Energy saving measures for sulfur recovery equipment

Since the sulfur recovery unit produces its own steam, its energy consumption is usually negative, but it varies greatly depending on the size of the unit and the process used. The main measures to save energy include: Control the oxygen content after the incinerator to about 2%, and reduce the amount of gas as much as possible while ensuring the combustion effect. If the exhaust gas is reduced by hydrogenation, it is best to put the regeneration tower together with other regeneration units. The last point is that the boiler water uses steam condensate.

Use your own heat and use a wireless online furnace process.

Combine the steam condensate in this workshop to the deaerator and then into the boiler. Save the amount of deoxygenated water.

When production can be ensured, the inlet of the fan can be appropriately closed to save a large amount of electric energy. At this time, attention should be paid to ensuring the wind pressure. The shortcoming of the modified method is that you must pay attention to the adjustment of the air-to-air ratio and not make a big mistake, otherwise it may cause the furnace front pressure to be too low and cause an interlocking shutdown! ! ! !

It is said that the exhaust gas treatment part adopts two-stage absorption and two-stage analysis to save steam consumption, saving about 30% of steam than ordinary absorption and analysis.

An expert said, “The use of two-stage absorption and two-stage analysis in the exhaust gas treatment part can save steam consumption, saving about 30% of steam compared with ordinary absorption and analysis. ” Excuse me: I don’t understand what two paragraphs of absorption and two paragraphs of analysis mean.

The expert was talking about Scott's exhaust treatment.

It has the characteristics of simple operation and low investment in equipment. However, the hydrogen sulfide content in the purified exhaust gas is generally above 100 ppm. Especially when the CLAUS sulfur recovery operation fluctuates, the purification capacity is relatively poor. The absorption tower uses packing at both ends, the solvent is separated and the semi-lean liquid enters the tower. The tail gas enters from the bottom of the tower and is first absorbed by the semi-lean liquid and then by the fine-lean liquid. It has the following advantages:: 1. The hydrogen sulfide content in the tail gas can be reduced to 50PPM or even lower, and the total sulfur recovery rate of the device is above 99.8%. 2. The absorption rate can be very high under various circumstances. Even if there are operational fluctuations in the front sulfur recovery part, the two stages of tail gas absorption can keep the hydrogen sulfide content in the tail gas very low. 3. The combination of the two-stage absorption process and the two-stage regeneration process of the regeneration tower can also reduce the energy consumption of the device. 4. Using the non-line booster process, the pressure of the absorption tower is low and the team absorption is unfavorable. The two-stage absorption can enhance the absorption effect and make up for the impact of pressure on absorption.

Regarding the two-stage absorption and the two-stage analysis, who can upload some relevant flow charts?

May I ask why two-stage absorption and two-stage desorption can save energy? What is its energy-saving principle? Can you explain it in detail? Thank you!

In fact, it is a matter of solution concentration. If you need a high concentration of absorbing liquid, you need to use relatively more steam for regeneration. If the concentration of the semi-lean liquid can meet the absorption needs, then there will be no need for so much steam regeneration, which is relatively energy-saving!
