This customer has the excellent habit of inspecting storage tanks on a regular basis. In this case, the customer inspected the interior of a sulphuric acid tank and carried out work on the concrete tank.
Sulphuric acid is an inorganic acid with the formula H2SO4. It is an acid that can be mixed well with water. Sulphuric acid is colourless and odourless. It is one of the most important raw materials in the chemical industry.
PROBLEM:
The customer cannot simply take the existing tank out of service because the storage of sulphuric acid is necessary during the production process. The storage of sulphuric acid has special requirements. The customer was therefore looking for a temporary but reliable solution.
SOLUTION:
Rental tank with drip tray for 96-98% sulphuric acid.
This project had some specific requirements. Due to the good cooperation between Liqson and the client, this was all communicated clearly and in a timely manner.
36,000 LITRES IN STAINLESS STEEL 316
Sulphuric acid can also be stored in a steel tank, but stainless steel is recommended to ensure that the sulphuric acid remains of good quality.
Liqson also has a composite storage tank available for lower concentrations of sulphuric acid. These double-walled tanks are rapidly deployable and highly versatile.
Of course, the tanks can also be used for other acids, such as hydrochloric acid, nitric acid, formic acid, acetic acid, citric acid, etc.
INERTISATION
The storage tank was inertised by means of nitrogen. Allowing the sulphuric acid to come into contact with oxygen could reduce the concentration. The sulphuric acid could become more aggressive and affect the tank. The tank has been fitted with special ventilation to be able to implement this. The customer had nitrogen on this site. But Liqson also has the right partners for this.
BALL VALVES
For safety reasons, the customer only chose to work with ball valves. Ball valves have a larger sealing surface (compared to butterfly valves) and therefore seal longer and better. No problem, Liqson had the desired valves in stock.
HEIGHT
To pump the sulphuric acid easily, the customer expected the tank to stand at a height of 50 cm. We put the tank on a steel drip tray. In this way we can also catch possible leaks.
DIN VS ANSI
The customer works with ANSI flanges on this site. We provided the reductions and lapses free of charge so that the client did not have to provide any adjustments.
SEALS
The standard rubber seals were replaced by PTFE seals.
INSTRUMENTATIon
A tank with sulphuric acid must certainly not become too hot. To monitor this, the tank was fitted with a temperature measurement.
This storage tank was fitted with a digital level measurement. Here a radar level measurement was chosen with a display on the tank at eye level. This arrangement also has a 4-20 milliamp “off” signal. The customer can therefore lay a cable to their control room and monitor the level.
CLEANING
To ensure that the liquid retains its quality, the storage tank was professionally cleaned and dried beforehand. This was done before installation. One less worry for the customer. .
RENT
This customer opted for a rental solution for this project. This allows the customer to switch quickly and obtain a reliable installation. The customer does not need to invest and has a clear view of all costs. Liqson can offer rental tanks for the short and long term. Always at competitive prices and with the best service.
