Small Unit Operations refer to the fundamental processes used in various industries, particularly in chemical engineering and manufacturing. These operations involve the handling and processing of small quantities of materials, allowing for efficient experimentation, production, and quality control. Common examples include mixing, heating, and separating substances on a smaller scale. These operations are essential for developing new products and optimizing existing processes. By focusing on small units, companies can reduce costs, minimize waste, and enhance safety. This approach is particularly useful in pharmaceuticals, where precise formulations are critical for effective medications.
