Honeywell Elster® EnCal 3000

Honeywell Elster® EnCal 3000 is a gas chromatograph analyzer specially designed for natural gas energy measurements. This state-of-the-art analyzer uses chromatography components based on the latest Micro-Electro-Mechanical Systems (MEMS) and capillary column technique that provides accurate and highly consistent analysis results. The device features a compact, explosion-proof design and includes analytical hardware, stream selection and required electronics for standalone operation.

What Is It?

In natural gas energy measurement, calorific value is a key component that determines the energy content flowing through a pipeline, along with volume, pressure, and temperature measurements. EnCal 3000 helps gas transmission & distribution companies as well as end-users consuming large amounts of gas accurately measure of single gas components since wrong measurements can directly impact the bottom line.

EnCal 3000 versions:

  • C6/ C9 for heating value determination in natural gas

  • Biogas analyzer

  • e-Gas: Hydrogen + Natural gas

  • H2S analyzer: to measure hydrogen sulfide in natural gas

  • Odorization analyzer to measure THT and/or TBM in natural gas.

How Does It Work?

EnCal 3000 analyzer injects natural gas into a carrier gas stream that further proceeds to a column where natural gas is separated into its constituents. The separated constituents then pass a calibrated detector in peaks and the area of these peaks is dependent on the constituent’s concentrations. With collated data from the constituent’s concentrations, the heating value / Wobbe-index / density of the natural gas is calculated.

What Problems Does It Solve?

EnCal 3000 offers the following benefits:
  • Provides insight on the energy content of any type of gas for billing purposes

  • Provides insight on the energy content and other parameters of any type of gas for plant control purposes

  • Allows measurement of almost any gas mixture.
