Steam Exchanger

Steam-heat exchangers are used to raising the temperature of well effluents to prevent hydrate formation, reduce viscosity, and break down emulsions for efficient separation of oil and water. Because steam-heat exchangers drastically reduce risk, they are used on offshore platforms and in other work conditions where safety regulations do not permit the use of indirect-fired heaters.
