Description
Насто щее изобретение относитс к области очистки промышленных газов. Известна очистка последних от H2S фенол тным раствором, содержащим в значительном количестве свободный фенол (так называемый фенольно-фенол тный раствор ).The present invention relates to the field of purification of industrial gases. The latter is known to be purified from H2S with a phenolic solution containing free phenol in a significant amount (the so-called phenolic-phenolic solution).
Применение растворов фенол та натри дл очистки промышленных газов, содержащих относительно низкий процент сероводорода и значительные количества углекислоты (например , дл очистки коксового газа), затруднено вследствие накапливани в поглотительном растворе карбоната натри , разложение которого мри обычной регенерации (кип чении) происходит лишь в незначительно.й степени и крайне медленно. Вследствие этого отработанный раствор необходимо периодически подвергать каустификации известью, что затру хн ет и осложн ет использование фе:нол тного метода дл очистки названных газов, содержащих одновременно с сероводородом углекислоту .The use of phenol sodium solutions for the purification of industrial gases containing a relatively low percentage of hydrogen sulfide and significant amounts of carbon dioxide (for example, for purifying coke oven gas) is difficult due to the accumulation of sodium carbonate in the absorption solution, the decomposition of which occurs only slightly. degree and extremely slowly. As a result, the spent solution must be periodically caustified with lime, which will zate and complicate the use of the ferrite method for purifying the named gases containing carbon dioxide simultaneously with hydrogen sulfide.
Процесс регенерации отработанного раствора предлагаетс производить не обычным кип чением при нормальном давлении, а нагревом его до температуры 120-135° при соответствующем давлении в 2-3 ат с избыточным количеством фенола. В этих услови х за короткий промежуток времени, вследствие значительного повышени константы электролитической диссоциации фенола, удаетс достигнуть выделени сероводорода (с любым начальным содержанием его) из отработанного поглотительного раствора на 85 - 95%, выделени углекислоты и, следовательно , разложени образовавшегос карбоната натри на 8С- 85%.It is proposed to regenerate the spent solution not by ordinary boiling at normal pressure, but by heating it to a temperature of 120-135 ° at a corresponding pressure of 2-3 atm with an excess amount of phenol. Under these conditions, in a short period of time, due to a significant increase in the electrolytic dissociation constant of phenol, it is possible to achieve release of hydrogen sulfide (with any initial content) from the spent absorption solution by 85-95%, carbon dioxide release and, therefore, decomposition of sodium carbonate formed in 8C - 85%.
Количество фенола в растворе должно соответствовать от 0,5 до I избыточного эквивалента. Присутствие последнего в растворе практически не оказывает вли ни на поглотительную способность раствора и на степень очистки газа от сероводорода (по сравнению с чистым раствором фенол та натри ).The amount of phenol in the solution should correspond to 0.5 to 1 excess equivalent. The presence of the latter in the solution has practically no effect on the absorption capacity of the solution and on the degree of gas purification from hydrogen sulfide (as compared with the pure solution of phenol and sodium).
