Natural gas is valuable both as a clean source of energy and as a chemical feedstock. Before reaching the customer, it has to pass several processing steps. These steps are partly neces- sary to be able to transport the gas over long distances and partly necessary for the recovery of valuable components contained in the gas. Linde AG´s Engineering Division has world-class experience in the entire natural gas processing chain. Linde offers engi- neering as well as technical and commercial services, includ- ing feasibility studies, pre-FEED, FEED, detail engineering and turnkey plant construction. Plant design and scope of supply typically includes specialized and tailor made cryogenic equipment manufactured in Linde workshops such as plate- fin and coil-wound heat exchangers. Linde´s competence in project development, planning, exe- cution and construction of turn-key plants is clearly demon- strated by the fact that it has built more than 4,000 plants world-wide. 4 Components and pretreatment of natural gas. Components of natural gas Pretreatment of natural gas Natural gas is a mixture of gases containing Natural gas pretreatment typically consists of primarily hydrocarbon gases. It is colorless and mercury removal, gas sweetening and drying. -
Naphtha Catalytic Cracking Process Economics Program Report 29K
` IHS CHEMICAL Naphtha Catalytic Cracking Process Economics Program Report 29K December 2017 ihs.com PEP Report 29K Naphtha Catalytic Cracking Michael Arne Research Director, Emerging Technologies IHS Chemical | PEP Report 29K Naphtha Catalytic Cracking PEP Report 29K Naphtha Catalytic Cracking Michael Arne, Research Director, Emerging Technologies Abstract Ethylene is the world’s most important petrochemical, and steam cracking is by far the dominant method of production. In recent years, several economic trends have arisen that have motivated producers to examine alternative means for the cracking of hydrocarbons. Propylene demand is growing faster than ethylene demand, a trend that is expected to continue for the foreseeable future. Hydraulic fracturing in the United States has led to an oversupply of liquefied petroleum gas (LPG) which, in turn, has led to low ethane prices and a shift in olefin feedstock from naphtha to ethane. This shift to ethane has led to a relative reduction in the production of propylene. Conventional steam cracking of naphtha is limited by the kinetic behavior of the pyrolysis reactions to a propylene-to-ethylene ratio of 0.6–0.7. These trends have led producers to search for alternative ways to produce propylene. Several of these— propane dehydrogenation and metathesis, for example—have seen large numbers of newly constructed plants in recent years. Another avenue producers have examined is fluid catalytic cracking (FCC). FCC is the world’s second largest source of propylene. This propylene is essentially a byproduct of refinery gasoline production. However, in recent years, an effort has been made to increase ethylene and propylene yields to the point that these light olefins become the primary products. -

Cracking (Chemistry)
Cracking (chemistry) In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkenes. Simply put, hydrocarbon cracking is the process of breaking a long chain of hydrocarbons into short ones. This process requires high temperatures.[1] More loosely, outside the field of petroleum chemistry, the term "cracking" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG.

High selectivity towards olefins is usually hindered by numerous side reactions in a conventional crack- ing/pyrolysis technology. Herein, we show recent studies devoted to selective ethylene production via oxidative and non-oxidative reactions. This review summarizes the progress that has been achieved with ethane conversion in terms of the process effectivity. Briefly, steam cracking, catalytic dehydrogenation, oxidative dehydrogenation (with CO2/O2), membrane technology, and chemical looping are reviewed.

5.1 OVERVIEW Gasoline Is a Mixture of Relatively Volatile Hydrocarbons
GASOLINE 117 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW Gasoline is a mixture of relatively volatile hydrocarbons, including alkanes, cycloalkanes, alkenes, and aromatics. Individual hydrocarbon components differentially partition to environmental media on the basis of their physical/chemical properties. Gasoline is released to the atmosphere as hydrocarbon vapors from processing and use as a fuel, and to surface water, groundwater, and soil through spills and leaks in aboveground and underground storage tanks and pipelines. Gasoline has been identified in 23 of the 1,397 NPL hazardous waste sites that have been proposed for inclusion on the NPL (HAZDAT 1992). The frequency of these sites within the Unites States can be seen in Figure 5-l. The volatile hydrocarbon fraction of gasoline, which consists primarily of short-chain (C4-C5) alkanes and alkenes and some aromatics, partitions to the atmosphere where photochemical oxidation is the main removal process. Much of what is released to surface waters and surface soils is lost by volatilization to the atmosphere. Releases to subsurface soils may leach through the unsaturated zone and contaminate groundwater. Aromatics constitute most of the water soluble fraction of gasoline. Biodegradation of gasoline hydrocarbons by a diverse group of microorganisms is an important removal process in surface waters, soil, and groundwater. Bioconcentration and sorption of gasoline hydrocarbons to soils and sediments may be important only for higher molecular weight hydrocarbons that are resistant to biodegradation. Exposure of the general population to gasoline occurs primarily through inhalation of very small quantities of the volatile fraction of the mixture during automobile refueling. Another important source of exposure is ingestion, dermal, and inhalation exposure for certain populations through the use of gasoline-contaminated surface water or groundwater in domestic potable water applications. -

Hydrocarbons Thermal Cracking Selectivity Depending on Their Structure and Cracking Parameters
Master in Chemical Engineering Hydrocarbons Thermal Cracking Selectivity Depending on Their Structure and Cracking Parameters Thesis of the Master’s Degree Development Project in Foreign Environment Cláudia Sofia Martins Angeira Erasmus coordinator: Eng. Miguel Madeira Examiner in FEUP: Eng. Fernando Martins Supervisor in ICT: Doc. Ing Petr Zámostný July 2008 Acknowledgements I would like to thank Doc. Ing. Petr Zámostný for the opportunity to hold a master's thesis in this project, the orientation, the support given during the laboratory work and suggestions for improvement through the work. i Hydrocarbons Thermal Cracking Selectivity Depending on Their Structure and Cracking Parameters Abstract This research deals with the study of hydrocarbon thermal cracking with the aim of producing ethylene, one of the most important raw materials in Chemical Industry. The main objective was the study of cracking reactions of hydrocarbons by means of measuring the selectivity of hydrocarbons primary cracking and evaluating the relationship between the structure and the behavior. This project constitutes one part of a bigger project involving the study of more than 30 hydrocarbons with broad structure variability. The work made in this particular project was focused on the study of the double bond position effect in linear unsaturated hydrocarbons. Laboratory experiments were carried out in the Laboratory of Gas and Pyrolysis Chromatography at the Department of Organic Technology, Institute of Chemical Technology, Prague, using for all experiments the same apparatus, Pyrolysis Gas Chromatograph, to increase the reliability and feasibility of results obtained. Linear octenes with different double bond position in hydrocarbon chain were used as model compounds. In order to achieve these goals, the primary cracking reactions were studied by the method of primary selectivities.
