The present invention comprises one or more organic solvents that create a non-aqueous organo solvent delivery system, (NOSDS), and one or more Organo Polycarboxylate functionalities, OPCF, that results in a stable, non-aqueous solution that can easily, safely, evenly and economically coat nitrogen source granules and/or be added to a mobile liquid form of a nitrogen source such as an aqueous dispersion, pressurized ammonia gas or molten urea and/or molten modified urea. Using these solvents provides more flexibility for nitrogen source manufacturers to produce nitrogen sources designed for a particular soil or plant. The liquid solutions are comprised of NOSDS and OPCFs and one or more of a) nitrification inhibitors, b) urease inhibitors, c) pesticides, d) fungicides, e) herbicides, f) insecticides and g) micronutrients.

A refrigerant recovery system is equipped with an extraction pipe, a stabilizer holding container, a recovery pipe, a recovery container, and a recovery device. The extraction pipe is connectable to a refrigerant extraction port of an air conditioning apparatus. The stabilizer holding container is connected to the extraction pipe—and holds a stabilizer. The stabilizer holding container causes refrigerant guided by the extraction pipe to come into contact with the stabilizer. The recovery pipe guides the refrigerant discharged from the stabilizer holding container. The recovery container is connected to the recovery pipe and recovers the refrigerant guided by the recovery pipe. The recovery device causes the refrigerant to move from the refrigerant extraction port to the recovery container. The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.
