Irani

Resins

Celulose Irani produces resins from the natural extraction of pine according to environmental management standards for the manufacture of rosin and turpentine, these are very versatile raw materials with applications in products such as varnishes, adhesives and paints and enamels.

The Resins Unit is located in Balneário Pinhal in Rio Grande do Sul and has the capacity to produce 50 tons of Rosin per and 15 tons of Turpentine per day.

The main foreign markets for rosin and turpentine that are served by IRANI are Argentina, Chile, USA, Netherlands, Spain, Portugal, Mexico, Germany, Belgium and France. The main Brazilian market is located in Rio Grande do Sul

    About our products
The resin extraction process in IRANI is performed on selected trees that need to be about 12 years of age and be at least 18 cm in diameter.

The resin extraction process consists of the extraction of gum resin from living trees of the Pinus genus. It is considered by many as a way to anticipate revenues from forests that are deployed for purposes other than the production of gum resin. In addition, it generates direct jobs and contributes to the stabilization of the man in the countryside.

The gum resin obtained by exudation of pine trees is a mixture of long chain hydrocarbons, consisting of several resin acids, with the main one, abietic acid, which after distillation, becomes a solid part, called rosin and the volatile part, consisting of cyclic aromatic hydrocarbons, called turpentine.

In IRANI, the products obtained from this process are sold for making varnishes, paints, soaps, glues, adhesives, polishes, disinfectants, perfumes and insulation that currently meet, mostly, the demands of foreign markets.

Rosin: printing inks, paper glue, adhesives, emulsifiers, rubber and other sectors, including cosmetics, soaps, detergents and the food industry such as chewing gum.

Turpentine: because of being composed of cyclic aromatic turpentine is used as a raw material for the processing of many products such as; terpenila acetate, isobornyl, terpineol, which are used in perfumery and the fragrance industry. The Pine Disinfectants that have a germicidal action use this product in their formulation, the pine oil is derived from the processing of turpentine. In the fine chemicals industry, turpentine is used for vitamins, components of natural insecticides, resins for specialty adhesives, among others. Its use extends as special paint thinner as well as in pharmaceuticals.

Markets: the major foreign markets for rosin and turpentine are: Argentina, Germany, Portugal, Holland, France, Spain and the United States.

The resin extraction process began in Brazil in the 1970´s, a period when the country was importing the product. In 1989, the situation reversed, and now those who bought it, now sell it.

Currently, we are the second largest world producer of gum rosin, just ahead of China. In the country, approximately 100 000 tons of resin per year are produced, representing a financial turnover of 25 million dollars.

The Pinus gum resin has been used since ancient Egypt, for religious purposes and for the mummification of bodies. It was also widely used, since the colonial American times is shipbuilding, with the goal of caulking pieces of wood, used in the British Royal Navy boats.

Phoenician and British sailors from the Victorian era, regardless of the time between, they used the gum resin, in a way similar to caulking (sealing) in the waterproofing of the sailboats, and the British responsible for the collective name of naval stores used in English speaking countries, even today, to denote the derivatives of gum resin.

The name Turpentine is of Greek origin and was given to the resin obtained from Pistaciaterebinthius of the family of anarcadiaceae.

The use of turpentine is old, and recorded from the existence of pictures and quotes of Indians in Mexico who extracted turpentine from the resin of trees in barrels on fire directly in the Pre-Columbian era.

In the 19th century, in North America, turpentine was also used as fuel for lamps, in addition to generating light, it issued a pleasant aroma into the environment.

The first cases of separation of rosin and turpentine gum resin were made in pot stills on an open fire. However, much of the volatile product was lost into the atmosphere, in addition to obtaining a low-quality turpentine by the existence of impurities by products of pyrolysis (decomposition by heat).

The need for rosin as a raw material for various commercial products like paper, led to improvements in technology of fractionation of these two compounds in the crude resin. Consequently, the qualitative aspects of turpentine have also been improved by replacing the intermittent batch distillation by the continuous columns without filling and subsequently by the distillation in autoclave.

In IRANI, the separation of rosin gum of the turpentine in the resin gum is done by the following method;

1 –The resin is received in drums from the forest by truck.

2 –After the reception the product is dumped into the storage tank (barge).

3 –Resin Filtration: In this stage, the resin is heated to 100 ° C with the addition of turpentine to facilitate the process. Then, two filtrations are carried out - one by a coarse filter removing the larger impurities and a thinner filter, through a filter press where all impurities are retained.

4 –Decanting the resin: the resin is left in settling ponds for 18 hours where the water separation occurs. The disposed of wastewater is processed in the Effluent Treatment Station, and reused.

5- Distillation resin: Once decanted, the solution is washed, filtered, bleached and heated it is pumped to the top of the distillation column. During this stage, the turpentine is separated from the rosin through evaporation.

6 –Filling: After the complete extraction of the turpentine, the rosin is poured into metal drums or paper bags. Then it is cooled and stored in a warehouse. Turpentine is pumped to the tank farm and sold in bulk.

This process is the one that is more used currently, because of having more technological advances enabling improvements in the quality of both the production of turpentine and rosin

IRANI produces resins from selected Pínus according to the environmental management standards for the manufacture of rosin and turpentine, raw materials of great versatility of applications used in products such as varnishes, paints, adhesives and enamels.

Rosin: Rosin is a solid transparent yellow color, produced from the secretions of the resinous pine. It is composed of abietic acid (main component) and used for applications such as glues, adhesives, soaps, enamels, electrical insulators, gum, wax, and expectorants.

Turpentine: In IRANI, the type of turpentine is obtained from the gum resin. Turpentine is a transparent liquid with a characteristic odor and bitter taste. It is used as a solvent in paint and varnish manufacture of dyes, waxes, disinfectants (pine oil), camphor, soap, grease,
