El control del pH en el agua de proceso puede reducir costesA French refinery acquires the InPro4260 electrode because it satisfies the requirements of large number of chemical processes
Control of pH in the process water can reduce costs
September 9, 2010
Water is a necessary process in refineries, but in certain processes, if not regulated properly its pH, resulting corrosion requires a high degree of maintenance. The new InPro4260 electrode helps reduce maintenance costs in a significant way in two refineries.
PH measurement is vital
Water is a vital player in the refinement of petroleum. However, due to the large amount of contaminants in oil, water is one of the main causes of corrosion in oil refineries. Precise control of the pH of the water of process can significantly reduce the corrosion in several key processes.
The problem
It's a French refinery as part of a large oil group. Installs a loop of pH in the interior of the water of the tank top condenser, which is a classic implementation which is notoriously problematic. Parts of the upper section of the Tower of distillation and condensing pipes suffer severely from corrosion if not properly controlled pH. Dissolve in water of process several contaminants such as sulfur, salts and mineral acids that are present naturally in the oil, and are highly detrimental in terms of pH low and high.
The client had already installed a loop of measurement of pH of the competition, but the electrode needed maintenance and daily cleaning, with what the measurement was not reliable.
The company wanted a few electrodes that were reliable, accurate, and need less maintenance, i.e. that were less susceptible to inlays
The solution
Mettler Toledo proposed the InPro4260 electrode. The pH electrode meets the requirements of large number of chemical processes, guaranteeing excellent performance in a wide variety of applications. Improvements to our reference of Xerolyt solid polymer electrolyte makes it well prepared to deal with difficult applications in the petrochemical industry.
Electrode InPro4260 of Mettler Toledo.
The InPro4260 electrode with Xerolyt Extra polymer has the following advantages:
-High performance in a range of 0 to 14 pH
-Minimum maintenance costs due to solid polymer frame
-Greater longevity in acidic environments / Basic or in the presence of organic solvents
-Lower maintenance: an electrolytic auction is not necessary
-Integrated temperature sensor: its positioning in the glass membrane ensures a fast and reliable temperature measurement
-Thanks to the Union between the means of measurement and the electrolyte of reference (the absence of diaphragms means that you there is no lock) are possible reliable measurements in highly contaminated media, or those with a protein content, as well as in suspensions and emulsions
Longer duration with a lower maintenanceThe high expectations of the customers were satisfied during a test phase in which the following results were obtained:
In comparison with the competition, the InPro4260… electrode
-It turned out to be the most resistant to the inlays
-It had a significantly greater period
-yielded more accurate measurements
-only had to be cleaned once every month or two months
The customer bought electrode of Mettler Toledo and even reported one of its partners in the petrochemical sector on the benefits of the same. This refinery also placed an order for the InPro4260. You have now installed the team and the measurement of pH is working perfectly for the total satisfaction of both clients.
