Kinetic hydrate inhibitors (KHIs) have been used for several decades to solve the hydrate
formation problem in oil and gas flowlines. Traditional KHIs are amide-based polymers, eg …

This paper briefly reviews gas hydrate nucleation, dissociation, and hydrate inhibition by
kinetic hydrate inhibitors (KHIs). The drawbacks of traditional inhibitors and the testing …

Kinetic hydrate inhibitors (KHIs) have been used in the upstream petroleum industry for
about 25 years to prevent plugging of flow lines with gas hydrates. The main ingredients in …

Gas hydrate plugging and corrosion are two major flow assurance problems in oil and gas
transmission pipelines. Since an incompatibility problem can occur during the simultaneous …

Low-dosage hydrate inhibitors (LDHIs) are used to prevent gas hydrates from plugging
upstream gas and oil flow lines. LDHIs come in two main classes, kinetic hydrate inhibitors …

This study is devoted to the evaluation of vegetable oils (in this case castor oil) as an
inexpensive, sustainable, environment-friendly, natural and promising resource to …

Current schemes dealing with hydrate blockage problems in gas pipelines suffer a high
dosage of inhibitors and thus are associated with a significant risk of environmental damage …

Most polymers used in commercial kinetic hydrate inhibitor (KHI) formulations show
thermoresponsive behavior in aqueous solution. This means that they exhibit a cloud point …

The unusual behavior of a new class of compounds that selectively function as either
promoters or inhibitors of gas hydrate formation depending on the process conditions has …

Antiagglomerants (AAs) are surfactants used in the upstream oil industry to prevent gas
hydrate plugging in flow lines. Most, if not all, AAs used in the field today are cationic …
