Regarding the methanol oxidizer interlock issue
Thread Content
The process flow for the oxidation of methanol to formaldehyde (silver method) is roughly as follows: the four-component gas is evenly mixed in a mixer and then fed into an oxidizer equipped with a catalyst. The reaction gas passes through the catalyst layer from top to bottom, where methanol is oxidized and dehydrogenated under the action of the catalyst at 600–650°C to produce methane gas. May I ask whether the key control parameters for this process, such as the oxygen-alcohol ratio, temperature, and pressure, are currently under automatic interlocked control? And how is it controlled?
At present, the main control parameters of this process, such as the oxygen-alcohol ratio, temperature, and pressure, are under automatic interlocked control
