“…Total capital cost: The total capital cost of the process, services, and working capital can be obtained by applying multiplying factors or installation factors to the purchase cost of individual items of equipment [41]. The capital cost of the Pd-Ag based membrane and stainless-steel frame is taken from the experimental investigations carried out by US-DOE [42].…”

Model-Based Quality, Exergy, and Economic Analysis of Fluidized Bed Membrane Reactors

In petroleum refineries, naphtha reforming units produce reformate streams and as a by-product, hydrogen (H2). Naphtha reforming units traditionally deployed are designed as packed bed reactors (PBR). However, they are restrained by a high-pressure drop, diffusion limitations in the catalyst, and radial and axial gradients of temperature and concentration. A new design using the fluidized bed reactor (FBR) surpasses the issues of the PBR, whereby the incorporation of the membrane can improve the yield of products by selectively removing hydrogen from the reaction side. In this work, a sequential modular simulation (SMS) approach is adopted to simulate the hydrodynamics of a fluidized bed membrane reactor (FBMR) for catalytic reforming of naphtha in Aspen Plus. The reformer reactor is divided into five sections of plug flow reactors and a continuous stirrer tank reactor with the membrane module to simulate the overall FBMR process. Similarly, a fluidized bed reactor (FBR), without membrane permeation phenomenon, is also modelled in the Aspen Plus environment for a comparative study with FBMR. In FBMR, the continuous elimination of permeated hydrogen enhanced the production of aromatics compound in the reformate stream. Moreover, the exergy and economic analyses were carried out for both FBR and FBMR.

“…The installation factor for the new design is broken down in Table 3 into constituent parts, according to the governing phase being processed. Therefore, for the installation factors, the application and estimation of the total capital cost in the following equation is used [42,43].…”
