Naphta recovery unit
WitrynaThe naphtha recovery unit (NRU) is an important process used to recover the hydrocarbon diluent (naphtha) that is used to assist with bitumen extraction from oil sands [ 1]. Oil extraction from oil sands has drawn considerable public attention due to its energy consumption and ecological footprint.

Naphta recovery unit
Did you know?
The first unit operation (after being desalinated) in a petroleum refinery is the crude oil distillation unit. The overhead liquid distillate from that unit is called virgin or straight-run naphtha and that distillate is the largest source of naphtha in most petroleum refineries. The naphtha is a mixture of many different hydrocarbon compounds. It has an initial boiling point (IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic … WitrynaLight Ends Unit. As shown in Figure 3.2, the Light Ends Unit consists of a sequence of distillation processes to separate the overhead distillate product from the atmospheric distillation column into five streams consisting of methane and ethane (C 2 and lighter), to propane (C 3), butane (C 4), light naphtha, and heavy naphtha.The fraction C 2 and …
