SULPHURIC ACID: OVERUSED, CONTAMINATED, USED, classified as waste

Change in the Company's business profile, which is related to the sale, regeneration, processing, and recovery of sulphuric acid from external suppliers. Thanks to its unique technology, the Company can close the circulation of substances in various production processes, thus offering an innovative solution in line with the idea of the Circular Economy and Environmental Protection.

The recovery process is conducted in several stages:
- Combustion of the raw material in a furnace, complete oxidation of the raw material to CO2 and H2O, with decomposition of sulphur to SO2,
- Recovery of combustion heat in the boiler - transfer of exhaust heat to produce steam,
- Dedusting of process gas – removal of solid impurities in the electrostatic precipitator,
- Two-stage catalytic conversion of sulphur dioxide to sulphur trioxide in a reactor,
- Condensing sulphuric acid from the process gas in the condenser.

RECOVERY OF SULPHURIC ACID

We focus on professional, most advanced, and modern methods enabling the recovery, regeneration, and processing of sulphuric acid. Our goal is to enable companies to conduct business in an environmentally safe manner while minimizing emissions of pollutants into the atmosphere. We know how to achieve the desired results in this field, supporting the implementation of the company's business goals and strategy.

SULPHURIC ACID PROCESSING

We have many years of experience in supporting clients in caring for the environment and complying with the regulations in force in this area. For example, through the processing of sulphuric acid, which is possible thanks to the use of appropriate installations and technology.
