Experience has shown that there is a relationship between demand and price, contrary to the short-term mode, which is expected to be inverted between price and value, and the effects of lowering and rising prices follow reverse. But symmetric results; in the long run, there may be unlawful...

With only half of the carbon footprint of coal, natural gas is widely considered to be an important transition fuel as the world economy shifts away from more carbon-intensive energy sources towards lower-carbon alternatives. Liquefied natural gas (LNG) has accordingly grown as a solution for...

Small-scale production of liquefied natural gas (SS LNG) is a promising, but little-known direction of the gas industry development, which is aimed at meeting the needs for environmentally friendly decentralized energy supply of nearby regions. In this study, an economic efficiency of four...

This article considers a process technology based on absorption for CO2 capturing of ethane gas in phase 9 and 10 of south pars in Iran using diethanolamine (DEA) as absorbent solvent. This CO2 capture plant was designed to achieve 85% CO2 recovery and obtain 19 ppm the CO2 concentration in the...

It has been an important objective in China's energy development strategy to accelerate the promotion of natural gas utilization, cultivate main sources of natural gas, and increase the proportion of natural gas consumption. Based on the analysis of the development of natural gas utilization in...

Dehydration using triethylene glycol (TEG) is widely used in natural gas processing to avoid corrosion and plugging of the flow lines. Optimization using Aspen HYSYS simulator and optimizer tool was performed to minimize the processing cost considering different sets of parameters: TEG...

A growing number of major natural gas markets in the world have adopted the gas-on-gas competition, or are in the phase of transition to this price formation mechanism. In this situation, China has also started to reform the pricing mechanism by establishing gas trading centers in Shanghai and...

Underground gas storage (henceforth; UGS) is considered as a common method which resolves the seasonality problem of transportation and distribution of gas phase in the oil and gas industries. The main objective of this study is to simulate one of Iranian's depleted gas condensate reservoir and...

This work presents the synthesis gas production from gasification of plastic waste, i.e. polyethylene (PE) and polypropylene (PP). The steam gasification is modeled by using AspenPlusTM simulation software. The effects of gasifier temperature and steam to feed (S/F) mass ratio were examined to...

With the continued downturn in global crude oil prices, the natural gas market shows a rapid growth trend. The coordination of natural gas trade is becoming more and more important, and many organizations have put forward natural gas energy metering the schemes. Nowadays, the energy metering...
