##### Abstract

Nigeria is faced with high import of petroleum products, incessant shortage of the products and poor petroleum refining status. There is therefore the need to develop local technology in petroleum refining as a sustainable solution to these problems. This work contributes its own quota to this worthy course by designing and fabricating crude distillation unit components for a mini petroleum refinery to process 1 bbl/day of Escravos crude. The unit consists of atmospheric distillation unit and vacuum distillation unit. Components designed and fabricated are: an Atmospheric distillation column, a Vacuum distillation column, an ADU furnace, a VDU furnace, a Condenser, a Reflux drum, 3 Strippers, an AGO-Crude Heat exchanger, a Top Pump-around heat exchanger and a Bottom Pump-around heat exchanger.
Design was done using both manual calculations and ASPEN Plus software. The ASPEN Plus simulation gave: Internal diameter of ADInternal diameter of AD Internal diameter of ADInternal diameter of AD Internal diameter of AD Internal diameter of AD Internal diameter of AD Internal diameter of AD Internal diameter of AD Internal diameter of ADInternal diameter of AD U, VDU and Stripper columns as U, VDU and Stripper columns as U, VDU and Stripper columns as U, VDU and Stripper columns asU, VDU and Stripper columns as U, VDU and Stripper columns asU, VDU and Stripper columns as U, VDU and Stripper columns as U, VDU and Stripper columns asU, VDU and Stripper columns as U, VDU and Stripper columns as U, VDU and Stripper columns asU, VDU and Stripper columns as 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively.7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively.7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively. 7.5cm, 9.9cm and 2cm respectively.7.5cm, 9.9cm and 2cm respectively.7.5cm, 9.9cm and 2cm respectively.
