Pulp and Paper Industries

Erivac provides equipment for Pulp and Paper Industries

As for many other Industries also the traditional Pulp and Paper Industry is looking for improvements and how to make better use of potentially valuable side products such as: – BioFuels from Tall Oil; – Methanol production; – Lignin separation from black liquor; – Turpentine; – Sulphuric Acid from off-gas; – BioGas and BioPellets; – New BioChemicals; etc. Many Pulp mills, using the Kraft (sulfate) process, are also self-sufficient in energy, export electricity to the grid and provide district heating to nearby cities. Modern Pulp Mills also have the potential for a Negative Carbon Foot Print with the use of Carbon Capture and Storage or Utilization. New concepts are created and these new mills are often called BioPruduct Mills.

Pulp and Paper Industries

Steel Industries has many process steps, each with its individual necessity of units operations: – Vapour Recompression often by Thermocompressors; – Vacuum is necessary for Black Liquor Evaporation; – Several processes produce off-gas with contaminants that need Gas Cleaning; – Heat Transfer (heating, cooling, heat interchange) for dirty fouling media, in many cases also carrying fibers; – Large amounts of cooling water is used that requite adequate filtration and sometimes elimination of mussels and mussel larvae. 

Ejectors and Vacuum Systems

 – Vacuum Ejectors. Steam Jet Heaters and ThermoCompressors

 – Steam Jet Vacuum Systems and Liquid Ring Vacuum Pumps  for black liquor evaporation

 – Jet- and Venturi Scrubbers for gas cleaning

 – Steam Jet Chillers for chlorine dioxide cooling water

 – Eductors for Tank Mixing and Jet Aeration for Waste Water Treatment

Heat Exchangers 

 – Spiral Heat Exchangers for liquid/liquid applications with dirty fouling media, in many cases also carrying fibers, as economizers, heaters / coolers, or in two phase applications as condensing or evaporation operations, steam heaters, reboilers, etc.

 – Welded Plate Heat Exchangers. These are for applications as above but for less dirty or semi-fouling media.

 – Gasketed Plate Heat Exchangers


 – Automatic Filters for protection of heat exchangers and spray nozzles for reduced maintenance necessity and increased plant availability, filtration of raw water and cooling water circuits. If Sea or Brackish Water is used, acting as effective mussels and mussel larvae stop.
