Description

Technical Field

[0001] The utility model relates to the technical field of a distillation kettle for producing a pour point depressant, and more specifically, relates to a distillation kettle for producing a pour point depressant. Background Art

[0002] In the existing technology, the distillation kettle for producing pour point depressants is a common equipment in chemical production. Its core function is to purify or separate different components in a mixture through a distillation process. The distillation kettle needs to withstand a certain internal pressure during operation. This is because the boiling point of the liquid increases with the increase of pressure during the distillation process. In order to achieve effective separation, it is often necessary to operate under a certain pressure. However, if the pressure inside the distillation kettle exceeds the safe range that the equipment can withstand and the pressure is not released in time, it may cause equipment damage or even serious accidents such as explosions. This will not only threaten the safety of the operators, but may also lead to production stoppages, increased equipment maintenance costs, and reduced production efficiency.

[0003] In addition, the pressure control of the still is not only related to the safety of the equipment, but also directly affects the effect of distillation. If the pressure cannot be maintained within the appropriate range, it may affect the boiling point of the liquid, and thus affect the effect of distillation separation. For example, too high a pressure may cause some components to fail to boil fully, thus affecting the purity and yield of the product; while too low a pressure may lead to over-boiling, resulting in energy waste and unstable product quality. Therefore, precise control of the pressure of the still is crucial to ensure product quality and optimize the production process. Utility Model Content
