Sulphite process paper
The sulphite process is an industrial process to produce wood pulp suitable for wood low in resin and silicic acid.The advantages of this process are above all the very efficient delignification, the good bleachability, the high reactivity during further processing and low investment costs. In the sulphite process, the wood fibres are digested in an acidic or neutral medium. In the process, the lignin is subjected to sulphonation and is thereby converted into a water-soluble salt which can be removed from the cellulose. The by-product lignosulphonates are either commercially recovered or incinerated (recovery). In case of recovery the black liquor separated from the fibres during pulp washing is evaporated and burned in the recovery boiler using oxygen. The very light pulps produced in this way are today used almost exclusively for the production of chemical cellulose or paper. To produce one tonne of pulp you need about five cubic metres of wood and 90 kilograms of sulphur.
Ready made meals
Ready-made meals make cooking easier as the consumer is freed of any preparation, except for the heating of the food. The varied range of ready-made meals also reflects the complexity of the manufacturing process. Gases from Messer are used in many of the individual process steps. These include the mixing, cooling, freezing and packaging of the products.
Spices and herbs process chart
Herbs and spices have become an integral part of our food. During their processing they are often ground, cooled or frozen and packaged. Gases from Messer play a role in many of these applications.
Meat processing process chart
Meat production consists of a number of individual processes: from animal breeding to slaughtering, and via various steps, to the packaging and sale of the product. Gases are used in many of these stages with Messer supplying the necessary know-how, equipment and of course, gas.
