Mmiri mmiri jupụtara na ya na-agafe n'ime ikuku gasihe nkewa nzachaiji kewaa ntapụ mmiri nke 5 μm na karịa, wee banye na ihe nkewa gas-mmiri nke ngwaọrụ mmiri ịkpọ nkụ iji kewaa mmiri efu. Gas nke kewapụrụ na-abanye na ngalaba mmiri site na paịpụ gas na-arị elu nke ụlọ elu mmiri. A na-efesa triethylene glycol nke e megharịrị n'elu ụlọ elu mmiri, a na-ejikọkwa ya na gas eke site na ala gaa n'elu ụlọ elu mmiri iji mee nnyefe oke na mgbanwe iji wepụ mmiri. A na-ewepụ gas eke nke e wepụrụ mmiri na igwe mkpofu elu ụlọ elu iji wepụ ntapụ glycol karịrị 5 μm wee pụọ na ụlọ elu ahụ.

Mgbe ọ pụtasịrị n'ụlọ elu ahụ, ọ na-abanye na ihe mgbanwe okpomọkụ nke casing wee na-agbanwe okpomọkụ ya na glycol dị nro tupu ọ banye n'ụlọ elu ahụ iji belata okpomọkụ nke triethylene glycol. Gas eke mgbe mgbanwe okpomọkụ gasịrị na-abanye na ihe nkesa nzacha iji kewaa glycol ebu wee banye na pipeline mpụga. Triethylene glycol bara ụba nke amịkọrọ mmiri dị na gas eke na-esi na ụlọ elu nnabata ahụ pụta ma banye na valvụ na-achịkwa ọkwa mmiri mmiri, mgbe nrụgide gasịrị, ọ na-abanye na reflux coil oyi n'elu kọlụm ndozi mmiri mmiri bara ụba wee na-agbanwe okpomọkụ ya na uzuoku ọkụ nke a na-emepụta na reboiler iji nye reflux elu kọlụm. Mgbe o nyechara ikike reflux elu kọlụm, a na-ekpo ọkụ ya ruo ihe dị ka 50 ℃, wee pụọ na coil ahụ gaa na tankị ọkụ triethylene glycol. A na-ebelata nrụgide glycol bara ụba ruo 0.4mpa ~ 0.6mpa na tankị ọkụ, a na-enwukwa gas hydrocarbon na gas ndị ọzọ agbazere na triethylene glycol, a na-ejikwa akụkụ a nke gas dị ka gas mmanụ maka ọkụ reboiler.

Mmiri triethylene glycol nke na-enwu gbaa na-abanye na nzacha igwe iji kpochapụ ihe ndị na-adịghị ọcha n'ime igwe, wee banye na nzacha carbon a na-arụ ọrụ iji tinyekwuo ihe ndị hydrocarbon gbazere na triethylene glycol na ihe ndị mebiri emebi nke triethylene glycol. Mgbe ahụ, ọ na-abanye na ihe mgbanwe okpomọkụ mmiri dị nro nke dị ka efere, na-agbanwe okpomọkụ na triethylene glycol dị nro nke dị elu site na tankị mgbanwe okpomọkụ dị n'akụkụ ala nke triethylene glycol reboiler, ma na-ekpo ọkụ ruo ~150 °C iji banye na kọlụm nhazi mmiri bara ụba.

N'ime ihe eji eme ka mmiri ọkụ triethylene glycol dị n'akụkụ ala nke kọlụm nhazi, a na-ekpo ọkụ triethylene glycol ruo 193 ℃, a na-ekewa mmiri dị na triethylene glycol ma na-agbapụ ya site n'elu kọlụm nhazi site na mmetụta nkewa nke kọlụm nhazi. Glycol dị nro nke nwere ihe dị ka 99% (wt) na-asọpụta site na kọlụm mwepụ mmiri dị nro na ihe eji eme ka mmiri ọkụ dị nro na ihe eji eme ka mmiri ọkụ dị nro na ihe eji eme ka mmiri ọkụ dị ala na tankị mgbanwe okpomọkụ triethylene glycol. N'okpuru ọrụ nke gas akọrọ na kọlụm mwepụ mmiri dị nro, mkpokọta glycol dị nro na-abanye na tankị nchekwa okpomọkụ nwere ike iru 99.5% ~ 99.8%.

N'ime tankị glycol buffer, glycol dị nro nke nwere okpomọkụ dị ihe dị ka 193 °C na-abanye na ihe mgbanwe okpomọkụ glycol dị nro iji gbanwee okpomọkụ na glycol dị ukwuu, okpomọkụ ahụ na-agbada ruo ihe dị ka 100 °C wee banye na ọkpọkọ ahụ. A na-etinye triethylene glycol mmiri dị nro n'ime ihe mgbanwe okpomọkụ gas-mmiri n'èzí ụlọ elu nnabata, mgbe ejiri ihe mgbanwe okpomọkụ gas si n'ụlọ elu ahụ jụọ oyi, ọ na-abanye n'elu ụlọ elu nnabata site na akụkụ elu nke mkpuchi ahụ iji mezue mgbasa mmiri mgbaze.

Gas akọrọ nke sitere na ngalaba paịpụ gas akọrọ dị na mpụga nke ụlọ elu nnabata bụ gas na-ewepụ ihe nke kọlụm ndozi.
