Prepare

Descaling of equipment

Remove mineral deposits with chemistry tailored to their nature, the materials, and your installation.

Scale consists of adherent mineral deposits, notably formed by precipitation from water or process fluids. Their nature depends on the composition of the fluids, the process, temperature, and operating conditions.

Key considerations

Benefits of the treatment

Identify the deposit

Characterize the fouling to select an appropriate treatment strategy.

Control the chemical action

Select chemistry that is effective on the deposit while ensuring compatibility with the exposed materials.

Restore cleanliness

Remove deposits and prepare the equipment to continue operation or for subsequent treatments.

Your need

When should you intervene?

These deposits can foul surfaces, reduce heat transfer, disrupt flow, or complicate cleaning operations. Removing them first requires understanding the nature of the deposit before selecting the appropriate treatment.

Our approach

Understand the deposit before treating it

Effective descaling is not based solely on choosing a product. The nature of the deposit, the material, the equipment geometry, and operating conditions guide the treatment strategy.

Examine the deposit

Observe the fouling and gather the installation history.

Define the chemistry

Select the treatment based on the nature of the deposit and material compatibility.

Descale & rinse

Implement the defined sequence and remove treatment residues.

Verify the final condition

Examine accessible surfaces, verify the agreed criteria, and document the results as well as the limits of the inspection, in order to prepare the decision to return to service.

Understanding descaling

Not all deposits are scale

A discoloration, mark, or visible deposit is not sufficient to identify its nature. Depending on the installation and its history, the observed alteration may in particular be related to a mineral deposit, process residues, or a change in the surface condition of stainless steel.

Differentiate the deposit to target the treatment

A mineral deposit, oxides related to rouging, organic residues, or weakly adherent particles may coexist within the same installation.

Identifying them makes it possible to define an appropriate strategy: descaling, derouging, degreasing, or a sequence combining several operations, depending on the nature of the deposits and the exposed materials.

The initial assessment thus avoids choosing a formulation based solely on the deposit’s appearance.

Chemistry tailored to the deposit and the material

The composition of mineral deposits can vary. The chemical strategy is therefore defined according to the compounds to be removed, their adhesion, the material, and the intervention conditions.

Depending on the need, Technochim selects formulations and chemical agents suited to dissolving or removing deposits, seeking treatment effectiveness while controlling compatibility with exposed surfaces.

The implementation parameters are then adapted to the installation: concentration, temperature, contact time, circulation, and rinsing are defined according to the selected treatment.

Technochim expertise

Chemistry starts with identifying the deposit

Technochim combines materials knowledge, understanding of deposits, and mastery of chemistry to define the treatment appropriate to the equipment’s actual condition.

The objective is not to systematically apply a descaling product, but to select the chemistry and intervention conditions suited to the deposit encountered and the material to be preserved.
