CONSTRUCTION OF A PILOT MOTORISED MIXER

ABSTRACT

A motorized mixer of 200 liters capacity was constructed to have the capability of mixing 200 liters of fluid during operation.

The construction of the mixer involves the preliminary measures and calculations on the surface area of the metal sheet.  Some basic workshop practices was carried out during the construction such as the marking out of the metal sheet, cutting of different sizes of the sheet, welding of the prints, assembling of the components parts and painting of the equipment.

The material used in the construction of the mixer is mainly of mid steel.  The mild steel was used for the construction due to its quality cost availability and characteristics.

The cost of constructing the motorized mixer was cheep due to the choice of material selected for the constructional project and it was finally painted with aluminum paint to protect it form corrosion.

The material dimension used in construction of the motorized mixer is as follows:

Length of vessel                                                          700mm

Diameter of vessel                                                      600mm

Length of shaft                                               800mm

Surface area of plastic vessel              1320000mm

Electric motor rating                           733.3v 50/60HZ, 3728.5 watt

7000r pm

RESERVE ESTIMATE OF IMERI BITUMEN DEPOSIT (A CASE STUDY OF IMERI, OGUN STATE, NIGERIA)

The Petroleum industry has become the mainstay of the overall economy of Nigeria, accounting for about 90 per cent of the country’s foreign exchange earrings, about 20 per cent of the Gross Domestic Product, and about 85 per cent of the Federal Government collectable revenue. The demand for this back gold is fast increasing worldwide. Figure 1.1, from Purvin & Gertz’ most recent Global Petroleum Market Outlook study, shows how petroleum product demand has grown since 1995 and how it is expected to continue to grow through 2015. The study shows a 1.7 % per annum growth in worldwide demand and that this growth rate will continue over the next 15 years. The Purvin & Gertz study also states that the growth in crude supplies from 60 million barrels per day in 1990 to 75 million barrels in 2005 will continue up to 95 million barrels per day in 2020. The current growth in transportation fuel demand is outpacing the supply of traditional crude oil sources.
