In the present thesis, a gasifier was simulated and designed using the Aspen HYSYS software in its version 8.0, using anthracitic coal as the raw material, a predominant resource in the upper Chicama area of the Liberta. The characteristics of the anthracitic coal in this area, as well as the conditions of the other feed streams to the reactor, affect the final conditions of the product gas and the dimensioning of the pilot scale gasifier. Once the different runs in the simulator have been started, it is possible to observe the behavior of these variables, that is, the conditions of the feeding, with which the optimum ranges for the process can be set. The simulation of a dragged gasifier that processes 1000 kg / h of slurry based on anthracite carbon, can use mass flow values obtained by stoichiometry (Oxygen: 712.3 kg / h and steam: 338.33 kg / h) which are found as optimal values of the range studied. In addition, it is confirmed that the composition of the oxygen current influences the calorific value, proposing that percentages less than or equal to 5% of N2 be used. On the other hand, the use of a carbon steel reactor is proposed due to its greater resistance to the tension and temperature of operation, to have a total height of 2,515 m, a diameter of 0.4572 m and a capacity of 0.4129 m3. These results are theoretically feasible, and can be used as a basis for real cases in the energy industry since this area has not been developed yet and the bibliography on the subject in our country is still scarce
