Project overview ## Electric heating at the point of use. This oilfield application required an alternative to conventional steam heating for gathering and transportation duties in a cold outdoor environment. XGTHERMAL supplied vacuum phase-change electric heating equipment for the retrofit.

The engineering challenge ## Rethinking the steam-heating route. The existing route involved a steam heat source, distribution pipework and supporting services. Outdoor steam distribution added heat loss, while boiler operation brought fuel handling, water treatment and maintenance requirements. The retrofit needed to maintain gathering and transportation temperatures through cold winter conditions and desert wind exposure. Reducing steam-network losses and auxiliary maintenance had to be considered alongside wax deposition, blockage risk and changing production demand. Equipment configuration ## A 260 kW-class indirect heating package. The supplied heating equipment combines vacuum phase-change heat transfer with automatic control for outdoor oilfield service. Heating capacity 260 kW-class heating package Process service Oil and gas gathering & transportation Heating route Electric, indirect vacuum phase-change heat transfer Control PLC-based automatic temperature control with local interface Monitoring SCADA-ready remote monitoring Protection Overtemperature, overpressure, no-flow and electrical protection Our approach ## Heat transfer, controls and integration. The engineering approach addresses process-stream isolation, heating uniformity and the control requirements of an oilfield retrofit. ### Indirect heat transfer Electric elements heat an intermediate working fluid. Vapor transfers heat to the process coil, and condensate returns by gravity. The elements remain isolated from the process stream. Vapor condensation transfers heat to the coil, supporting more uniform heating and reducing direct exposure of the process fluid to electric-element surface temperatures. ### Temperature control PLC-based automatic temperature control regulates heating output around the required process temperature. A local operator interface and SCADA-ready communication support field operation and remote monitoring. ### Field integration The equipment arrangement brings the heat source closer to the heating duty. Process and electrical protection are integrated with station controls, including overtemperature, overpressure and no-flow protection. Detailed trip settings remain specific to the installation. Project value ## Beyond replacing the heat source. ### Simpler heating infrastructure The electric heating route reduces dependence on a boiler room and distributed steam services. Indirect heat transfer separates the electric elements from the oil and gas stream, while automatic regulation supports the required operating temperature. ### Energy and operating cost Project materials report annual steam-heating cost savings of approximately RMB 6 million. This is a project-specific reported figure, rather than a guaranteed saving for other installations. The reported benefit combines changes to fuel consumption, steam-distribution losses, auxiliary services and maintenance. It is not an efficiency measurement for an individual heater; comparison depends on the original steam system, operating hours, energy prices and heating demand. ### Operation and maintenance Local operation and remote monitoring bring temperature, pressure, power status and alarms into the station operating environment. The retrofit provides a practical reference for reviewing boiler support, steam-network maintenance and heating-related production interruptions alongside the required process duty.
