A new generation of gas hydrate inhibitors
New, cost-effective, and environmentally acceptable hydrate inhibitors that allow multiphase fluids to be transported untreated over long distances have been under increasing investigation by the oil and gas industry. Replacing traditional hydrate inhibitors such as methanol and glycols with a new generation of hydrate inhibitors can lead to very substantial cost savings, not only for the reduced cost of the new inhibitor but also in the transportation costs and the size of the injection, pumping and storage facilities. Thus it is possible to redesign production facilities on a smaller scale. Such a change-over in hydrate inhibitor technology may also be an environmental requirement in the near future. We will present an overview of patent and other literature on new hydrate inhibitors, including specific chemicals that have been investigated. Our own results on some of these published chemicals will be given and their applicability compared. We will also present data on new inhibitors developed at RF, as well as improved methods of evaluating their activity. A discussion of the relative merits of the two main types of new hydrate inhibitor, {open_quotes}kinetic inhibitors{close_quotes} and {open_quotes}anti-agglomerators{close_quotes}, will be given.
