A mathematical model of formation of gas hydrates in cylindrical channel at biphase mixture flow is builded with account of frontal (on surface) and volumetric hydrate formation. The model allows to describe formation and dissociation of hydrates both because of external heat exchange and because of phase conversion temperature effect in a framework of partial stationary method. Some pecularities of formation and growth of hydrate deposits on channel walls are established, an optimal flow rate is found when hydrate growth is slower. Different regims of process are received by calculations, for example, hydrate film grows slower and stops for one. Porous hydrate structure growth ability is analized.
