Acetylene for Chemical Synthesis
Acetylene is a versatile tool in today’s speciality and fine chemical industry for its very special and controllable reactivity in a great variety of synthetic applications
The synthetic potential of acetylene paves the way to various applications in the chemical industry, e. g. for production of perfume components, vitamins, polymer additives, solvents and surface active compounds.
Hydrogen is widely used in the production of bulk chemicals, intermediates and speciality chemicals
Mixtures of hydrogen (H2) and carbon monoxide (CO), known as syngas, are fed to processes for large scale production of methanol and various so-called oxo products like higher alcohols and aldehydes.
Among other applications is e. g. the elimination of oxygen from boiler feed water.
Main processes for hydrogen production:
- Steam reforming of methane or other hydrocarbons
- Gasification of organic feedstock to syngas (H2/CO)
- Recovery from gaseous waste streams
- Electrolysis of NaCl.
Hydrogenation of Oil & Fat
Prolonging the shelf life and increasing the stability of edible oils
Hydrogenation using oils and fats from oils can become rancid when exposed to oxygen. The challenge lies in stabilising these oils to increase their shelf life.
One way of achieving this is through hydrogenation. This involves chemically converting fatty acids to reduce the number of double bonds. In practical terms, hydrogenated oil is far more shelf-stable and will not go rancid as quickly as untreated oil. It also has a higher melting point, making it ideal for frying and pastry-making.
VOC Abatement & Solvent Recovery
Preventing the release of volatile organic compounds and increasing the recovery of solvents
The fine & specialty chemical sector and the pharmaceutical industry use solvents to manufacture products and to distribute/store final or intermediate products. This can pose a challenge for manufacturers, who must ensure that volatile organic compounds (VOCs) are not unwittingly released into the atmosphere.
As VOCs represent a serious health and environmental hazard, their release is strictly regulated by law. Manufacturers must also control evaporation losses, as their products can otherwise literally vanish into thin air.
We offer a wide range of complete cryogenic solutions to minimise the release of VOCs into the atmosphere and to recapture lost substances.
Stirring Mixing and storing liquids using nitrogen
Stirring Nitrogen gas provides a flexible tool for mixing and storing liquids. It offers considerable advantages over conventional stirring methods.
No mechanical devices are needed, so there is no reaction with the liquid and no subsequent cleaning is necessary.
The method is readily controllable and offers the added advantage that it introduces no new oxygen into the system while at the same time reducing the oxygen content.
White Liquor Oxidation
Increasing capacity without large investment
Oxygen may be used alone or as a complement to air when oxidising white liquor. In several mills, oxygen supplied by our systems is used for white liquor oxidation. The oxygen is used as a complement to air. By adding oxygen to existing white liquor oxidation equipment, increased capacity can be achieved without any larger investments.
Benefits with adding oxygen to existing air oxidation equipment include:
- Increased production of oxidised white liquor
- Use of existing equipment
- Low investment cost
- Simple installation.
