Pentane Gas Detection and Alarm System

Filler materials made of Expanded Polystyrene Foam (EPS - Expanded Polystyrene Rigid Foam) are used in the boxes to transport the products without damage, especially in the sectors that manufacture electronics and white goods.

EPS manufacturing is generally carried out by the companies themselves due to the difficulties in the transportation processes of the products and the increase in the general expenses in the production processes outside.

Expanded Polystyrene Foam (EPS - Expanded Polystyrene Rigid Foam) is a typical white colored thermal insulation material in the form of foam, with closed pores, obtained from petroleum.

In the production of EPS (Expanded Rigid Foam) products obtained by inflating and fusing polystyrene particles, pre-heating of polystyrene raw material, which is primarily called bead type, injected with N-Pentane (inflating gas used to inflate the particle structures and produce foam), with steam After the drying and maturation processes are made, molding processes are carried out to ensure that the particles are tightly fused with each other. After N-Pentane gas provides the formation of many small pores in the particles, it is replaced by air in a very short time during and after production. Stagnant air is trapped inside the closed porous cells within the EPS plates. By replacing the inflating gas with air in a very short time, it ensures that the desired volume remains constant.

The most important safety risk that may arise in all these transportation, storage and manufacturing stages,

It is the flammable feature of EPS. This situation can be attributed to the flammable vapors that arise due to the expansion agent, Pentane contained in the particles. Pentane may contain 3% - 8% concentration in the grain, depending on the raw material. Pentane has a flash point of -50 ° C and a boiling point between 34 ° C and 36 ° C. Pentane vapors are colorless and their relative density is about 2.5 times that of air and heavier than air. The flammability range is between 1.4% lower explosion limit and 8.3% upper explosion limit, depending on airborne concentration. Since pentane vapor is heavier than air, it will be collected in the lowest areas of the enterprise. All business areas should be constantly ventilated. When not ventilated, it can accumulate in all spaces in all spaces. Pentane, as a typical expansion agent, can be exposed at any time, starting from the stock stage, including the conditioning stage after the transportation and even the production of the final product. In case of accumulation of pentane vapor in electrical equipment, static electricity discharges and possible ignition areas such as cutting and welding, where there is a potential for hot work, flammability and potential fire risk occurs. For this reason, it is necessary to prepare scenarios for the detection and evacuation of gas at every stage of the EPS process.
