Natural gas analyzer, gas calorific value, nitrogen blending analysis equipment

Natural gas analyzer, gas calorific value, nitrogen blending analysis equipmentProduct Introduction:

Our company has recently developed a portable gas chromatograph with the characteristics and advantages of light weight, easy portability, and small size. It can achieve full analysis of hydrocarbon components such as oxygen, nitrogen, methane, ethane, carbon dioxide, propane, isobutane, n-butane, n-pentane, isopentane, and C6+in various gases with a single injection. An instrument that uses calorific value software to automatically calculate the content of detected gas components, high calorific value, low calorific value, density, relative density, white number, combustion potential, and generate reports.

Development background:

With the rapid development of China's gas industry, under the guidance of the West East Gas Pipeline national policy, our company actively develops supporting equipment for gas field applications. We have successively developed gas detection instruments for the mixing of dimethyl ether, methanol, formaldehyde, nitrogen, carbon dioxide and other gases in liquefied gas. According to the 13th Five Year Plan and the comprehensive implementation of the coal to gas policy, our company has also developed a gas calorific value analyzer, which can achieve full analysis of various hydrocarbon components such as oxygen, nitrogen, methane, ethane, carbon dioxide, propane, isobutane, n-butane, n-pentane, isopentane and C6+in a single injection. An instrument that uses calorific value software to automatically calculate the content of detected gas components, high calorific value, low calorific value, density, relative density, white number, combustion potential, and generate reports.

Application areas of natural gas blending and calorific value analysis:

There are many industries including LNG CNG refueling stations, oilfield gas, coalbed methane, mine gas, shale gas, gas pipeline transportation companies, gas transportation companies, gas reserve stations, coal to gas conversion enterprises, LNG point supply, gas appliance production enterprises, petroleum refining, coking plants, smelters, and gas supply stations.
