Features of the new area denitrification system (1) Key equipment for the denitrification system The bottom part of the electrorefining and settling tank body material for contact with the tail oil (the lower head and the 600mm high cylinder connected to it) is 316L, and the other part is 16MnR. This is similar to the domestic one. The electro-refining settling tank material of the device is all 316L, and the manufacturing cost is reduced by about 40%, and it fully meets the production requirements. (2) The denitrification agent tank and the tail tank are all made of 16MnR lining epoxy resin. From the operation condition, the antisepsis requirements of the process are met (the control use temperature does not exceed 100e), and the two cans of the same type of equipment in China are all 316L, higher cost. (3) The denitrifying agent unloading pump and the tailing oil loading pump share a single screw pump, which not only reduces the investment in equipment, but also reduces the area occupied by the pump. It is more appropriate to limit the newly added land for the technical transformation project. (4) Because of the low freezing point of the denitrification agent (not higher than 20e) and the low winter temperatures in northeast China, the denitrification system uses steam and hot water heating along with heat, which can be flexibly adopted according to the requirements of pipeline media and changes in ambient temperature. Hot water or steam heating method.

Denitrification agent The WSQ-2 denitrification agent used in this denitrification system is produced by Wuhan Hannan Jinhe Petrochemical Co., Ltd. Operation and analysis of the denitrification system 3.1 The properties of the denitrification feedstock and the changes of alkali nitrogen and sulfur before and after denitrification The denitrification system was put into operation in mid-November 2000. In order to reduce the denitrification efficiency of the second-line HVI150 oil with different agent oil ratios, the denitrification rate is 63% under the condition of agent-to-oil ratio 1B451, and the total denitrification rate after refining with white clay is about 74%; the agent-oil ratio drops to At 1B485, the denitrification rate is about 49%. After the purification of white clay, the total denitrification rate reaches about 70%. The total denitrification rate is reduced by about 14% compared with the denitrification effect of the agent to oil ratio 1B451, and the base oil rotates oxygen bombs. Only 5 min above the control index, it can be considered that when the raw material of alkali nitrogen [email protected], 1B485's agent to oil ratio is close to the minimum addition of nitrogen removal agent. From the total nitrogen removal effect, the proportion of white clay added to 1.04% is also near the minimum.

Magnetic Business Card

1. Use a photograph of a local landmark
Tap into your customers` local pride by including a photograph of a local landmark. Just make sure you take the photograph yourself or have the photographer`s permission to use it.
