Mixed-phase Feeds in Mass Transfer Columns and Liquid Separation
The flashing feed sections of crude oil vacuum towers are especially prone to liquid entrainment. This can be detrimental to the performance of the packings/trays above the feed. It is also of disadvantage in case liquid is collected and recirculated back to the furnace. Therefore it is common practice to use special inlet devices that help preventing or minimizing liquid entrainment while maxi...
متن کاملInvestigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System
In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
متن کاملLiquid Secondary Ion Mass Spectrometry
Liquid secondary-ion mass spectrometry (liquid SIMS) is an obsolescent ionization technique that revolutionized the analyses of large biological molecules in the 1980s. The term includes fast atom bombardment mass spectrometry (FAB-MS). The technique has been largely superseded by electrospray ionization. This account will cover the history of the technique, the principles of the operation, and...
متن کاملLiquid mixing and gas–liquid mass transfer in a three-phase inverse turbulent bed reactor
In this research work, hydrodynamic characteristics and gas–liquid mass transfer in a laboratory scale inverse turbulent bed reactor were studied. In order to characterize internal flow in the reactor, the residence time distribution (RTD) was obtained by the stimulus-response technique using potassium chloride as a tracer. Different solid hold-up (0–0.37) and air superficial velocity (2.7–6.5 ...
متن کاملLiquid phase ion mobility spectrometry.
A novel analytical method, called Liquid Phase Ion Mobility Spectrometry (LiPIMS) was demonstrated, where aqueous phase analytes were ionized and introduced into non-aqueous liquids, transported by an external electric field from the point of generation to a collection electrode. Ions were produced from a unique liquid phase ionization process, called Electrodispersion Ionization. Spectra of an...
