Abstract
The invention discloses a sulfonation reaction cooling method in an acesulfame synthesis technology. The method is characterized in that liquid ammonia is adopted to replace copious cooling brine and enters a heat exchanger as a cooling agent to directly cool a sulfonation kettle, and the temperature in the sulfonation kettle is controlled by regulating the flow of the liquid ammonia so as to meet the temperature requirement of sulfonation reaction. The method has the advantages that based on the characteristics of low specific gravity and low boiling point of the liquid ammonia, heat generated in sulfonation reaction is taken away through sublimation of the liquid ammonia so as to achieve cooling. Compared with an existing cooling method, restrictions on production from brine pumps are eliminated, the usage quantity of brine pumps is reduced, and a large amount of electric energy is saved; the purchase and installation cost and the repair and maintenance cost of brine tanks and dry evaporative cooling equipment are lowered, annual calcium chloride consumption and soft water consumption are reduced, and influences on the environment in the overhaul process are eliminated.
Description
Technical field
The present invention relates to acesulfame potassium synthesis technique field, particularly sulfonation reaction method of cooling in a kind of acesulfame potassium synthesis technique.
Background technology
Sulfonation workshop section, as the main workshop section affecting acesulfame potassium yield, wants less than-30 DEG C to carry out just guaranteeing that reaction is carried out smoothly in this workshop section's reaction needed.Traditional acesulfame potassium production technique sulfonation workshop section as shown in Figure 1, temperature in the kettle is controlled with deep cooling salt solution (calcium chloride solution of more than 30%) cooling, deep cooling salt solution enters interchanger by brinepump, in control process, cold damage is large, indirect control is unfavorable for producing adjustment, affects greatly by brinepump efficiency.This project utilizes liquefied ammonia proportion low, low-boiling feature, directly to sulphonation kettle cooling, eliminate brinepump to the restriction of producing, decrease the use of pump simultaneously, reduce equipment maintenance expense, simultaneously due to direct cooling, cold damage is little, stops 250KW ice maker one, more eliminate the pollution of deep cooling salt solution to environment, the target level of product quality of chemical industry can be reached completely.
Summary of the invention
The cold damage of control process is there is large for the prior art type of cooling, affect large shortcoming by brinepump efficiency, the invention provides sulfonation reaction method of cooling in a kind of acesulfame potassium synthesis technique, eliminate brinepump to the restriction of producing, reduce the use of brinepump, save a large amount of electric energy.
The object of the invention is to be achieved by the following technical programs, sulfonation reaction method of cooling in a kind of acesulfame potassium synthesis technique, it is characterized in that, adopt liquefied ammonia to replace deep cooling salt solution to enter interchanger as refrigerant directly to lower the temperature to sulphonation kettle, control sulfonation temperature in the kettle to meet the temperature requirement of sulfonation reaction by regulator solution ammonia flow.
Beneficial effect: by utilizing liquefied ammonia proportion low, low-boiling feature, takes away the heat of sulfonation reaction by the distillation of liquefied ammonia, reach the object of cooling.Compared with existing method of cooling, this invention removes brinepump to the restriction of producing, reduce the use of brinepump, save a large amount of electric energy.Reduce the equipment purchasing installation costs maintenance expense of salt water tank and dry type evaporating cold, decrease the annual calcium chloride of consumption and the use of soft water, eliminate the impact on environment in maintenance process.
