7. How Is Natural Gas Liquefied For Transportation?
Natural gas is liquefied for transportation through a process called liquefaction, which involves cooling the gas to approximately -260°F (-162°C). This process reduces the volume of the gas by about 600 times, making it easier to transport by tanker.
7.1 Pre-treatment
The first step in the liquefaction process is pre-treatment, which involves removing impurities such as water, carbon dioxide, and sulfur compounds from the natural gas. These impurities can freeze and damage the liquefaction equipment, or they can reduce the efficiency of the process. Pre-treatment typically involves the use of absorption, adsorption, and filtration technologies.
7.2 Cooling
After pre-treatment, the natural gas is cooled to approximately -260°F (-162°C) using a refrigeration cycle. There are several different types of refrigeration cycles used in LNG plants, including cascade cycles, mixed refrigerant cycles, and expander cycles. Each cycle has its own advantages and disadvantages in terms of efficiency, cost, and complexity.
7.3 Storage
Once the natural gas is liquefied, it is stored in insulated tanks at atmospheric pressure. These tanks are designed to prevent the LNG from warming up and vaporizing. The tanks are typically made of steel or concrete and are surrounded by a layer of insulation.
7.4 Loading
The final step in the liquefaction process is loading the LNG onto tankers for transportation. This involves pumping the LNG from the storage tanks into the tanker’s cargo tanks. The tankers are specially designed to transport LNG at cryogenic temperatures.
8. What Are The Different Types Of LNG Tankers?
The different types of LNG tankers include Moss-type tankers, membrane-type tankers, and IHI SPB-type tankers. Moss-type tankers have spherical tanks, while membrane-type tankers use thin membranes to contain the LNG.
