Refineries

Large volumes of water are employed in refining processes, especially for cooling systems, distillation, hydrotreating and desalting.

A wide variety of contaminants are often present in refineries’ wastewater including  high COD and BOD, large amounts of suspended particulate matter, oil and grease, sulphides, ammonia, heavy metals, etc.

Elgressy understand that the supply of properly conditioned water has a crucial influence on productivity and process quality, and offer customized solutions for numerous water treatment applications:

Wastewater treatment – EEC/EEO:

Elgressy designs and manufactures electrocoagulation and
electro-oxidation systems for pre and primary treatments for various types of
refineries wastewater.

Advantages:

  • Cost effective and reliable- rapid return of investment.
  • Reduces maintenance, shut down time and labor costs.
  • Eliminates the need for expensive and harmful chemicals.
  • Very low life cycle cost and electricity consumption.

Cooling Tower treatment – EST:

EST provides a comprehensive and effective solution to the problems
associated with cooling towers, namely scale, corrosion and
biocontamination.

Advantages:

  • Cost effective and reliable- rapid return of investment.
  • Generates significant water savings
  • Eliminates the need for expensive and harmful chemicals.
  • Very low life cycle cost and electricity consumption.
  • Reduces maintenance, shut down time and labor costs.
  • Simple retrofit with small footprint.

Corrosion Prevention – ECP:

ECP is an effective and innovative electrolysis technology developed to protect the inner surfaces of hot and cold-water pipes and tanks against corrosion and scale.

Advantages:

  • Rapid results - Immediate prevention of new corrosion-accumulation and stoppage of “red water”.
  • Versatile – Effective in hot and cold-water systems, water tanks and all pipe composition.
  • Safe drinking water - no adverse effect on water quality or taste.
  • Low operational cost - low energy use and low water consumption rates.
  • Cost effective – low energy consumption, prevents blockages and equipment damage.
  • Very low life cycle cost and electricity consumption.

Minimizing risk of Legionella Pneumophila bacteria – LPB:

ECP is an effective and innovative electrolysis technology developed to protect the inner surfaces of hot and cold-water pipes and tanks against corrosion and scale.

Advantages:

  • Rapid results - Immediate prevention of new corrosion-accumulation and stoppage of “red water”.
  • Versatile – Effective in hot and cold-water systems, water tanks and all pipe composition.
  • Safe drinking water - no adverse effect on water quality or taste.
  • Low operational cost - low energy use and low water consumption rates.
  • Cost effective – low energy consumption, prevents blockages and equipment damage.
  • Very low life cycle cost and electricity consumption.
