“…Due to self-refrigeration, the requirement for propane refrigeration is reduced. But there are some limitations in terms of the increase in plant capacity and for richer feed added refrigeration is required to sustain a good NGL recovery [60].…”

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.

“…The stabilized condensate is provided into de-butanizer tower to remove the LPG from the top of the tower, and remaining condensate is stored in condensate storage tanks. Another LPG absorption tower has been added to remove LPG from the slug catcher overhead gas with cooled condensate (Liu et al 2015). The performance of LPG recovery units could be improved by selecting the optimal operating conditions (Bahmani et al 2017).…”

Liquefied petroleum gas (LPG) becomes popular in the twentieth century as source of energy, since it is economically feasible to be produced, transported, sold and stored as a liquid fuel. LPG in Egypt is considered one of the most important domestic fuels. Egypt imports half of its LPG fuel demand. Many researches have been developed to increase the production of LPG in Egypt by increasing the productivity of the refineries. The objective of this study is to investigate the possibility of adding other relatively volatile hydrocarbons as ethane, n-pentane and pentanes’ isomers (iso-pentane and neo-pentane) and/or utilizing relatively volatile oxi-hydrocarbons [mainly dimethyl ether (DME) or dimethyl propane (DMP)] to increase LPG production without affecting its specifications, in order to reduce the import gap of LPG in Egypt. The new LPG mixture is adjusted to meet the Egyptian specifications of LPG (2020). Due to ethane critical properties, it is recommended not to add ethane to LPG since the behavior of ethane cannot be predicted at 50 °C and will be separated inside the LPG bottle. In addition, it will necessitate the increase in LPG butane content. In summer, it is recommended to add i-C5 or 2,2DMP or a mixture of both to LPG (depending on the cost). In winter, it is recommended to add 2,2DMP or a mixture of 2,2DMP with i-C5 to LPG (depending on the cost). Adding DME to LPG with any percentage will decrease the heating value below the Egyptian heating value specifications (2020). Adding neo-pentane to LPG is more preferable than DME, since the heating value of neo-pentane is higher than that of DME. Also, the production cost of the neo-pentane is lower than that of DME.

“…Raw natural gas is a source of dry natural gas; its variant natural gas liquids (NGLs), termed as natural gas condensates, contain sulfur and liquefied petroleum gas. In engineering context, butane and mere propane are designated as liquefied petroleum gas (LPG) (Liu et al, 2015;Faramawy et al, 2016). LPG is extracted from natural gas and is applied as fuel for multi purposes by providing energy to the vehicles and for cooking and heating appliances, and it is used as a refrigerant and aerosol propellant, thus hindering the damage of the ozone layer (Arteconi et al, 2010;Raslavičius et al, 2014;Hao et al, 2016).…”

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.
