Presence in South America

Unipar has two factories in Brazil, the plants of Cubatão and Santo André, in San Pablo, and a factory in Argentina, in the city of Bahía Blanca. With safety, respect for the environment and following strict quality standards, the three facilities are responsible for the production of 766,000 tons/year of Caustic Soda, 680,000 tons/year of Chlorine and 540,000 tons/year of PVC, among other products widely used in our industry.

CUBATÃO

The Cubatão complex is one of the most advanced plants producing Chlorine and Soda in the world. Located in the local industrial park, the factory is close to the port of Santos and the Anchieta-Imigrantes road system and contains a Protected Natural Area (RPPN) covering 7,000 square meters, recognized by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). The RPPN is situated inside a 650,000 square-meter green space, which is seven times the size of the company’s industrial area. We have shown that it is possible to achieve a balance between environmental preservation and our operations.

SANTO ANDRÉ

Located in the region in Mercosur with the highest consumption of PVC, and close to the first petrochemical hub in Brazil, Capuava, our facilities in Santo André provide strategic supplies for the company’s production.

Situated near the port of Santos, the plant receives raw materials and delivers products to clients by sea. The region offers good train and road connections as well as an important source of electrical energy, which helps the plant produce chemistry with operational excellence.

BAHÍA BLANCA

With an area of 1,050,000 square meters and an unbeatable location, the Unipar complex in Bahía Blanca, province of Buenos Aires, Argentina, provides all the necessary raw material for our production -gas, electricity and salt- in addition to easy access by road, train or boat to the different markets in the region.

Other available resources include deep-water ports of entry and exit that facilitate exports, and human resources, i.e. working people, that are highly skilled according to the local educational institutions.

Sodium Hypochlorite Reactor

 Hypochlorite is produced by a reaction between gaseous Chlorine and a Caustic soda solution being cooled down.

17

EDC Reactor

EDC (Dichloroethane) is obtained through a reaction between liquid chlorine and ethylene (inserted through a tube) and it is purified by distillation.


15

Hydrochloric Acid Reaction Furnace

Hydrochloric acid is produced by a controlled combustion reaction of Chlorine and hydrogen, followed by absorption in treated water.

13

Evaporation

Caustic soda is produced by electrolysis and reduced through the evaporation process.

14

Cooling

 Then, the Soda is cooled down and stored in tanks, before being shipped.

Phases

(8) Cooling Chlorine

(9) Chlorine Withdrawal

(10) Chlorine Compression

(8) The produced gaseous chlorine is cooled down, (9) dried out and (10) compressed. After being compressed, it turns into a liquid state at low temperature.


Stages

(3) Treatment

(4) Filtration

(5) Control

(3) The PICKLE is about eliminating foreign bodies; it is filtered (4) and undergoes a strict control (5) before feeding the ELECTROLYTIC CELLS.

(3) Tratamiento

(4) Filtración

(5) Control

(3) La salmuera se trata para eliminar impurezas, se filtra (4) y pasa por un estricto control (5) para alimentar las CÉLULAS ELECTROLÍTICAS.

Start

If there are salt (sodium chloride) and water in stock, you need to supply our transformers with electricity.

Etapas


(11) Licuefacción de Cloro

(12) Almacenamiento de Cloro

(11) El cloro en esta forma se almacena en tanques (12) donde se carga en camiones especiales

Sala de Celdas

La ELECTRÓLISIS tiene lugar en la celda. Y así, la energía eléctrica actúa sobre la salmuera y la transforma en SODA CÁUSTICA, CLORO E HIDRÓGENO.

Evaporação

A Soda Cáustica é produzida na eletrólise e concentrada pelo processo de evaporação.

Cell Room

The ELECTROLYSIS takes place in the cell. This way, electric energy acts on the brine and transforms it into CAUSTIC SODA, CHLORINE AND HYDROGEN.

Etapas

(3) Tratamento

(4) Filtração

(5) Controle

(3) A SALMOURA é tratada para eliminar impurezas, filtrada (4) e passa sob um rigoroso controle (5) para alimentar as CÉLULAS ELETROLÍTICAS.

Pickle

Next, prepare the PICKLE obtained from dissolving the salt in the water to use afterwards in the ELECTROLYSIS.
