It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ On February 14, 2022, Sinochem Huayi Equipment Technology Co., Ltd. delivered the largest nitric acid absorption tower of its kind in Asia – the core equipment for the nitric acid production unit in Chongqing Huafeng Chemical Co., Ltd.’s project to increase the annual production capacity of adipic acid by 1.15 million tons. With a diameter of 5.8 meters, this nitric acid absorption tower was successfully loaded onto a vehicle and sent to the customer’s site, marking a successful start to the new year! As a landmark process equipment in this field, the nitric acid absorption tower requires high precision in the levelness of its trays, and the welding of the tube sheets presents significant technical challenges. The successful completion of production for this unit lays a solid foundation for the smooth delivery of the next two nitric acid absorption towers of the same size.
