Effect test

Embodiment 1

[0012] Sodium dodecyl sulfonate 40%

[0013] Sodium tripolyphosphate 10%

[0014] Vegetable oil 20%

[0015] Cobalt Dimer Sulfonated Phthalocyanine 15%

[0016] Sulfonated Salicylic Acid 15%

[0017] Add ammonia water and stir to fully dissolve, then add to the system. This embodiment is tested in a simulated experimental device. An average of 0.5 kg of compound tower cleaning agent is added per cubic meter of system solution, which can effectively reduce the blockages such as sulfur deposited on the bulk packed tower, thereby reducing the tower resistance.

Embodiment 2

[0019] Sodium dodecylbenzenesulfonate 30%

[0020] Sodium tripolyphosphate 20%

[0021] Vegetable oil 30%

[0022] Cobalt Dimer Sulfonated Phthalocyanine 10%

[0023] Citric acid 10%

[0024] Add to the lye, heat and stir to fully dissolve and then add to the system. This embodiment is tested in a simulated experimental device. An average of 0.5 kg of compound tower cleaning agent is added per cubic meter of system solution, which can effectively reduce the blockages such as sulfur deposited on the bulk packed tower, thereby reducing the tower resistance.

Embodiment 3

[0026] Sodium dodecyl sulfonate 35%

[0027] Sodium pyrophosphate 15%

[0028] Propylene glycol polyether 20%

[0029] Cobalt Dimer Sulfonated Phthalocyanine 15%

[0030] Sulfonated Salicylic Acid 15%

[0031] Add to the lye, heat and stir to fully dissolve and then add to the system. This example is actually applied in a synthetic ammonia production enterprise in Shandong. An average of 0.5 kg of compound tower cleaning agent is added per cubic meter of system solution. Under normal production conditions, it takes ten days to reduce the tower resistance from 70 mmHg to 35 mmHg. about.

Abstract

The invention relates to a high-efficiency multi-element composite tower cleaning agent. The agent is composed of 30-40% of a penetrant, 10-20% of a dispersant, 20-30% of a surface tension regulating agent, and 20-30% of effective component auxiliary agents. The operation is simple. The agent is dissolved in lye, and the solution is directly added into a system. Machine stopping and output reduction are avoided. The tower cleaning agent is environment-friendly. With the tower cleaning agent, the tower resistance of a desulphurization tower can be rapidly and effectively reduced, and the blockage in the tower can be removed.

Description

technical field [0001] The invention discloses a formula of a high-efficiency multi-component composite tower cleaning agent, which can be widely used in the reduction of tower resistance and removal of tower blockages in desulfurization towers of process enterprises for removing hydrogen sulfide through wet oxidation. Background technique [0002] At present, the wet oxidation desulfurization process is mainly used to remove hydrogen sulfide from gas in China. Due to the technical limitations of this process, as well as other reasons caused by high impurity content in the raw gas and improper operation, the desulfurization tower has risen tower resistance and tower blockage after a period of operation, resulting in the company having to stop Pagoda cleaning causes a lot of waste of manpower and material resources, reduces production of enterprises, increases investment in sewage treatment, and causes heavy economic losses to enterprises. It has become an urgent problem to b...
