AIR GAS

PROCESSES

Technical gases can be generated by various processes. Oxygen, nitrogen, argon and noble gases in air separation plants, hydrogen by electrolysis, helium from natural gas, among other things. HEROSE supplies high-quality cold-box valves and control valves for this purpose to control the operation of the plants and to regulate and thereby ensure that the air is broken down both in the desired amount and at the desired pressure.
In air separation, air is divided into its components. The different boiling temperatures of the gases form the basis for the gas separation. For large purchase quantities, customers use their own air separators instead of storage tanks.
HEROSE valves and fittings help ensure the safety and reliability of the systems.
Cryogenic areas of application include the food industry, welding and laser technology, medicine, shipbuilding, pharmacy and many more.

TRANSPORT

In order to get technical gases from the production site to the customer, they are transported either via pipelines or cryogenically liquefied by truck on public roads in special vacuum-insulated containers or tanks. In the vacuum space between the inner and outer tank, MLI insulation is preferably used here (multi layer isolation). The volume is the lowest here and at the same time there is a weight saving compared to e.g. Perlite.
Valves and fittings help to ensure safe and reliable operation of the transport containers. They are used to fill the respective customer tank with the required quantity of the gas to be transported, depending on the operating pressure. Valves, such as the HEROSE shut-off valves and actuated valves, help to ensure that transport is safe and reliable. Since these valves are used very frequently for filling and discharging, they are exposed to the toughest conditions.

STORAGE

In stationary containers, cryogenic liquefied industrial gases can be stored for further distribution without major evaporation. The cryogenic liquefied product is mainly stored in vacuum-insulated containers under customer-specific overpressure. In contrast to the transport containers, the vacuum space is usually filled with perlite. In the case of discontinuous acceptance by of the customers, overflow valves or pressure regulators are used to maintain the operating pressure before the main safety valves prevent impermissible pressure excesses.
Different container sizes (from 5,000 to 50,000 liters capacity) are used depending on the quantity and frequency of the customer's purchase.The wide range of products from HEROSE offers the right fittings for every tank. These are used as intended and meet the respective requirements of the area of application.

LIQUEFIED NATURAL GAS (LNG)

STORAGE

LNG is stored in different ways. In addition to terminals, the cryogenic liquefied natural gas can also be stored in caverns or tanks. The LNG is stored under atmospheric pressure in the storage tanks or LNG terminals until further transport or until regasification. Different sizes of containers are used, depending on the quantity and frequency of collection.

TRANSPORT

LNG is transported in two ways - in gaseous form via pipelines to urban centers, power plants or large customers. On the other hand, it is also transported in the cryogenic liquefied state by road, by ship (LNG Cargo) or rail.
While so-called tank wagons are mainly used for transport by rail, trailers are used in addition to containers for road transport. The transport takes place in the cryogenic liquefied. For this reason, the tank wagons, like the trailers, are equipped with special vacuum-insulated tanks for road transport.
