Volatile Organic Compounds (VOCs) having different polarities were absorbed in two viscous waste oils (a transformer oil and a lubricant, whose viscosities are equal to 19 mPa s 79 s, respectively) structured packing (1 m height) operated at counter-current. A synthetic hydrophobic solvent (PDMS 20, silicone oil) water also used as reference solvents. Removal efficiencies of VOCs up 80–90% meas...

The Texas Carbon Management Program is preparing a Front-End Engineering Design (FEED) of the PZASTM (Piperazine with Advanced StripperTM) for CO2 capture at natural gas combined cycle power plant in West Texas. This paper develops absorber design system and studies operational strategies response to ambient temperature swing. uses 2 trains, each train integrates absorption water-wash section o...

In this paper, the effects of two different Particle Size Distributions (PSD) on packingbehavior of ideal rigid spherical nanoparticles using a novel packing model based on parallelalgorithms have been reported. A mersenne twister algorithm was used to generate pseudorandomnumbers for the particles initial coordinates. Also, for this purpose a nanosized tetragonal confinedcontainer with a squar...

In textile industry, marker planning is one of the main operations in the cutting fabric stage. Marker packing is usually used to maximize cloth exploitation and minimize its waste. In this research, a method is used based on new found meta-heuristic imperialist competitive algorithm (ICA) and Bottom-Left-Fill Algorithm (BLF) to achieve optimal marker packing. Function of the proposed method wa...

• Dry pressure drop for two types of complex structured packing is evaluated experimentally and numerically. A numerical model established validated with an average deviation ≤ 20% from the experimental data. The advantages/drawbacks results different computational domains dry study are presented. a wire-based column 16,500 cm 3 produced using periodic rectangular domain 42 . effect penalty on ...

We introduce an algorithmic framework for tuning the spatial density of disks in a maximal random packing, without changing the sizing function or radii of disks. Starting from any maximal random packing such as a Maximal Poisson-disk Sampling (MPS), we iteratively relocate, inject (add), or eject (remove) disks, using a set of three successively more-aggressive local operations. We may achieve...

• Structured packings offer superb performance for intensified chemical separations. Benefits include reduced equipment size and improved separation efficiency. Computational fluid dynamics methods can predict interfacial mass transfer. transfer within each phase. Strong agreement of simulation results with experimental data is possible. This review summarizes the various implemented computatio...
