Ụzọ kacha mma iji sachaa sodium Hydrosulfide nke ọma

Mụrụ

N'ụlọ ọrụ petrochemical, ụlọ ọrụ mmepụta ihe na-emepụtakarị gas acidic n'oge ọrụ nhazi dịka mwepụ vacuum na mgbawa catalytic. Gas acidic ndị a na-abụkarị 85%-95% hydrogen sulfide, 3%-10% carbon dioxide, gas organic 2%-5%, na ihe ndị ọzọ dị 0.5%-3%. Ụlọ ọrụ mmepụta ihe nta na nke ọkara na-ejikarị mmiri soda caustic 30% eme ihe iji nara gas acidic a na-emepụta n'oge a na-eme ka ọ dị ọcha. Caustic soda na-emeghachi omume na hydrogen sulfide iji mepụta Sodium hydrosulfide. Mgbe ntinye sodium hydrosulfide na ngwọta ruru 30%, a na-etinyekwu uche na ngwọta ya. Mgbe akpịrị ịkpọ nkụ na itinye uche na ya gasịrị, ọdịnaya sodium hydrosulfide dị na ngwọta nwere ike iru 70%, a na-ahazi sodium hydrosulfide ka ọ bụrụ mpekere.

Otú ọ dị, ọnụnọ nke carbon dioxide na gas acidic na-emepụta sodium carbonate adịghị ọcha n'oge usoro ọgwụgwọ, nke na-emetụta ịdị ọcha nke ngwaahịa sodium hydrosulfide. Na mgbakwunye, iji slicer na-emepe emepe na-egbujisị sodium hydrosulfide a wụrụ awụ nwere ike iduga mmeghachi omume oxidation na oxygen dị na ikuku, na-emepụta thiosulfate, nke na-adịkarị njọ ma sie ike ịchekwa. Iberibe nke mepere emepe na-ahapụkwa ikuku na-akpasu iwe, na-emerụ ebe mmepụta ihe.

1. Nkewa nke Centrifugal:

Nyefee ihe ngwọta nke sodium hydrosulfide gbadoro ụkwụ site na tankị ịta ahụhụ gaa na centrifuge kwụ ọtọ maka nkewa, nweta nnu kristal na monohydrate sodium hydrosulfide gbazere.

2. Mkpuchi mkpuchi na oyi:

Zipụ sodium hydrosulfide monohydrate a wụrụ awụ, mgbe nnu chara chara, na tankị na-ekpo ọkụ maka ikpo ọkụ. Mgbe ahụ, gbanye ya n'ime ngwa nju oyi na-ekpo ọkụ ka ọ dị jụụ ma sie ike n'ime mpempe akwụkwọ dị mkpa.

3. Akpa akpaaka:

A na-ewepụta mpempe sodium hydrosulfide site na valvụ kpakpando n'ime igwe akpa akpaka maka nkwakọ.

Ọzọkwa, usoro nchacha maka sodium hydrosulfide gụnyere usoro ndị a:

1. Nyefee sodium hydrosulfide concentrated solution from the concent tank to a kehoraizin ịghasa centrifuge maka nkewa, nweta crystallized nnu na molten monohydrate sodium hydrosulfide.

2. Zipu nnu kristal nke enwetara site na centrifugation na onye na-ehicha ihe, ebe ọ na-ebute mmiri mmiri na-ekpo ọkụ na ngalaba kpo oku nke elu oyi akwa nke dryer, wee banye n'ime akụkụ dị jụụ nke ala oyi akwa maka oyi tupu anakọta ya dị ka onye na-ahụ maka ọgwụgwọ mmiri maka iji mee ihe n'ọdịnihu.

3. A na-ezigara sodium hydrosulfide monohydrate a wụrụ awụ, mgbe nkewa nke nnu kristal, na-ezigara na tank mkpuchi na-ekpo ọkụ maka ikpo ọkụ. A na-atụba ya n'ime igwe na-ekpo ọkụ na-ekpo ọkụ maka ime ka ọ dị jụụ ma sie ike n'ime mpempe akwụkwọ dị mkpa.

4. A na-ewepụta mpempe akwụkwọ sodium hydrosulfide site na valvụ kpakpando n'ime igwe akpa akpa akpa maka nkwakọ.

5. A na-emeso akụkụ gas nke a na-enweta site na tankị mkpuchi na-ekpo ọkụ na ihe na-ekpo ọkụ na-ekpo ọkụ site na usoro ọgwụgwọ gas n'efu.

Usoro a na-ebu ụzọ kewapụ nnu agwakọta kristal, dị ka sodium carbonate, na sodium hydrosulfide concentrated solution. Mgbe ahụ, sodium hydrosulfide monohydrate a wụrụ awụ na-esi ike ozugbo ka ọ bụrụ mpempe akwụkwọ dị mkpa site na iji igwe nju oyi. N'ikpeazụ, a na-eji igwe akpa akpa akpa akpakọ ngwaahịa a.
