Abstract

Karbamido gavimas iš amoniako ir anglies dioksidosintezės zonoje suformuojant karbamido lydalo srautą, kurį apdoroja dviejose distiliavimo pakopose,atskiria karbamido tirpalus ir dujų srautus, po kondensacijos ir absorbcijos sukuria anglies amoniodruskų tirpalus. Pirmoje pakopoje lydalas iš kolonos paduodamas į pirmą distiliavimo zoną, kur lydalo skaidymą atlieka plėveliniame šilumokaityje anglies dioksido sraute. Dujinę fazę pirmoje distiliavimo pakopoje naudoja šilumos mainams su karbamidolydalu antroje distiliavimo pakopoje. Įranga turi pirmos distiliavimo pakopos koloną, kurios viršus sujungtas su rekuperaciniu šilumokaičiu antros distiliavimo pakopos antroje zonoje, o kolonos apačiasujungta su plėveliniu šilumokaičiu, aprūpintu anglies dioksido tiekimu. Distiliavimo kolona ir plėvelinis šilumokaitis pirmoje distiliavimo pakopojesurišti su rekuperaciniu šilumokaičiu antros distiliavimo pakopos pirmoje zonoje. Pirmoji ir antroji distiliavimo pakopos turi įrenginius distiliavimo dujų kondensavimui ir absorbcijai. Antroje distiliavimo pakopoje po separatorių pastatytas rekuperacinis šilumokaitis, antros distiliavimo pakopos dujų garinimui ir sukaitinimui, sujungtas su antrosdistiliavimo pakopos pirmos zonos šilumokaičiu - rekuperatoriumi.
