IChEC9 Part 5: Separation Processes 9th Iranian Chemical Engineering Congress (IChEC9) Iran University of Science and Technology (IUST) 23-25 Nov 2004 1718 Dehydration by absorption In this case natural gas is dried by counter current scrubbing with a solvent that has a strong

Comparison of natural gas dehydration methods [1 2] General overview of applicability of each dehydration method is shown in figure below General selection chart of natural gas dehydration method [1 with modification] Bonus: Conversion Table of Natural Gas Water Content When I read several literatures related to natural gas dehydration the

Abstract—Natural gas from reservoirs usually contains water vapor the presence of this vapor causes flow assurance issues hence the need to dehydrate the gas and optimize the process Optimization of natural gas dehydration using Tri-ethylene glycol was carried out using Aspen HYSYS process software and regression analysis

Natural gas as most of us know it is very different from that lying underground Raw natural gas must undergo a number of processes before entering downstream equipment to remove various impurities including water vapour which increases the corrosiveness of natural gas

Honeywell UOP Introduces New Connected Plant Service

Honeywell UOP's ARMGuard system uses existing instrumentation to help customers optimize their adsorption cycles reduce energy consumption operate under variable feed conditions and reduce costs due to unscheduled shutdowns Natural gas at the wellhead naturally contains water and water vapor that if left in the natural gas stream will freeze as the gas is being cooled into a liquid

Natural gas dehydration Introduction Natural gas dehydration is the process of water removal associated with natural gases 2 Source of Water Content in Gas • Water vapor in gas streams depend upon certain condition prevailing in the reservoir – Temperature – Pressure – Amount of free water produced with gas • Water content in gas is sometime due to the aqueous solution used in

Globaltechexport dehydration systems remove entrained water to avoid liquid drop out and bring gas stream to Customer required specification We have experience with dehydration systems including ethylene glycol and tri-ethylene glycol dehydration as well as physical adsorption via molecular sieve dehydration

Gas dehydration is the process of removing water vapor from a gas stream to lower the temperature at which water will condense from the stream this temperature is called the "dew point" of the gas Molecular sieves are considered as one of the most important materials that are used as desiccant materials in industrial natural gas dehydration

Abstract—Natural gas from reservoirs usually contains water vapor the presence of this vapor causes flow assurance issues hence the need to dehydrate the gas and optimize the process Optimization of natural gas dehydration using Tri-ethylene glycol was carried out using Aspen HYSYS process software and regression analysis

Silica Gel Adsorption for combined Water Hydrocarbon Dew Point Control: Silica gel is porous solid in form of beads able to adsorb both water heavy hydrocarbons (C6+) from natural gas It is suitable for treating high pressure natural gas streams allowing the control of both water and hydrocarbon dew points in a single process unit and with minimum pressure drops

dehydration of natural gas [1]: • Dehydration by absorption • Dehydration by adsorption (solid desiccant) • Dehydration by gas permeation • Dehydration by gas refrigeration Among these methods dehydration by absorption has more popularity in industrial units

Absorption and adsorption are two natural occurring processes that are similar but are not the same Here is a basic breakdown of how they are different: absorption occurs when one material's physical state is absorbed into another material's physical state while adsorption occurs when one material physically sticks to another material without changing it's physical state

Simulation of Natural Gas Dehydration Process

Dehydration of natural gas is needed to remove the water that is associated with natural gases in vapor form [1] The demanding of the natural gas in recent decades have been raised dramatically Nowadays the natural gas poses a huge rule in the world economy and development However natural gas exists in deep underground

Petroleum Extension-The University of Texas at Austin Dehydration of natural gas through absorption and adsorption 5 In this chapter: • • Dehydration Hydrate formation control through dew-point depression • Liquid-desiccant dehydrator systems and how they operate • Plant operation problems with the use of liquid-desiccant dehydra tors of Natural • Solid-desiccant dehydrator systems

Dehydration of Natural Gas This chapter covers the three common methods for dehydrating natural gas: absorption by a glycol (typically triethylene glycol) refrigeration and adsorption by molecular sieves The processes are described in some detail Simple methods are presented for designing them

Adsorption (or solid bed) dehydration is the process where a solid desiccant is used for the removal of water vapor from a gas stream The solid desiccants commonly used for gas dehydration are those that can be regenerated and consequently used over several adsorption-desorption cycles

Abstract Natural gas is an important source of primary energy that under normal production conditions is saturated with water vapor Water vapor in a natural gas stream can result in line plugging due to hydrate formation reduction of line capacity due to collection of free water in the line and increased risk of damage to the pipeline due to the corrosive effects of water

Natural Gas Dehydration 5 temperatures and the absorbed water is boiled out from TEG during regeneration in a reboiler at high temperatures Some physical properties of pure TEG are given in the following text Viscosity data vs temperature is shown in Table 1 and is shown in a graph in Figure 1 [6]

Natural gas must be purified before it can be transported The preparation process also includes a drying step to remove water Microporous adsorbents such as zeolites are used for this purpose but they often need to be heated to temperatures up to 250C to remove the water so that they can be reused Cadiau et al describe a fluorinated metal-organic framework containing nickel metal

Absorption and adsorption are two natural occurring processes that are similar but are not the same Here is a basic breakdown of how they are different: absorption occurs when one material's physical state is absorbed into another material's physical state while adsorption occurs when one material physically sticks to another material without changing it's physical state
