Abstract

Last years the requirements to cleanliness of cryogenic agents grow. Impurity contained in them not only reduce the quality of liquid products, but can affect on reliability and safety of systems in which they are used. One of the reasons of increase a concentration of impurity in liquid cryoproducts is their contact with air at storage and transportation. The reasons resulting to pollution by impurity of liquid cryoproducts are investigated. The description of systems of storage and transportation is resulted, recommendations under the prevention of pollution of liquid cryoproducts are given. The methods and results of experimental researches of processes of increase of concentration CO2 in liquid oxygen or argon CO2 and oxygen in liquid nitrogen is described. It is offered for the prevention of pollution of liquid cryoproducts to store and transport them in the equipment at the pressure exceeding atmospheric.
