- Condensers:<\/span> <\/strong>The duty of the heat exchangers was to condense either pure methanol or a mixture of vapors phases (composed by condensable components as methanol and water, and non-condensable ones, as air). Moreover the condensation had to take place in vacuum conditions.A correct thermal design of the heat exchangers was a critical point in this case. For condensation of gas mixtures (further having non-condensable phases as mentioned) the process doesn\u2019t take place in isothermal conditions like it happens with pure components, demanding thus a very accurate calculation to be done by our engineers. Besides, our Technical Department advised the client for each case about the use of the most suitable cooling fluid, as tower water, or glycol solutions.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

Our solution: Methanol Evaporators and Condensers<\/h2>\n
<\/p>\n
Given the process data, our Engineers did the thermal design both for the condensers<\/strong> and the evaporators<\/strong>, checking for every case different alternative, with the aim to offer the best solution to our client.<\/p>\n
<\/p>\n
With this is mind, we describe as follows the most important points considered in the design of the process equipment:<\/p>\n

- Methanol Vapourisers:<\/strong><\/span>\u00a0Boiling is one of the thermal processes<\/strong> requiring a deeper knowledge by the designer. In this case the evaporation<\/strong> was done by heating the methanol vapors<\/strong> using water steam<\/strong> as service media. Our engineers chose a suitable design to avoid mist flow<\/strong> (what can make it difficult to fully evaporate the entering stream) and oversized suitably the process flowrate<\/strong>, thus ensuring that the required boiling capacity was reached. Our designers chose a suitable design to avoid dry wall mist flow, as it could lead to high tube wall temperatures.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

- Methanol Condensers:\u00a0<\/strong> The condensation<\/strong> hasn\u2019t got so sensitive issues in the thermal calculation<\/strong>, although it is important to take care in the design to choose a suitable baffle geometry<\/strong> and spacing, to ensure a good draining of the condensates<\/strong> and to avoid also vibration risks<\/strong> in the shellside. In this regard, our Technical Department used the latest version of HTRI<\/strong> software that has a specific module for the checking of vibrations.<\/span><\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

Biodiesel Production Process<\/h2>\n
<\/p>\n
The biodiesel is produced by chemical reactions of\u00a0transesterification and esterifications<\/b>, starting from\u00a0vegetable or animal fats and oils<\/b>\u00a0(pure or recycled) that react with short-chain alcohols, as\u00a0methanol or ethanol.\u00a0<\/b><\/p>\n
<\/p>\n
Along this reaction, whose main step takes place in a\u00a0reactor<\/b>, other products and byproducts are processed or generated, as glycerol (useful in the cosmetic industry), soaps or residual water.<\/p>\n
<\/p>\n
Product Specifications<\/h2>\n
<\/p>\n
Biodiesel<\/strong> is a vegetable oil<\/strong> (sometimes it can also be animal-fat based oil<\/strong>) diesel fuel, that is composed by long-chain alkyl esters.<\/p>\n
It can be used either alone (known in this case as B100 biodiesel) or blended in any proportions with conventional hydro-carbon.<\/strong><\/p>\n
Diesel coming from petrol (in this case it is labeled depending on the biodiesel content, i.e. B20 for 20% biodiesel content, etc.).<\/p>\n
<\/p>\n
In our project the lipid raw material was palm oil,<\/strong> although biodiesel can also be obtained from other vegetable oils with or without prior use, as rapeseed or soya oil<\/strong>.<\/p>\n
