Kodi Ma Desiccant Amakhudzidwa Bwanji ndi Kuchotsa Sulfure?

Mwachidule, m'chilengedwe, fungo la sulfure ndi sulfure mwachilengedwe limaphatikizapo kupopera kwa skunk ndi mazira ovunda. Mbiri ya sulfure ngati chinthu chonunkhira choipa yapangitsa makampani opanga gasi lachilengedwe kunena kuti gasi lililonse lachilengedwe lomwe lili ndi sulfure ndi gasi wowawasa. Kuphatikiza pa fungo lake loipa, sulfure ingakhalenso yoopsa kwa anthu ikakhala yamphamvu mokwanira, komanso imayambitsa kuwonongeka. Chifukwa chake kuchotsa mu mitsinje ya gasi lachilengedwe ndi njira yofunika kwambiri, yomwe imatchedwa kutsekemera kwa gasi lachilengedwe.

Kuti mpweya wachilengedwe uzionedwa ngati wowawasa, hydrogen sulfide iyenera kupitirira mamiligalamu 5.7 pa kiyubiki mita imodzi ya mpweya wachilengedwe. Kutsekemera kwa mpweya wachilengedwe nthawi zambiri kumagwiritsa ntchito njira yotchedwa amine treatment kuti ichotse sulfure m'mitsinje ya mpweya. Sulfur imakhala ndi mphamvu pa amine ndipo ikadutsa mu nsanja yomwe ili ndi amine, sulfure imamatira ku amine ndipo imachotsedwa mumtsinje. Kuchiza amine kumagwira ntchito mofanana ndi kuchiza glycol chifukwa zonse zimagwiritsa ntchito yankho lamadzimadzi kuchotsa zinthu zosafunikira ndi zinthu zina kuchokera m'mitsinje ya mpweya wachilengedwe.

Sulfure imanunkhiza, ingathandizenso. Mwachitsanzo, sulfure imagwiritsidwa ntchito nthawi zambiri mu feteleza, machesi, ndi mankhwala ophera tizilombo ndipo imagwiritsidwa ntchito popanga sulfuric acid yomwe imagwiritsidwa ntchito m'mafakitale ambiri. Sulfure yomwe imachotsedwa mu mitsinje ya gasi yachilengedwe imatha kubwezedwa pogwiritsa ntchito Claus Process ndikugulitsidwa ngati chinthu chosiyana ndi gasi wachilengedwe.

Njira ya Claus ili ndi magawo awiri: sitepe ya kutentha ndi sitepe yothandizira.

Gawo lotentha lapangidwa kuti lisinthe hydrogen sulfide yambiri yochotsedwa mumtsinje wa gasi kukhala sulfure wamba. Izi zimachitika powonjezera hydrogen sulfide ndi mpweya kutentha kwambiri. Pafupifupi 60-70% ya sulfure imapangidwa panthawiyi.

Gawo lothandizira limapangidwa kuti litenge hydrogen sulfide yotsala ndi sulfure yatsopanoyo kuti apange sulfure wochulukirapo powatenthetsa pamodzi pa chothandizira, nthawi zambiri alumina yogwira ntchito ndi titania yapadera. Specialty titania imathandiza kusintha hydrogen sulfide yotsalayo kukhala sulfure ndipo alumina yogwira ntchito imathandiza kuteteza titania ku poizoni wa sulfation chifukwa cha mpweya wolowa mkati.

Pafupifupi 97% ya sulfure yomwe imachotsedwa m'mitsinje ya gasi lachilengedwe imapezedwa pogwiritsa ntchito Claus Process. Ku China, pafupifupi 15% ya sulfure yonse yopangidwa imachokera m'mitsinje ya gasi lachilengedwe.
