Abstract

PURPOSE:To remove H2S and SO2 in the simple treatment by sending both a gas contg. H2S and a gas contg. SO2 simultaneously and continuously into the pressurized water free form an additive and allowing both to perform the Claus reaction. CONSTITUTION:Both a gas contg. H2S and a gas contg. SO2 are sent into a reactor 1 charged with water free from an additive through the lines 2, 3 and the soln. in bubbled in the pressurization. The Claus reaction is made active together with passage of time and elemental sulfur is produced and made slurry. The slurry of sulfur is sent to a separator 5 through a line 4 to separate it into water and sulfur and sulfur is discharged through a line 6 and water after the separation is circulated to the reactor 1 through a line 7. After the desulfu rized gas removed with the large parts of H2S and SO2 is sent to a cooler 11 via a line 10 to condense and separate the accompanied steam, it is washed with water in a purification tower 13 to remove the nonreacted H2S and SO2 and discharged or recovered through a line 14.

Description

Изобретение относитс  к процессам избирательной десульфуризации газовых смесей , содержащих сероводород.This invention relates to processes for the selective desulphurisation of gas mixtures containing hydrogen sulfide.

Целью изобретени   вл етс  повыщение степени очистки.The aim of the invention is to increase the purity.

П р и м е р. В реактор из нержавеющей стали в виде колонны с колпачковымитарелками , имеющей внутренний диаметр 27 мм и оснащенной металлокерамической диспергирующей тарелкой с диаметром отверстий 2 мк, загружают установленные количества воды и газов HzS-Na и SOz-Na при 25°С, которые пропускают через расходометры с целью их диспергировани  в воде .PRI me R. Into a stainless steel reactor in the form of a column with cap-shaped plates with an internal diameter of 27 mm and equipped with a metal-ceramic dispersing plate with an opening diameter of 2 microns, the prescribed quantities of water and HzS-Na and SOz-Na gases are loaded at 25 ° C, which are passed through flowmeters with the purpose of dispersing them in water.

Состав газа на выходе реактора анализируют с помощью газовой хроматографии, позвол ющей обнаружить концентрациюThe composition of the gas at the outlet of the reactor is analyzed using gas chromatography, which makes it possible to detect the concentration

H2S или S02 свыше 1000 ч. на миллион до тех пор, пока состав газа не становитс  посто нным . Вли ние технологических параметров на проведение процесса показано в таблице. При зтом рН среды поддерживают на уровне 0,1-2,0 с получением аналогичных результатов, температуру 25-160°С и давление 5-80 кг/см.H2S or S02 is in excess of 1000 ppm, until the gas composition becomes constant. The effect of technological parameters on the process is shown in the table. At this time, the pH of the medium is maintained at a level of 0.1-2.0 with obtaining similar results, a temperature of 25-160 ° C and a pressure of 5-80 kg / cm.
