Description

Technical field:

[0001] The invention belongs to the sulfonation reaction technology in the production process of petroleum sulfonate, i.e. SO 3 SO in mixed gas 3 Reaction with oil is a gas-vapor homogeneous reaction technology, specifically, a jet mist film sulfonation reactor. Background technique:

[0002] Currently used bubbling sulfonation reaction technology, the SO 3 The mixed gas is passed into the reactor below the liquid level of the liquid phase reactant, so that SO 3 The mixed gas reacts with the raw material in the form of bubbles in the sulfonated material. A cooling coil is installed inside the reactor to remove the heat of reaction. The non-ideal components (acid slag) produced by the reaction will settle from the bottom of the reactor Excluded, the target product petroleum sulfonic acid produced by the reaction overflows out of the reactor through the upper part of the reactor, and the tail gas after the reaction is discharged from the top of the reactor....
