Liquefied Petroleum Gas primarily originates from refinery gas and associated gas from oil fields.

From refinery gas obtained

Refinery gas is a byproduct of the oil refining and processing process, with its quantity depending on the production methods and processing depth of the refinery, generally around 4%-10% of the original weight. Currently, the recovery of liquefied petroleum gas from the catalytic cracking gas at refineries is a major source for domestic LPG supply.

2. Extracted from associated gas from oil fields

Associated gas from oil fields is a byproduct gas generated during the oil extraction process. It is itself a combustible gas existing in the geological structure of the oil reservoir, containing 10%-40% of propane, butane, pentane, and higher carbon alkanes. During oil extraction, both oil and associated gas are emitted simultaneously. They are separated using gas-oil separation units installed above the oil well. The associated gas contains approximately 5% of propane and butane components, which can be extracted using absorption methods, resulting in high-purity liquefied petroleum gas with very low sulfur content. The liquefied petroleum gas supplied by countries such as Europe, the United States, and Japan is mostly of this type.

III. Derived from Natural Gas

Pure natural gas extracted from underground is divided into dry gas and wet gas. The methane content in wet gas is below 90%, with the content of ethane, propane, butane, and other alkanes above 10%. After the gas is compressed and fractionated, it is absorbed by diesel spray, then condensed into a liquid state at a pressure of 1.6 MPa in a fractionation tower, forming liquefied petroleum gas.

Safety Procedures for Tank Emptying

1. Prior to production or maintenance processes, first check the pressure, liquid level, and temperature of the filling and emptying tanks, and record them as accurate. Only then is it permitted to fill or empty the tank.

2. Determine the liquid output volume of the discharge tank and the incoming liquid volume of the receiving tank, and calculate whether the receiving tank's capacity meets the process and safety requirements, then confirm the tank transfer process.

3. The procedure is: open the liquid phase valves for in and out of the tank - adjust the vapor phase valves - start the circulating compressor.

4. When decanting, be mindful to monitor the storage tank's pressure and level changes, and continuously verify calculations. Do not exceed the highest permissible liquid level for incoming liquid tanks.

5. After decanting is complete, shut off the compressor, close the liquid phase valve, and then readjust the compressor valve.

6. Carefully fill out the operation records.
