“…Over the same range the viscosity of the IL will be reduced and the dissolution capacity for toluene, strengthened. Unfortunately, the latter contribution is not sufficient to offset the decrease in the removal efficiency, therefore, 8 20 °C is the optimal temperature for absorbing toluene in the IL.…”

“…VOCs are the primary precursors of fog and haze [2,3], which create severe smog conditions and affect the health of over 800 million people in east China. Currently, the technologies used to control VOCs emissions can be classified under two categories: (i) destructive methods, such as chemical oxidation and biological oxidation [4][5][6] and (ii) recovery processes that make use of absorption/adsorption, condensation and membrane separation methods [7][8][9]. Compared to the destructive methods, the absorption methods have attracted considerable attention because of their simplicity, safety, recyclability and low cost [10][11][12][13].…”

A novel method of removal of volatile organic compounds (VOCs) using the ionic liquid [Bmim][NTf2] as an absorbent is developed as a contribution to dealing with recent severe smog incidents in China. The effects of concentration, temperature and flow rates on the ability of [Bmim][NTf2] to absorb VOCs were studied using toluene as a model volatile organic pollutant. The potential of the use of [Bmim][NTf2] as an absorbent for VOCs is shown by the solubility of toluene in the ionic liquid; the absorptivity of the ionic liquid for toluene; and the fact that absorbed toluene can be removed easily from [Bmim][NTf2], permitting recycle of the ionic liquid in multiple reuse phases. The solubility of toluene in [Bmim][NTf2] is 61.5% at 20 °C and atmospheric pressure; the highest absorptivity of [Bmim][NTf2] for toluene is 98.3%, achieved at a toluene concentration of 300 ppm and a flow rate of 50 mL min−1 at 20 °C; and the absorptivity of the ionic liquid is >94% over a wide range of conditions. The ionic liquid can be recovered and recycled in the absorption process at least five times, reducing the reagent cost in the VOC removal process

“…are suitable when the emission mixture is not very complicated and the recovered chemicals will have some economical value either directly to the process from where they are emitted by re-use or then by selling the recovered chemicals further. At present VOCs are used in process industry as solvents, cleaners, lubricants and fuels [181]. Otherwise, destruction based methods prevail.…”

Volatile organic compounds (VOCs) are harmful to environment and human health. Catalytic oxidation has been used in VOC abatement for over 60 years, and it has proven to be an effective technology. A large variety of VOCs set high demands for the treatment, and therefore catalytic oxidation needs still to be developed further. This paper reviews current aspects and future research needs related to VOCs and catalytic VOC treatment concentrating on solvent-based, chlorinated and sulphur-containing VOCs.

“… An olefin compression section has the task of separating the pyrolysis gasoline, and must meet the requirements of pressure enhancement up to the desired value for  All the previously cases of EISEN studied in the literature 10,11,13,14,16 concern the separation of a pollutant before emitting to the environment. Selection of the case of olefin compression section to be studied as an instance of EISEN aims in broadening the perspective of application of these methodologies into industrial process design and synthesis rather than end-of-pipe and in-plant waste treatment.…”

-When latent heat is transferred in a heat exchanger network, the formation of the second phase creates an opportunity for separation. This network is known as a Heat Induced Separation Network (HISEN). HISENs have been extended to include pressure adjusting devices for improving the thermodynamic feasibility of the network. This extended network is termed an Energy Induced Separation Network (EISEN). Most examples of EISENs in the literature are environmental pollution treatment case studies which do not require liquid phase mass integration or shaft power integration. They assume a predetermined extent of separation, and mostly are based on conceptual methods of design. This paper explains how the optimization framework must be developed in order to systematically address the general characteristics of EISENs. The framework is illustrated using a case study of the synthesis problem of an olefin compression section.
