Working agent heating unit
The working agent heating unit is used at the oil and gas field sites to ensure the technological process of increasing the working agent temperature.
Various process media can be used as an agent (produced water, process water for heating, water-oil emulsion).
Heating of the working agent is carried out on a standalone heat exchanger.
Flue gases formed during combustion of a gas flow in a standalone vertical chamber are used as a heat carrier.
Main burners are located in the lower part of the combustion chamber, on which the gas flow is ignited.
Flue gases are supplied to the heat exchanger through the gas duct with the help of the fan provided by design. Flue gases not used for heating escape through the upper part of the chamber into the atmosphere due to natural draught.
Depending on the design, the unit may include one or more heat exchangers. At the same time, media with different properties can be heated on each of them.
Standard composition of the unit
- vertical chamber
- main and pilot burners
- Heat exchanger and fan system
- gas ducts
- instrumentation, control and regulating equipment
- stairs and service platforms
- process control system
The operation mode is standalone, it does not require the constant presence of personnel. As part of the supplied equipment, the necessary list of control, instrumentation and shutoff equipment is provided to ensure operation of the system. The heating unit is developed individually, based on the initial data on the parameters of the burned gas and the heated medium, and is designed for 24-hour and year-round operation.
Design features
In the entire range of discharges, the combustion process takes place inside a closed combustion chamber without visible flame and without the effect of thermal radiation on surrounding objects.
The design of WAHU allows to ensure a low noise level, the lowest possible level of emissions into the atmosphere, as well as the possibility to control and maintain critical elements of the unit (burners, instrumentation and control, shutoff and control valves) without stopping it and shutting it down for maintenance.
Advantages
- Involvement of flare gases in the technological process for heating the working agent
- Smokeless burning of discharges in a wide range of unit performance
- Low noise level
- Minimum level of emissions into the atmosphere
- No thermal radiation and visible flame
- Possibility of placing the unit near other production facilities
- The possibility of servicing the unit without stopping it and shutting it down for maintenance
