Kaituku Waeine Whakamaerotanga TEG Kounga Kairangi - He paheketanga molecular sieve dehydration – Rongteng

Whakaahuatanga

Ko te molecular sieve dehydration skid he taputapu matua i roto i te pure hau maori, te whakamahana hau maori ranei. Ko te tatari molecular he karaihe aluminosilicate whakarewa alkali me te hanganga anga me te hanganga microporous rite. I te wa e haere ana te hau kai kei roto i te wai tohu i roto i te moenga tatari ngota i te pāmahana rūma, ka uru te wai me te mercaptan, na reira ka whakaiti i te wai me te ihirangi mercaptan i roto i te hau whangai, ka mohio ki te kaupapa o te whakamakuku me te whakaheke. te tukanga adsorption o te tatari rāpoi i te nuinga o kawea i roto i te pāmahana iti me te pēhanga teitei, i kawea te whakaoranga desorption i roto i te pāmahana teitei me te pēhanga iti. I raro i te mahi o te pāmahana teitei, te ma me te iti te pehanga regeneration hau, te adsorbent tatari rāpoi tuku i te adsorbate i roto i te micropore ki te rere hau whakaora tae noa ki te nui o te adsorbate i roto i te adsorbent tae ki te taumata tino iti, me te whai i te kaha ki te mimiti wai me te mercaptan i te hau kai, te mohio ki te whakahou me te hangarua tukanga o te molecular.
Ko te tikanga molecular sieve ko te ahua o te tikanga whakamaoritanga hohonu, he maha nga wa e whakamahia ana i roto i te iti o te wera o te wera o te wehenga, penei i te whakaoranga o te hau o te hau (NGL) me te tukanga whakamaroketanga i roto i te hanga o te hau taiao (LNG). I tua atu, ka whakamahia hoki te whakamaroke tatari molecular i roto i te hanga o te hau maori kōpeke mo te wahie waka.

Ko te whakamaroke molecular sieve i te nuinga o te waa e pa ana ki nga waa e whai ake nei:
a. Kei raro iho i te – 40 ℃ te haupapa o te hau maori.
b. He pai mo te whakahaere i te haupapa hauwai o te hau maori pehanga teitei.
c. Ka maroke te hau maori, ka purea i te wa ano.
d. Ina maroke te hau maaori kei roto H2S, ka rewa ki te glycol, ka puta te whakaputanga o te hau whakaora.
e. I te wa e hiahia ana te LPG me te NGL ki te tango i nga tohu sulfide (H2S, CO
COS, CS2, mercaptan) i te wa ano.

Tūtohi rere

Ka whakamahia nga kaiwhakatakoto moenga mo te whakamaroketanga o te tatari mole, no reira kia rua nga adsorber o te waeine, ko tetahi kei roto i te waahi whakamaroke whakamaroke, ko tetahi i te waahanga whakaora me te whakamatao. A, no te te kaha o te waeine he tino nui, ka taea hoki te whakarite i te tukanga pourewa maha.
