In an embodiment, an entity can use the alphanumeric codes to assure that it maintains communication with contacts developed by its employees.

Abstract: A method of producing an atmosphere suitable for plant growth and providing an atmosphere comprising the steps of supplying hot flue gases, cooling the flue gases to condense the water vapor contained therein, allowing said condensed water vapor and the flue gases to remain in intimate admixture for a time period sufficient for the condensed water vapor to absorb at least a portion of the flue gases and promote inter-reaction, spraying the condensed water vapor within a substantially enclosed chamber, and passing the non-absorbed portion of the flue gases through said chamber at a relatively low velocity. There is also disclosed an apparatus adapted to carry out the method of the present invention.
