In addition, the LNG production process also generates by-products such as natural gas liquids (NGLs) and helium. These by-products have various industrial applications and can be separated from the LNG during the liquefaction process. Overall, the LNG process flow diagram involves several stages,...

Natural gas, or other products obtained in the liquefaction plant, is the primary source employed to start the liquefaction process. The LNG energy content is notable; therefore, the recovery of a part of the energy in the regasification process is reasonable. Frequently, this energy is not ...
Especially, a natural liquefaction process in a LNG-FPSO, which liquefies the processed natural gas to store in a storage tank of a LNG-FPSO, is the most important process in terms of cost and risk. In the situation the most of ongoing or prospective projects for LNG-FPSO adopt dual ...
In order to meet customers specifications and prevent damage to liquefaction equipment, plant inlet gas would go through a series of pre-treatment steps. Figure 2 is a block flow diagram of a typical 2-train LNG plant showing these pre-treatme 27、nt steps.Figure 2 LNG plant block flow ...
Liquefaction Plants1 Including Myanmar which has stopped importing LNG as of 20212 Includes Yemen and Libya,although Yemen LNG and Marsa EI Brega LNG have suspended operations,this number excludes the liquefaction capacity of Kenai LNG,which has announced plans to be converted to an import terminal....
The suggested processes are composed of following four steps: LNG regasification process, natural gas combined cycle (NGCC), CO2 capture process and CO2 liquefaction process. Download: Download high-res image (502KB) Download: Download full-size image Fig. 1. Simplified diagram of the proposed ...
Fig. 1 The process of natural gas liquefaction 天然气的可燃性和液化后的体积急剧减小, 且温度很低。这样的特征使得 LNG 的储罐要求 首先有较好的低温韧性、热膨胀系数较小。储存 LNG 时要全面考虑安全问题、经济和占地面积等。 其储罐的管道必须符合ASME 要求,且必须为双壁 ...
