Nucleation kinetics and polymorphism of calcium carbonate particles in natural gas production
Barland, Astrid Odland (Master thesis, 2012)Precipitation of calcium carbonate in pipes and process equipment is a widespread problem in natural gas production as we know it today. Studies of calcium carbonate systems are crucial to prevent this problem. When the ... -
Scaling of Calcium Carbonate at Heated Surfaces in a Continuous System
Nergaard, Margrethe (Master thesis, 2011)Scaling is the precipitation of a mineral layer on a surface. Sparingly soluble salts with inverse solubility, which calcium carbonate exhibits, will prefer precipitation at heated surfaces, making heat exchangers a target ... -
Scaling of Calcium Carbonate on a Heated Surface in a Flow Through System with Mono Ethylene Glycol.
Hyllestad, Ketil (Master thesis, 2013)Efficiency of industrial heat exchangers can be reduced due to precipitation of a solid mineral layer called scale. Reversibly soluble salts such as calcium carbonate are less soluble at elevated temperatures and therefore ...
