Project Description

The Xingang Oilfield Heating Device Project was developed for an oilfield gathering and transportation system that needed a cleaner, easier-to-operate alternative to conventional steam heating. In the local desert and winter environment, the original steam-boiler heating route created high fuel consumption, long steam-network heat loss, water-treatment work, and frequent maintenance pressure.

XGTHERMAL supplied vacuum phase-change electric heating equipment for steam-heating replacement. The system uses indirect heat transfer, automatic temperature control, and remote communication to stabilize oil and gas gathering temperature while reducing boiler-room dependence, on-site operating workload, and repeated hot-washing maintenance.

Project Configuration

The public case page keeps the configuration at a safe disclosure level: enough for technical understanding, without exposing unnecessary internal operating details.

Operating Duty

Process target: Replace steam heating for oilfield gathering and transportation heating
Site condition: Outdoor oilfield operation with cold winter temperatures and desert wind exposure
Heating objective: Improve flow assurance, reduce wax deposition risk, and keep production temperature stable

Heater Package

Equipment type: Vacuum phase-change oil and gas electric heating device
Heat-transfer method: Vacuum phase-change heat transfer with an intermediate working fluid
System benefit: Electric heating elements remain physically isolated from the oil and gas stream

Controls & Safety

Control mode: PLC-based automatic temperature control with local operation interface
Communication: SCADA-ready operation through standard industrial communication
Protection: Overtemperature, overpressure, no-flow, leakage, phase-loss, and emergency shutdown logic

Challenge

The retrofit needed to reduce the cost and complexity of steam heating while keeping oilfield production temperature stable in a low-temperature operating environment.

Steam networks created heat loss across long outdoor pipe runs
Boiler rooms required fuel, water treatment, exhaust handling, and staffed operation
Low-temperature operation increased wax deposition and blockage risk
The customer needed a safer, more automated heating package for field operation

Solution

XGTHERMAL used vacuum phase-change electric heating with indirect heat transfer, stepless power regulation, and integrated protection logic.

Steam-heating replacement with electric heating and no boiler-room dependency
Vacuum phase-change heat transfer for uniform and efficient heating
Automatic outlet-temperature control for stable operation
Remote monitoring and safety interlocks for unattended field duty

Why the Oilfield Replaced Steam Heating

Conventional steam heating is familiar in oilfield production, but it often becomes expensive in scattered well-site and gathering applications. Heat is lost through steam pipelines before it reaches the actual heating point, and the boiler system brings additional fuel management, water treatment, blowdown, exhaust, and maintenance work.

For this project, the core value of the electric heating package was not simply replacing one heat source with another. It helped simplify the heating process, remove supporting steam infrastructure from the operating chain, and make heating output easier to match with real production demand.

Vacuum Phase-Change Heat Transfer

The heater uses an intermediate working fluid in a vacuum phase-change cycle. Electric elements heat the working fluid, vapor transfers heat to the process coil, and the condensate returns by gravity for repeated circulation. The oil and gas stream is heated indirectly, while the electric heating elements remain isolated from the process medium.

This structure improves heating uniformity and reduces local overheating risk. For crude-oil and mixed oil-gas applications, a longer internal heat-transfer path and spin-flow strengthening help increase residence time and heat exchange intensity, supporting stable outlet temperature under changing field conditions.

Reduced Heating Cost and Maintenance Load

Based on the project material supplied to us, the retrofit was reported to reduce annual steam-heating cost by approximately RMB 6 million. The value came from multiple sources: reduced fuel use, fewer steam-network losses, simplified auxiliary systems, lower routine maintenance, and less production disturbance caused by heating-related fouling or blockage.

Equally important, the electric heating route allowed the field team to operate with clearer automation logic. Temperature, pressure, power status, alarms, and remote commands can be integrated into the station control environment, enabling SCADA-ready operation and reducing manual intervention.

A Replicable Flow-Assurance Solution

This Xingang Oilfield case provides a practical reference for oilfields that want to move from fuel-fired steam heating toward electric, automated, and lower-maintenance heating. The same design logic can be adapted to crude-oil gathering, oil-gas-water mixed flow, wellhead insulation, and gathering and transportation heating in other cold or remote oilfield environments.

By combining indirect phase-change heating, automatic power regulation, explosion-proof electrical design, and remote monitoring, XGTHERMAL can support oilfield customers that need safer and more efficient heating packages for long-term production.
