Leakage from pressurized liquid ammonia pipeline has been a serious problem in large commercial cold storages because it might release large amount of liquid ammonia and without safety supervision in daily operations. The present paper shows a…
As natural gas is not uniformly distributed in different regions of the world, and gas tanks are concentrated in specific geographical areas, gas transfer is a key gas-related industry that greatly contributes to the expansion of this energy…
High T c superconducting (HTS) DC cable is a promising solution for large-scale power transmission over long distance. However, the refrigeration system for HTS cable is indispensable but undesirable. Considering that LNG (liquid natural gas) is now…
The conventional process employed for the removal of N2 in a natural gas upgrading facility is cryogenic distillation (CD) and entails a significant investment outlay. Operation of the CD unit occurs at approximately 40bar and 120C, provided by a…
In liquefied natural gas (LNG) production, the total efficiency of the system increased by using mixed refrigerants for the liquefaction process. In this study, the mixing of the effective refrigerants is considered as one of the most important…
The liquefaction process is one of the key technologies of offshore FLNG device and is charged by patent protection of a few companies. Because of special offshore operational environment, the choice of FLNG liquefaction process is different from…
Multi-component refrigerant compression refrigeration cycles have a high coefficient of performance and difficult controllability. In these systems, it is not easily possible to keep the ratio of stream compositions constant in the event of a leak.…
Laval nozzle is the critical part of supersonic separator to provide refrigeration environment. Due to the back pressure at the outlet of supersonic separator in dehydration process, the condensation characteristics of water vapor and the…
Natural gas dew point temperature is a vital quality parameter. The effective control of this specification is important if the natural gas integrity and quality are to be maintained. The present work focuses on improving the dew point and…
Multi-component refrigerant compression refrigeration cycles have a high coefficient of performance and difficult controllability. In these systems, it is not easily possible to keep the ratio of stream compositions constant in the event of a leak.…
Natural gas liquefaction is an expensive process with high energy consumption. Higher mini-LNG capacities have high capital and operating costs meanwhile that will have more product and profit. Therefore, one of the main concerns for the construction…
