Liquefied Petroleum Gas primarily originates from refinery gas and associated gas from oil fields.
One, obtained from the natural gas in oil refineries
Refinery gas is a byproduct of the oil refining and processing, with its quantity depending on the production method and processing depth of the refinery, generally accounting for about 4%-10% of the original weight. Currently, the recovery of liquefied petroleum gas from the catalytic cracking gas of refineries is the main source of domestic LPG.
Section II: Extracted from Associated Gas from Oil Fields
Associated gas from oil fields is a byproduct gas produced during the oil extraction process. It is itself a combustible gas that exists within the geological structures 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 wells. The associated gas contains approximately 5% of propane and butane components, which can be extracted using absorption methods to yield high-purity liquefied petroleum gas with very low * content. The liquefied petroleum gas supplied by countries in Europe, the United States, Japan, and other regions often falls into this category.
Section 3: Derived from Natural Gas
Pure natural gas extracted from underground is divided into dry gas and wet gas. Wet gas contains less than 90% methane, with more than 10% of ethane, propane, butane, and other alkanes. After the gas is compressed and fractionated, it is absorbed using 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 Decanting Operations
1. First, check the pressure, level, and temperature of the incoming and outgoing tanks based on production or maintenance requirements. After confirming they are correct, record the information and then proceed with tank transfer.
2. Determine the liquid output from the discharge tank and the incoming liquid volume to the receiving tank, and calculate whether the receiving tank's capacity meets the process and safety requirements; 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 valve—start the circulating compressor.
4. During decanting, pay attention to checking the storage tank's pressure and liquid level changes, and always reverify the calculations. The incoming liquid tank must not exceed the highest permitted liquid level.
5. After emptying the drum, shut off the compressor, close the liquid phase valve, and re-adjust the compressor valve.
6. Carefully fill out the operation records.

Heze Boiler Factory Co., Ltd. is a producer of liquefied gas tanks in China.5--200Overall annealing furnace for cubic liquefied gas tanks, steel column sandblasting and rust removal, advanced manufacturing management, procurement of high-quality raw materials, and the welding techniques of skilled welders forge a liquefied gas tank production base.
LPG storage tanks are pressure vessels designed for storing liquefied petroleum gas. They are special equipment that can only be produced by enterprises approved by the National Quality Supervision and Inspection总局. To produce these tanks, a Class 3 pressure vessel design and manufacturing qualification from the state is required. Shandong Heze Boiler Factory Co., Ltd. is a state-approved enterprise for the design and manufacturing of Class 1, 2, and 3 pressure vessels and can produce pressure vessels such as LPG storage tanks below 200 cubic meters. It is one of the few nationwide that can produce such equipment.200Cubic Enterprise.
Liquefied Petroleum Gas (LPG) storage tanks are selected according to national standards.Q345RSteel plates, typically sourced from Jinan Iron and Steel Plant or Anyang Iron and Steel Plant, both of which are major state-owned steel enterprises in China, ensuring quality in the steel plate material. Our technical team will re-inspect the steel plates to confirm their qualification after purchase. Qualified steel plates undergo a series of processes including rolling, splicing, welding, flaw detection, annealing, hydraulic and pneumatic testing, sandblasting for rust removal, and painting, all using state-of-the-art production techniques to guarantee the quality of the storage tanks. Liquefied gas storage tanks are primarily used in liquefied gas stations. The production process of these tanks involves multiple steps, with key ones including: selecting raw materials from reputable large-scale steel manufacturers; our company uses materials from the state-owned steel enterprises in Jinan and Anyang. Next, the tanks must undergo full annealing after welding, which is to eliminate stress in the steel plates, making the tank a single unit and preventing weld cracks. Additionally, we employ shot blasting to remove rust, using steel grit of one to two millimeters to sandblast the tank's surface. This method effectively removes rust and the paint can last longer.***Our company has chosen products from large paint manufacturers, applying two coats of anti-rust primer followed by two coats of topcoat. Four layers of paint ensure the storage tank will not peel off for five to ten years, and with good maintenance, it can last up to twenty years without the need for repainting.
