Reinforced mass and heat transfer reactor suitable for petroleum sulfonate production

Abstract

The invention discloses a mass transfer and heat transfer enhanced reactor suitable for petroleum sulfonate production, and belongs to the field of petroleum sulfonation reaction devices. The reactor comprises a tank body, an upper support ring and a lower support ring are fixedly mounted in the tank body, and a plurality of rotating rings are arranged in the upper support ring and the lower support ring respectively; the inner circumference of the upper supporting ring and the inner circumference of the lower supporting ring are rotationally connected with the outer circumference of the corresponding outermost rotating ring through sealing bearings, and the bottom side of the lower supporting ring is fixedly connected with the top side of a round box; the lower end of a connecting pipe is communicated with the interior of the round box, and a gas outlet hole, a waste gas hole, a discharging opening and a slag discharging hole are sequentially formed in the tank body; and a driving device capable of driving the inner and outer adjacent rotating rings to rotate reversely is fixedly mounted on the tank body. Atomized raw oil and a sulfonating agent are fully stirred through staggered rotation of a connecting pipe, and the mixing effect of the raw oil and the sulfonating agent is improved; and meanwhile, the connecting pipe is cooled through cold air in the connecting pipe, and the reaction temperature of the raw oil and the sulfonating agent is kept to be proper.

Description

technical field [0001] The invention belongs to the field of petroleum sulfonation reaction devices, in particular to an enhanced mass transfer and heat transfer reactor suitable for the production of petroleum sulfonate. Background technique [0002] Petroleum sulfonate is a product made of petroleum and its fractions as raw materials, sulfonated with a sulfonating agent, and then neutralized with alkali. Petroleum components used as raw materials for sulfonation, although after a certain refining process, most of the colloidal asphaltenes and sulfur nitrogen oxides and other non-ideal components have been removed, but due to the complexity of the raw material components, sulfur trioxide and petroleum components sulfonate Acid slag is easily produced during the sulfonation process, which not only reduces the yield of sulfonate, but also causes serious pollution to the environment. In order to avoid excessive sulfonation, it is necessary to fully mix the raw material oil wit...

Petroleum components used as raw materials for sulfonation, although after a certain refining process, most of the colloidal asphaltenes and sulfur nitrogen oxides and other non-ideal components have been removed, but due to the complexity of the raw material components, sulfur trioxide and petroleum components sulfonate Acid slag is easily produced during the sulfonation process, which not only reduces the yield of sulfonate, but also causes serious pollution to the environment. In order to avoid excessive sulfonation, it is necessary to fully mix the raw material oil with the sulfonating agent and reduce the reaction temperature. Therefore, we design A reactor capable of enhancing mass and heat transfer
