PROCESS FLOW DIAGRAM OF CHILLING GAS
2005: Case Study: Membrane CO2 Removal from Natural Gas
CO2 concentration from 30% in the raw feed down to 3% in the sales gas. Figure 1. Grissik Gas Plant Process Overview The Grissik plant CO2 removal process utilizes both membrane separation and amine absorption technology, termed a membrane plus amine hybrid. A simplified process flow diagram is shown in Figure 2.

Jul 03, 2012This chapter covers different types of chemical process diagrams, how these diagrams represent different scales of process views, one consistent method for drawing process flow diagrams, the information to be included in a process flow diagram, and the purpose of operator training simulators and recent advances in 3-D representation of different chemical processes.
Natural Gas Liquids Fractionation Optimization - Emerson
Maximizing the recovery of natural gas liquids from natural gas improves margins for midstream oil & gas producers. In an earlier post, Optimizing the Process of Purifying Natural Gas Liquids we highlighted the role of advanced process controls and expertise in producing the right mix of hydrocarbons based on current market conditions.
Chilling Natural Gas To Control Hc Dew Point - Process
Apr 28, 2005Chilling Natural Gas To Control Hc Dew Point - posted in Process Heat Transfer: Relating to my post about the effect of the impurities of the natural gas...I have bad spec for sales gas (it has high HC dew point ranging from 150 to 85 deg F), this is because we have already signed the GSA and it has no dew point spec. Well now I want to build something to reduce the HCDP to 55 deg F. I've[PDF]
Natural Gas Liquefaction - NTNU
Gas liquefaction process - ideal Example: Natural gas at 60 bar, 10oC ambient temperature-270-230-190-150-110-70-30 10 50-6 -4 -2 0 Entropy, kJ/(kgK) Temperature, °C-273 W Q p=1.3 bar 20 bar • Heat is removed as the gas is 100 60 cooled at gliding temperature • Ambient temperature 10oC • Heat removed during liquefaction (Q), and ideal work (W), are shown
Turboexpander - Wikipedia
A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high- pressure gas is expanded to produce work that is often used to drive a compressor or generator. Because work is extracted from the expanding high-pressure gas,..
