چکیده مقاله به فارسی :
با گسترش صنایع نفت،گاز و پتروشیمی در جهان، جداسازی گاز های اسیدی مانند دی اکسید کربن و سولفید هیدروژن بیش از پیش مورد اهمیت قرار گرفته است. استفاده از گروه حلال های آمین جهت حذف آلودگی گازهای اسیدی یکی از روش های مورد توجه در همین راستا می باشد. تولید کف در این گونه سیستم ها از مشکلات رایج و شناخته شده ای است و روش متداول در کنترل کف در صنایع استفاده از مواد کف زدا می باشد. از طرفی به دلیل موقتی بودن اثر ماده کف زدا بر پدیده تولید کف، استفاده از فیلترهای مکانیکی و کربنی بسیار پر اهمیت می باشد. فیلترها وجود الاینده هایی شبیه اکسیژن، سولفور دی اکساید واسیدها در خوراک ورودی به پروسس را کاهش داده و پدیده تجزیه حلال و وجود ناخالصی ها را کنترل می نمایند. آزمایش انجام گرفته نشان داد که در 90 ثانیه اول سطح محلول فیلتر شده از 150 میلی لیتر به 180 میلی لیتر می رسد. این درحالی است که در مدت زمان مشابه سطح کف در محلول آمین بدون فیلتراسیون از 150 به 400 میلی لیتر رسید. به علاوه الودگی روغنی اضافه شده به حلال باعث بالارفتن سطح کف بیش از 500 میلی لیتر شد که نشان گر افزایش ارتفاع کف در زمان وجود آلودگی می باشد.

چکیده مقاله به انگلیسی :
Foam production in the amine solvent system is one of the common problems and the most common method of foam control is the use of anti-foaming agents. Due to the temporary effect of antifoam, the use of mechanical and carbon filters is very important. Filters reduce the presence of impurities in the feed entering the process and control the phenomenon of solvent decomposition and the presence of impurities. The experiment showed that in the first 90 seconds, the level of the filtered solution reached from 150 ml to 180 ml. Meanwhile, in the same period of time, the foam level in the amine solution without filtration reached from 150 to 400 ml. In addition, the oil pollution added to the solvent caused the floor level to rise by more than 500 ml, which indicates the increase in the height of the floor during the presence of pollution.
