    • Process for manufacturing dichloropropanol according to which: a) in a liquid reaction medium containing water, which is in contact with a gaseous phase, glycerol is reacted with hydrogen chloride under a partial pressure of hydrogen chloride in the gaseous phase greater than 0.2 bar absolute, and b) at least part of the liquid reaction medium and optionally part of the gaseous phase from step (a) is (are) subjected to at least one separation operation and, prior to said separation operation, the part of the liquid reaction medium and the part of the gaseous phase from step (a) is (are) subjected to: bi) at least one treatment for reducing the weight ratio between the hydrogen chloride and the water in the part of the liquid reaction medium so as to attain a ratio less than or equal to the weight ratio between the hydrogen chloride and the water in the binary azeotropic hydrogen chloride/water composition at total pressure of the separation operation, and/or bii) at least one treatment for reducing the weight ratio between the water and the dichloropropanol in the part of the liquid reaction medium so as to attain a ratio less than or equal to the weight ratio between the water and the dichloropropanol in the ternary water/dichloropropanol/hydrogen chloride azeotrope at total pressure of the separation operation.

    • Process for the manufacture of at least one ethylene derivative compound starting a hydrocarbon source according to which a) the hydrocarbon source, optionally containing fraction E1 recycled from step d), is subjected to a simplified cracking which produces a mixture of products containing ethylene and other constituents; b) the said mixture of products is subjected to a first separation step S1 which consists of separating said products containing ethylene and other constituents into a fraction containing the compounds which are lighter than ethylene and part of the ethylene called fraction F1 and into a fraction F2; c) fraction F1 is sent to an ethylene recovery unit in which it is separated into a fraction enriched with ethylene called fraction E1 and into a fraction enriched with the compounds which are lighter than ethylene called light fraction; d) fraction E1 is recycled to step a) or is conveyed to the manufacture of at least one ethylene derivative compound; e) fraction F2 is subjected to a second separation step S2 which consists of separating fraction F2 into one fraction enriched with ethylene called fraction E2 or into two fractions enriched with ethylene called fractions E2a and E2b, and into a fraction enriched with ethane and hydrocarbon containing at least 3 carbon atoms called heavy fraction; f) fraction E2 or fractions E2a and E2b are then conveyed to the manufacture of at least one ethylene derivative compound.
