Ammonia (NH3) is one of the most important products in chemical industry used as a feedstock for nitric acid, ammonium salts, nitrates (nitric acid salts), nitrogen fertilizers, explosives, paints and pharmaceutical products production.
Packing and transportation: tank-cars, tankers, other packing provided under a contract.
Comparing to usual sulphate, basic aluminium sulphate contains no free acid and has increased aluminium/sulphate ratio. Treated water is acidified less and better coagulated. Besides, aluminium sulphate makes smaller impact on cellulose. When using base aluminium sulphate for water treatment decreased amount of sulphate leads to smaller amounts of plaster residue.
Iron content may be limited according to customer's requirements
Packing: product has weak acidic properties, therefore should be shipped in stainless steel or acid resistant tank-cars or tankers. May be stored in plastic (PE, PP) containers. Available in 60 t tank-cars, 14 t tankers, 60 l plastic bottles or other suitable containers provided by client.
Formaldehyde solution (CH2O water solution - formalin) is used as raw material for organic combination, formaldehyde resin, plastic production, organic material synthesis, disinfection, and anatomic preparation conservation, as fungicide. Formaldehyde solution is toxic, flammable, explosive liquid. It's vapour together with air form explosive compounds. Working with formaldehyde solution requires safety rule following.
Packing: transported in aluminium and stainless steel rail tanks and tank-cars, barrels, polyethylene cans or barrels. After approbation can be transported in carbon steel rail tanks, tank-cars and vessels. Transported following cargo transport (RID/ADR) regulations. No more than 95 % of tank volume is filled; tank must be sealed.
Nowadays, urea and melamine–urea formaldehyde resins are still most commonly used in the production of particle boards, wood-based panels, in furniture manufacturing and interior decorating, as well in furniture industry for gluing various wooden parts, in casting industry and for other household purposes.
According to (EC) No. 1272/2008, urea formaldehyde and melamine urea formaldehyde resins are not classified as dangerous (the mass fraction of free formaldehyde in the resins is less than 0.1%).
Urea formaldehyde resins are produced under the following brands: KF-FE, KF-MEC07, KF-MEC13 and KF-MEC15. The first two letters „KF” stand for „urea formaldehyde”, the third, fourth and fifth letters and numbers after the dash stand for the corresponding brand. The partition into brands depends on the different production technology and the rates of raw materials are used.
KF-MEC07, KF-MEC13 and KF-MEC15 are used for wood particleboard production. Articles containing KF-MEC07, KF-MEC13 and KF-MEC15 meet E1 class formaldehyde emission (HN 105) requirements.
KF-FE are used for plywood production, mould pressing, thermal insulation material and wood particleboard production for gluing flexible, curved plywood and wooden parts. Articles containing KF-FE meet E1 class formaldehyde emission (HN 105) requirements.
Melamine urea formaldehyde resins are produced under the following brands: MKF-F4I4, MKF-F4I5 and MKF-P. The first three letters „MKF“ mean „melamine urea formaldehyde“, and the fourth and fifth letters and numbers (F4I4, F4I5, P) after the hyphen mean the corresponding brand. The partition into brands depends on the different production technology and the rates of raw materials are used.
MKF-F4I4, MKF-F4I5 and MKF-P brand resins are used for the production of wood chipboards, which correspond to class P2 according to LST EN 312. MKF-P brand resin is used in the production of wooden pallets (including EPAL EURO pallets).
Using MKF-F4I4 and MKF-F4I5 brand resins for the production of wood chipboards, it is possible to achieve 4 mg/100 g of dry board (EN 12460-5) and (0.3÷0.4) mg/l (JIS A 1460) formaldehyde emission.
Aqueous urea solutions AUS 40, AUS 32 and AUS 20 are NOx reducing agents.
Aqueous urea solution AUS 32 reduces nitrogen oxide emission from auto exhaust system. The solution is injected to diesel engine exhaust systems before selective reduction catalyst, consequently due to the solution reaction with nitrogen oxide gasses emissions are converted to water vapour and nitrogen. This technology optimises engine performance by reducing particle emission and maximizing fuel energy generation. Another significant effect of the process is reduced fuel consumption (on average 5 %).
Aqueous urea solution AUS 40 reduces nitrogen oxide emission from vessel or diesel engine exhaust system. The solution is injected to diesel engine exhaust system before selective reduction catalyst, consequently due to the solution reaction with nitrogen oxide gasses emissions are converted to water vapour and nitrogen.
Aqueous urea solution AUS 20 is used for removal of NOx formed from smoke stumps spreading/spraying in the incineration system, moreover as anti coniferous diseases (root sponges) spread.
Nitric acid is one of basic products in chemical industry. It is used as raw material for fertilizer, sulphuric and concentrated nitric acid production; for metal etching processes. Nitric acid salts are used in agriculture, most of all in the form of ammonium nitrate produced by neutralizing nitric acid with ammonia. It is also used for production of complex fertilizers when natural phosphates are dissoluted in nitric acid.
AB "Achema" produces nitric acid with a concentration of 56 - 59 % by absorbing nitrogen oxides with water.
Packing: non concentrated nitric acid is poured into railway tank wagons, road tankers, in accordance with the applicable regulations, ensuring safe transportation and storage.
