1、 Industrial waste gas recovery: In the vast production system of the chemical industry, numerous chemical reactions produce a large amount of waste gas rich in carbon dioxide. For example, combustion or synthesis processes using coal, oil, and natural gas as raw materials result in high levels of carbon dioxide in the exhaust gas. If these industrial waste gases are directly emitted, it will not only exacerbate the greenhouse effect, but also be a waste of resources. Nowadays, advanced recycling technology can accurately capture carbon dioxide in exhaust gas. Through strict purification processes, impurities such as sulfides, nitrogen oxides, and dust are removed to meet the purity standards for making dry ice, achieving the goal of turning waste into treasure.
2、 The purity of raw materials is crucial: not all carbon dioxide can be directly made into dry ice, purity plays a critical role. Even trace impurities can cause problems during the formation of dry ice or subsequent applications. For example, excessive moisture can cause frost and adhesion on the surface of dry ice during storage, affecting its effectiveness; Impurities such as sulfur and phosphorus may contaminate the preserved items in food preservation scenarios, posing a threat to human health; In industrial cleaning, impurity particles may scratch the surface of the cleaned object. Therefore, regardless of the source of carbon dioxide raw materials, the purification process should not be underestimated. Only by ensuring high purity can high-quality dry ice be produced, meeting the strict requirements of various industries for dry ice performance.
By understanding the raw materials used in dry ice production and the techniques behind it, we can better understand that this seemingly simple solid substance is actually a crystallization of technology and resource recycling. With its unique charm, it continues to add color and assistance to our lives and production, and carbon dioxide, as a raw material, has also completed a magnificent transformation from “exhaust gas” to “magical refrigerant” on the stage of dry ice.http://www.ntpco2.com
