Abstract: The process for generating at least one warning signal relating to the level in a tank (3) for storing a product (4) comprises the following steps:the storage level of the product in the tank, together with the values of the product quantity consumed during predefined time intervals are determined,these values are placed in memory together with the associated measurement instants,at other successive instantsthe values placed in memory of the product quantity consumed are used to calculate a value of the estimated quantity of product which will be consumed in the future,this estimated value is subtracted from the last measurement value so as to obtain an estimated value of the storage level at a future instant,this estimated value of the storage level is compared with a preset threshold, anda warning signal is generated if the estimated value is less than the preset threshold.

Abstract: In a process for manufacturing fatty alcohols comprising hydrogenating the corresponding fatty acid methyl esters, the hydrogen used for the hydrogenation reaction is regenerated from impure methanol as a by-product of the reaction. The impure methanol recovered from the hydrogenation reactor is conducted to a steam reformer reactor, from whence the regenerated hydrogen is recycled back to the hydrogenation reactor.

Abstract: The separation of a gaseous mixture of at least three components, by permeation, wherein a more permeable component, e.g. hydrogen, is separated from an intermediately permeable component and a less permeable component, e.g. CO.sub.2 and CO, respectively, in a first permeator. The residue from the first permeator, e.g. CO.sub.2 and CO, is introduced into a second permeator in which the intermediately permeable component, e.g. CO.sub.2, is separated from the less permeable component, e.g. CO. The less permeable component, e.g. CO, is then directly and completely introduced into the downstream side of the first permeator, where it rejoins the more permeable component, e.g. H.sub.2. The partial pressure of the more permeable component in the starting gaseous mixture, e.g. H.sub.2, is maintained higher than its partial pressure in the final mixture of e.g. H.sub.2 and CO.
