - consuming side reactions caused by feed impurities, e.g. benzene saturation, which reduces the hydrogen in the offgas.

POLYOLEFIN PRODUCTION
Polyolefin Production - The concentration of hydrogen in the reactor dictates the molecular weight, and thus the physical and chemical properties, of the polymer. Continuous measurement of the hydrogen concentration allows for rapid changes from one polymer grade to another with minimal off-spec material.

HYDROGEN PRODUCTION
Hydrogen Production - By continuously monitoring hydrogen purity, the Continuous Hydrogen Analyzer immediately detects process upsets, bed poisoning, or processing deviations that lead to decreased yield and / or low product purity.

HYDROGEN - COOLED POWER GENERATION
Efficient and safe operation of hydrogen-cooled generators depends upon high hydrogen purity within the generator casing. The Continuous Hydrogen Analyzer enables power generation facilities to immediately detect casing air leaks which, if not corrected, can lead to windage losses and unsafe hydrogen - air mixtures.

HYDROTREATING
Hydrotreating - Continuously monitoring the hydrogen concentration of the gas stream to the reactor enable the operator to satisfy the chemical demands and control the coke rate, without causing excessive utility usage.
