OPEN FACTORY IS...

During the last three decades, we have worked to develop the five core values of our program.

TRANSPARENCY

We believe that, in order to promote real transparency and generate long-lasting bonds with our partners, suppliers, clients and the local community, it is necessary to really open our doors. For this reason, the Open Factory Program is open to all visitors, seven days a week.

 

During the visit, which is completely free, visitors can walk around our factories and circulate safely under the guidance of those who know Unipar better than anyone else: our collaborators. Nowadays, the visits are guided by active and retired collaborators, many of whom worked in our factories for over 20 years.

THE COMMUNITY

One of the main goals of the Open Factory Program is to build a relationship with those who are closer to our factories. For this purpose, we have the Community Consultative Council (CCC), which is made up of spokespersons of the community living in the area round our plants located in Brazil and Argentina. The group discusses matters related to Health, Safety and the Environment, and it participates actively in the creation and development of Unipar’s social projects.

EDUCATION

One of the main participants of the Open Factory Program are all-level students interested in the areas of chemistry and engineering. Getting to know an operating factory is essential to help prepare those students for the market. The educational characteristic of the program has another important aspect: showing how Unipar values safety, health and environmental concerns. We believe in the importance of showing those young people that it is possible to create a solid, profitable company aligned with those values.

THE ENVIRONMENT

Producing in harmony with nature implies constant dedication across all Unipar’s operations. In order to guarantee the success of this mission, the company boasts an Integrated Management System that is regularly audited by external entities pursuant to ISO 9001, ISO 14001 and the Responsible Care® Program standards. The Cubatão factory led the way into environmental matters in Brazil.

Back in the 1970’s, it started an environmental management program and created Parque da Lagoa, a preservation area that was later on, in 1992, included in the category of Natural Heritage Private Reserve (RPPN, for its acronym in Portuguese) by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). In the 1980’s, it created an Internal Environmental Commission and, in 1997, it was recognized as a Preserver of Wildlife. Nowadays, authorizations for the RPPN and the Preserver are granted and controlled by the Secretariat for the Environment of the State of São Paulo – Wildlife Center.

SAFETY AND HEALTH

The commitment to excellence in terms of safety and health is well present in Unipar’s operations, from the production process to the attention paid to the transportation of its products and the concern about the health of its collaborators and the communities that live near the factories.

 

The company provides trainings and courses that, together with the collaborators’ commitment, are paramount for having a healthy and safe work environment.

 

Therefore, any irregularity that may be identified is rapidly informed and isolated, which ensures risks are kept under control. Moreover, all relevant cases are analyzed and corrected in order to avoid recurrence.

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.
