Process for energy-saving and safe transfer of gases

The invention relates to a process for the safe and energy-saving transfer of gases under high pressure, which is used in industry and at filling stations. The aim is to increase the efficiency of the transfer process and reduce energy consumption.

Background and state of the art

The previous transfer of gases under high pressure has several disadvantages:

 • Uneven pressure equalization: When connecting a filled pressure vessel to an empty container, the gas flows 

                  only until pressure equalization. A complete transfer is not possible without the use of high-pressure pumps.

 • Energy-intensive processes: High-pressure pumps cause high energy expenditure due to compression and heating of the 

                  Gases. Energy consumption is particularly significant for large quantities of gas, such as shipping or refuelling.

 • Incomplete emptying: Without pumps, tankers can only be emptied about halfway. This also applies to the 

                  Filling of tankers at refineries.

 • Compression and heating: Heating as compression increases allows less gas to pass in the 

                  storage container, as the gas volume is temperature-dependent.

In practice, step-by-step processes are used in which the gas is transferred in several stages as the pressure drops. However, these methods are inefficient and costly.

The invention aims to overcome the mentioned disadvantages. It offers a process that:

                  1. Works in an energy-saving manner,

                  2. Safe to handle high pressures,

                  3. Enables complete emptying and filling of containers,

                  4. Increases the efficiency of the transfer process.

Technical solution:

The innovation is based on an improved process that minimizes energy consumption while increasing safety. The technical details of the procedure include:

 • Optimized pressure equalization: Special mechanisms ensure uniform pressure equalization between the containers 

      without the need for high-pressure pumps, which means that more gas is stored in the receiving vessel   

      can.

• Efficient emptying and filling: tankers can be emptied or filled almost completely, regardless of the 

                 whether high-pressure pumps are used.

The presented solution offers several advantages:

                  1. Energy savings: The reduced use of high-pressure pumps significantly reduces energy consumption.

                  2. Cost-effectiveness: Less energy consumption leads to lower operating costs.

                  3. Higher capacity: By reducing the gas temperature during transfer, more gas can be stored in the 

                      storage container.

                  4. Flexibility: The process is suitable for both stationary tanks and mobile applications such as tank trucks 

                                  suitable.

                  5. Safety: Handling high pressures is made safer through optimized processes.

The process is suitable for various applications:

                  • Industrial plants: Efficient transfer of large quantities of gas in production processes.

                  • Refueling stations: Safe refueling of vehicles with compressed gases (e.g. CNG).

                  • Transportation: Complete emptying and filling of tankers during shipping or at refineries.

This invention represents a significant advance in the field of gas transfer by combining both environmental and economic benefits. It offers an innovative solution to existing challenges in industry and transportation.
