online chemical cleaning

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
