Flexographic printing



Information and advertisement take special place in modern world most needed is image information and advertisement. In this case increasing of printing industry production capacity is occurring: different image printing techniques on different carriers.

For example:

  • Magazines;
  • Leaflets;
  • Posters;
  • Advertising booklet;
  • Banners;
  • Packing;
  • Other;

But high necessity of print industry run into trouble – emissions to atmosphere and working area air big amount of different organic solvents, many of which are very dangerous for human health and environment.

Any printing method uses volatile solvent-based paint. Every of this compound is polluter of working area air and technological emissions.

  • methyl ethyl ketone,
  • sterol,
  • acetone,
  • methyl isobutyl ketone,
  • N-butylacetate,
  • toluene,
  • xylene,
  • ethylbenzene,
  • ethyl acetate,
  • ethanol,
  • methanol,
  • methoxypropanol,
  • propanol,
  • …..

Organic fumes and gases are harmful and hard-to-remove from air. In paint and varnish industry ventilating emissions concentration of solvents reach 5000mg/m3 of air.

Solvents fumes can be removed from a working zone and fabrication facilities using exhaust ventilation and release into the atmosphere. But in that case two main difficulties appear.

  • Necessity to heat and fan incoming air in rooms
  • Government limitation to release of harmful substances into atmosphere.

So many item manufacturers faced with the task to clean ventilating emissions and working area from solvents fumes.

Nowadays available several technologies of cleaning air from organic solvents fumes: absorbing (activated carbon), scrubbers (liquid absorption), biological cleaning, reburning, catalytic, photocatalytic and gas-discharge-catalytic. All these technologies have positive and negative sides.

”Ecopromika” company Ltd worked out and produce special equipment complex for cleaning air from solvents fumes on paint and varnish manufacturing plants – “Gasconvertor “Yatagan”. For today these type of equipment has the best “cost-quality” and “efficiency-dimensions” performance, practically doesn’t have replaceable parts, doesn’t need wastes utilization and has lowest operation cost. “Gasconvertor “Yatagan” installations efficiency of cleaning air from solvents confirmed by many tests on a stand in laboratory environment and operating enterprises.

Rest on field experience of “Gasconvertor “Yatagan” on different enterprises we recommend:

  • To clean ventilating emissions from solvents fumes use “Gasconvertor “Yatagan X,X – 1000/4000” installations;
  • To clean air in recycling ventilating systems use “Gasconvertor “Yatagan X,X -200R” or “Gasconvertor “Yatagan X,X -2000R”.

“Gasconvertor “Yatagan” installations to clean air from solvents fumes used on enterprises like part of ventilating systems (combined extract and input ventilation, recycling ventilation), or like separate local air cleaner.
