| dc.description.abstract | Low dosage hydrate inhibitors are an economical alternative to thermodynamic inhibitors, like ethanol and glycols, to prevent the occurrence of gas hydrates in gas and oilfields. A class of low dosage inhibitors, kinetic hydrate inhibitors, have been commercially used in the field for over 15 years. The developments and search for new and better kinetic hydrate inhibitors is still an ongoing process.
This thesis describes how a high pressure rocking cell, RC5, can be used to test the KHI performances and rank them based on effectiveness and efficiency.
The first part of this thesis is the Poly (2-dialkylamine-2-oxazoline) polymers, a new subclass of amphiphilic polymers. These polymers were made by Richard Hoogenboom and his research team in Belgium, hence why it`s called the “Hoogenboom” project. They were delivered to us for testing their KHI performances.
The second part of this thesis is the PVAmOx-syntheses. These products were made from scratch using different molecular weighted Lupamines as the base. The KHI performance was tested after the syntheses was made. Several polyamine oxides have been investigated as KHIs, and several of them we made showed good KHI performance.
Both the Poly (2-dialkylamine-2-oxazoline) and PVAmOx-reactions were tested with different volumes, concentration, synergists were used, and different gases. | |
