The researchers are experimenting with refining the product.

Recently, Xiaobian visited Hunan Solar  Chemical Co., LTD. (referred to as Solar Chemical), located in Songmu Jingkai District, scientific researchers are conducting product purification research and development test.

"Our company is the world's largest triazole manufacturer, triazole annual design capacity of 10,000 tons, product sales account for 60% of the country, 40% of the world." Xiao Xiao, assistant general manager of the company, Solar Chemical was formerly Hunan Sun Plant Resources Co., LTD., in order to implement the national dangerous enterprises "move into the park" policy, and the whole move to the pine open zone.

As a small giant enterprise in Hunan Province, Xiangshuo Chemical has three invention patents, such as "Recycling Method of triazole by-product ammonia Water" and five utility model patents, such as "a plugging device in the distillation process of new pentadiol". Among them, the project of "Development of sodium triazole synthesis technology" won the third prize of Hunan Science and Technology Progress Award, and the project of "Industrialization of recycling of ammonia water and circulating mother liquor of triazole" won the second prize of Hunan Science and Technology Progress Award.

The production of triazoles is known to produce by-products of ammonia. If the by-product ammonia water is not recycled, it will not only waste resources, increase production costs, but also affect the surrounding ecological environment. To this end, Solar Chemical and Hengyang Normal University cooperation research and development of the "triazole ammonia by-product and recycling mother liquor recycling" new process, recovery of ammonia by-product and purification, and then as energy saving and environmental protection products, sold to coal production enterprises, for desulfurization and denitrification. The operation of the new process not only realizes the requirements of energy conservation, emission reduction and cleaner production of Solar Chemical, but also will generate 1.5 million yuan of income for the company every year.

"We not only pursue energy saving and emission reduction in the production process, but also strive for excellence in equipment configuration. The same meter of pipe, made of today's material, costs four times as much." Stepping into the production plant, stainless steel tanks, pipes and floors come into view. Xiao Xiao said, as a relocation into the park enterprise, Solar chemical environmental protection equipment than before has made considerable progress: the use of stainless steel storage tanks and pipelines, can prevent "running and dripping" phenomenon; Stainless steel floor, not only can avoid by-product ammonia leakage into the ground, but also can focus on recycling, processing scattered products; Install ammonia absorption tower to eliminate the unorganized discharge of ammonia gas; Previously, the organized discharge of ammonia gas only went through secondary recovery, now it needs to go through tertiary recovery...

All critical chemicals under supervision are equipped with dual level alarms, which are linked to independent safety instruments (SIS). In case of emergency, the feed pump can be cut off.

Construction began in 2017, equipment installation began in June 2018, and equipment purging, cleaning, pressure test and cold test started in August 2019. Solar Chemical has now entered the stage of single test.

"Thanks to the" five one "joint point mechanism of the pine open area, timely and efficient to help us solve the problems of land expropriation, demolition, procedures and so on, so that the project in a year and a half to promote quickly." Xiao Xiao told Xiao Bian, pine open area has also helped enterprises strive for manufacturing strong provincial major industrial projects special funds and Hengyang City small and medium-sized enterprise development special funds, a total of 1.3 million yuan. "We will put into production as soon as possible, achieve production and efficiency, and gradually do better, stronger and bigger, to make contributions to the city's economic and social development."
