“…As a result, the stream formed when rising vapor in the column comes into contact with it and can dramatically absorb ethane components from the vapor. This improves the level of recovery in the GSP process system [63,64].…”

A comprehensive review is presented on the natural gas liquid (NGL) recovery process with emphasis on process description, energy requirements, NGL production, operating cost, and propane recovery. The industry standard single-stage (ISS), recycle split vapor (RSV), cold residue reflux (CRR), and gas subcooled process (GSP) technologies focus on the improvement in the rectifying section of the demethanizer column, while the enhanced NGL recovery process (IPSI) focuses on the stripping section of the column. The fluor process consists of an absorber, a scrub column, and heavy hydrocarbon (HHC) separator, which form the integrated process of liquification and NGL separation. For rich feed, the economic performance, payback, and total annualized cost (TAC) of the IPSI process were lower than the other processes. For lean feed, the results of the scrub column scheme demonstrate the finest economic performance.

“…Jiang et al, [16] performed the CEA method on China's ethane recovery processes based on rich gas. Hu et al, [17] studied NGL plant equipment and found that air cooler contributed to the highest exergy destruction. Meanwhile, a new analysis method called as advanced exergy analysis (AEA) was employed in recent years to provide useful information for identifying system behavior [18].…”

Energy quality in each country is one of the important indicators of economic development, Which affects the economic growth of that country. Exergy analysis, considering all flow properties including pressure, temperature, composition, is a powerful way to evaluate the energy consumption of equipment such as natural gas and liquefied gas plants. Inefficiency of a system can be defined by the conventional exergy analysis method, While, irreversible resources and real potentials for system improvement can only be identified by the advanced exergy analysis method. This analysis splits conventional exergy destruction into two exogenous and endogenous parts according to origin, and also unavoidable and avoidable parts according to the ability to remove and modifications. In this method, the exergy concept was separated by considering the ideal and avoidable condition assumptions. As a real case study, a natural gas liquid plant 800, from National Iranian South Oil Company located in southwest of Iran was considered to be investigated by conventional exergy analysis, advanced exergy analysis methods. The results of conventional exergy analysis illustrated that the highest amount of exergy destruction belonged to compressor and heat exchanger with 509.99 and 629.04 kW, respectively. However, in the case of heat exchanger, despite having the highest rate of exergy destruction, it is not considered in modification priorities due to its low avoidable exergy destruction value. Also, advanced exergy analysis suggested that the exergy destruction of the compressor and heat exchanger will be reduced by improving performance of these components.

“…Due to increased globalization and urbanization, the energy resources are depleting rapidly. There is a massive increase in the per capita energy consumption and results in the increase in global energy demand; hence, dependence on the low-carbon and environment-friendly fuel is increasing (Hu et al, 2019). One of the clean energy resources is natural gas, which is a mixture of methane, ethane, propane, butane, and heavier hydrocarbons.…”

“…The specific impact on the turbo expander for optimal NGL recovery, feed compositions on different process schemes, gas subcooled, recycle vapor split, and cold residue has also been reported (Getu et al, 2013). The exergy analysis of the NGL recovery processes through modelling and simulation in Aspen HYSYS indicated that most of the exergy destruction happens at the air cooler and column present in the flowsheet (Hu et al, 2019). The exergy destruction in the LPG production process happens at the fractionation columns (Saadi et al, 2019).…”

Liquefied petroleum gas is an alternative, relatively clean and a supreme source of energy, which is being used as a key component in the global energy supply. The international trade agreements and the chemical and non-chemical demand of liquefied petroleum gas with the increase in the world’s population have brought its production from the processing of natural gas to the limelight. During its processing, a variety of different components are extracted from it, including methane and ethane which remains in the bulk as natural gas. The objective of this research work is to find the capability of investigating the liquefied petroleum gas recovery performance to make the process economical by saving the processing cost and energy. The novelty of this work is to deal with the design and simulation of a liquefied petroleum gas plant using Aspen HYSYS. To make this process energy efficient and economical, different schemes of process alternatives were applied by reducing the sizes of the exchanger and other pieces of equipment. Three cases are studied in which feed is precooled by rerouting the stream and/or by repositioning of the chiller for the recovery of liquefied petroleum gas from natural gas by analyzing their cost and process parameters. The modelling and simulation base case and three different case studies are realized in Aspen HYSYS. It has been observed that case study 2 results in about 10% increase in LPG production where the chiller is repositioned in the separation section of the LPG production flowsheet. Case study 3 shows a maximum decrease in hot side utilities in the flowsheet of about 20% while 10 and 14% decreases are observed for case studies 1 and 2, respectively. Furthermore, economic analysis indicates about 18 and 22% in the capital cost for case studies 2 and 3, respectively, due to the lower size of process units. The outcome of this investigation is to present plenty of suggestions to improve the process efficiency and minimize the requirement to over design the plant components.
