A more profitable and efficient way to capture hydro-gen's full value is by capturing and purifying hydrogen from offgas and repurposing it for industrial use. Several recovery technologies are available to do this. Growing demand makes hydrogen recovery a more attractive option. Industry trends, including fuel 1. Conditioning for Rich Gas 2. Cryogenic 3.

This practice is becoming more significant due to increasing LPG demand in some countries and the supply of lighter crudes in countries such as the US. LPG recovery plant was done using Microsoft office excel spreadsheet 2016. 2.2 . I. nlet Feed Parameter . The components of the natural gas feed together with the feed conditions and composition are as follows . 2.2.1 inlet Feed Components List . The components of natural gas feed stream used in this work was selected from Aspen HysisV8.6 As LPG content is increased in the feed gas of a turboexpander-based LPG recovery unit from 10 wt% to 17 wt%, LPG recovery falls significantly (99.1 wt% to 66.8 wt%). A refrigeration system of 16.7 t to 308 t is required to maintain low temperature in the system and also to keep LPG recovery above 99%. GP 3-D model of the Integrated StarLNGL unit. StarLNGL™, the integrated Liquefied Natural Gas (LNG) and Natural Gas Liquids (NGL) technology, uses proven design concepts to enhance LNG production in existing and new NGL recovery plants. As part of the StarLNG™ family, StarLNGL™ builds on Linde's worldwide experience across the entire LNG The purpose of the liquefied petroleum gas (LPG) unit is to process light hydrocarbons (C 1 -C 5) into required component streams.The LPG unit feed streams in a refinery are usually obtained from refinery units such as atmospheric crude distillation, plat former, hydro cracker, and other catalytic processing units. Trimeric Corporation : Trimeric Corporation NGL / LPG RECOVERY TECHNOLOGY Ortloff NGL / LPG recovery technology offers one or more of the following advantages: - Ethane and propane recovery levels up to 99% - Increased recovery with no increase in horsepower - Increased capacity with no increase in horsepower - Lower capital cost - High CO2 tolerance - Improved operational LPG and heaviers present in natural gas Gas cooling in two steps: first at -40°C/35 bar second at -85°C/10,5 bar Main characteristics of the plant: - High percentage of LPG recovery from natural gas thanks to the low temperatures reached in the process; - High plant efficiency due to the adiabatic process of gas expanding in In accordance with the present invention a natural gas stream predominating in methane and containing significant amounts of C 2 , C 3 , C 4 and C 5 and higher molecular weight hydrocarbons is cooled
