Micro and Mini Biomethane or Natural Gas Liquefaction Plant

 

Thanks to the wide experience and know-how gathered in cryogenic technologies, SIAD Macchine Impianti has developed a wide range of natural gas liquefaction plant.

 

Zero-km natural gas liquefaction plant

 

SMART LNG plant are the first solution developed in Italy for the liquefaction of natural gas (LNG) on a small and scale.

The gas produced in this way can be used locally in transport service stations or for micro-distribution networks. SIAD Macchine Impianti uses tested and proven technologies characterized by easy plant start up, operation and shutdown, but also involving highly reliable and efficient nitrogen-handling machines (turbines and compressors).

The plant is also performing with high-pressure, natural gas network and its liquefaction process is flexible, so that a variation in capacity is straightforward and continuous operation is possible.

All this without sacrifying safety, by using nitrogen (inert gas) instead of hydrocarbon as a refrigerant.

 

The supply of natural gas liquefaction plant

 

Natural gas at ambient pressure liquefies at -162°C, a temperature that can be reached only using cryogenic technology, widely proven by SIAD Macchine Impianti.

SMART LNG natural gas liquefaction plant in the first pre-treatment stage remove contaminants from natural gas, such as water, hydrogen sulphide, heavy hydrocarbons, carbon dioxide and ammonia.

The next phase is liquefaction, implemented through a heat exchanger, which benefits from the frigories released by the evaporation of liquid nitrogen.

If liquid nitrogen is not available, a nitrogen recycle process comprising compressors and turbines is used.

The most important features of Smart LNG involve four key aspects of SIAD Macchine Impianti’s engineering skills: namely, robust and consolidated cryogenic technology, a flexible liquefaction process, operational safety and maximum environmental sustainability.

We offer the following engineering services:

• Feasibility studies.
• Commissioning supervision.
• Erection, start up and performance testing.
• Remote control.
• Software for process simulation.

SMART LNG plant is the first and only system solution developed in Italy for the liquefaction of natural gas (LNG) on small and medium scales. The LNG produced in this way can be used locally in filling stations for vehicles or for micro-distribution systems.

• Cold gases transport & storage

SIAD Macchine Impianti offers a wide range of solutions and can satisfy your requirements with products and services that respond to your specific needs.
