Abstract
In recent years, we have explored non-amide-based classes of kinetic hydrate inhibitor (KHI) polymers to determine if the same level of performance can be achieved as commercial KHI polymers, which...
Highlights
Plugging of flow lines by gas hydrates is one of the most serious production issues to consider during field development.[1]
We investigate a new class of nonamide kinetic hydrate inhibitor (KHI) polymer for the first time: polyvinylaminals
A light orange-brown solution was formed in the normal case, which was used for KHI testing
Summary
Plugging of flow lines by gas hydrates is one of the most serious production issues to consider during field development.[1] Various methods are available to avoid this problem, including the use of low-dosage hydrate inhibitors (LDHIs).[2,3] The two main subcategories of LDHIs are antiagglomerants (AAs) and kinetic hydrate inhibitors (KHIs). KHI products that can extend this limit would be very welcome as one need not worry about hydrate slurry transportation as with AAs, or melting the hydrates in the processing facilities
