pressure vessel for gas storage

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Construction methods and materials may be chosen to suit the pressure application and will depend on the size of the vessel, the contents, working pressure, mass constraints, and the number of items required.
Inside the cylinder, the stored contents may be in a state of compressed gas, vapour over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.

Types of pressure vessel

Several pressure vessel types are used for gas storage, each designed to suit specific applications and requirements. The main types of pressure vessels for gas storage include:

  • Cylindrical Pressure Vessels: These vessels have a cylindrical shape and are commonly used for storing gases under high pressure. They are often made of steel or composite materials and can be either horizontal or vertical in orientation.
  • Spherical Pressure Vessels: Spherical vessels have a spherical shape, offering excellent strength and uniform pressure distribution. They are commonly used for storing gases at high pressures and are often found in industries such as oil and gas.
  • Tube Trailers: Tube trailers are long cylindrical pressure vessels that transport compressed gases. They typically consist of multiple interconnected cylinders or tubes mounted onto a trailer chassis. Tube trailers are commonly used to transport gases like hydrogen, compressed natural gas (CNG), and other industrial gases.
  • Cryogenic Storage Tanks: Cryogenic storage tanks are specialized pressure vessels that store liquefied gases at extremely low temperatures. They are heavily insulated and typically used for gases such as liquid nitrogen (LN2), liquid oxygen (LOX), and liquefied natural gas (LNG).
  • Underground Storage Vessels: These pressure vessels are designed to store gases underground for various purposes, such as storing compressed natural gas (CNG) for fueling stations or underground storage of liquefied petroleum gas (LPG).
  • Bullet Tanks: Bullet tanks are horizontal pressure vessels with rounded ends that store gases at moderate to high pressures. They are commonly used in the oil and gas industry to store propane and butane gases.
  • These are some of the common types of pressure vessels for gas storage. The selection of the appropriate type depends on factors such as the type of gas, required pressure, storage capacity, transportation needs, and specific industry requirements.

    Storage vessels/tanks are superficial vessels for storing liquids, solutions, pharmaceutical raw materials, and other chemicals.
    These general-purpose vessels are made of stainless steel, fibreglass, titanium, and galvanized steel.
    Several industries use them to store various substances and solutions.
    Storage vessels/tanks can either be horizontal or vertical in their orientation.
    Horizontal storage vessels are generally mounted on stands or saddles and have an access hatch on the bottom or top.
    Vertical storage pressure vessels are erected vertically and usually have access ports on the bottom.
    These specialized vessels can be placed above or below ground, depending on the construction of the storage facility.
    The wall thickness of the vessel determines the application and the use of the boat; while single-wall storage vessels can be used for general applications, double-wall containers are generally used for high-pressure considerations.
