✦ Synopsis

The mass balance and phase equilibrium equations that describe the isothermal flash separation of a nonazeotropic system are investigated to determine the conditions under which multiple solutions are computed when a product mole fraction is specified. Necessary and sufficient conditions are established for multiple solutions to occur when a multicomponent mixture is separated.

We build explicitly an infinite number of equilibrium solutions of unloaded Marguerre-von Kármán membrane shells. This construction is based upon the existence of three elementary solutions, together with the solution of a Monge-Ampère equation associated with a partition of the reference configurat
