An original method for calculating the equilibrium pressure for the formation or dissociation of multicomponent gas hydrates as a function of temperature and composition has been developed. It is applicable to gas and water systems that are in the following phase states: gas–water vapor–ice; gas–water vapor–liquid water. The developed method is sui...

An analysis of the process of filling cavities in articles with a control gas in leakage testing is presented. Based on the results of the analysis an algorithm that describes the process of filling cavities with a gas that produces a reduction in filling time is proposed. The proposed algorithm provides a foundation for automation of leakage testi...

The present work investigates the process of recycling the light fraction formed during the preparation of amines by the interaction of 1,2-dichloroethane with ammonia, by separating amines in a fractionating column. The light fraction, which is an aqueous solution containing about 1 % ethylenediamine and about 2% ammonia, is processed in an electr...

Design flaws of known rotary pulsation apparatuses are analyzed. A new rotary pulsation apparatus design is proposed. The essential technical feature of this design lies in imparting an irregular shape to the flow channels, which ensures increased agitation of the emulsion flow and formation of a more uniform of emulsion structure.
