In many cases, the enormous energy requirements for distillation make it economically infeasible to carry out the separation. Thermally coupled distillation system (TCDS) is an advanced distillation method that provides significant energy savings of about 30% as compared with conventional distillation column sequences. The most well-known TCDS sequence, the Petlyuk configuration, has some operational challenges due to bidirectional vapour flow, which makes its implementation difficult in two-column mode. To overcome these limitations, a number of unidirectional vapour flow configurations have been proposed in the literature. The work on simulation analysis for such configurations is limited. In this paper, simulation models for two such configurations are developed, analyzed and compared with the Petlyuk and conventional distillation column sequences for separation of equimolar mixture of benzene-toluene-ethylbenzene.</p>10aDistillation10aenergy efficient10aPetlyuk10asimulation10athermally coupled1 aSaxena, Neha1 aMali, Nilesh1 aSatpute, Satchidanand  uhttps://library.ncl.res.in/content/study-thermally-coupled-distillation-systems-energy-efficient-distillation02647nas a2200253   4500008004100000022001400041245013100055210006900186260000900255300001100264490000800275520175400283653003102037653002102068653002802089653002302117653001402140100002102154700003402175700001702209700001702226700002102243856012902264       2026                        eng d  a0257-897200aEnergy efficient electrophoretic coatings of MXene multilayers for enhanced corrosion resistance and tribological performances0 aEnergy efficient electrophoretic coatings of MXene multilayers f  cMAY   a1334270 v5283 a<p>
	Surface wear, friction and corrosion have always been among major challenges faced by industries globally which cause significant economic and energy losses yearly. The recent emergence of two dimensional (2D) MXenes in tribology as protective coatings is noteworthy due to their layered structure, tuneable properties, easy to shear ability, and capability of forming anti-corrosion wear resistant tribo-films. In this work, multiple layers of Ti3C2Tx MXene coatings were applied on stainless steel (SS) substrates via energy electrophoretic deposition (EPD) process at low voltage of 5 V to enhance tribology and anti-corrosion behaviour of substrates. The tribological performance was investigated by rotating ball-on-disk tribometry at 5 N load with rotating velocity and radius of 500 RPM and 3 mm respectively. The effect of multiple coating layers on microstructure and tribological performance was also investigated to optimize the coating thickness followed by the extensive characterization of MXene and developed coatings. Surface hardness and coating thickness increased proportionally with increase in number of coating layers resulting into the maximum values of 311.39 HV and 3.25 mu m respectively. Tribological performance confirmed significant reduction in coefficient of friction (COF) and specific wear rate for MXene coated samples compared to uncoated SS substrates. Precisely, two coating layers' sample (MX2) demonstrated the best performance achieving approximate 41.3% and 65.7% reduction in coefficient of friction (COF) and wear rate, respectively. Further, corrosion studies also confirmed the protective role of MXene layers and great anti-corrosion behaviour of MX2 sample with 72.2% protection efficiency.</p>
