How do I translate this sentence? About butadiene
Thread Content
A foreigner sent some information regarding butadiene; I can’t translate the following sentence: The effluent from the CATOFIN unit that feeds the isoprene unit will contain 48 to 50 percent isobutylene, along with unreacted isobutane, as well as a few percent of normal butenes and butadiene. The flow rate of the effluent from the CATOFIN unit is 38,000 to 40,000 kg/h. This post was last edited by niuky on 2009-3-21 at 10:59
Trial translation: The effluent from the CATOFIN process unit serves as feed for the isoprene process unit; its composition includes 48-50% isobutylene and unreacted isobutane, along with small amounts of butylene and butadiene. The discharge flow rate of the CATOFIN process unit is 38,000 to 40,000 kg/h.
Firstly: CATOFIN refers to the Catofin process developed by ABBLummus Company. In the feed used in the CATOFIN unit for the production of isoprene, 48-50% is butylene along with unreacted butane are present, along with small amounts of butene and butadiene. The flow rate of the CATOFIN unit is 38,000 to 40,000 kg/h. Note: In the chemical industry, “unit feeding” refers to “the amount of feed per unit””
\"Unit\" refers to a component or device; it depends on whether these two units are two \"components\" within a single integrated system, or two separate \"devices\" used for independent material accounting in a factory. The effluent from the CATOFIN unit, which serves as the feed for the isoprene unit; the output/product of the CATOFIN unit/device enters the isoprene unit/device
\"Unit feeding\" can be translated as \"unit feed rate\"; personally, I think \"unit\" should serve as the head noun in CATOFIN, with \"feeding the isoprene unit\" acting as a postpositive adjective. If we go by what you say, then the use of the noun \"the isoprene unit\" seems odd. Is this explanation acceptable?
What you say makes sense; I didn’t look carefully enough. The entire phrase “feeding the isoprene unit” serves as an adjective describing “The effluent of the CATOFIN unit”. \"Will have\" is the verb phrase; therefore I am correcting my translation. In the output from the CATOFIN unit, which receives isoprene units as feedstock, 48-50% consists of isobutylene and unreacted isobutane, along with small amounts of butylene and butadiene. The flow rate of the CATOFIN unit is 38,000 to 40,000 kg/h.
