The Use of Locally Produced Lime for Clarification of Juice in the Cane Sugar Industry

Juice purification using lime is a standard established practice in the sugar industry allover the world. In order to remove impurities from juice, the juice is treated mechanically, thermally and chemically. The main compound for chemical treatment is CaO in Association with flocculants (polymers), which precipitate the soluble salts and colloids in the juice as insoluble ones. In Sudan...

Modeling, Simulation and control of a rotary dryer

Drying is the final step in the production of solid sugar from sugar cane. In-order for the sugar to be transported and stored; the final moisture content leaving the sugar mill must be carefully controlled at a minimum specified level. The basic problem in Assalya factory is the declining control systems, and quality of the final product, which is due to un- even distribution of the moisture...

Utilization of Petroleum Coke as Alternative Fuel in Cement Kilns

In this study the feasibility of utilizing petroleum coke as alternative fuel in cement kilns was investigated . The study is a tempt to reduce cost of production in which the fuel represents more than 30 % because of the high price of fuel oil which ranges between 205 to 215 $ compared with the price of petroleum coke between 40 to 50 $ ( FOB) . The goal of the study is to...

Control & Monitoring Petroleum Pipelines Corrosion

internal corrosion that occur between pipe internal surface and petroleum product compounds. The present study aimed to investigate the effect of different environments and different kinds of soil through which pipeline buried extends from Shagara (Khartoum) to Port Sudan, and it is also aimed at the detection of the effectiveness of coating and cathodic protection system that it has followed....

Potentials for Energy Saving in Cane Sugar Industry

This work investigates the possibilities of saving energy (heat and electrical) in the cane sugar factories in order to save bagasse for co-generation. Co-generation is a recent trend in the cane sugar industry, which can generate huge income for the sugar factory. Many possibilities for energy saving have been considered in this work. Emphasis was made on two fields, namely the application of...

Study Of Hydrodynamics And Mass Transfer Of Oil Emulsion In A Pilot Scale Sieve Tray Column

A study of primary and secondary treated liquid petroleum wastes in a pilot sieve tray column has been undertaken. The literature related to this type of extractor and the relevant phenomena of droplet break-up and coalescence, drop size and drop mass transfer have been reviewed. The method of treatment in local refineries has been investigated and it is observed that the primary and...

Evaporative Recovery of Basic Chromium Sulphate from Residual Chrome Tanning Liquor

This research was concerned with the concentration of residual chromium tanning liquor by evaporative techniques and the re-use of this concentrated chromium liquor for tannage after adjustment with a make-up of basic chromium sulphate powder.Twelve samples of the residual chromium liquors were collected randomly from ALNASR and the White Nile Tanneries. They were analysed mainly for Cr2o3...

PRODUCTION OF ETHANOL FROM MOLASSES IN SUDANESE SUGER FACTORIES

The aim of this study is to investigate the potentiality of producing absolute ethanol as a renewable energy from molasses. The Sudan have five operating sugar factories with a considerable amount of molasses as by product. The amount produced per year amounts to 442 thousand Tons approximately, which can be transformed to absolute alcohol. The important properties of molasses mainly...
