Process for producing acrolein |
| abstract |
A process for producing acrolein which comprises bringing a reaction gas resulting from a catalytic oxidation of propylene into contact in a cooling tower with a condensate which is being circulated through the cooling tower and a circulating part, thereby to cool and separate the reaction gas and discharge an effluent gas from the cooling tower, the condensate in a bottom part of the cooling tower having a temperature of from 35 to 50°C, the effluent gas discharged from the cooling tower having a temperature of from 35 to 55°C, the temperautre of the effluent gas being kept nearly equal to or higher than the temperature of the condensate in the bottom part of the cooling tower, and a process for producing acrolein which comprises bringing a reaction gas resulting from the catalytic oxidation of propylene into contact in a cooling tower with a condensate which is being circulated through the cooling tower and a circulating part, thereby to cool and separate the reaction gases, the period of the residence time of the condensate in the cooling tower and the circulating part being from 0.5 to 3 hours. |
