Executive Summary

SENTRO Technologies offers Energy Saving Technologies for Oil refineries, Petrochemical industries, Oil and Gas production facilities, Exploration units, Power plants and related industries.

We are an international company who developed a unique On-Line chemical cleaning method, to be applied in process furnaces, steam boilers/generators and air coolers in the Oil & Gas and Power industries.

We specialize in On-Line chemical cleaning of:

• Refinery Furnaces: both Radiant and Convection sections. Furnaces can be operated by gas or by oil or a combination.
• Steam Boilers: Cell, Convection and Economizer sections.
• Air Coolers: Forced or Induced draft.

Our cleaning methods will improve the total efficiency of the furnace/boiler/air cooler by increasing the heat transfer factor.

“On Line cleaning” means – during normal operating conditions of the equipment. No need to stop the furnace or the boiler or the air cooler.

Sentro will provide you a full “turn-key” service which includes: skilled manpower, equipment and chemicals, to perform the project from start to finish. The cleaning is guaranteed to remove layers of organic and inorganic dirt, such as:

Hydrocarbons components coming from the fuel, asphaltens, polymers, sulforic components
Coke and Ash
Corrosion scale, mainly irone oxide.
Other inorganic scale, minerals, salts
Inert materials from the refractory, such as ceramic fiber
Other materials sucked from the atmosphere such as plans, feathers, dust etc...


Main benefits of cleaning the furnaces/boilers and keeping a periodic cleaning schedule are the followin:


> Maintain high efficiency of the furnace/boiler, which means:
- Reduce temperature profile (cell, bridge wall, stack)
- Low energy consumption,
- Option to increase throughput if desired,
- Low emission rate (pollution),
- Low heat loss via furnace walls and stack.

> Avoide maintenance costs related to off-line cleaning (such as: scaffolding etc..)

> Avoid non-production costs when the furnace/boiler is not working

> Remove hidden and exposed corrosion scale

> Extend life of the tubes

> Avoid “hot spots”

> Avoid wall thickness problems, cracks and holes

> Avoid damage to refractory when cleaning mechanically off-line
