Calibration of online natural gas analyzer

GC-7850 Fully Automatic Gas Calorific Value Analyzer

Preface

With the comprehensive implementation of the coal to gas policy, it is being carried out nationwideThe 'coal ban'. Coal fired boilers are gradually being phased out, while the number of gas-fired boilers is increasing. Gas prices are constantly rising with market demand. Driven by profit, some gas merchants, in order to obtain considerable economic profits,InMixing liquid nitrogen into LNGAccording to industry insiders, liquid nitrogen was originally only used for adjustingThe fixed calorific value of LNG has gradually become a profit-making method for some unscrupulous merchants due to profit driven factors. Shanghai Xuansheng Company has developed a portable fully automatic gas calorific value analyzer to recover losses for LNG users in response to this phenomenon,Can be implemented forLNG/CNGMedium nitrogen, carbon dioxide, methane, ethane, propaneButane, pentaneC6A specialized instrument for comprehensive analysis of component content, high calorific value, low calorific value, density, relative density, Huabai number, combustion potential, etc.

Product Description: How to Translate

GC-7850 fully automatic gas calorific value analyzer, is the most advanced instrument of Shanghai Xuansheng Scientific Instrument Co., LtdA newly produced high-performance instrument, mainly used forLNG blending solutionNitrogen, carbon dioxide, methane, ethane, propane in LNGButane, pentaneC6And the gasification rate can be calculated based on density.

The instrument has a stylish appearance and beautiful design;12 inch display screenDisplay rich and intuitive content; Small size, light weight, easy to carry, suitable forLNG user laboratory testing and analysis are also suitable for gas companies to carry instruments to multiple user points for testing.

The operation of this instrument is very simple, even personnel who have not been in contact with this instrument can learn it at once.Insert the sampling bag for gas into the instrument'Sample in' inlet, press' start 'button to automatically run the instrument（Automatic sampling, automatic analysis, and automatic signal acquisition without the need for manual intervention）.Automatically calculate the detection results within 10 minutes.

Product performance advantages：
