What category do catalyst production facilities generally belong to?
Thread Content
The materials involved are mainly inorganic salts, inorganic acids and bases, and molecular sieve powder； The main processes include slurry synthesis (at normal temperature and pressure), spray drying (at high temperature and normal pressure), drying in an electric resistance furnace (at high temperature and normal pressure), packaging, a vacuum system, exhaust gas dust removal, and alkali solution absorption ； The main utility services include process water, 220V two-phase alternating current, 30S steam, 2S steam, nitrogen, and air. There is a methanol oxidation to formaldehyde plant nearby; what safety distance is required between the two?
Based on the aforementioned materials and processes, the fire hazard classification of this catalyst unit is Class V. The fire hazard associated with the oxidation of methanol to formaldehyde is classified as Class A; the fire separation distance between these two installations can be determined in accordance with Article 3.4.1 of GB50016, by referring to the fire resistance rating of the respective installations.
