SMCC Group provides advanced modern solutions for the reliability, availability, economy, and environmental sustainability of existing equipment. In addition, our modern solutions are tailored to your specific equipment. Our transformation concept includes not only the core machine itself, but also the requirements for auxiliary systems, instruments, and control equipment.


1. Fuel Conversion

We offer a range of tailor-made modern solutions to keep your equipment up-to-date. Do you want to upgrade your engine? We offer modifications to existing diesel engines that make it easier for our customers to enjoy the benefits of natural gas as a fuel. Our upgrade ensures a return on investment for our customers.

With changes in fuel prices and availability, changing the fuel of the prime mover can make it more economical, or one can choose to switch fuel types. Although fuel conversion is a major project, we have the support of long-term experience. Our transformation concept can help you reduce equipment downtime and improve the overall profitability of your business.


2. Monitoring and Control

In recent years, diesel engine technology has been advancing, but upgrading our engines can bring benefits from new technologies, including advanced monitoring and control systems to improve safety and optimize engine performance.


3. Fuel and Lubricant Conservation

In the modern shipping industry, the consumption of fuel and lubricants is the largest expense. Through cutting-edge design technology, we can minimize your engine oil consumption and maximize your return on investment, making your vessel more efficient. This includes the modification of alpha lubricators and turbochargers as required, as well as customized deceleration.



4. Reducing Emissions Means Lowering Exhaust Gas Emissions. 

Pollutant reduction is an important means to adjust economic structure, transform development mode, improve environmental quality, and solve regional environmental problems. In recent years, regulations regarding exhaust emissions from internal combustion engines have become increasingly strict at both regional and global levels.

These regulations mainly focus on:

Nitrogen oxides (NOx)

Hydrocarbons (HC)

Sulfur oxides (SOx)

Particulate matter (PM)

 

Regarding emissions and their monitoring, SMCC Group has developed power plant related technologies to ensure full compliance with emission reduction regulations.

 

4.1. Selective Catalytic Reduction (SCR)

Selective catalytic reduction is the most effective way to reduce nitrogen oxide emissions. After catalytic treatment, the harmful NOx in the exhaust gas is decomposed into harmless nitrogen and water. Injecting a reducing agent (such as NH3, liquid ammonia, urea, or other nitrogen-containing compounds) into the exhaust stream upstream of the catalytic reactor, together with the catalyst, causes the decomposition of nitrogen oxides.

By using SCR, the engine can operate at partial, full load, and maximum efficiency, and a NOx reduction rate of up to 97% can be achieved with this technology.

 

4.2. Oxidation Catalysts

When using low sulfur fuel (gas or liquid) combinations of carbon monoxide, hydrocarbons, or formaldehyde, good thermal efficiency and/or emission limitations are required, and oxidation catalysts are the key to success.

According to different requirements, we will use different coating catalyst systems to select the best oxidation catalyst for you in terms of functionality and price. When the catalyst needs to be cleaned or replaced, the monitoring system will sound an alarm. If necessary, oxidation catalysts can be easily combined with SCR systems.

 

4.3. Desulfurization

The emissions of sulfur oxides are caused by the sulfur content in the fuel and are not related to the engine. Any sulfur burned during the combustion process will produce sulfur oxides. Low sulfur fuels are usually expensive and not always available, and desulfurization costs can be high. Appropriate technology must be adopted to remove sulfur from exhaust gas to meet different emission restrictions.

There are currently two methods:

Traditional domestic hydrated lime desulfurization method.

Sodium carbonate drying desulfurization method.

The selection of appropriate desulfurization methods mainly depends on the availability of water and absorbent.

 

4.4. Particulate Matter (PM)

According to the ash content and combustion characteristics of the fuel, particulate emissions are mainly generated in heavy oil applications. The following two different systems can further reduce the emissions of these already low particulate matter:

4.4.1. Passive regeneration exhaust purifier

For the treatment of exhaust emissions from internal combustion engines, the DOC+CDPF technology solution is the best choice.

4.4.2. Electrostatic precipitator (ESP)

In applications with high exhaust temperatures, utilizing the electrostatic attraction of electric ions for filtration is the best choice.

4.4.3. Bag filtration

Bag filters are suitable for low exhaust temperatures, such as in cogeneration applications. If necessary, these can be easily combined with desulfurization systems.

 

4.5. Emission Monitoring

To comply with local regulations on exhaust emissions and ensure the ideal operation of exhaust treatment equipment, we will choose the best solution for your price and actual needs. The functionality and reliability of these systems have been proven.



5. Noise Reduction

When the generator is running, the noise level generated by the unit itself is 90-140 decibels. For the benefit of customers, eliminating the noise hazards caused by the operation of the generator unit is beneficial to the physical and mental health of your staff, creating a peaceful and quiet working environment, and improving work efficiency. It is recommended that you adopt a comprehensive noise control project.

 

5.1. Design Principles

Based on the current situation of the computer room, we plan to design it using sound insulation, sound absorption, and noise reduction methods. By improving the airtightness of the computer room and installing fire-resistant soundproof doors, we aim to control noise within the room; To ensure the need for combustion air during the operation of the generator, design intake and exhaust ducts and conduct sound absorption treatment; In order to prevent the heat generated during the operation of the generator from causing an increase in the temperature of the machine room and affecting the normal operation of the generator, an exhaust axial flow fan is installed to ensure smooth indoor air convection and maintain stable temperature and pressure balance in the machine room; Install a secondary muffler in the exhaust pipe to reduce noise in the exhaust gas and achieve better treatment effects.

 

5.2. Governance Measures

5.2.1 Enclosed computer room, design a soundproof room and install fireproof soundproof doors to enhance its sealing and sound insulation effect, and control noise inside the computer room.

5.2.2 Set up air intake and exhaust ducts, and lay sound-absorbing cotton blankets on the inner walls of the ducts; Install a composite sound-absorbing block in the center of the channel for sound absorption treatment, which greatly attenuates the external noise after the noise is absorbed through the channel.

5.2.3 Install a secondary muffler on the exhaust pipe and perform noise reduction treatment on the exhaust pipe.
