Expert ASME pressure vessel manufacturers with a deep understanding of material science, stress analysis, thermal considerations, and industry standards are essential to create reliable and efficient pressure vessels. As technology and industrial demands continue to evolve, the importance of expertise in pressure vessel design remains indisputable in ensuring the safety and success of various industrial processes.

Pressure Vessels That Demand Quality Engineering

The safety, durability and reliability of pressure vessels are critical and therefore require quality engineering. Companies that require pressure vessels demand the very best quality. So controlled production and rigorous testing are required.

Ensuring they’re built to ASME standards and using top-tier manufacturers for high pressure gas compressors, supercritical CO2 extraction equipment and custom reactor vessels.

What are pressure vessels?

Pressure vessels are closed containers. Housing liquids and gasses at a pressure that’s different to ambient pressure, they are often created using a range of materials.

They’re often used in a variety of industries where gas recovery systems and pressurized liquid storage are indicated. Whether that’s oil and gas, chemical or food processing industries. Types of pressure vessels that are typically created include heat exchangers, flash drums and reactors.

In order for pressure vessels to be appropriate for use, every manufacturing aspect needs to meet several standards and regulations. The ASME Boiler and Pressure Vessel Code is the one that is universally known by manufacturers of these containers.

How they’re made and their usage

Many of the pressure vessels are made of steel. Other materials include aluminum, stainless steel, and titanium, all of which are known for their durability. To manufacture such products, the steel is manufactured to the right thickness and cut to the shape required.

From a lab-scale high-pressure reactor that allows for reactions to pressure while resisting corrosive acids to a closed-loop CO2 extractor to extract cannabinoids. Both are examples of pressure vessels.

Types of pressure vessels and their material selection

There are a number of pressure vessel types that vary depending on their intended usage. A few examples include:

  • Storage vessels – Temporarily hold liquids, gases and vapors.
  • Heat exchangers – Help to transfer heat between two or more fluids.
  • Boilers – Utilizing fuel, nuclear or electrical power as heat.
  • Process vessels – Broader use for mixing and agitation, distillation, and mass separation to name but a few. 
  • Distillation columns – Separates a mixture of liquids based on their volatilities.
  • Industrial mixers – Powered with motor-powered blades to emulsify a single mixture or multiple mixtures.
  • Jacketed reactors – Maintain the temperature during a chemical reaction.

How their materials are selected

Part of manufacturing quality pressure vessels comes with knowing what materials are best for each task. Meeting the strength requirements and corrosion resistance are some of the physical attributes that can determine what materials are used. Other factors may be the return on investment and the availability of the materials in question.

The importance of quality and expert engineering

Using hydrogen compressor manufacturers that are skilled in the creation of pressure vessels and maintain ASME certifications is critical. A high quality pressure vessel requires strenuous testing at extreme conditions before being placed into service. The accidental release or leakage of contents of an untested unit can be a threat to the environment and the individuals working in close proximity of that vessel.

The Colors of Hydrogen Recovery

Being the most abundant substance in the entire universe, it comes as no surprise why hydrogen vital to so many different applications. But for hydrogen atoms to be usable, they need to be split first from other atoms (they’re often attached to another atom, like oxygen and carbon dioxide).

With the help of hydrogen compressor systems, hydrogen atoms can be extracted, compressed, and stored for future use. Today, compressed hydrogen is being utilized to provide cleaner energy, produce fertilizers, and process food to name just a few of those applications.

Hydrogen, in itself, is an invisible, colorless gas. But in the energy industry, there are color codes used to identify how that hydrogen was sourced and produced. Here are the different colors of hydrogen recovery.

Brown/black hydrogen. Long before any manufacturer of electrochemical hydrogen compressors existed, people generated hydrogen by transforming coal into gas. This old method is the most environmentally damaging — which is why the colors brown and black hydrogen is used to describe hydrogen recovery from fossil fuels. Brown hydrogen refers to hydrogen produced using lignite coal; black for bituminous coal.

Blue hydrogen. To have cleaner hydrogen, people began recovering hydrogen from natural gas by mixing natural gas with hot steam and a catalyst. The result is hydrogen and carbon dioxide splitting. The hydrogen is then stored and the CO2 is also captured to minimize the effects on our environmental. The CO2 is repurposed in other applications.

Gray hydrogen. Similar to blue hydrogen, gray hydrogen is generated through natural gas reforming. The only difference is that the CO2 byproduct isn’t captured after the process.

Green hydrogen. Considered the ideal color of hydrogen, the green hydrogen is produced through electrolysis. This process, often used with a hydrogen compressor systems only has hydrogen and oxygen as its by-product. By not using (and producing) polluting chemicals and utilizing renewable energy sources to perform the electrolysis, green is the cleanest color of hydrogen. Its why key players involved in green hydrogen recovery are aiming to increase their output. By 2030, it’s estimated that green hydrogen generation will increase 22 times than today’s output.

Turquoise hydrogen. Though its still relatively new, turquoise hydrogen is already attracting attention and is hugely considered to be a better commercial option in the near future. Turquoise hydrogen is produced through methane pyrolysis. It’s a fundamentally new process, technologically advanced, requiring relatively smaller amounts of energy to split hydrogen atoms from solid carbon. Similar to blue hydrogen, its cleanliness depends on how the solid carbon can be captured so that there will be little to no greenhouse gas emissions.

Pink hydrogen. Today, many hydrogen compressor manufacturers are focused on producing cleaner energy — more green hydrogen, to be more exact. But there are other cleaner colors of energy as well. Pink hydrogen, for instance, is much like its green counterpart, only that it uses nuclear energy to fuel that electrolysis process.

Yellow hydrogen. If pink hydrogen’s electrolysis process uses nuclear energy, yellow hydrogen uses solar power. In generating green hydrogen, a manufacturer may use a combination of various renewable energies, such as solar and wind.

Hydrogen can be the fuel of the future that will help shape economies and how people live. With advancements in technologies that can help scale clean hydrogen, it can be used in vital sectors such as power generation and transport.
