Thanks for all your hard work on the case over the last year.

I was very impressed by your performance under cross examination and in the hot tubbing session. You got the tone absolutely spot-on in terms of explaining your position with authority whilst recognising your obligations to be a neutral expert.

I wanted to thank you again for all your help and all the time you put in preparing for the hearing. I know cross-examination isn’t fun, but on the whole I thought you went well and you stood your ground.– I have enjoyed working with you and learning just enough about LPG plants to be dangerous

Case study

Vegetable Oil production experience

A preliminary study was carried out for the Government of Algeria on behalf of UNIDO, on the existing state of the vegetable oil industry in Algeria.

This covered the agricultural and marketing aspects of oil production and the processing of oils and fats into a range of derivatives such as margarine, fatty acids, but the alkyd resins and soaps, glycerol. This led to a study of the feasibility of establishing two new large solvent extraction and soap complexes.

Salt Industries - Expert of Choice

Trusted By Major International Concerns

Oman Government, UNIDO, Caribbean Development Bank, Omnivest,
Egyptian Government Salt and Soda Co Ltd, Iran Government.

Edible & Preservatives

As well as being vital to the human diet, salt is important as an antiseptic and preservative. The normal urban per capita consumption is around 10kg per annum, with the foodstuffs processing industry of highly developed countries (canning, baking, fish and meat packing, curing and tanning of hides) accounting for another 5kg per head per annum.

Chemical derivatives of salt

Worldwide, the main use for salt is as a feedstock for chlorine and sodium chemicals (the chloralkali industry) and may amount to 60–90% of demand in industrialised countries.

The leading chlorine derivative is the plastic polyvinyl chloride (PVC), usually manufactured from ethylene and chlorine. Next in importance is hydrochloric acid, used in metal processing (commonly steel), oil well acidizing and starch hydrolysis. Chlorine itself is used for water purification, textile bleaching and pulp and paper manufacture.

Salt derivatives number in the hundreds, and also include soda ash and sodium bicarbonate.
