Marine processes are more challenging due to harsh environmental conditions, strict regulations, and the need for efficient use of space and energy. Static mixers, are ideal in marine and offshore settings because they offer reliable, maintenance-free solutions for essential tasks such as water treatment, fuel optimisation, and emissions control. Their ability to evenly blend fluids ensures compliance, operational efficiency, and reduced environmental impact in demanding marine environments.
Ballast water is used in ships to maintain stability, but it often contains invasive marine species that, when discharged, can wreak havoc on fragile ecosystems. Static mixers play an essential role in ballast water treatment systems by ensuring that treatment chemicals, such as chlorine or other biocides, are uniformly dispersed throughout the water. By ensuring the even distribution of chemicals, static mixers help to neutralise potentially harmful organisms, preventing ecological harm when the water is released back into the ocean.
Marine vessels, which spend extended periods away from land, need clean water for drinking and effective wastewater disposal, so static mixers are commonly utilised in both processes. In drinking water systems, static mixers help to blend disinfectants, such as chlorine or UV treatment chemicals, into water to purify it for human consumption. Similarly, in sewage treatment processes, static mixers assist in the effective distribution of chemicals to break down waste or neutralise harmful bacteria, ensuring the treated water meets environmental regulations before being discharged into the sea.
Produced water, which emerges as a byproduct during oil and gas extraction on marine vessels, often contains oil, heavy metals, and other pollutants. Static mixers are used to inject chemicals that separate contaminants from the water, making it easier to meet discharge standards. By thoroughly mixing these chemicals, enhanced efficiency in treatment processes is achieved, thereby reducing the environmental impact.
Static mixers are integral to Selective Catalytic Reduction (SCR) processes, particularly to control air pollution on ships. In systems such as DeNOx and DeSOx, which reduce nitrogen oxides (NOx) and sulphur oxides (SOx) emissions, static mixers ensure that the reducing agents - ammonia for NOx or water for Sox - are uniformly distributed within the exhaust gas. This maximises the efficiency of the SCR catalyst and reduces harmful emissions.
Another key application of static mixers is in fuel systems in which additives are blended into marine fuel to enhance its performance or reduce emissions. By ensuring that additives are thoroughly dispersed, static mixers optimise fuel combustion and reduce engine wear which, in turn, enhances fuel efficiency and reduces operating costs.
