In various industrial applications, the presence of dissolved gasses in liquids can cause significant problems. These include corrosion, oxidation, and other detrimental effects on equipment and processes. To combat these issues, we use a degasser. Specifically, membrane degasification systems have become increasingly popular due to their efficiency and effectiveness. But why exactly do we use a degasser? This article will delve into the reasons behind the use of membrane degasification systems.
Understanding Membrane Degasification (MGD) Systems
Before we delve into why we use a degasser, it’s essential to understand what membrane degasification systems are. A membrane degasser or MGD is a device that removes dissolved gasses from liquids. The system works by creating a pressure differential across a semipermeable membrane. The dissolved gasses in the liquid are forced to pass through this membrane and are then vented out of the system.
Membrane degasification systems are widely used in various industries such as pharmaceuticals, food and beverage processing, water treatment plants, and more. They offer numerous advantages over traditional gas removal methods like vacuum towers or chemical treatments.
Preventing Corrosion and Oxidation
One of the primary reasons we use a degasser is to prevent corrosion and oxidation in industrial processes. Dissolved gasses like oxygen and carbon dioxide can react with metals used in equipment or piping, leading to corrosion over time. This not only reduces the lifespan of these components but can also lead to leaks or failures that disrupt operations.
Similarly, oxygen can react with certain chemicals or substances during processing, leading to unwanted oxidation reactions. By removing these glasses using a membrane degasifier, industries can protect their equipment and ensure that their processes run smoothly without any interruptions caused by corrosion or oxidation.
Improving Product Quality
Another reason why we use a degasser is to improve the quality of the final product. In industries like food and beverage processing or pharmaceuticals, the presence of dissolved gasses can affect the taste, appearance, or even the shelf life of products. For instance, in beer brewing, excess oxygen can lead to off-flavors and reduced shelf life.
By using a membrane degasification system, these industries can ensure that their products meet the highest quality standards. The removal of dissolved gasses helps maintain consistency in taste and appearance while also extending product shelf life.
Enhancing Efficiency in Water Treatment
In water treatment plants, membrane degasification systems play a crucial role in enhancing efficiency. Dissolved gasses can interfere with processes like reverse osmosis (RO) and electrodeionization (EDI), reducing their effectiveness and increasing energy consumption.
By removing these gasses before they reach the RO membranes, degasifiers help maintain high operational efficiency. This not only reduces energy costs but also extends the lifespan of RO membranes by preventing fouling caused by gas bubbles.
MDG systems are often used as a process between reverse osmosis and electrodeionization to remove CO2 gas. CO2 gas has an anionic load. Removing CO2 improved electrodeionization water quality.
Closing Thoughts
In conclusion, we use a degasifier for several reasons – from preventing corrosion and oxidation to improving product quality and enhancing efficiency in water treatment processes. Membrane degasification systems provide an efficient and effective solution for removing dissolved gasses from liquids.
Their widespread use across various industries is testament to their importance in maintaining equipment longevity, ensuring high-quality products, and promoting efficient operations. As technology continues to advance, we can expect these systems to become even more integral to industrial processes worldwide. Contact us today to learn more!
