ALNAT ZONE is a system designed to create an atmosphere profile for continuous furnaces. From the perspective of gas manufacturers, it controls the flow of gas within the furnace body and supplies the necessary amount of reducing gas to the required areas, significantly contributing to cost improvement and quality stabilization.
-
ALNAT C creates the necessary atmosphere by decomposing methanol within the furnace without using conventional reforming gas and diluting it with N2. These processes allow for: - Reduction in the maintenance and management of the reforming furnace. - The ability to create various atmospheres equivalent to DX gas and RX gas by changing the mixing ratio.
