TECHNOLOGY OF GASIFICATION OF LIQUEFIED NATURAL GAS

A fl ow diagram of gasifi cation of a cryogenic liquid, which is based on the utilization of the liquid′s internal energy to obtain a vapor phase, has been presented. The limiting steam fractions of the two-phase flow in a gasifier have been evaluated as applied to the problems of gasification of methane. Consideration has been given to the conditions of phase separation in the field of mass forces. A numerical scheme of solution of a system of gasdynamic equationsfor the two-phase fl ow in a cylindrical coordinate system in a three-dimensional formulation has been implemented. The results of numerical modeling of the conditions of precipitation of particles with a diameter of 2 to 10 μm from a swirling dispersed fl ow have been presented; the role of the particle size in the dynamics of the process of phase separation has been established.
