Envirorisk Management have entered into a global partnership with Sentro Technologies to provide unique, safe and cost effective on-line cleaning technologies for the Oil & Gas and Power industries including:

• Refinery Furnaces: both Radiant and Convection sections (Furnaces can be operated by refinery/waste gas or by fuel oil or a combination)
• Steam Boilers: Fire Box, Convection, Economizer and Super Heater sections
• Air Coolers: Forced or Induced draft

The method uses non-toxic chemicals to clean refinery furnaces, steam boilers and air coolers while the plant is in full operational mode. It improves the total efficiency of the furnace/boiler/air cooler by increasing the heat transfer factor.

The complete “turn-key” service provided includes: skilled manpower, equipment and chemicals. The cleaning is guaranteed to remove:

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

The on-line chemical cleaning technology provides the following benefits:

• Maintains high efficiency of the furnace/boiler
• Reduced temperature profile (cell, bridge wall, stack)
• Reduced energy consumption
• Option to increase throughput if desired
• Reduced emissions rate
• Lower heat loss via furnace walls and stack
• Avoiding maintenance costs related to off-line cleaning (e.g: scaffolding, waste cleanup, etc)
• No down time and associated losses: cleaning completed during normal operating conditions
• Removing hidden and exposed corrosion scale
• Extended life of the tubes
• Avoiding “hot spots”
• Avoiding wall thickness problems, cracks and holes
• Avoiding damage to refractory when cleaning mechanically
