“…One of their major drawbacks is the fact that they are used in high concentrations (10-50 wt%) (Mizuta, 2006). The more the temperature and pressure conditions become sever, the higher the required concentration becomes.…”

Gas hydrates, also known as clathrate hydrates, are non-stoichometric crystalline compounds that have an "ice-like" appearance. They occur when water molecules hydrogen bond to form cavities that can be occupied by a gas or volatile liquid. The inclusion of these guest molecules stabilizes the water network. Hydrates are a nuisance to the gas processing industry as they plug pipelines and equipment which can upset daily operations and add unnecessary maintenance costs.In this work, kinetic experiments were performed on a methane-water system in the presence of Antifreeze Proteins (AFP`s) in order to elucidate their effectiveness as a kinetic hydrate inhibitor. The results were compared to experiments done with a classical

“…(2) Treated wells or subsea lines must not be shut-in for appreciable periods because KHIs then lose their effectiveness. (3) At extraordinarily high subcooling conditions of deep water operations, current state-of-the-art KHIs may be unable to sufficiently retard enhanced rates of hydrate crystal growth (Kelland et al, 2006b).

“…First, AA emulsifiers may facilitate water-in-oil emulsions, where the hydrate forms in the small water droplets within the discontinuous phase while surrounding emulsifier polymers segregate droplets to slow agglomeration (Kelland et al, 2006b;Behar et al, 1991;York and Firoozabadi, 2008)). The AA polymers have hydrate-philic head groups attaching to the hydrate-containing water drops and have hydrate-phobic tails extending into the continuous hydrocarbon phase (Huo et al, 2001).…”

“…158 There is research into creating biologically compatible and still cost effective alternatives, mostly focusing on neutral and zwitterionic compounds. 147 Kelland et al 159 It was found that zwitterions (25) are much more biologically compatible than the corresponding quaternary ammonium salt with free ions. 147 Unfortunately, their ability as an AA was significantly hampered by attaching the anion.…”

AbstractFossil fuels are still a necessary and important part of modern living, keeping cars running and houses heated for example. As demands have risen and reservoirs of oil and natural gas have depleted, it has become increasingly more important to tap in to fields that were once classified as undesirable. Sour fields, fields high in acidic gases such as hydrogen sulfide and carbon dioxide, are one such option. There are many difficulties and dangers associated with working sour fields, such as toxicity of the sour gases, hydrate formation and corrosion of equipment that have prevented these resources being used in the past. Many varied methods of overcoming these problems have been developed, from removing the sour components to inhibiting their effects. This review highlights the major issues raised by sour fields as well as a wide range of solutions in use today.
