ASTM D1142 Dew Point For Gaseous Fuels

KN-1142 Dew Point for Gaseous Fuels

Overview

KN-1142 Dew Point for Gaseous Fuels conforms to ASTM D1142 Standard Test Method for Water Vapor Content of Gaseous Fuels by Measurement of Dew-Point Temperature. Generally, contracts governing the pipeline transmission of natural gas contain specifications limiting the maximum concentration of water vapor allowed. Excess water vapor can cause corrosive conditions, degrading pipelines and equipment. It can also condense and freeze or form methane hydrates causing blockages. Water-vapor content also affects the heating value of natural gas, thus influencing the quality of the gas. 

Features

1. It is mainly used for the detection of hydrocarbon dew point and water dew point in natural gas.

2. This apparatus adopts the cold mirror detection principle, which has high detection accuracy and stability, and is suitable for commercial inspection and measurement or on-site inspection.

3. The cold mirror refrigeration adopts a CO₂ refrigerator with a cold energy recovery system.

4. The cooling efficiency of the refrigerator is compared with traditional The CO₂ cooler has increased by more than 50%, which improves work efficiency while reducing the loss of cooling media.

5. The apparatus is also suitable for a variety of refrigeration media including dry ice and liquid 

6. nitrogen, with a wide detection range and strong environmental adaptability.
