The paper introduces an approximate analytical method for calculating the melting time of a sludge cryoproduct in a vertical cylindrical tank upon drainage storage. We studied the problem of finding the interface position between pure liquid and sludge with account for heat flows from the side of the walls and the area of pure liquid. It is assumed that the region of sludge is isothermal and has a melting point of the solid phase, the slush-pure liquid interface is flat, and the free surface of the liquid is stationary and has a saturation temperature at a given pressure. The temperature in the region of pure liquid is linearly distributed. The obtained approximations allow us to estimate the melting time of the sludge cryoproduct in the tank without a detailed calculation of the temperature fields in the region of pure liquid and can be used as generalizing dependencies in experimental studies
