The Wobbe Index (WI) or Wobbe number is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas (LPG), and town gas and is frequently defined in the specifications of gas supply and transport utilities. 27 relations.

LPG is Liquefied Petroleum Gas, a mixture of propane and butane liquefied at 15 For LPG to have the same Wobbe index as CNG, it has to be mixed with air.

If VC is the higher heating value, or calorific value, and GS is the specific gravity, the Wobbe Index, IW, is defined as The Wobbe Index of LPG is 84. LPG is colourless, odourless, non-toxic, flammable, explosive and heavier than air. As it is approximately 1.91 times the weight of air, it tends to accumulate on the ground level. For safety reasons, LPG has a special odour added to help detect leaks. INTERCHANGEABILITY AND WOBBE INDEX USED AS QUALITY PARAMETER FOR LIQUEFIED NATURAL GAS Rafael Rosal 1 and Sabrina Di Scipio 2.

ประกาศกรมธุรกิจพลังงาน เรื่อง กำหนดลักษณะและคุณภาพของก๊าซธรรมชาติสำหรับยานยนต์ พ.ศ. ๒๕๕๒ Der Wobbeindex, auch Wobbewert, Wobbekennzahl, Wobbezahl (nach dem Gasingenieur und Erfinder Goffredo Wobbe, der ihn 1926 entwickelte), dient zur Charakterisierung der Qualität von Brenngasen (z. B. Erdgas, Stadtgas). 2012-01-10 · The wobbe index is an attempt to measure the gas stream to assure that is will burn properly without having to adjust the burner air/fuel adjustment.

Wobbe index has become necessary to provide early warning of changes in the composition. Whilst gas chromatographs provide very accurate measurements of all fuel gas components and physical properties (CV Bias Error +/- 0.1 MJ/m3), the response time is typically more than 90 s for a C6+, N 2 and CO 2 analysis.

Men jag har ingen OBD-läsare, och kanske This European Standard does not cover LPG containers for liquefied The Wobbe index is said to be gross or net according to whether the calorific value used Detta under förutsättning att Wobbe index * hos bränslet inte varierade. dvs där man i ett fall använder motorgas (LPG) tillsammans med bensin och i ett annat TS EN 13760 LPG-fyllningssystem för lätta och tunga fordon - Munstycken ISO 15971 Naturgas - Mätning av egenskaper - Termiskt värde och Wobbe-index.

Wobbe index: | The |Wobbe Index| (WI) or |Wobbe number||[1]| is an indicator of the interchangeabil World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled.

LPG is colourless, odourless, non-toxic, flammable, explosive and heavier than air. As it is approximately 1.91 times the weight of air, it tends to accumulate on the ground level. Wobbe Index From the measurement of CH 4 and C2+, the upper and lower heating value is calculated according to ISO EN6976-2005. An additional CO 2 measurement allows the determination of mean molar mass and specific density of the sample probe. Wobbe index is calculated from heating value and specific density, according ISO EN 6976-2005.

to ISO 6976 (Calculation of calorific values, density, relative density and Wobbe index from composition), the heating value of a natural gas could be calculated

By using air to reduce the LPG energy content, simulated natural gas and natural gas both have the same Wobbe Index. The LHV Wobbe Index Calorimetric Systems are specific integrated analysis systems aimed to assess, in real time, the following parameter(s) relevant to a gaseous stream: Wobbe Index; LHV Low Heating Value; Gas Density; Minimum Air Requirement CARI; Why those parameters? They are the simplest way. To understand the Energy Content of gas for Trading Automatic Wobbe Index Control for Peak Shaving Plants Wobbe Index of LPG/Air Mix SG SNG = 1.28 to 1.32 √1.28 = 1.1313 √1.32 = 1.1489 CV SNG = 1292 BTU/cuft @ 1.28 to 1476 BTU/cuft @ 1.32 Wobbe SNG = 1142 @ 1.28 to 1284 @ 1.32 Welcome To Oil, LPG, LNG and Chemicals cargo software By GSS Ops Team.

Wobbe Index for LPG. The Wobbe Index is used to compare the energy output of fuel gases in heating applications. It is often used as an indicator of the interchangeability of fuel gases, including LPG and natural gas. Wobbe Index is measured in megajoules per cubic metre of gas – MJ/m3.
