Report by our newspaper’s reporter Mei Liaoying, with contributions from correspondent Hu Haiyan: Recently, two more utility model patents were granted for the catalytic gasoline desulfurization unit (S-Zorb) at Zhenhai Refining & Chemical Co., bringing the total number of patents held by this unit to 3. The S-Zorb unit is an important device for improving the quality of gasoline. Zhenhai Refining & Chemical Corporation built and put into operation two S-Zorb units in 2009 and 2014 respectively, which possess the highest processing capacity among similar units in China. Due to the complex production control processes and numerous interlocks, the operational lifespan of similar units in China is not long. Zhenhai Refining & Chemical organized its technical staff to work on this issue, and in April 2013 it was granted a patent for the \"Modification of the horizontal tubes in the reactor receiver of the S-Zorb unit,\" which improved the unit’s ability to operate over long periods of time. In March this year, two utility model patents were granted for the technologies titled \"Energy-saving optimization methods for the regeneration system of the S-Zorb unit\" and \"Installation of loose ring pipes in the expanded section of the S-Zorb unit’s regenerator to prevent adsorbent accumulation and caking\", providing solid support for the stable, efficient, and continuous operation of the unit.
