Development of a method for continuous monitoring of the performance of a two-stage filter with the placement of cylindrical filter cassettes of preliminary and fine cleaning in one housing

The existing gas practice does not have data on continuous monitoring of the performance of a two-stage filter with cylindrical filter cartridges of preliminary and fine cleaning placed in one housing. As a result, the safety of the gas equipment installed behind the pressure regulator is reduced. The calculated expressions for determining the limiting values of pressure losses and productivity of two-stage filters with placement of cylindrical filter cassettes of preliminary and fine cleaning in one housing are obtained. When these limits are reached, the gas supply is automatically switched to the filter located on the backup reduction section. The paper also proposes a scheme for constant monitoring of the limiting values of pressure losses and productivity on two-stage filters with the placement of cylindrical filter cartridges of preliminary and fine cleaning in one housing. The developed scheme automatically turns on the gas supply to the backup filter and informs the dispatching service and maintenance workers wirelessly when the maximum values of pressure losses and productivity are reached.
