Paper Industries

In the paper industry, gas plays a vital role in helping manufacturers to maximize process efficiency, enhance quality and reduce environmental impact.
 

Tissue Soft and hard wood pulps or shredded paper which is up for recycling is mixed with water in the pulper. After the pulp is refined and made free of impurities, it is passed onto a felt and formed into a sheet. Due to capillary forces it sticks to the felt and gets transported to the first part of the drying where water is pressed out. It is then pulp transferred into Yankee cylinder whose interior is heated via gas. Next step is the creping section where the tissue is scraped from the Yankee cylinder and jumbo reels are produced. These are then cut and packed into napkins, toilet paper, household paper etc.
 

Paper When the wood logs arrive, they are fed into a rotating drum which removes the bark. The logs are then chipped. The largest source of wood chips for paper making is recycled off- cuts from industrial saw mills. The chips are then made to undergo a process called chemical pulping. This process breaks   down a chemical called lignin and the end result is pulp. This pulp is pumped into a large paper making machine. The pulp is squirted through a horizontal wire mesh to remove excess water. Here the fibers begin to spread out and take the form of a thin sheet which is rolled on jumbo reels. The sheets are then dried at above 100o C, over a series of gas fired cast iron cylinders. The final step involves cutting the sheets into various sizes, packing them and sending them out for sale.
