REDUCED EXPANSION FORCES CREATED BY MATERIALS FOR STORAGE OF AMMONIA Russian patent published in 2020 - IPC C01C1/00 G01N3/00 B01D53/04 B01J20/02 B01J20/34 

FIELD: technological processes.

SUBSTANCE: invention relates to storage of ammonia in solid material. Described is a method of controlling the value of mechanical forces applied by solid material for storage of ammonia to walls of a container containing material for storage in its inner volume, when storage material is subjected to saturation/re-saturation with ammonia inside said storage container, said method comprising: a. use of dependence between i. temperature for the process of saturation/re-saturation with ammonia in the material for storage, then T_SAT, as well as the density of the material for ammonia completely saturated with ammonia, then—D_MAT, and ii. hydraulic pressure P_MAT or equivalent mechanical force F_MAT, created by material for storage during saturation/re-saturation at said temperature T_SAT and said density D_MAT, for determination of minimum temperature, then—T_SATMIN, saturation/re-saturation process, wherein said relationship is obtained using an experimental comparison procedure, in which experimental data are obtained, or by computer simulation, b. saturation/re-saturation process at temperature T_SAT, when condition T_SAT≥T_SATMIN, so that P_MAT or F_MAT, applied by material for storage, have values below mechanical strength limit in terms of hydraulic pressure P_LIMIT or hydraulic force F_LIMIT container in inner volume, at which container walls do not undergo plastic deformation or do not undergo deformation of more than 200 % of deformation at point of yield point of container walls. Method for calculating a container for accommodating solid ammonia and container are also described.

EFFECT: improved operational characteristics of material.
