Description
The Equipment of Natural Gas Desulfurization by High-Gravity to Remove Hydrogen Sulfide This invention or utility model relates to a device for desulfurization from natural gas. This high-gravity equipment works on the principle of mass transfer, quickly and high selectivity desulfurization of hydrogen sulfide from natural gas. This equipment can selectively to remove hydrogen sulfide and retain carbon dioxide.
When the natural gas produced from oil associated gas and gas wells, it contains hydrogen sulfide. Hydrogen sulfide is a common gas in industrial and threat to personal safety seriously. It also causes accidents because of corrosion to pipeline. Thus, it is an important work to remove hydrogen sulfide. Nowadays, the most common method of desulfurization is using desulfurization tower.
However, there are many disadvantages in the traditional desulfurization tower, such as ineffective mass transfer, large energy consumption, immense volume of equipment and unstable operation. For the selective desulfurization, with high concentration of other acidic gas, when absorbent absorb hydrogen sulfide, carbon dioxide is absorbed the same time. Co-absorption rate of carbon dioxide is often very high, which declined the desulfurization rate. When the amine solution was regenerated, hydrogen sulfide content of the mixture did not meet the standard, which impact Claus sulfur recovery process. Moreover, the energy of carbon dioxide desorption from amine solution is higher than hydrogen sulfide.
To overcome these problems, the present invention proposes a new appliance of desulfurization of hydrogen sulfide from natural gas. The core of this equipment is using high-gravity (HIGGE) technology which was proposed by Cohn Ramshaw in 1976. This utility model has successfully used high-gravity technology in the removal of hydrogen sulfide from natural gas. The core of this technology is that it takes rapid mass transfer principle selectively to remove hydrogen sulfide and retain carbon dioxide.
The new type equipment of natural gas desulfurization by high-gravity to remove hydrogen sulfide has many advantages and essential features that will be strongly recommended to replace the traditional huge desulfurization tower.
1. The equipment of natural gas desulfurization by high-gravity can achieve very good results of hydrogen sulfide removal. For example, experiments showed that the desulfurization rate can reach more than 99 percent.
2. The desulfurization high-gravity equipment is aimed at reducing harmful gas emissions as well as reducing environmental pollution. When the amine solution was regenerated, hydrogen sulfide content of the mixture does meet the standard because there is a repetitive process on regeneration, which positive impact Claus sulfur recovery process.
Experiments showed that, recovery rate of hydrogen sulfide can achieve more than 99 percent.
3. The desulfurization high-gravity equipment alternative to traditional huge desulfurization tower that also has the advantages of smaller size and lighter weight. Moreover, the high-gravity type equipment is much easier to be operated, as well as lower comprehensive energy consumption. For instance, the equipment is convenient operated to start as well as stop, it is different from the desulfurization tower which needs 24 hours for driving start.
4. This high-gravity equipment works on the principle of rapid mass transfer and can high selectivity to remove hydrogen sulfide from natural gas. It runs smooth and steady during the work process, as well as the effective rate of mass transfer higher than the traditional desulfurization tower.
5. Using this high-gravity equipment can reduce the amount of hydrogen sulfide removal liquid. Machine will not easy be blocked by packing material, because it only produces very little foam during the operation.
Moreover, the equipment maintenance is simple. It can save the cost of renewal packing materials more than 20 times than traditional desulfurization tower.
6. For the selective desulfurization, when natural gas containing carbon dioxide and hydrogen sulfide at the same time, absorbent can highly selective to absorb hydrogen sulfide from natural gas by the high-gravity equipment, and retain carbon dioxide. Co-absorption rate of carbon dioxide is very low, which can increase the desulfurization rate.
Therefore, the HIGGE desulfurization technology has favorable potential for industrial application. The Following table displayed the essential advantages comparing with desulfurization tower in details.
