Analysis of corrosion rates in the chemical cleaning of nitric acid plants and recovery of platinum group metals.

The cleaning of nitric acid plants can deliver huge benefits for owners and operators, firstly by enabling significant value

recovery from the return of precious metals, but also from increased plant efficiency associated with the removal of scale and

deposits from the tube surfaces. Efficiency increases of up to 10% can be expected from successful cleaning operations.

One of the most common concerns when carrying out a clean down project is the chemicals and processes used for the

cleaning of onsite components. To help safeguard your assets, we have undertaken third party corrosion analysis on our bespoke process. As with any specialist service choosing the right contractor with the right skills is key.

These are Yara’s own comments confirming the high standards of the  R.S.Bruce team, the smooth on site delivery and the 10% increase in boiler efficiency following the clean.

This is to certify that Johnson Matthey PLC, in association with their sub-contractors R.S.Bruce Ltd., carried out a "non-destructive " cleaning of the nitric acid plant at Yara Ambes.

The on-site operation took 15 days to complete and the job was carried out to high professional standards for safety, quality and efficiency. The operation included the boiler exchangers but also the G/G exchangers. Since the cleaning of the plant, which was principally aimed at recovering precious group metals from the units. Mara are pleased to have recorded a 10 % increase in boiler efficiency. Yara are very satisfied with all aspects of the JM cleaning process.
