Problems solved by technology

[0004] Bubble reaction technology, which has serious back-mixing, many side reactions, long residence time, high loss, low product yield, and SO in the tail gas 3 The high content and long production cycle seriously restrict the improvement of product quality and output, and also have great pressure on the environment
[0005] Membrane reaction technology, operating conditions are harsh, and the reaction tubes are easy to block, which is not suitable for the situation of associated acid slag in our plant. Due to the pressure of environmental protection and waste, it is difficult to popularize and apply in the sulfonation of petroleum-based raw materials

Embodiment Construction

[0019] The principle of the spray film reactor is that the raw oil is atomized by the upward nozzle 10 under a certain pressure to form oil vapor, and micron-sized droplets (oil vapor) are formed in the space inside the reaction tank 11, and the SO 3 The gas is fully exposed to the reaction. The residence time of the reaction is controlled by controlling the length of the reaction tank 11 and the installation height of the nozzle 10; the heat extraction and temperature rise of the system are realized through the inner coil of the reaction tank 11 to ensure the heat balance of the reaction system; through the reaction tank 11 To control the acid value of the target product——petroleum sulfonic acid by cascading and controlling the feeding ratio of materials, to achieve the purpose of controlling the depth of reaction, to reduce the occurrence of side reactions, the yield of the target product has been improved, and the side reactions have been reduced. The loss rate has also be...

Abstract

The invention relates to an ejection atomize sulfonation reactor, used in mahogany sulfonate production. Wherein, it comprises ejector atomizer 6, ejector oil inlet 7, ejector 10, etc; the bottom of reaction pot 11 has tail gas outlet 3; the ejector oil inlet 7 has ejector atomizer 6; the bottom of reaction pot 11 has slag discharger 9, the pot 11 contains heating coil tube 12 whose two ends are mounted with temperature increase and decrease medium outlet 5 and inlet 8, to shorten reaction time, reduce side effect, improve yield and reduce the SO3 content.

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....
