Cold and intense winds increase viscosity and reduce availability. See how High Performance Electric Tracing and Steam Tracing stabilize lines in Oil & Gas.
In assets of Oil & Gas, onshore e offshore, drops in ambient temperature and gusts of wind increase heat losses in the pipes. The fluid cools, a viscosity rises, the differential pressure increases, bombs leave the point and the plant faces alarms, flow reduction and unscheduled stops.
Elevated sections on pipe racks, open passages on platforms and transfer lines between tanking and cribs are especially sensitive, creating thermal gradients (hot/cold spots) that destabilize the process.
This guide shows how Tayga mitigates this pain essentially with industrial heating systems: Electric Trace e High Performance Steam Trace.
Where the problem appears most often
- Transfer lines (terminals, pipelines between tankage and berths).
- Process lines and utilities on platforms/FPSOs.
- Manifolds e skids with many accessories (valves, flanges, filters).
- Elevated sections exposed to the wind, subject to accelerated cooling.
- Jacketed lines operating close to the lower temperature limit.
Technical diagnosis: understand before acting
- Survey of critical lines
Fluent, maintenance temperature, tolerances, setpoints, stretches with greater exposure to wind. - Heat map in representative operation
Thermography and measurements along the line to locate cold spots and gradients. - Heating system inventory
Type (electric or steam), power/capacity per section, control zones, sensors, panels/frames, purgers (when steam). - Root cause
Differentiate:- Failures of thermal sizing (loss > heating capacity);
- Control and sensing inappropriate (sensor in the wrong spot, poorly adjusted algorithm);
- Installation out of practice (endings/derivations, curvature, seals);
- Utility conditions (electrical or steam/condensate) incompatible with real demand.
Consolidation of the diagnosis (suggested model): for each monitored line/point, register setpoint and operating range, observed variation, heating status (electric or steam dash), evidence (photos/thermography) and technical priority. The structure and units must be defined by plant engineering.
Strategies to stabilize viscosity
1) Thermal design that considers wind and exposure
- Recalculate you lose com as real premises: minimum temperature, wind speed, diameter/material, accessories and exposed sections.
- Define power per meter (Electric Trace) or regime/arrangement (High Performance Steam Trace) for the worst design condition, with technical margin.
- Plan independent zones for sections with different losses (height, vento, shading).
2) Critical point coverage
- Valves, flanges, supports, filters and instruments dissipate more heat: treat them with specific application of the trait and positioning of sensors that represent the real thermal risk.
3) Representative control and sensing
- To choose sensor that “sees” the process (tube or process; environment only when technically justifiable).
- Adjust band/hysteresis to avoid oscillations (call/off) that increase consumption and wear.
- Monitor current per circuit (electric), pressure/condensate (vapor) e tendencies temperature per zone.
4) Disciplined execution and validation
- Follow routes/spacings/curvatures according to design and manufacturer; seal correctly endings/derivations (electric).
- to insure tightness e efficient drainage of the condensate with purgers positioned and operational (vapor).
- Commission with clear criteria: functional testing, thermography e heating curve; registrar “as built”.
When to use Electric Trace
Ideal when searching control granularity by circuit/zone and direct integration with control panels. Suitable for lines subject to rapid environmental variation (vento, shading) and for fine setpoint adjustments in critical sections.
Technical points of attention
- Power per meter derived from thermal calculation; respect for maximum circuit length and to voltage drop.
- Electrical protections and grounding; consideration of starting current.
- Sensor placement e control logic coherent with the dynamics of the line.
- Sealing correct terminations/derivations to avoid moisture ingress.
- Electrical tests: continuity and insulation resistance (megometer) before and after line closure.
When to use High Performance Steam Stroke
Suitable for plants that have steam/condensate and demand high thermal capacity and uniform temperature distribution in great lengths. Tayga's solution was developed to overcome limitations of conventional tracing, focusing on efficiency, thermal stability and less maintenance intervention.
Technical points of attention
- Steam regime/pressure compatible with the calculation; hydraulic arrangement that ensures stable power supply.
- Efficient condensate drainage with properly selected and positioned traps.
- Watertightness connections before departure.
- Accessibility to inspection and testing points.
- Passage/Drain Tests and thermal validation in commissioning.
The choice between Electric Trace e High Performance Steam Trace could it be hybrid by area/service, according to your plant’s technical criteria.
Maintenance and operation
- Electric Trace: visual inspections of boxes/terminations; continuity e megometer newspapers; checking alarms and current trends per circuit.
- High Performance Steam Trace: checking purgers and drainage; connection inspection; verification of thermal stability in regime.
- Performance tracking (define with plant engineering): stability indicators by zone, temperature alarm/event trends and typical warm-up time until regime.
Frequency and acceptance criteria must be defined by the plant engineering, according to criticality and environment.
