INTRODUCTION

The Hetek Ethane Identifier, Model EI-5, is a portable, highly sensitive battery operated combustible gas analyzer designed specifically to detect the presence of Ethane in Natural Gas by elution (separation).

The Ethane Identifier is a supplementary instrument, used primarily when it is necessary to determine in the field, whether or not a particular combustible indication is the result of escaping utility natural gas or a conflict gas such as naturally occurring methane.

Occasionally, it becomes necessary for a gas utility to identify a combustible gas or vapor in the field, to determine whether it is the gas normally distributed by that utility, or perhaps a fermentation gas (marsh gas, landfill gas, soil gas) that is sometimes present in the ground or in sub-surface structures.

It has been found that a satisfactory “tracer” in natural gas distribution areas is Ethane. Ethane is usually present in significant concentrations in natural gas, but it is not present in the general run of conflict gases, such as fermentation gases, gasoline and solvents. In many areas, natural gas being distributed is de-ethanized to the level that the Ethane component is not detectable by old style hot-wire instruments. Ethane is being stripped out at the gas fields or scrubbing centres and diverted as a feedstock for the petrochemical industry. However, some residual Ethane still remains in natural gas and this Ethane is readily detectable by highly sensitive instruments such as the Hetek Ethane Identifier.

It must be understood that this instrument is not a quantitative instrument and does not replace a

Combustible Gas Indicator (C.G.I.). Users should continue to use a Heath Detecto Pak Infrared (DP-

IR) or Combustible Gas Indicator to locate and measure leaks.

Features:

• Detects the presence or absence of ethane in less than 2 minutes

• Graphical color display

• Building data logging

• Wrapping memory

• One second logging rate, 64000 reads

• Carrier gas not required/ Built in pump
