“…Among such applications are steam 22−24 and autothermal 25 methane reforming, both for H 2 production, dry reforming of methane with carbon dioxide, 26 dehydrogenation reactions of cyclohexane, 27,28 ethylbenzene to produce styrene, 29,30 and benzene. 31 A report on modeling of Pd-based MRs for WGS and steam methane reforming (SMR) can be found in ref 32. Also, an overview on modeling of catalytic MRs for several applications is presented in ref 33 (Chapter 5).…”

This paper investigates the alternative of precombustion capture of carbon dioxide from integrated gasification combined cycle (IGCC) plants using membrane reactors equipped with H 2 -selective zeolite membranes for the water gas shift reaction. Specifically, a one-dimensional and isothermal membrane reactor model is developed. This model is used for simulation and optimization studies considering cocurrent and countercurrent modes of reactor operation. The simulation results indicate successful countercurrent cases that satisfy all of the specified targets and constraints. With use of this developed model, a novel optimization problem is formulated and solved to guide the selection of the optimal reactor design among typical scenarios of operation. The optimization results suggest as optimal solution a reactor design with a preshift followed by a membrane reactor. The obtained optimal design enables a more efficient membrane use by placing it in the optimal location. This design also results in savings of as high as 25% (in the range of 10−25%) in terms of membrane material when compared to the original membrane reactor design. For the price range of zeolite membranes considered on the order of $1000−10 000/m 2 and for large-scale applications, in which the membrane surface areas are on the order of 2000 m 2 , 25% of savings implies cost reductions on the order of millions of dollars (as high as $5 000 000 in this case).

“…For collocation points of odd numbers (N = 5, N = 15) as indicated in symmetrical system. The selection of even functions used for the trial functions was essential because a selection of odd functions might lead to a zero value for the multiplicative coefficient (Tayakout et al, 1995). The number of 10 collocation points was found to be sufficient in this work.…”

“…Orthogonal collocation is one of the widely used collocation methods for solving many chemical engineering problems (Rice and Do, 1995;Tayakout et al, 1995;Mehdizadeh and Dickson, 1990). Collocation methods have been found to be a powerful numerical problem-solving method of weighted residuals for engineering and science applications.…”

“…The mathematical model expressed by a system of parabolic non-linear partial differential equations was solved numerically by a finite element method using the Lagrange polynomial approximations of arbitrary degree in each of the finite elements, which the interior nodes were optimized as in the orthogonal collocation method (OCMFE) [7][8][9]. The basic idea of the OCMFE technique, as its name applies, is based on introduction of fixed elements or breakpoints fx i g NEþ1 i¼1 within the integration interval (x 1 , x NE+1 ), thus forming subdomains.…”
