Recently, three entrusted development projects of refining catalyst unit jointly undertaken by Tianhua Institute and partners have passed the evaluation of scientific and technological achievements.
China's refining catalyst has its own unique technology and production system, various types of refining catalyst have formed a series, the technical content is almost the same as that of foreign catalysts, and has its own advantages. Tianhua Institute has successfully developed various key equipment for catalyst preparation, such as blade pre drying, rotary flash drying, electric heating baking furnace, gas baking furnace, air flow drying, blending, etc., and successfully realized industrial application.
With the continuous improvement of catalyst preparation process requirements, energy consumption, waste gas emission and cost of the unit become the factors restricting the development of catalyst preparation technology. The three projects rely on the 50000 T / a FCC catalyst unit of Changling branch of Sinopec catalyst Co., Ltd. as the largest FCC unit in China, under the premise of ensuring product quality, the project The purpose of R & D is not only to enlarge the existing technical devices step by step, but also to realize the innovation and upgrading of devices based on energy saving, consumption reduction and environmental protection.
Among them, the "FCC catalyst large spray drying and mixing equipment technology development" project has developed a new type of high temperature, large volume and energy saving spray drying equipment, and the semi open cycle technology has been used to recycle the heat of the exhaust hot air, so as to achieve the goal of reducing heat loss and reducing exhaust emissions. "Large scale design and development of gas fired roaster" effectively improves the loading system and thermal efficiency; "molecular sieve drying roasting system engineering optimization and comprehensive energy saving technology" has developed a molecular sieve drying roasting external circulation and internal circulation technology, which can not only reduce energy consumption, but also reduce the subsequent tail gas treatment system load, playing a key role in improving the system stability.
At present, these three technologies have been applied in the customer's site, the product quality meets the requirements, the device operates stably and achieves the expected effect, and also realizes the purpose of energy consumption reduction, tail gas heat recycling and tail gas emission reduction. Other related technologies such as waste water heat pump rectification ammonia removal technology, spray drying and tail gas comprehensive utilization are also in continuous development, application and assessment.
In response to the original ecological goal of vigorously promoting green environmental protection and energy saving development, Tianhua Academy's three scientific and technological development projects, through technological optimization and innovation, not only create good economic benefits for customers, but also bring good social benefits for chemical enterprises committed to building green mountains and rivers due to its outstanding efficiency in the field of energy conservation and environmental protection.
Tianhua academy is customer-oriented, focuses on scientific research and innovation, and is committed to providing customized and all-round overall services for customers. It is committed to becoming an integrated technology and equipment solution supplier integrating technology and equipment research and development, design, manufacturing and after-sales services. Over the years, Tianhua academy has been constantly exploring and developing in the aspects of innovation mechanism, innovation team construction, technology accumulation and reserve, technology innovation output and benefit, and has achieved fruitful results.
At the recognition conference of China Petroleum and Chemical Industry Federation recently concluded, Tianhua institute won the honorary title of "technological innovation demonstration enterprise" of China Petroleum and chemical industry in 2019. At the same time, Tianhua Institute participated in the research and development of "green and efficient million ton ethylene complete technology development and industrial application" and "key technology of welding shape control for the intrinsic safety of major pressure equipment" respectively won the special prize and the first prize of science and technology progress issued by China Petroleum and Chemical Industry Federation.
Tianhua Institute, founded in 1958, is one of the first batch of units engaged in chemical equipment research and the only professional non-standard chemical equipment comprehensive research institution in China. It has 15 national professional committees, 3 national standards committees and 2 core journals. It has established the national drying technology and equipment engineering technology research center and the national local federation of chemical process energy conservation and environmental protection technology and equipment Two national innovation platforms of HEC. It has 421 patent authorizations, 188 national and industrial standards, more than 40 national awards and 211 provincial and ministerial awards.
In the future, Tianhua academy will continue to give full play to its scientific and technological innovation and technological advantages, and make greater contribution to the development of China's chemical equipment manufacturing industry through innovation driven and industrial layout with the vision of being an excellent national brand.
