Semi rigid connections and their influence on steel column behaviour. [PDF]

open access: yes, 1980
A review of the development of the analysis of frames with semi-rigid end restraint is given, including the treatment of frame stability and effective lengths. The available experimental data relating to the moment versus in-plane

TECHNOLOGY OF CYCLIC DISTILLATION IN ALCOHOL PRODUCTION

open access: yesHarčova Nauka ì Tehnologìâ, 2019
Alternate changing of the steaming periods and liquid overflow allows to intensify mass transfer between liquid and steam and to reduce the specific consumption of heating steam in the process of separation of multicomponent mixtures.

CRITERIA OF EFFICIENCY ESTIMATION OF RECTIFICATION COLUMNS

open access: yesIZVESTIYA VYSSHIKH UCHEBNYKH ZAVEDENIY KHIMIYA KHIMICHESKAYA TEKHNOLOGIYA, 2018
This article deals with the efficiency of rectification columns which is often measured by the value of tray efficiency or single height of packing. The analysis of the factors influencing the efficiency of the rectification process was provided. This article shows that the commonly used Murphree efficiency factor in most cases estimates the efficiency

Analysis of the Dynamic Characteristics of the Distillation Column of Plate Type

open access: yesEAI Endorsed Transactions on Energy Web, 2017
The relevance of the study related to the necessity to convert to “unmanned” production in a refinery and, as a consequence, we must derive a mathematical model of the high-octane gasoline process.

Gas isotope thermometry in the South Pole and Dome Fuji ice cores provides evidence for seasonal rectification of ice core gas records [PDF]

open access: yesThe Cryosphere, 2022
Gas isotope thermometry using the isotopes of molecular nitrogen and argon has been used extensively to reconstruct past surface temperature change from Greenland ice cores. The gas isotope ratios δ15N and δ40Ar in the ice core are each set by the amount
