Green Chemicals Make Life Better

Walking through the workshop every day, I deeply feel the changes brought about by the transformation and upgrading of enterprises. For projects based on 5G+industrial Internet, the vast majority of equipment startup and shutdown have achieved one-button startup, and 90% of valve operation and other links have achieved intelligent control. Patrol work basically requires no labor, and "the working environment of employees has greatly improved."

The greater changes lie in the significant improvement of the process and the significant reduction of energy consumption and pollution discharge.

In 2011, the production processes of the old factory that has been built for half a century are almost obsolete, and the labor cost is extremely high. "Using only hydrogen sulfide removal in this process, the alkali liquor desulfurization method used is unstable, requiring three to five workers in the production process, which is highly labor intensive, and also generates a large amount of waste." "Currently, wet process acid production is adopted, and the automated production line can be completed by only one person."

At the same time of manual reduction, the industrial cycle chain of the enterprise has been further upgraded, developing from traditional coal chemical industry and phosphorus compound fertilizer to fine petrochemical industry and phosphorus chemical industry. When I first graduated from college and worked in Sanning, at that time, Sanning was still a nitrogen fertilizer enterprise producing synthetic ammonia and ammonium carbonate. Currently, the enterprise has 32 categories of 68 main products, coupled with symbiosis, achieving "efficient" production. Last year, the proportion of circular economy accounted for 36% of the company's output value. "For example, the adoption of multi nozzle coal water slurry entrained flow gasification technology has a large production capacity in a single furnace and a high effective gas content. Although the investment is larger than that of a fixed bed, it has a high carbon conversion rate, liquid slag discharge, and does not generate waste water such as tar, naphthalene, and phenol. Wastewater treatment is relatively easy, achieving a fundamental transformation of the gasification device to an ecological device, promoting the transformation and upgrading of the company's industry, and reflecting green development." Speaking of today's new technologies, there is a torrent of talk.

For five years, the factory has been far away from the Yangtze River and close to home. "I feel guilty that when my wife was pregnant and had children, I couldn't come back to accompany her. Now I can go home every day and grow up with my children." Today, his favorite thing is to take a walk along the river with his family, watching the ecology of the Yangtze River getting better and better, and feeling happy.
