Black and white cross-section diagram of an OlivAir Staged Packed-Bed Reactor with three filtration stages and labeled inlet/outlet.

Create a black-and-white vector-style technical schematic intended for a peer-reviewed chemical engineering research paper. The figure should resemble a professional reactor diagram typical of journals such as Chemical Engineering Journal or AIChE Journal, with clean engineering linework, consistent thin line weights, and a minimal monochrome appearance on a white background. Avoid artistic shading, sketch styles, gradients, or decorative effects. The diagram should show a vertical cylindrical packed-bed reactor titled “OlivAir Staged Packed-Bed Reactor.” The reactor should be drawn in cross-section with transparent side walls so that the internal structure and packed layers are visible. At the top of the reactor, include a short horizontal inlet pipe entering the lid, followed by a clear downward flow arrow entering the column. Label this inlet line “Acidic influent (pH 1–4)” and optionally note that the stream represents acidic wastewater entering the system. Inside the column, draw three stacked packed-bed layers separated by thin horizontal perforated support plates. The top packed layer should be labeled “Stage 1 – Ca-silicate slag” and illustrated with large angular rock fragments to represent coarse reactive slag particles. The middle packed layer should be labeled “Stage 2 – Crushed olivine” and illustrated with medium-sized irregular crushed particles smaller than the slag above. The bottom packed layer should be labeled “Stage 3 – Carbonate polishing / filtration Ver más
