Sulphuric Acid

Process Equipment › Acid Distributors

SULPHURIC ACID / ACID DISTRIBUTORS

For effective gas / sulphuric acid contact in the ceramic packing bed in a Drying Tower or Absorbing Tower, the acid must be distributed evenly and consistently over the cross sectional area inside the tower. The type and volume of the packing is...

Sulphuric Acid

Process Equipment › Tower Packings

SULPHURIC ACID / CERAMIC TOWER PACKINGS

In a Sulphuric Acid plant contact section there are Drying and Absorbtion Towers, which are fitted with and acid distribution device, which sprays or flows Sulphuric Acid downwards into a bed of (usually) random packings which allow the upward flowing gas to...

Sulphuric Acid

Process Equipment › Ceramic Dome

SULPHURIC ACID / CERAMIC PACKING SUPPORT DOME

In a Sulphuric Acid plant contact section there are Drying and Absorption Towers, which are fitted with an acid distribution device, which sprays or flows Sulphuric Acid downwards into a bed of (usually) random packings (different types and sizes of saddles...

Nitrogen Fertilisers

Filter › AN Neutraliser

NITROGEN FERTILISERS / AMMONIUM NITRATE – NEUTRALISER & EVAPORATOR

Ammonia and Nitric Acid are fed to the Neutraliser, which can be operating under pressure, under vacuum or at atmospheric pressure. There is a high exothermic reaction which produces NH4NO3 and steam.
Ammonium Nitrate solution is then fed to...

Nitrogen Fertilisers

Filter › AN Prilling

NITROGEN FERTILISERS / AMMONIUM NITRATE – PRILLING TOWER

Concentrated Ammonium Nitrate (NH4NO3) solution comes from the Evaporator and is sprayed downwards from the top of the Prilling Tower. The inlet air draft rising inside the Prilling Tower cools the falling, sprayed solution, which then forms into solid...

Nitrogen Fertilisers

Filter › Urea Evaporator

NITROGEN FERTILISERS / UREA –EVAPORATOR

Urea is formed in the liquid phase following different reactions, in one of 3 types of process : Once Through ; Partial Recycle ; Total Recycle.
Liquid NH3 is mixed with CO2 gas and any recycled Carbamate under high pressure (3200 psi ),...

Nitrogen Fertilisers

Filter › Urea Prilling Tower

NITROGEN FERTILISERS / UREA – PRILLING TOWER

Concentrated Urea solution comes from the Evaporator and is sprayed downwards from the top of the Prilling Tower. The inlet air draft rising inside the Prilling Tower cools the falling, sprayed solution, which then forms into solid ‘prills’. The prills then...

Nitrogen Fertilisers

Filter › NPK Spherodiser

NITROGEN FERTILISERS / NPK PLANT ACIDULATION & SPHERODISER EMISSIONS

NPK is a fertiliser where 27% of the product is N, P or K, made up of 3, 12 and 12%, respectively. Among the filters used in an NPK plant are those for Acidulation and Ammoniation duty, treating the...

Nitrogen Fertilisers

Filter › HNO4 Inlet Air

NITRIC ACID / INLET AIR AND NH3 FILTERS

NH3 is oxidised with air on catalyst to form NO at high temperature ( 700 – 1000°C ), in a quick exothermic reaction. After cooling, NO is oxidised by excess air to give NO2. This oxidation continues into the absorbtion...
