Production Method Sample Clauses
The Production Method clause defines the specific processes, techniques, or standards that must be followed when manufacturing goods or delivering services under a contract. It typically outlines requirements such as the use of certain materials, adherence to industry standards, or compliance with regulatory guidelines. By clearly specifying how products or services are to be produced, this clause ensures consistency, quality control, and helps prevent disputes over whether contractual obligations have been met.
Production Method. Based on previous experiments, it seems that the presence of Ti stabilizes the perovskite structure, which is beneficial for an oxygen carrier. Therefore, it was decided to focus on the production of oxygen carriers based on the C28 composition. Similar to the previous project, the Mn-based oxygen carriers were manufactured using the industrial spray-drying method. This method allows producing oxygen carrier particles with good free-flowing properties, high sphericity and homogeneity on the micro-scale. To produce each small batch, a commercial Mn oxide or ore and Ti oxide, together with Ca(OH)2, and MgO, were weighed and dispersed in deionized water with the necessary organic additives. Then, this suspension was homogenized by an horizontal attrition mill (Netzsch, Germany) prior to spray-drying. During spray-drying, the water based suspension was continuously stirred with a propeller blade mixer while being pumped to the 2-fluid spray-dry nozzle, positioned in the lower cone part of the spray-drier (type 6.3-SD, Niro, Denmark). The suspension is atomized into a large number of small droplets in the chamber of the spray-drier, which is filled with hot air from the top, thus creating a mixed flow regime. As such, the droplets quickly achieve a spherical shape due to surface tension effects. In addition, the large surface-to-volume ratio of the droplets allows rapid water evaporation resulting in dry particles, which are separated from the hot air. After spray-drying, the fraction within the required particle size range (150-300 µm) was separated from the rest of the spray-dried product by sieving. Finally, to obtain oxygen carrier particles with sufficient mechanical strength and with the desired crystalline phases, sintering was performed in air using a high temperature furnace (Entech, Sweden).
