Summary
Maritime trade
Area of Science:
- Environmental Science
- Marine Engineering
- Chemical Engineering
Background:
- Rapid growth in maritime trade generates significant ship emissions, including nitrogen oxides (NOx), sulfur oxides (SOx), carbon dioxide (CO2), and particulate matter (PM).
- These emissions pose severe risks to environmental quality and human health.
- International Maritime Organization (IMO) and governmental regulations are increasingly stringent, necessitating cleaner shipping solutions.
Purpose of the Study:
- To comprehensively review the environmental and health impacts of ship emissions.
- To examine new international regulations concerning ship exhaust.
- To analyze the application, principles, and challenges of clean energy sources and exhaust control technologies in the shipping industry.
Main Methods:
- Literature review of existing research on ship emissions.
- Analysis of environmental and health impacts of specific pollutants (NOx, SOx, CO2, PM).
- Evaluation of clean energy alternatives (LNG, biodiesel, methanol, hydrogen, ammonia) and after-treatment technologies (SCR, EGR).
Main Results:
- Ship emissions (NOx, SOx, CO2, PM) have detrimental effects on ecosystems and public health.
- New regulations are driving innovation in emission reduction technologies.
- Clean energy sources and advanced exhaust treatment systems show promise but face implementation hurdles.
Conclusions:
- The shipping industry must adopt clean energy and advanced emission control technologies to mitigate environmental damage and comply with regulations.
- Further research into the principles, applications, and obstacles of these technologies is crucial for effective emission reduction.
- Addressing ship emissions is vital for sustainable maritime trade and global environmental health.

Maintaining optimal conditions within fermenters is essential for maximizing microbial productivity and ensuring process efficiency. This lesson focuses on key parameters—temperature, foam, pH, carbon dioxide, oxygen, and pressure—and their precise measurement and control strategies in fermentation systems.Temperature ControlTemperature regulation is critical due to the exothermic nature of many fermentation processes. In small laboratory fermenters, temperature is commonly monitored using...

In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the fermentor via a sparger...
