Features & Benefits
- Ready-to-Use Product Features
- Advantages
- Cleaning and pickling objects include: evaporators, steam boilers, heat exchangers, piping systems, and all types of thermal equipment.
- Particularly noteworthy is the ability of LITHSOLVENT EB to reduce the diffusion of hydrogen into the steel to a minimum, thus avoiding pickling brittleness (cf. DRAHT, 7. 35/38. 1956).
- Advantages of LITHSOLVENT Cleaning Concentrates
LITHSOLVENT cleaners are intended for customers who do not have the option to prepare their own cleaning solutions. Generally, they are inhibited methanesulfonic, formic, hydrochloric, amidosulfonic, citric and phosphoric acids, formulated for different cleaning temperatures and materials.

- Applications
- LITHSOLVENT EB is a highly efficient inhibitor formulation for the protection of metal materials during the chemical cleaning or pickling with hydrochloric acid and mixtures of hydrochloric acid/hydrofluoric acid at temperatures up to 100°C.
- LITHSOLVENT EB contains a combination of specifically acting inhibitors and special surfactants with a high wetting effect. As a consequence a quick wetting of the surfaces to be cleaned is ensured.
- Cleaning and pickling can be executed on the following installations: evaporators, boilers, heat exchangers, piping systems and thermic apparatus of all kinds.
- LITHSOLVENT EB protects all metal materials which are present in the boiler and apparatus construction on the basis of iron, chrome and chrome-nickel steels as well as copper and brass (particularly in contact with steel). The working temperature for standard steel and stainless steel is max. 100°C, for cast iron max. 60°C.
- Zinc, aluminum and other light metal alloys are not sufficiently protected.
- The dissolution of deposits and mill scales is not affected by LITHSOLVENT EB.
- It is particularly remarkable that LITHSOLVENT EB is able to reduce the diffusion of hydrogen into the steel to a minimum thus avoiding the acid embrittlement (compare DRAHT, 7.35/38. 1956).
- Addition and Dosing
- In general the dosing rate amounts to 2.5 kg LITHSOLVENT EB /m3 diluted cleaning or pickling acid (3-10 %) considering a proportion volume/surface of max. 1 : 50, i.e. 50 m² of surface should be touched by at least 1 m³ solution volume. In case of larger surfaces the inhibitor quantity must be proportionally increased and amounts e.g. at a proportion of 1 : 100 to approx. 5 kg LITHSOLVENT EB/m³.
- Prior to the additon to the diluted acid LITHSOLVENT EB has to be stirred up into the water in the ratio 1:2 and well agitated. The inhibitor should not be added into the concentrated acid as otherwise lumps are being formed.
- The duration of action of the inhibited acid on the materials should not exceed 6 hours, at boiling temperature not 2 hours.
- After cleaning the plant and apparatus should be carefully rinsed with water until they are free from acid.
- Areas of Application
Evaporators, steam boilers, heat exchangers, piping systems and all kinds of heat engineering equipment.
- Coverings
Inorganic scale such as calcium carbonate, calcium oxalate, silicates, occasionally phosphates, aconates, citrates, depending on water use, also sulfates or organic coatings.
- Examples / Best Practice
Universal powder inhibitor suitable for protection of all metals.
- Remove / Protect Coatings
Protection of metallic materials during chemical cleaning or pickling with hydrochloric acid and its mixtures with hydrofluoric acid at temperatures up to 100°C.
