Paper-making Industry

March 30, 2022

The pulp and paper industry, like many other industries, is restricted in many ways, such as requiring the testing of the air in the working environment to ensure the safety of workers.Moreover, the industry's growing concern about turpentine and chlorine dioxide gases requires workers to become more aware of them. The pulping process produces two main types of steam, one from the fibers of paper and the other from wood products, which are used in paints.

Turpentine is one of these chemicals, and it's not an ordinary substance because it has a low explosive limit of 8,000 parts per million (0.8%). It has a very low ignition point, at about 253.3 ° c which is lower than methane at 537.2 ℃. These properties of turpentine make it difficult to detect its vapor with conventional LEL sensors. Because the LEL sensor was originally designed to solve the problem of detecting methane levels in coal mines. Most LEL sensors use this principle when combustible gases are burned on a wheatstone bridge's catalytic beads and their heat release is detected. The temperature rise causes the resistance value to change, which is then converted to the %LEL display, so the LEL sensor is single and limited.

Otywell recommends the use of multi-gas detector, can adapt to the pulp manufacturing industry closed space detection. The built-in pump is suitable for remote sampling in a confined space. The detection of leakage gas in the environment of damp dirt can be accurate; Durability can be used in a variety of environments.
