This research has introduced a new approach for the numerical simulation of chemical reactions and processes. We call this method as the "Box-Contact" method. The empirical method of numerical simulation usually uses differential equations based on the following assumption；the nature can be expressed as it is continuum and keeping continuity in fields. However especially in the field of material science and engineering, a homogeneous and continuous field can rarely appear. For example, a TV is constructed by various different material parts such as a main frame, switches and a display glass. It suggests that we could not treat the each phenomenal behavior of chemical reactions or processes using differential equations. Because a "TV" phenomenon is processing in the discontinuous field, and can divide simpler distinguished processes. Therefore, we made a concept of "Box-Contact" method in which a phenomenon was divided to kinds of processes and treated as "Boxes". The definition of the "Box" depends on the observational resolution. Each boxes have each simpler processes. Then we associated the "Contact" relations with each boxes to simulate the phenomenon. In this study the adsorption in a separation is demonstrated by using Box-Contact method as an example. The result shows that this method is useful to elucidate the mechanism in the chemical reactive phenomenon, which is not attainable by using ordinary differential equations simulations.
