In situ gas analysis RS2200PAT Series

The Jianzhi® RS2200PAT/RS5200 online Raman analyzer is a dedicated gas-analysis instrument for direct industrial installation. Its fiber-optic probe tolerates 300℃ and 5MPa for direct high-temperature, high-pressure gas measurements. Applications include fine chemicals, fluorine chemicals, petrochemicals, coal chemicals and metallurgy, particularly real-time analysis of highly toxic or strongly corrosive gases.

Phosgene and phosgenation processes—phosgene, diphosgene and triphosgene. Chlor-alkali electrolysis—chlorine, hydrogen and nitrogen trichloride. Chlorination—chlorine and HCl. Fluorination—hydrogen fluoride. Ammonia synthesis—high temperature and pressure, hydrogen and ammonia. Nitration—toxic nitrogen-oxide byproducts. Hydrogenation—high-pressure hydrogen and hydrogenation off-gases. Oxidation—ethylene oxide and similar substances. Amination—ammonia. Diazotization—toxic gas byproducts. HCN production—ammonia, HCN and other toxic gases. Fluorine chemicals—HF, HCl, SiF, F₂ and SO₂. Petrochemicals—ethylene-cracker gases such as CH₄/C₂H₆/C₃H₈/C₂H₄/C₂H₂. Coal chemicals—gasifier-outlet H₂/CO/CO₂/CH₄/C₂-C₃ hydrocarbons and heating value. Operating-condition type: highly toxic gases. Representative applications: phosgene synthesis (COCl₂), HCN synthesis, fluorine preparation, hydrazine propellants and silane/phosphine/arsine. Operating-condition type: high temperature. Representative applications: ethylene cracking (>800℃), waste incineration and blast-furnace gas. Operating-condition type: high pressure. Representative applications: coal gasification, methanol synthesis, natural-gas purification and hydrogen refueling. Operating-condition type: severe corrosion. Representative applications: fluorine chemicals, ammonia synthesis, HC and HF. Operating-condition type: sulfur-containing media. Representative applications: sulfur recovery, natural-gas desulfurization and coal-to-liquids syngas. Application examples: in-situ multicomponent analysis of highly corrosive gases during production of anhydrous HF by the fluorosilicic-acid method; in-situ analysis of high-temperature, high-pressure off-gases from DNT hydrogenation in polyurethane TDI synthesis; multicomponent gas analysis during phosgene synthesis for precise control of highly toxic reactions; multicomponent gas analysis during HCN synthesis as a safety barrier for hazardous-chemical synthesis.

In-situ analysis without sampling avoids contact with hazardous samples. Withstands harsh conditions up to 300℃ and 5MPa. Broad applications, with detection of multiple gas components. Fast analysis: each measurement completes within 60s. Multipoint analysis: 1 main unit supports 8 channels for cyclic, continuous analysis at 8 points.
