China Factory Direct Sale Gas Refrigerant R290 Replacement R-22 High Purity

QUICK DETAILS

PRODUCT BRIEF INTRODUCTION

High purity gas refrigerant R290 Description

1. R290 is used as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners.

2. R290 is used as a replacement for the for the more environmentally harmful R22 and retrofit kits are availableto convert units that were originally R22 equipped.

3. Other uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals.

Description:

Propane is called R290,a three-carbon alkane with the molecular formula C3H8,
normally a gas, but compressible to a transportable liquid.
Propane is produced as a by-product of two other processes, natural gas
processing and petroleum refining. The processing of natural gas involves removal of butane, propane, and large amounts of ethane from the raw gas, in order to prevent condensation of these volatiles in natural gas pipelines. Additionally, oil refineries produce some propane as a by-product of cracking petroleum into gasoline or
heating oil. The supply of propane cannot easily be adjusted to meet increased demand, because of the by-product nature of propane production.

Application:
Propane is a popular choice for barbecues and portable stoves because the low boiling point of ?42 °C (?44 °F) makes it vaporize as soon as it is released from its
pressurized container. Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices. Propane powers some locomotives, buses, forklifts, taxis and ice resurfacing machines and is used for heat and cooking in recreational vehicles and campers. Since it can be transported easily, it is a popular fuel for home heat and backup electrical generation in sparsely populated areas that do not have natural gas pipelines.
