Plants and capacities

TERPINEOL DIVISION
“GRILL AND GROSMANN’ RECTIFICATION COLUMN’ Plant
    It is designed for vacuum rectification of sulfate and gum turpentine into pure terpenes - alpha-pinene (left- and right- rotation), beta-pinene, camphene, delta-3-carene, limonene, terpinolene, pine turpentine and perfumery terpineol. Pure terpenes are used in perfumery and cosmetics industry.

‘CRUDE TERPINEOL’ Plant 
   This plant is applied for obtaining of crude terpineol. The crude terpineol is produced from sulfate and gum turpentine under classical technology - through hydration in an acid environment and following de-hydration of crystals in a light acid environment. The obtained crude terpineol is used in vacuum rectification column ‘Grill and Grosmann’ for production of perfumery terpineol.
 
‘CATALYSTS’ Plant.
    In this plant are produced different kinds of catalysts on the basis of PFSK (para-phenolsulfonic acid), FSK (phenol-sulfonic acid) and KSK (kxylene-sulfonic acid).
Catalysts are used to harden furan resins, which are used as binding material in production of cold hardening foundry forms and hearts.
DIVSION AND TALL OIL SICCATIVES

‘FURAN RESIN’ Plant
    Two types of resins are produced on the basis of poly condensation under atmospheric pressure and vacuum:  
  1.  Furan resins:  they are used as binding substances in the production of cold-hardening shaping molding admixtures in the production of steel and cast-iron
  2. Phenol-formaldehyde resins: these resins are used in the production of friction products, such as cover plates for car brakes and etc.
‘TALL OIL SICCATIVES’ Plant 
    In this plant are produced different kinds of siccatives, as: lead, manganese, cobalt. The same are used in paints and varnishes industry as a component in varnishes, paints and primers.

 
‘GUM RESIN’ Plant
    This plant processes liquid and dry gum (pine) resin through distillation with water steam until gum rosin and gum turpentine are obtained. The gum rosin and gum turpentine are applied in paints and varnishes, perfumery and cosmetics and pharmaceutical industry.     

  
DIVISION TALL AND PAPER SIZE

‘TALL OIL’ Plant
     Tall Oil Plant is a deep vacuum rectification plant, which automatically follows the technological process. It has been constructed by the Swedish company ‘Linderpatent’ to comply with the modern technological requirements and has been periodically reconstructed and modernized.   
The Tall Oil Plant is designed for processing of tall oil - a by-product in the production of sulfate cellulose from wood, as well as, of fatty acids from different kinds of vegetable oils – sunflower, rape, nut, soy-been, cotton and etc.
Through vacuum rectification of tall oil the following products can obtained: tall oil rosin, tall oil fatty acids, light oil and pech.
Through vacuum rectification of fatty acids from vegetable oils distilled fatty acids and pech are obtained.
Tall Oil Rosin and Tall and Vegetable Fatty Acids are used in paints and varnishes industry.

 
‘PAPER SIZE’ Plant
    Powdery and liquid paper size are produced at this plant. The main raw materials in use are tall oil or gum rosin and sodium hydroxide. The size is used in cellulose-paper industry for paper sizing.

  

PAPER DIVISION

PLANT FOR PRODUCTION OF CARDBOARD
    It is a machine, composed of a system of smooth and relief shafts, which are heated with a water steam with a purpose – gluing of two layers fluting with a liquid glass. In this plant is produced two-layers corrugated cardboard.

  
PLANT FOR PRODUCTION OF CARDBOARD BOXES
    The plant is a system of right-size machines, band-saw machines, rotation-rasps, wire-saw machines, pneumatic press and packing machine of the waste product.
In this plant are produced cardboard boxes of three- and five-layers corrugated cardboard.
  
DIVISION ALKYD AND SOLVENTS

‘ALKYD RESIN’ Plant
    In this plant are produced different kinds of modified alkyd, synthetic and polyester resins. The resins are the basis for production of alkyd paints, varnishes and primers.

 
‘SOLVENTS’ Plant    
    This plant is designed for obtaining of different of solvents, as:
    The same are used for dilution of alkyd, nitro-cellulose and other kinds of paints.
 
DIVISION PAINTS , VARNISHES AND CONSUMER CHEMICAL PRODUCTS
