ABSTRACT

The production and analysis of “Ngu” extract for temperature and water requirement for leaching of caustic alkali is the basic objective of this project. The production was carried out by using unit operations and also using the female inflorescence of a palm fruit (Eleasis Guineesis) as raw material. The female inflorescence of palm fruit was size reduced from original dimensions to maintain particle size characteristics. The size reduced bunches were dried at room temperature and at normal atmospheric pressure; after which the sized reduced bunches were burnt at higher temperature. The cooled ashes were dissolved, filtered by using a sieve of mesh size and the filtered solution is the “Ngu” extract. The pineapple content of the alkali leached from Ngu ash was potassium hydroxide. Material and energy balances, equipment sizing with recommended material of construction, costing and profitability analysis was done. It should however, be noted that a profitable project could be embarked upon if the equipments to be fabricated locally which also reduce foreign exchange being extended on the importation of potassium hydroxide.
