All customerprocesses that use gases - Strategic application technology
On the paper machine, paper is produced out of processed plant fibers (mechanical, chemical pulp, recycled fibers). At first fibers are distributed in water, pre-treated, mixed with other raw materials and - after further dilution and making the water/fiber mixture as uniform as possibly - introduced to the headbox. From there, this suspension is brought to the wire where sheet forming and the first step of dewatering takes place. Further dewatering steps are carried out in the press section and the drying section. In the water circuit of the paper machine the major amount of water used for paper making is recovered.
Soft drinks process charts
The production of soft drinks usually takes place following the same process: the drinking or spring water stored in inertised tanks is freed from unwanted constituents, in particular oxygen; it is then mixed with beverage concentrates and optionally carbonated. The finished soft drinks are finally filled into bottles or cans at filling stations and delivered to the market.
Sulphate process paper
The sulphate process (also known as "Kraft digestion" because of the strength of the paper made using it) is the most common process for making paper pulp from cellulose. Lignin contained in the plant material is separated by cooking in an alkaline medium containing sodium sulphate and sodium hydroxide ("white liquor"). The pulp is screened, washed and bleached. By clever combination of process steps, the chemicals used can be largely recovered, with gases increasingly being used here.
Sulphur chemistry process chart
The raw material for sulphuric acid production is elemental sulphur, which is produced during the processing of fossil raw materials. Sulphur recovery is becoming more and more important due to falling emission limits and is usually realised using the Claus process. 90 % of the sulphur thus obtained is converted to sulphuric acid, which is one of the most technically important and highly produced basic chemicals, and is used to a great extent in fertiliser production.
