Steam is integral to many industries, from providing power for turbines to sterilizing equipment in the healthcare industry. This versatile gas can either be pure steam or clean steam, each with its unique properties and benefits. This article will explore pure and clean steam, the difference between the two, and why each type is important.
What are the characteristics of each steam?
Pure steam is steam that has been specifically treated to remove all impurities, while clean steam is steam that has been treated to remove most impurities. There are a few key differences between pure and clean steam, which are important to understand to choose the right type of steam for your needs.
Pure steam is generated by boiling water and is 100% saturated vapor. Clean steam is generated by heating water to its saturation point and passing it through a steam generator. The steam generator removes any contaminants that may be present in the water, such as minerals, bacteria, and dirt. Pure steam is often used in food processing because it is less likely to cause contamination. It is also less likely to cause corrosion and can be used at higher temperatures than clean steam. Clean steam is often used in sterilization because it is less likely to leave behind residue.
Are Pure Steam and Clean Steam the Same?
The main difference between pure and clean steam is that pure steam is free from any contaminants, whereas clean steam is not. Pure steam is generated by vaporizing water and does not come into contact with any surfaces before reaching the equipment, ensuring there are no contaminants in the steam. On the other hand, clean steam is generated by vaporizing water that has been in contact with surfaces. It means that there is a potential for contaminants to be present in the steam. The advantage of using pure steam is that it is guaranteed to be free of contaminants that could potentially affect sterilization. The disadvantage is that it is much more expensive to generate and store than clean steam. The advantage of using clean steam is that it is almost as effective as pure steam in sterilization but is much less expensive to generate and store. The disadvantage is there is a risk of equipment contamination.
In conclusion, pure and clean steam are both important for different applications. Pure steam is essential for applications where cleanliness is critical, while clean steam is sufficient for applications where cleanliness is not critical.
