    Automation of the Two Stage Biodiesel Production Process
    (2015) Oğuz, Hidayet; Özcan, Muciz; Yağcı, Mustafa; Özkan, Ali Osman
    The control of the biodiesel production plays an important role on achieving the production standard of the biodiesel. The quality of the produced biodiesel depends on the raw materials, alcohol and catalyst selections and process and storage conditions. The control of the biodiesel production not only enables to achieve high quality biodiesel but also maintains the continuity of the product quality. In this work, an automation system for a two stage biodiesel production is designed and realized. A PLC (Programming Logic Control) based system is used for this purpose. The designed and realized biodiesel production facility enables to produce biodiesel using either a single stage or a two stage process. The quality of the biodiesels separately produced using a single stage and a two stage process are analyzed and compared. The analysis results show that a two stage biodiesel production process gives better results compared to the single stage in fuel density, viscosity and flash point

    Design and realization of a welding oscillator
    (2014) Özcan, Muciz
    Welding is one of the most popular methods to combine metal pieces in manufacturing processes. Arc welding, among all welding techniques, is the most commonly used in manufacturing due to its cost and flexibility. During the manufacturing process, arc welding is either performed by an operator or by automatic tools such as welding oscillators. Using automatic tools has advantages over manual use, as the process will be faster, cheaper, and have less welding flaws. In this paper, a homemade welding oscillator and the method to manufacture it are presented. The presented welding oscillator can be manufactured for a very low price compared to those on the market. Moreover, it covers industry-level needs and provides even more functionality with small adjustments if needed by the application. With this work, small-scaled manufacturing foundries will benefit from the price and functionality of the welding oscillator.
