Steady-state and non-steady state operation of counter-current chromatography devices

Journal of Chromatography A, 2013
Different variants of separation processes based on steady-state (continuous sample loading) and non-steady state (batch) operating modes of CCC columns have been analyzed and compared. The analysis is carried out on the basis of the modified equilibrium cell model, which takes into account both mechanisms of band broadening - interphase mass transfer ...

Multiple Steady States in FCC Unit Operations

Chemical Engineering Science, 1988
Abstract Commercial fluidized catalytic cracking (FCC) units potentially can exhibit steady-state multiplicity owing to the net exothermicity of the process and the complex interactions that exist between the reactor and regenerator heat balances.

Steady state operation of spherical tokamaks

Nuclear Fusion, 2000
For a fusion power plant to be economically and technologically attractive, it should be as compact as possible and capable of `steady state' operation. One approach is based upon the spherical tokamak (ST) concept. This configuration features many of the qualities of the conventional aspect ratio tokamak, such as good confinement and MHD stability ...

Steady-state operability characteristics of reactors

Computers & Chemical Engineering, 2000
Abstract Operability analysis helps the process designer to consider process control issues quite early in the design process. This analysis should lead to the calculation of measure which quantifies the operability of a design. Search for this measure has been an active area of research in the last two decades.

Chapter 6: Steady state operation

Nuclear Fusion, 2007
Significant progress has been made in the area of advanced modes of operation that are candidates for achieving steady state conditions in a fusion reactor. The corresponding parameters, domain of operation, scenarios and integration issues of advanced scenarios are discussed in this chapter.

Determination of Steady State Gas Turbine Operation

Volume 1: Aircraft Engine; Ceramics; Coal, Biomass and Alternative Fuels; Controls, Diagnostics and Instrumentation, 2012
Repeatable measurement of engine performance requires the system to be near steady state. A technique is presented to assess how close engine operation is to steady state. It estimates the rate of change of the assessed parameter across the sample time and provides an associated confidence interval.

Operation of Transmission Lines at Steady-State

2020
For the calculation of tensions and currents, at the beginning and the end of transmission lines (TLs), in steady-state, it is necessary to develop models that represent TLs. These models are obtained for short-length, medium-length, and long-length TLs. In practice, all real circuits are distributed parameters.

Steady-State Operation

2012
Mathematical model of electrical machine contains differential and algebraic equations describing the machine operation in given supply conditions and given load. Using the model, it is possible to derive the changes of the rotor speed, electromagnetic torque, the air-gap flux, and phase currents during transients and in steady-state conditions.

Profile control for steady-state operation

Plasma Physics and Controlled Fusion, 1998
Large departures from standard L-mode confinement scaling laws are now being observed in most tokamaks which appear promising for relaxing the plasma current constraint and therefore open the route to high-performance steady-state operation with high bootstrap current fraction. Prospects of the weak or reversed magnetic shear scenarios for steady-state
