Description
Изобретение относится к абсорбционным методам очистки газов от кислых примесей и может найти применение в газовой и нефтехимической отраслях промышленности. 3 The invention relates to absorption methods for the purification of gases from acidic impurities and may find application in the gas and petrochemical industries. 3
