The invention provides a light gasoline etherification system and a light gasoline etherification technological method thereof. The light gasoline etherification system comprises a methanol raw material tank, a light gasoline raw material tank, a static mixer, a fixed bed reactor and a catalytic rectifying tower, wherein an upper section, a middle section and a lower section of the catalytic rectifying tower is respectively provided with a rectification section, a reaction section and a stripping section; a first gas phase material extraction pipe is arranged in a manner of leading out of themiddle part of the reaction section and is communicated with a feeding hole of the catalytic rectifying tower; a second gas phase material extraction pipe is arranged in a manner of leading out of themiddle part of the stripping section and is communicated with the middle part of the reaction section of the catalytic rectifying tower. In the light gasoline etherification technological method based on the system, gas phase material extraction ratios of the reaction section and the stripping section are both 30 to 60 percent. According to the technical scheme, conversion ratios of etherificatedcarbon 5 and etherificated carbon 6 are greatly improved, and the light gasoline etherification system and the light gasoline etherification technological method thereof also have the technical advantages of simple technological method, easiness for realization, simplification of separation processes and high etherification production efficiency; moreover, the production operation cost is greatlyreduced.
Description
technical field [0001] This patent application relates to a clean gasoline chemical production system, in particular to a light gasoline etherification system device. Background technique [0002] The development trend of clean gasoline is low sulfur, low aromatics, low olefins and higher octane number. Various countries have also proposed stricter restrictions on the sulfur content and olefin content in gasoline. The current light gasoline etherification process mainly includes fixed bed etherification process and catalytic distillation etherification process. The catalytic distillation etherification process is a production process in which pre-reaction and catalytic distillation are connected in series, but the conversion rate of etherification reaction is generally Low technical issues. [0003] Patent CN107022375A discloses a light gasoline etherification system and light gasoline etherification process. The system mainly consists of light gasoline raw material tank, ...
