Gas Component Trend Analysis and Management

Monitoring System for Unrefined Gas

JFE supplies an on-line continuous unrefined gas component analyzer with a low maintenance load!

Solution Point

Suppresses precipitation of solidified/aggregated components in the sample gas piping.
Supports trend analysis and management for multiple species of gases.
Realizes early analysis, enabling feed-forward to the downstream process, because the analyzer can be installed upstream of the gas treatment process.
Contributes to reducing risk of explosion in the refining process, as early grasping of oxygen concentration is realized because the analyzer can be installed upstream of the gas treatment process.
Contributes to reducing risk of explosion in the refining process, particularly because the oxygen concentration can be grasped at an early timing.
Low analyzer maintenance load

Features 01

Expected Problems

・Don't you have needs for monitoring of the components of gas (O₂, CO, H₂S, NH₃, etc.) in the refining process before refining is completed?

Features 02

Technology highlight

・Gas heating function to suppress precipitation of solidified/agglomerated components in unrefined gas in the sample gas piping.

・Special design that prevents drain from flowing around into the measuring instrument.

・Maintenance cycle is 1 time/year (example of coke oven gas in JFE Steel, but depends on the gas used and the environment).

Features 03

Proposed Solutions (Examples)

・Enables early detection of the risk of explosion in electrostatic dust precipitators by quick grasp of rises in the oxygen gas concentration in flammable gases.

・Enables optimum operation of the gas refining equipment because the concentration of the refined gas can be understood continuously in real time before refining.

・Makes it possible to omit the pretreatment (sample preparation) and glass tubes for gas analysis, which are necessary in analysis of unrefined gas by the conventional method, realizing labor-saving and safe work.
