Why are different cold bath temperatures used when determining the boiling ranges of various petroleum products
Thread Content
The water in the cooling bath is adjusted to a certain temperature so that the vapors resulting from the boiling of the oil condense into a liquid within the condenser tube, allowing it to flow normally therein. The distillation rate is then checked and controlled based on the rate at which the condensed liquid flows into the graduated cylinder. The water in the cooling bath is adjusted to a certain temperature so that the vapors resulting from the boiling of the oil condense into a liquid within the condenser tube, allowing it to flow normally therein. The distillation rate is then checked and controlled based on the rate at which the condensed liquid flows into the graduated cylinder. The automatic distillation range analyzer integrates mechanical, optical, electronic, and computer technologies, along with a temperature sensing system, enabling it to automatically carry out the entire distillation process. Applied to the distillation properties of gasoline, diesel, kerosene, fuel oil, heavy oil, and other mineral oils at atmospheric pressure. It can be monitored by a computer (via wireless/wired communication, selectable by the user). It features a reasonable structure, stable performance, and simple operation, making it an ideal analysis and testing device.
You haven’t clearly explained, in terms of principle, the essential relationship and differences between the temperature of the coolant in the condenser during distillation, especially in Enth’s distillation method, and the boiling point of the oil being distilled. The material you have excerpted is rather unprofessional; from reading many of your posts, it’s clear that your knowledge of analytical chemistry and instrumental analysis is only superficial – not even a basic level. It would be best if the post you send was reviewed by colleagues in your company who are familiar with analytical chemistry and instrumental analysis, so that they can provide some suggestions.
