การดัดแปลงกระบวนการแยกอากาศเป็นกระบวนการผลิตก๊าซธรรมชาติเหลว / เสาวลักษณ์ ธนะภาชน์ = Modification of air separation process to liquefied natural gas process / Saowaluk Thanaphat
To investigate of air separation process and liquefied natural gas (LNG) production, as both of two manufacturing processes are using similar technology to manufacture and products of both processes are in cryogenic condition, base on these knowledge bring to the study to apply some machine and equipment to apply in the liquefied natural gas production. The study is to compare the condition of two processes by PRO II program to create the model and simulate. Also use the created model to selecting the device from air separation process then apply in liquefied natural gas production process. The results of the comparison of the two conditions found in most of the plate–fin heat exchanger with similar conditions. When the heat duty 28.89 M.kJ/hr. The plate–fin heat exchanger air separation process. To be adapted for use with liquefied natural gas production. The natural gas from Western sources of supply LNG productivity is the most 23,851.2 kg/hr. The amount of energy produced per unit mass of LNG production is minimal 1,204.4 kJ/kg of LNG. The refrigeration work for LNG production varied inversely with the pressure of LNG produced.
