With the continuous advancement of industrialization and technological progress, deep engineering manufacturing technology is becoming a proud technology in all walks of life. Deep engineering manufacturing often requires high purity metals, chemicals, or other materials, and distillation is an important process that can be used for purification processes that separate mixtures into different components. The principle of

distillation is based on the boiling point difference of different components. Under normal pressure, the boiling points of different substances are different, so that the mixture can be rigidly resolved into different components, and it can be carried out under low temperature conditions. People can use this principle to extract fresh water from seawater, extract petrochemical raw materials from crude oil, extract propane, ethylene and other products from natural gas, extract pure metals from metal ores, and so on.

distillation is a complex process, involving multiple steps such as preheating, steam generation, evaporation, condensation, diversion, recovery, etc. In practice, it is necessary to select suitable materials and process conditions according to the composition of different mixtures and their boiling point differences in order to maximize the efficiency of distillation. Among them, the most critical and often used is the fractionation tower, which has a vital position in the distillation process, greatly improving the separation efficiency.

In addition to the fractionation tower, there are some other terms and technical details that we also need to understand. For example, in the extraction of crushed stone, we need to use the method of combining polyoxanes (or aluminum chloride) to separate the scattered materials from water. This method takes advantage of the adsorption of polyalkane and water on the surface of the stone, so that after the water is evaporated, the remaining dry mixture is collected by a separation funnel or the like. In addition, we also need to pay special attention to the quality and ratio of materials, which is particularly important when determining the corresponding process and technical parameters.

In general, distillation is a very important process, which can be applied to the depth of engineering manufacturing in all walks of life. Understanding simple distillation principles not only improves our technical level, but also helps us to choose the best practices and process conditions, improve process efficiency, ensure product quality, and also contribute to environmentally friendly follow-up utilization, so we must master them. Terminology and technical details are worthy of attention and need our continuous accumulation and summary.
