Abstract:
Microalgae have lately been discussed whether they can serve as a renewable energy source in the future. To achieve this goal, the aim of our experiment is to optimize open pond system. The energy input of a process should be minimized to ensure a positive energy balance as basic requirement.Microalgae growth is highly affected by temperature. The difficulty to control the transient conditions of temperature in outdoor cultivation makes it essential to predict the relationship between temperature and microalgae growth. An accurate temperature model plays a significant role in the design of an efficient cultivation system. A temperature model at specified operating conditions is derived and validated using experimental data. The cultures are allowed to grow under sufficient nutrient conditions and continuous light for an adequate period of time to observe the growth cycle at different temperatures. Previous publications utilise a combination of the Arrhenius equation and Monod growth model to derive a kinetic model based on temperature and a limiting nutrient. In addition, the temperature model aids in carrying out the energy balance of the entire microalgae system and consequently, to assess the feasibility of the project. Microalgae growth in outdoor conditions will differ from the laboratory results due to uncontrolled environmental conditions, however the laboratory scale model should still give a close estimate of the conditions of the system. Benefits of such model include realistic design of raceway ponds that produce the desired amount of biodiesel cost efficiently.
