Abstract
Inventia se refera la un procedeu de preparare a metanolului si consta în aceea ca gazul de sinteza de obtinere prin amestecul a doua fluxuri continand CO, CO2 si H2 si gaze inerte, primul flux fiind obtinut pron reformarea unui amestec de gaz natural cu abur si gaz de purja de la bucla de sinteza la care se poate adauga CO2 file în fata reformerului fie în gazul racit de reformer cel de al doilea flux fiind obtinut : prin reformarea autoterma într-un reactor cu pat fix si catalizator a gazului natural cu abur, oxigen si CO2 sau prin reformarea cu 02, abur, si CO2 a gazelor reziduale de la obtinerea acetilenei sau altor produse reziduale de la distilarea titeiului gazul de purja de la bucla de sinteza a metanolului de joasa presiune este trecut într-un al doilea reformer tubular unde împreuna cu CO2 sau metan +CO+ abir constitue materia prima pentru obtinerea unui gaz de sinteza stoichiometric ce se foloseste într-o a doua bucla de sinteza la o presiune mai ridicata.The invention relates to a process for the preparation of methanol and consists in that the synthesis gas obtained by mixing two streams containing CO, CO2 and H2 and inert gases, the first stream being obtained by reforming a mixture of natural gas with steam and gas to purge from the synthesis loop to which CO2 can be added in front of the reformer either in reformer cooled gas; the second flow is obtained: by self-reforming in a fixed bed reactor and natural gas catalyst with steam, oxygen and CO2 or by reforming the waste gas from the acetylene or other residual products from the distillation of crude oil with the O2, steam and CO2 from the distillation of crude oil, the purge gas from the low pressure methanol synthesis loop is passed to a second tubular reformer where together with CO2 or methane + CO + abir are the raw material for obtaining a stoichiometric synthesis gas to be used in a second synthesis loop at a higher pressure.
