An Enhanced Mass Transfer and Heat Transfer Reactor Applicable to Petroleum Sulfonate Production

Abstract

An enhanced mass transfer and heat transfer reactor suitable for the production of petroleum sulfonate, the invention belongs to the field of petroleum sulfonation reaction devices, including a tank body, an upper support ring and a lower support ring are fixedly installed in the tank, and the upper support ring and the The lower support ring is respectively provided with several rotating rings, the inner circumference of the upper support ring and the inner circumference of the lower support ring are respectively connected to the outer circumference of the corresponding outermost rotating ring through sealed bearings, and the bottom side of the lower support ring is fixedly connected to the circle. On the top side of the box, the lower end of the connecting pipe is connected with the inside of the round box. Air outlet, waste air hole, discharge port and slag discharge hole are opened on the tank body in sequence. The fixed installation on the tank body can drive the inner and outer adjacent rotating rings to reverse Rotary drive. Through the dislocation rotation of the connecting pipe, the atomized feedstock oil and sulfonating agent are fully stirred to increase the mixing effect of feedstock oil and sulfonating agent. The chemical reaction temperature is maintained at an appropriate temperature.

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
