Ọtụtụ ndị mmadụ anụbeghị maka triethyl aluminum (TEAL), mana ọ na-ekere òkè dị mkpa n'ịmepụta ngwaahịa ndị mmadụ na-ahụ ma na-emetụ kwa ụbọchị. TEAL bụ ngwakọta organoaluminum (carbon na aluminom) nke a na-eji emepụta plastik dị elu na nke dị ala, rọba, ọgwụ, semiconductor, na polymers chọrọ maka "mmanya na-aba ụba" n'ime ihe ncha na aka sanitizers.
Ndị polymer na-arụ ọrụ site na ijikọta mkpụrụ ndụ (ma ọ bụ monomers) n'otu n'otu n'ime agbụ buru ibu nke enwere ike iji mee ngwaahịa. Na polymer organic, ọkpụkpụ azụ nke agbụ ndị a bụ carbon na organometallic ogige, dị ka TEAL. Ngwakọta ndị a na-enye carbon achọrọ maka mmeghachi omume polymerization. Na mmepụta nke ụfọdụ n'ime plastik ndị a na-ahụkarị, nchikota TEAL na titanium tetrachloride nwere ike ịmepụta Ziegler-Natta catalysts. Nke a bụ ihe mkpali dị mkpa iji malite mmeghachi omume kemịkalụ nke na-eduga na polymerization olefin nke ukwuu iji mepụta polyethylene na polypropylene.
Ụlọ ọrụ ọ bụla na-echekwa ma ọ bụ na-ahazi TEAL kwesịrị ịṅa ntị na ngbanwe nke kemịkalụ. TEAL bụ pyrophoric, nke pụtara na ọ ga-ere ọkụ ma ọ bụrụ na ikuku kpughee ya. N'ezie, mmeghachi omume siri ike nke kemịkalụ a nwere ikuku oxygen cryogenic bụ otu n'ime ihe kpatara eji ya dị ka mgbaka rọketi mbụ nke mmemme SpaceX. Naanị otu ihe ị ga-ekwu: a ghaghị ịkpachara anya mgbe ị na-eji ihe a eme ihe. Maka ndị na-emepụta rọba na-agbapụta kemịkalụ a kwa ụbọchị, naanị nfuli emebere maka ngwa a ka enwere ike iji. A ghaghị ịkpachara anya iji hụ na ihe na-eme ka ọ ghara ikpughe ikuku n'oge nhazi.
Mgbe ị na-ahọrọ mgbapụta maka ngwa TEAL, izi ezi bụ ihe kacha mkpa. Usoro kemịkalụ ọ bụla na-agbaso otu usoro. Ịgbanye ihe ndị dị mkpa nke ukwuu ma ọ bụ dị nta agaghị arụpụta ihe achọrọ. Igwe nfuli igwe nwere ike ịgbanye ego kemịkalụ achọrọ (n'izizi +/- 0.5%) bụ nhọrọ izizi maka ngwa TEAL na-emepụta kemịkal.
Banyere mgbaba na nrụgide, a na-atụkarị TEAL na olu nke na-erughị galọn 50 kwa elekere (gph) yana nrụgide na-erughị 500 pound kwa square inch nlele (psig), nke dị n'ime oke nfuli ọtụtụ mita. Akụkụ bụ isi nke usoro polymerization bụ nrubeisi zuru oke na ụkpụrụ American Petroleum Institute (API) 675, izi ezi na ntụkwasị obi. TEAL na-ahọrọ nfuli ndị mejupụtara njedebe mmiri mmiri igwe anaghị agba nchara 316, 316 LSS bọọlụ valve na oche, yana polytetrafluoroethylene (PTFE) diaphragm iji gbasaa ndụ kemịkalụ a dị ize ndụ.
Nchekwa na ntụkwasị obi Mgbapụta mita diaphragm nke hydraulically (HAD) nwere ike ịrụ ọrụ ntụkwasị obi ruo ọtụtụ iri afọ ma nwee ogologo oge n'etiti mmezi (MTBR). Nke a bụ isi n'ihi nhazi nke mgbapụta ahụ. N'ime njedebe mmiri mmiri, olu na nrụgide nke mmiri mmiri hydraulic n'otu akụkụ nke diaphragm hà nhata na nrụgide nke usoro nhazi ahụ n'akụkụ nke ọzọ, nke mere na diaphragm na-ejigide nha nha n'etiti mmiri abụọ ahụ.

Ọ bụ ezie na ogologo ndụ dị mkpa, a ga-ebute ụzọ na ntụkwasị obi na-enweghị nkwụsị. Igwe nfuli igwe maka ngwa TEAL kwesịrị ịbụ nke nwere valvụ nyocha dị mkpa iji belata ụzọ mgbapu nwere ike.
