Title
(AR) طريقه متجدده وتركيب لازاله الكبريتيدات من تيارات الغاز
(EN) REGENERATIVE METHOD AND COMPOSITION FOR REMOVING SULFIDES FROM GAS STREAMS.
Abstract
(AR)
طريقه وتركيب لازاله الكبريتيدات من التيارات الغازيه تشتمل الطريقه على تلامس تيار غاز محتوى على كبريتيد الهيدروجين مع مخلوط ازاله مائى يشتمل على مركب ازاله ايون غيرعضوى وعامل اكسده حيث يتم تجديد على الاقل جزء من مركب الازاله مع غاز يحتوى على الاكسجين واعاده جزء من مخلوط الازاله المائى الى منطقه التلامس ويتكون مركب الازاله من ناتج تفاعل الدهيد وامين .

(EN)
A METHOD AND COMPOSITION FOR THE REMOVAL OF SULFIDES FROM GASEOUS STREAMS THE METHOD INCLUDES CONTACTING THEE SULFIDE CONTAINING GAS STREAM WITH AN AQUEOUS SCAVENGING MIXTURE WHICH INCLUDES A SCAVENGING COMPOUND AN INORGANIC IN AND AN OXIDATION CATALYST REGENERATINGE AT LEAST A PORTION OF THE SCAVENGING COMPOUND WITH AN OXYGEN CONTAINING GAS AND RETURING AT LEAST A PORTION OF THE AQUEOUS SCAVENING MIXTURE TO THE CONTACTING ZONE A SCAVENGING COMPOUND CONSISTING OF THE REACTION PRODUCT BETWEEN AN ALDEHYDE AND AN AMINEE IS ALSO PROVIDED.
