DESIGN SAFETY FLOW SHEET | CAD Design of Ammonium Sulphate Saturator

The safety of a chemical plant is structured in the above way to find the faults and design the process with foolproof, for the execution of the project it is taken to the drawing board and reviewed to find the safety interlock system of the process.

CAD Design of Ammonium Sulphate Saturator



Coke oven gas after primer cooling and purification from tar & naphthalene In PCG & esp are delivered under the temperature of 50- 60 through the pre-heater to the saturator. The heating of C.O. gas enters the pre-heaters ensures the normal water balance in saturators.

The C.O. enters the saturator by the main gas inlet and passes through the bubbler hood which consists of 20 radically the bubbler hood which consists of 20 racially positioned elements of shape. Bubbling through mother liquor C.O. gas passes an element that sets from only one side of the bubbling that sets up an intensive organized movement of the mother liquor over the circumstances towards the periphery.

Mother liquor acidity of the saturator bath is automatically maintained within 4-5% with the help of the pH- meter station & control valve and adding the concentrated sulphuric acid to the saturator and by constant feeding 6-8% acidified mother liquor solution from the liquor tanks.

To ensure a good reaction which is C.O .gas with sulphuric acid which is in the mother liquor, the bubbler hood is submerged in the mother liquor by 190-250 mm. ammonium bisulphate is firmed by reaction

NH3 + H2SO4 → (NH4)2SO4

This ammonia bisulphate is converted into ammonium sulphate (NH4)2SO4 Heat is given off while forming ammonium sulphate from the saturator, the gas flows into the direction to the bottom gas main leading to the F.G.C., to the benzol section and then to consumers.

From the acid trap, the gas in the acid trap is continuously from gas in the acid trap is continuously delivered to the circulating pan through the pipe, the end of which is submerged into the seal pot to prevent forming of acid-neutral zones in the saturator bath, to achieve a better condition of crystals growth and to reduce gas /ammonia losses, it is necessary to keep the mother liquor inside the saturation under through mixing.

The mother liquor is mixed by the C.O gas passing through the bubbler hood and bubbling in the upper layer of the mother liquor and hence settling this into a circular motion. Nitrogen which is admitted to provide vertical motion of the mother liquor that ensures favourable conditions for the crystal growth:

The circulating is pumping which is pumping it from the circulating pan to the conical part of the saturator.
