Increased reliability of cooling water systems at lower OPEX

Page last modified
February 22 2024

The site-specific biocide dosing solution, 'Ecodosing', targets biofouling in once-through and open recirculation cooling water systems and prevents both macrofouling (shells) and microfouling (biofilms). The Ecodosing solution is delivered in combination with a monitoring system that can detect the onset of biofouling in an early stage and with high accuracy. The total solution will maintain the integrity of the cooling water system, thereby significantly increasing the uptime of the oil & gas processes it supports, while lowering the OPEX related to biocide dosing.

The solution has been successfully implemented since 1998 mostly in Europe and the Middle East with clients in the oil & gas industry, power industry, and desalination industry. Operators that have deployed the technology have seen reductions in cooling water system leak frequencies as high as from 20/yr to zero/yr.

Pros & Limitations
1
Estimated increase in system reliability (uptime): 10-30%
1
Reduced biocide use by 30-60%, leading to OPEX cost reductions of >€250k/year
1
Acknowledged by the EU and RSB (Abu Dhabi) as Best Available Technique
1
Average pay-back time of the investment: 3 months to 1 year
1
Environmental benefits in terms of energy consumption and discharge water quality
1
Reduced CO2 emissions (1.000 kton - 5.000 kton per year)
0
1-3 months study required to understand seasonal variability of the biological content of the local surface water
Specification
Specification Title Specification Description
Accuracy
The solution is based on accurate site-specific conditions like species and seasonal changes.
Areas of Application
Industrial cooling water systems.
Capacity
Reduced biofouling leads to higher production capacity (debottlenecking).
Collaboration
The solution is developed in collaboration with site staff, chemical suppliers and local experts.
Impact
Increased system reliability (uptime): 10-30%.
Implementation time
Implementation can be within 3 months.
Insight
The biomonitors provide real-time insight in the effectiveness of the (current) dosing method.
Maintenance
Reduce maintenance as cooling water system stays clean (extended inspection intervals).
OPEX
OPEX can be significantly reduced (€500k per year - €1M per day).
Return on Investment
The average payback time of the ecodosing solution is 3 months – 1 year.
