A simulation tool executing a simulation model and a generating an automated dialog associated therewith. The automated dialog comprises a bot configured for interacting with a user, wherein the dialog is displayed to the user. The bot is integrated with a set of rules that are referenced as a function of input received from the user for furthering the dialog and making a recommendation about the process simulation. In certain embodiments, the simulation tool is configured to select a thermodynamic method for use in a process simulation as a function of the set of rules and the user input.

Interactive guidance system for selecting thermodynamics methods in process simulations

A device for controlling a liquid flow in a vertically extending pipe is disclosed which includes a plate member horizontally disposed in the pipe for receiving the liquid flow thereon and having an opening to permit the liquid received on the plate member to pass therethrough, a tubular guide downwardly inwardly extending from the periphery of the opening and terminating to form a liquid outlet, and a plurality of partition plates disposed on the tubular guide. Each partition plate has an upper end upwardly protruding from the periphery of the opening and a lower end obliquely downwardly extending from the periphery of the opening along the wall of the tubular guide member, so that a plurality of discrete passages are defined on the tubular guide. A cover plate is provided to cover the passages so that the liquid received on the plate member flows through the passages and is discharged from the liquid outlet of the tubular guide to form a vortex flow.

A gas separation process and a unit therefor. The process comprises the steps of: introducing a gas consisting of two or more components into an adsorption system in which adsorbent particles circulate in a fluidized state, thereby to allow, at atmospheric pressure or an elevated pressure, the adsorbent particles to adsorb a gas component to be separated from the gas; transferring the adsorbent particles adsorbing the gas component to a desorption system; and then desorbing the gas component from the adsorbent particles in the desorption system which is regulated to have either a lower pressure or a lower pressure and a higher temperature than the adsorption system.
