Pulp and paper production is a technological process focused on making of pulp, paper, cardboard and other finished or semifinished by-products.

For production wood and much water is required. That is why pulp and paper mills are usually located on the banks of big rivers where it is possible to float wood that is the basic material for production.

Standard technological process of pulp production consists of the following steps:

-         Production of chips from raw wood;

-         Pulp cooking in continuous boilers;

-         Pulp bleaching;

-         Pulp drying;

-         Regeneration of cooking chemicals.

Practically at all production stages gas-analysis equipment is used for technological purposes and for safety provisions.

The following standard technological tasks exist:

-         Continuous oxygen monitoring in range 0—10 vol. % in exhaust gases for each fuel-firing arrangement (boiler);

-         Periodic monitoring of oxygen, CO, NO_x and SO₂ in exhaust gases of fuel-firing arrangements in order to adjust their operation and/or inspection of conformance of current state to the set parameter chart.

-         Continuous monitoring of ecological emissions with calculation of gross emissions;

-         Continuous monitoring of purity of oxygen (98—100 vol. % O₂) and nitrogen (trace concentrations of oxygen in N₂) – products of oxygen separation station;

-         Continuous monitoring of purity of oxygen (0—2 vol. % H₂ in O₂) and hydrogen (0—1 vol. % O₂ in H₂) – products of electrolysis station;

And the following standard safety tasks:

-         At oxygen separation station: continuous monitoring of excess/lack of oxygen in the air of working area;

-         At electrolysis station: continuous monitoring of excess/lack of oxygen in the air of working area; continuous monitoring of pre-explosive concentrations of hydrogen in the air of working area;

-         In pulp bleaching shop – continuous monitoring of maximum permissible concentrations of chlorine in working area;

-         CHPP turbine rooms – continuous monitoring of pre-explosive concentrations of hydrogen and maximum permissible concentrations of carbon oxide in working area;

-         At plant it is necessary to have sufficient quantity of individual devices controlling pre-explosive concentrations of flammable gases, excess/lack of oxygen and maximum permissible concentrations of standard toxic gases used in production to provide workers (e.g. maintenance team) with when they are sent to hazardous areas.
