Steam Heat Exchanger – Indirect Heater

Steam Heat Exchanger - Indirect Heater is used to heat the well effluent after it flows out of the well and prior to the separating process. This type of heat exchanger is also called a direct heating furnace which allows it to heat up the process coil directly. This is a kind of heating furnace that has the maximum heat exchange efficiency among the heating furnaces.

Steam Heat Exchanger

Steam-heat exchangers are used to raise 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.

Horizontal Separators

Horizontal separators are ideally suited to wellstreams having high gas-oil ratios, constant flow, and small liquid surge characteristics. Horizontal separators are smaller and less expensive than vertical separators for a given gas capacity. Liquid particles in the wellstream travel horizontally and downward at the same time as a result of two forces acting upon them-the horizontal force of the gas stream and the downward force of gravity.

Conditions Affecting the Design and Operation of Gas Dehydrators

The temperature of the glycol entering the contactor has a significant effect on the gas dew point depression and should be held to within 10oF above the inlet gas temperature. Higher glycol losses and higher outlet gas dew points occur when the lean glycol enters the contactor at a temperature more than 100F above the gas temperature
