The heater treater is normally found downstream of a two-phase separator on a high pressure system. It can be found downstream of the well, a free-water knockout or gun barrel on a low pressure system. Heater treaters are used where the emulsion cannot be broken using just retention, quiescence and chemical krasbas.
The Horizontal Heater Treater utilizes heat and mechanical separation enhancement devices, such as plate packs, baffles and electrostatic grids. The Horizontal Treater is designed to efficiently treat large capacities of crude oil by removing water and emulsion from the wellstream, preparing the treated oil for delivery.
The Vertical Heater Treater breaks emulsions in crude oil using heat and retention time. The Vertical Heater Treater efficiently helps remove water and emulsion from crude oil wellstreams, so you can keep your production flowing. Once the oil emerges from the treatment process, it is ready for further processing or pipeline delivery. The well stream first enters the emulsion inlet near the top of the unit and is diverted against the treater shell. Gas separates from the liquids, ascends and exits the unit. Warm vapor from the lower section flows up to the gas separation section and mixes with the cool inlet stream. Heavier components in the gas condense and descend.
In an oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production. This often happens during the transportation of petroleum products through pipelines and into vessels, such as when the stream from a common separation unit flows into an on-site atmospheric storage tank. A venting apparatus is used in these vessels to prevent damage due to increasing pressure, extreme cases of this are referred to as boiling liquid expanding vapor explosion BLEVE. The composition of the gas that is flashed is dependent on many factors, therefore it is suggested that all extractions be analyzed to determine accurate compositional values. The production of flash-gas and its release into the atmosphere, via venting and improper handling during production, is of concern to environmental efforts due to the presence of Hazardous Air Pollutants HAP , Greenhouse Gases GHG , and Volatile Organic Compounds VOC which have been suggested to have harmful long-term environmental impacts. Various efforts by organizations around the world have been made to develop appropriate guidelines for handling flash gas as well as tools for evaluating flash emissions through model based calculations. Natural gas liquids NGL are the fraction of the hydrocarbons , primarily having carbon atoms,  that are present in the flash gas during oil production or as liquids in natural gas production.
Jump to content. Low Flow in Pipes - posted in Ankur's blog. Posted 16 July - PM. I am final year undergraduate chemical Engineering. I am working on a project on heater-treaters. I have to calculate the heat transfer area and thus the length and diameter of the firetube in heating section of heater-treater by performing modelling and heat balance in heating section,. I am new to this equipment.
In oil and gas industry crude oil/water emulsions are normally encountered. This type of emulsion is called normal emulsion if water is dispersed phase and oil is.
Removing water from crude oil often requires additional processing beyond the normal gravity separation. Crude oil treating equipment is designed to break emulsions by coalescing the water droplets and then using gravity separation to separate the oil and water. In addition, the water droplets must have sufficient time to contact each other and coalesce.
Palastak, James E. Ohio, November With the depletion of gas reserves, the increase in commercial demand and the rising cost of natural gas, alternatives for a reliable, safe, economical and efficient method for preheating produced fluids in heater treaters is sought. A case history on the performance of an electric immersion heater versus a conventional gas firetube is presented under similar pumping and climatic conditions. The immersion heater uses the principle of resistive type of heating thermal energy. Some advantages of using electric immersion heater's are: They help reduce the possibility of fire or explosion hazards since there are no open flames.
Because gunbarrels tend to be of larger diameter than vertical heater-treaters, separation section removes flash gas and gas liberated as a result of heating.
