Services

Online (in-process) Dry Chemical Cleaning of Furnaces, Heat Recovery Systems, Air Pre-heaters, Boilers

Online (in-process) dry chemical cleaning of heater and boiler tubes (external fire-side of the tube), through non-hazmat SENTROMAXTM dry chemicals, for both radiant and convection sections in furnaces, as well as furnace, superheater and economizer in boilers.

 

  • Conducted “on-the-run” during normal operating conditions with no loss of production

  • Flexible scheduling for the cleaning – limited equipment access required

  • Immediate measurable results and benefits – visible operational improvements while undergoing cleaning process:

    •  Stack temperature reduced

    •  Fuel consumption reduced

    •  Production rate increased

​

✔️ No damage to tubes, refractory, or instrumentation

✔️ No negative impact on SCR or other NOx reduction systems  

✔️ Mechanical and chemical cleaning occur simultaneously, as compared to dry ice or walnut blasting that act mechanically and are low effective methods

✔️Little or no scaffolding is required – typical access from existing platforms

✔️No cleanup required – non-hazmat SENTROMAXTM chemical decomposes into gas and exits heater in flue gas

✔️Green Solution – No negative environmental impact

✔️No confined space entry

✔️Significantly increased accuracy of IR thermographic readings of tubes skin temperature

Online (in-process) Dry Chemical Cleaning of Air Coolers

​

Online (in-process) dry chemical cleaning of fin fan air cooler finned tubes  (external air-side of the tube), through pneumatic spraying of non-hazmat SENTROFINTM dry chemicals, applicable for both induced and forced draft finned tube bundles, in a horizontal or vertical configuration.    

  • Conducted “on-the-run” during normal operating conditions with no loss of production

  • Flexible scheduling for the cleaning – limited equipment access required

  • Immediate measurable results and benefits – visible operational improvements while undergoing the cleaning process:

    • Process outlet temperature reduced

    • Production rate increased

    • Fan speed (in variable speed motors) reduced

✔️ No damage to tubes, fins, motors, belts, bearings, or instrumentation as compared to dry ice blasting or to fin-foam-and-water cleaning or other cleaning methods, as the cleaning method is non-aggressive and does not use high-pH or caustic materials;

✔️ Little or no scaffolding is required – typical access from existing platforms

✔️ No cleanup required – non-hazmat SENTROFINTM chemical appears like steam, does not settle, and disperses away

✔️ Green Solution – No negative environmental impact

✔️ No confined space entry

Intelligent Pigging and Internal Pipe Cleaning Services

Sentro Technologies provides intelligent pigging and internal pipe cleaning services designed to efficiently clean the interior of pipelines while also providing inspection capabilities. Our advanced robotic pigging tools thoroughly clean pipeline walls, removing deposits, debris, and buildup that can impact pipeline performance

  • ​Deep cleaning of pipeline interiors – Our intelligent pigging robots effectively remove scale, rust, and other deposits from the inner surfaces of pipelines, ensuring smoother flow and optimal performance.

  •  Real-time monitoring – While cleaning, the robotic pig also captures real-time data on the internal condition of the pipeline, allowing for simultaneous inspection and reporting.

  •  Improved pipeline efficiency – By removing blockages and buildup, our service enhances flow rates, reduces pressure drops, and optimizes overall pipeline efficiency.

  •  Environmentally friendly cleaning – Our method uses no harsh chemicals, ensuring a safe and eco-friendly solution for maintaining pipelines.

  •  Minimal equipment access required – The flexible technology can navigate various pipeline configurations, and no major scaffolding or setup is needed for operation.

✔️ Precise targeting of contaminants – Our intelligent pigging system is designed to target and remove specific contaminants such as wax, biofilms, and sludge, improving the overall cleanliness and integrity of the pipeline.

✔️ Customizable cleaning tools – The pigging tools can be customized to fit different pipeline diameters and material types, ensuring a tailored solution for each cleaning project.

✔️ Reduced maintenance costs – By keeping the pipeline free of buildup, our service helps extend the lifespan of the pipeline and reduces the need for frequent maintenance or repair work.

✔️ No confined space entry
✔️ Efficient for long-distance pipelines – The technology is effective for cleaning and inspecting long stretches of pipeline in a single run, optimizing efficiency for large-scale operations.
