Adaptive multigrid solution strategy for the dynamic simulation of petroleum mixture processes

A simulation of diesel hydrotreating process with real component method

“…(1)Physical property data In order to build mechanistic model with actual physical property for each component involved, real component method is needed, which is more accurate than pseudo-component method in the modeling and simulation [11], and higher accuracy can be expected in industrial practice [11][12][13].…”

Using Wavelets for Solving SMB Separation Process Models

“…Applications of wavelet transformation to the solution of partial differential equation arising in the chemical engineering are limited. – Among those, Cruz, Lim, and Liu exemplified the application on a fixed-bed adsorption model to simulate the propagation of a concentration peak along a chromatographic column with axial dispersion. Application of wavelet technique to the SMB systems has not been found in the open literature.…”

Avaliação do método Wavelet-Galerkin multi-malha para caracterização das propriedades de petróleo e subprodutos.

“…Novas propostas têm sido apresentadas, nas duas últimas décadas, com a finalidade de melhorar a descrição das misturas complexas. Uma delas é o chamado método de discretização adaptativa wavelet-Galerkin (Briesen e Marquardt, 2003, 2004a, 2004b, que utiliza o critério de representação da mistura proposta pela termodinâmica contínua, porém, com algumas variações, (o método está apresentado nos capítulos 4 e 5). Outros são:…”
