 How is methyl ethyl ketone produced? The production of methyl ethyl ketone comprises passing a feed consisting of secondary butyl alcohol in its vapor form over a fixed bed of an improved copper silica catalyst prepared by sol-gel method at LHSV in the range of 1 to 20 per hour at a temperature in the range of 210°-350° C. Mainly by the following steps: Step 1: Butene concentration process. Step 2: SBA Hydration Process. Step 3: SBA refining process. Step 4: MEK synthesis and purification process. Step 5: Process water regeneration process. In the methyl ethyl ketone processing, our large stainless steel wedge wire water distributor/lateral distributor and filter nozzles play a very important role. The specification and size of the lateral distributor used in MEK processing can be custom according to the actual requirement. Welcome to contact us at any time!
