ABSTRACT
The repair of the fixed bed adsorption column, a product of arm field technical company was carried out for the purpose of bringing the faulty equipment back to its normal operating system.
Before this exercise, the equipment was out of operation because of the completely blocked base of the fixed bed column (water column) and the malfunctioning of the air control value.
The sintered bronze plate which formed the base of the water column was cleaned up and freed from debris which originally blocked the porosity of the plate to an unacceptably level. To do this, the plate was soaked in a diluted acetic acid and a current of air used to free the tiny openings from blockage. Later, the air control valve where properly reactivated, rectified and recalibrated.
At the end the operation of the equipment came back to normal functioning. The entire equipment was cleaned up and lubricated.
The fluidized bed was run and found to be in good order.
