The ash removal operations at the dust collector of Puyang Yongjin Chemical’s PSA plant are being carried out in an orderly manner. Author/Source: Puyang Yongjin Chemical Co., Ltd. Date: 2022-02-23. Clicks: 10. Since the dust collector at Puyang Yongjin Chemical’s PSA plant was put into use, regular ash removal operations have been conducted; to date, a relatively well-established set of procedures has been developed. At present, ash removal is carried out every Friday during the day shift. After weighing, the amount of ash unloaded this time was 68 KG, and this value was reported to the site technician for recording and statistics. This dust all originates from the adsorption tower in Zone 2 of the CO purification process. During operation, the adsorbent is carried along with the gas flow, driven by the high and low pressures, to the next stage, the decarburization zone. The accumulation of adsorbent within pipes and around valves can easily lead to improper closure of control valves, resulting in malfunctions. It can also cause abnormalities in the tower pressure, which not only poses a threat to the operation of the process but also increases the likelihood of reduced purity in the product gas, thereby having an adverse effect on the ethylene glycol production unit in the subsequent system.
