Huaihua Chemical Group Company in synthetic ammonia plant is an annual output of synthetic ammonia, 36 million tons of large-scale chemical enterprise, coke, Shanxi Yangquan seed coal as the raw material for the preparation of semi water gas, tannin, PDS mixed method of atmospheric desulfurization, with two sets of desulfurization and filler are used in bulk packing. Switch to the Hangzhou Huana towers Separation Engineering Co., Ltd. plastic grill packing, after seven months of production practice tower found no sulfur paste fill in the grid plate between deposition resistance does not increase to ensure stable production for a long period, achieved better investment economy effect.
The operation of the equipment before reform

The phi 6000 desulfurization system is to apply for device, of the interior of the tower body disrepair, lower corrosion is serious, replace the lower part of the tower body is in short time to complete, scattered packing channeling and eddy current phenomenon exists in the operation process, long-term operation of gas-liquid easy to drift, sulfur paste easily attached on top, so that the resistance rise, desulfurization efficiency decline, decline in synthetic ammonia production, the rise of consumption, for normal production impact. Especially the following corrosion problem, become a major security, if measures are not taken, once corrosion is accelerated, to a lesser extent, affect the production, severe cases can lead to severe accidents. The above two factors, decided on a new tower; before the transformation of the operation with 6000 towers are as follows:
