Abstract:
1. A process for production of synthesis gas from heavy charges comprising: partially oxidizing heavy charges with oxygen or air enriched in oxygen in a presence of vapour carried out at temperatures higher than 1000° C. and pressures equal to or higher than 20 atm; cooling, after partially oxidizing, a synthesis gas obtained, by directly injecting water into the synthesis gas itself followed by separating water effected by means of an adduction pipe surrounded by an open concentric tube open at both ends so as to form a ring through which cooled gas and water can rise, wherein a distance (L) between a lower end of the adduction pipe and a lower end of the open concentric tube must be equal to or higher than x times a diameter (D) of said lower end of said adduction pipe, wherein x varies in relation to a specific gas mass flow-rate (F), expressed in kg/h/cm
