Subject: что такое bitumen blowing unit (BBU) (petrochemistry) chem. контекста мало....catalytically blown short residue from ... crude could produce bitumen... decided to use a local contractor to design the Bitumen Blowing Unit (BBU) for the ... facility |
|
имхо: установка окисления битума |
| спасибо, хороший вариант, пока его напишу |
| а может быть это установка подачи битума? |

2 morrison: нет, речь именно об окислении, как явствует из учебника (см. ниже - жирный шрифт мой): Special grades are manufactured by blowing air through the hot liquid bitumen in a BITUMEN BLOWING UNIT. What type of reactions take place when a certain bitumen is blown to grade? Bitumen may be regarded as colloidal system of highly condensed aromatic particles (asphaltenes) suspended in a continuous oil phase. By blowing, the asphaltenes are partially dehydrogenated (oxidised) and form larger chains of asphaltenic molecules via polymerisation and condensation mechanism. |
