Dare to take "porcelain live" take the hot "cold bench" Southwest Oil and Gas Field desulfurization technology among the best in the world

He Jinlong and colleagues spent more than three years to nurture the baby - "big hole alumina" sulfur recovery catalyst, was designated as China Southwest Oil and Gasfield Company West China International Exposition on the show. He Jinlong said happily. "The Mid-Autumn Festival moon cake sent to us is big enough."

The "macroporous alumina" sulfur recovery catalyst is one of the catalysts for the conversion of hydrogen sulfide to sulfur. Compared with the "predecessors" that have been widely used, the sulfur recovery catalyst has the advantages of strong impact resistance and long service life. Compared with the most advanced similar products in the international market Performance, price cheaper. After the Mid-Autumn Festival, PetroChina Southwest Oil and Gasfield Company started to promote this new product for domestic use.

Natural gas desulphurization technologies, including solvent absorption of toxic substances in natural gas - sulfur and hydrogen, solvents and hydrogen sulfide separation, hydrogen sulfide into sulfur sulfur recovery technology. Sichuan Basin is the starting point for the development of natural gas in China. It is also the birthplace of natural gas desulfurization technology. In December 1965, the first natural gas desulfurization plant in China was built. Due to the technical difficulties and complicated market demand, PetroChina Southwest Oil and Gas Field Company is the only enterprise in China to develop and provide a full range of desulfurization technology and various solvents and catalysts.

During the "12th Five-Year Plan" period, PetroChina Southwest Oil and Gasfield Company has developed a series of sulfur recovery catalysts which have reached the international advanced level and possess independent intellectual property rights. Monitoring data show that the application of "titanium-based sulfur recovery catalyst", organic sulfur hydrolysis rate of over 96%, a substantial increase in sulfur recovery; application of "low temperature hydrogenation hydrolysis catalyst" to save fuel and power production costs 30%, significantly reducing production costs. Chongqing, Sichuan, Gansu and other places more than 40 sets of sulfur recovery unit, the industrial application of these two catalysts more than 500 tons, an average annual reduction of 6,000 tons of sulfur dioxide emissions.

In the sulfur recovery technology, PetroChina Southwest Oil and Gasfield Company has also developed a new catalyst such as "water-based complex iron", "sulfur dioxide catalytic adsorption regeneration" and other new technologies, sulfur recovery technology based on this significant difference compared with the traditional technology , The entire set of technology into the ranks of the international advanced level.

PetroChina Southwest Oil and Gas Field Company continued to study and absorb natural gas hydrogen sulfide solvent, but also made more new achievements. Among them, the "selective desulfurization solvent" and other solvent system performance indicators, reached the international advanced level, widely used in the development of northeastern Feixianguan Group gas reservoir, Sichuan Longwangmiao gas reservoir desulfurization plant

Particularly gratifying is that for the long-term problems that bubbles in sour natural gas are blown in a specific environment and seriously affecting the separation effect between natural gas and hydrogen sulfide, PetroChina Southwest Oil & Gasfield Company has developed "impurity removal" technology through precise research And solvent, not only broke the monopoly of foreign technology, but also eliminates the foreign solvent "hydrogen sulfide after resurrection deteriorating" phenomenon.
