Online gasoline blending with EPA Complex Model for predicting emissions

Stefan JANAQI, Mériam CHÈBRE, Guillaume PITOLLAT

Frontiers of Engineering Management 2018, Volume 5, Issue 2,   Pages 214-226 doi: 10.15302/J-FEM-2017022

Abstract: Environmental Protection Agency (EPA) is used by refiners to predict the toxic emissions of reformulated gasolinewith respect to gasoline properties.The difficulty in implementing this model in the blending process stems from the implicit definitionimplementation occurred in 2008 and 2010 through the use of generalized disjunctive and mixed-integer nonlinearexecution time of these MINLP models remains prohibitively long to control emissions with our online gasoline

Engineering 2017, Volume 3, Issue 2,   Pages 188-201 doi: 10.1016/J.ENG.2017.02.005

Abstract:

The scheduling of gasoline-blending operations is an important problem in the oil refining industryonly exhibits the combinatorial nature that is intrinsic to scheduling problems, but also non-convex nonlinearbehavior, due to the blending of various materials with different quality properties.global optimization algorithm is proposed to solve a previously published continuous-time mixed-integer nonlinearscheduling model for gasoline blending.

PVDF ultrafiltration membranes of controlled performance via blending PVDF-g-PEGMA copolymer synthesized

Shuai Wang, Tong Li, Chen Chen, Baicang Liu, John C. Crittenden

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 2, doi: 10.1007/s11783-017-0980-0

Abstract: Polyvinylidene fluoride grafted with poly(ethylene glycol) methyl ether methacrylate (PVDF-g-PEGMA) was synthesized using atomic transfer radical polymerization (ATRP) at different reaction times (9 h, 19 h, and 29 h). The corresponding conversion rates were 10%, 20% and 30%, respectively. PVDF was blended with the copolymer mixture containing PVDF-g-PEGMA, solvent and residual PEGMA under different reaction times. In this study, we explored the effect of the copolymer mixture additives with different synthesis times on cast membrane performance. Increasing the reaction time of PVDF-g-PEGMA causes more PVDF-g-PEGMA and less residual PEGMA to be found in the casting solution. Incremental PVDF-g-PEGMA can dramatically increase the viscosity of the casting solution. An overly high viscosity led to a delayed phase inversion, thus hindering PEGMA segments in PVDF-g-PEGMA from migrating to the membrane surface. However, more residual PEGMA contributed to helping more PEGMA segments migrate to the membrane surface. The pure water fluxes of the blended membrane with reaction times of 9 h, 19 h, and 29 h are 5445 L·m ·h , 1068 L·m ·h and 1179 L·m ·h , respectively, at 0.07 MPa. Delayed phase inversion can form smaller surface pore size distributions, thus decreasing the water flux for the membranes with PVDF-g-PEGMA at 19 h and 29 h. Therefore, we can control the membrane pore size distribution by decreasing the reaction time of PVDF-g-PEGMA to obtain a better flux performance. The membrane with PVDF-g-PEGMA at 19 h exhibits the best foulant rejection and cleaning recovery due to its narrow pore size distribution and high surface oxygen content.
