Sour Gas Sweetening with Membrane Technology Membrane technology can be used to separate water vapor, H 2 S, and CO2 at lower concentration levels in natural gas streams, natural gas liquids (NGLs), and liquefied petroleum gas (LPG). 5-6, pp. • The most appropriate feed LPG temperature was determined to be 45 °C. • The optimum MDEA concentration was found to be 35.0 wt%. Petroleum jelly Cosmetics Rust inhibitors and lubricants Cable coating compounds. SWEETENING PROCESSES 1. Thus, Gas sweetening plant is a vital unit in the LNG production route. Petroleum and Coal Pet Coal (2019); 61(3) 517-532 ISSN 1337-7027 an open access journal Article Open Access . A process for the preparation of a halogenated metal phthalocyanine catalyst suitable for sweetening of sour petroleum distillates. Petroleum refining - Petroleum refining - Visbreaking, thermal cracking, and coking: Since World War II the demand for light products (e.g., gasoline, jet, and diesel fuels) has grown, while the requirement for heavy industrial fuel oils has declined. Parametric analysis of sweetening liquefied sour gas was conducted. Moreover, the simulation work is adopted amine gas sweetening process by using DEA solution and it achieved high acid gases removal for instance, H 2 S concentration in sweet gas stream was about 4 ppm at (400 m 3 /h) amine circulation rate. The doctor sweetening process is an industrial chemical process for converting mercaptans in sour gasoline into disulfides. Otto Rotton and William Archer, ‘Deodorizing Petroleum,’ American Artisan and Patent Record (New York), new series 5, (1867), 310. Electrodes and fuel. The invention is protected with 9 international and national patents Choices of a treating method depend on the nature of the petroleum fractions, amount and type of impurities in the fractions to be treated, 711-721. The removal of H 2S from sour oil is called “oil sweetening”. Petroleum and Coal. @ Hydrocarbon streams such as naphtha are treated by the oxidation of mercaptans into disulfide compounds which remain in the hydrocarbon stream. Question is ⇒ In hydrofining catalytic desulphurisation process for sweetening of petroleum products, use of hydrogen, Options are ⇒ (A) enhances the desulphurisation process., (B) minimises coke formation., (C) both (a) and (b)., (D) neither (a) nor (b)., (E) , Leave your comments or … This process continuously injects just a few ppm of caustic into the feed naphtha. HC Petroleum Equipment is high-end solid bed scavenger supplier, which supplies iron sponge as well as complete professionally designed gas sweetening system. Caustic-free Merox for sweetening jet fuels and kerosenes. SWEETENING LIQUEFIED PETROLEUM GAS USING ASPEN HYSYS 3 alkanolamine listed above (Blauwhoff, Lauwhoff, Versteeg, & Vanswaaij, 1984).. Other limitations of MEA include the fact that it is ineffective in removing mercaptan. LPG (liquid petroleum gas) sweetening is a very important refining process in which mercaptans are extracted from LPG by caustic solution, resulting in mercaptide salts. Note this diagram has a trim cooler to control the top temperature of the absorber and a reflux condenser that minimizes the water and MDEA losses via the acid gas stream. Residual fuel oil. Gas Sweetening Units of HC Petroleum Equipment is designed to remove effectively and safely hazardous H2S by employing adsorption process. • Aspen HYSYS version 8.0 was used to simulate the process and verified with DOW's results. Thiols in liquefied petroleum gas are undesirable due to their foul odor and corrosive nature. Petroleum refining or Oil refining is an industrial process in which crude oil is extracted from the ground and transformed and refined into useful products like Liquefied Petroleum Gas (LPG), kerosene, asphalt base, jet fuel, gasoline, heating oil, fuel oils etc. Asphalts. Sour gas contains different concentrations of H. 2. Refinery by-products. Merox Sweetening Process Merox sweetening processes are reserved for heavier hydrocarbons such as kerosene, aviation fuels, and diesel. These sulfur compounds can be removed with the following chemical reactions: W.A.E. Figure 1. STRIPPER IN SWEETENING PROCESS (36 pages with 13 illustrations) This manual includes a description of equipment and procedures to operate and troubleshoot the amine stripper unit. Sulfur compounds darken gasoline, give it an offensive odor and increase toxic sulfur dioxide engine emissions. The conversion is effected during passage of the hydrocarbon and an aqueous stream downward through a cylindrical mass of liquid-liquid contact material (6). In the process of desulfurization, the sulfur containing pollutants are transformed into sulfides and H2S by biological reduction, and the elemental sulfur can be removed via the process of biological oxidation. Treating can be accomplished at an intermediate stage in the refining process, or just before sending the finished product to storage. Therefore, this study aims to simulate the prospective Khurmala gas sweetening process by using the latest version of Aspen HYSYS V.7.3 program. No. However, the solubility of metal phthalocyanine is low in aqueous medium. Contents Introduction Caustic treatment Solutizer process Doctor treating process Copper chloride sweetening Merox process Sulphuric acid treatment Clay treatment Coke. Sulphonates. Mukesh kumar prajapati CSJMA14001390210 2. The process is ideal for lower to mid levels of H 2S concentrations. Figure 1 [7] presents a typical sweetening process flow diagram for the case study. It also has higher utility costs and removes hydrogen sulfide non-selectively. Simplified process flow diagram for an amine sweetening unit [7] Sweetening also reduces concentrations of carbon dioxide. Description of Equipment and Unit Operations The main equipment comprises the following: The Contactor It involves a mass transfer operation (gas/liquid) in which the sour gas Petroleum Science and Technology: Vol. The liquids then flow through a cylindrical screen (8) into an annular separation zone … S and CO. 2; these gases have certain threshold values and a specific standard for their concentration as products of a sweetening process. AND. Since sweetening requires the selective removal of hydrogen sulfide, a tertiary … Metal phthalocyanines are reported to be the most effective sweetening catalyst. Gas Desulfurization Unit consists of inlet gas-liquid separator, process columns fixed adsorbent bed, end gas filters, sampling ports, instruments, valves, safety devices, operator platforms, and other components specified in HC’s proposal. In the Gas Sweetening process, the sour contents present in the feed natural gas are removed by chemical absorption technique. Cov Hydrocarbon sweetening and treating processes Many products, such as thermal naphthas from visbreaking, coking or thermal cracking, and high-sulphur naphthas and distillates from crude-oil distillation , require treating in order to be used in gasoline and fuel oil blends. The process of removing these thiols is termed as sweetening. As more LPG's (liquefied petroleum gas) are being produced, the demand for liquid hydrocarbon sweetening facilities has increased. Subsequently, these mercaptides are oxidized in the presence of air and catalyst to disulphides … The basic data for its optimization are not present in the literature, however, recently published performance data of an Iranian refinery filled this gap to some extent.
