| Exchange plate | Chemical Industry | In oil refineries, the most commonly used distillation column internal is the tray. This is a horizontal plate covering the whole column cross-section, except for the "downcomers. " The plate is perforated to allow passage of gas. In operation, liquid flows on the tray from a downcomer and into a highly turbulent froth made by bubbling and jetting of gas from the perforations. The froth is held on the tray for a short time by the weir, then flows over into another downcomer. (1). Source: European Union. (references) | |
