2-Octanol from Castor Oil

§1What this business is

2-Octanol (capryl alcohol) is a clear liquid made from castor oil. It usually comes as a by-product of sebacic acid plants, but this profile proposes a stand-alone unit: castor oil is saponified with caustic lye in a glass-lined reactor, heated with sodium carbonate, and the 2-octanol is recovered by vacuum distillation. It is used to make plasticisers, as a solvent in rubber processing, as a flotation agent in coal and agro-chemicals, as fibre oil, and to make perfumery esters. Although the profile is titled 'Medicated / Perfumery Oil', its content is entirely about 2-octanol. It says India's capacity is small and about 85% of world supply comes from Chinese sebacic acid makers.

Capacity: About 3,000 t of castor oil a year in, giving about 1,110 t of crude and about 1,100 t of pure 2-octanol (plant output 4.5 t a day); turnover about ₹900 L a year at full capacity.

How the investment is worked out: Fixed assets ₹76.50 L (land and development 1,000 sq m ₹2.50 L, buildings 250 sq m ₹10 L, plant and machinery for 4.5 t a day ₹35 L, other fixed assets ₹15 L, preliminary and pre-operative ₹8 L, contingencies ₹4.50 L) + working-capital margin ₹23.50 L = ₹100 L, which the text calls the block cost. The cost table's total line and the means of finance print ₹175 L (promoter ₹44 L, term loan ₹131 L). Full working capital is ₹94 L.

Working capital: ₹94 L in all: promoter margin ₹23.50 L, bank borrowing ₹70.50 L. About 3,050 t a year of commercial/FSG castor oil plus caustic lye.

Profile from 2018 — machinery and material prices will be higher now.
