The double "leading" benchmark is refined in this way - Shandong Haihua soda ash plant green and low-carbon development exploration

Recently, Shandong Haihua Co.

"We have been deeply cultivating soda ash production for more than 30 years, taking equipment upgrading, technological innovation, energy saving, low carbon, and circular development as the direction of green factory construction, and exploring a safe and efficient, environmentally friendly, clean, energy-saving and low-carbon green chemical development path

Insist on "green and low-carbon" and do not relax

Haihua soda ash plant has achieved fruitful green and low-carbon results in recent years

The comprehensive energy consumption and ammonia consumption of light soda ash are the two core indicators

In recent years, Haihua Soda Ash Plant has explored the ecological industrial development mode of "one water and six uses, arterial expansion, vein tandem, and dynamic and static coupling" of sea (brine) water, forming an ecological marine chemical industry cluster

Playing a good "combination fist" of carbon reduction and emission reduction

Green and low-carbon development is the only way

Haihua soda ash plant took the lead in the same industry in the country to use nanofiltration membrane technology to refine underground brine instead of seawater salinization to alkali, to achieve traditional soda ash process reengineering

The plant uses calcium carbide slag instead of limestone process to apply to soda ash production, reducing stone consumption, coke consumption, reducing carbon dioxide discharge, so that the kiln top control is better than environmental standards

Up to now, Haihua soda ash plant has adopted 559 rationalization suggestions for carbon reduction and emission reduction, implemented more than 80 technical transformation projects, and successively carried out projects such as comprehensive utilization of waste sand, lime kiln dust removal transformation, distillation system optimization and transformation, magnetic levitation fan transformation, motor frequency conversion transformation, etc.

Grasp the system energy-saving "cow nose"

Building a good energy utilization system is the "bull nose"

"In the process of energy management, we will shift the focus of energy conservation and consumption reduction work from output, consumption, and process index result control to energy consumption process parameter control, sort out the pressure, temperature, concentration, and flow that affect energy consumption, and then determine all the core key points on each line, find out the upper limit, lower limit, and optimal three control points, and establish a single point assessment mechanism to achieve accurate positioning and precise control

On the basis of innovative process management, Haihua Soda Ash Plant also makes full use of advanced control systems to realize online instantaneous monitoring

"Through continuous improvement of the energy utilization system, innovative implementation of lean management, merit-based curing and a series of measures, soda ash production has increased year by year, and various consumption has been steadily reduced, especially steam consumption has dropped significantly, tons of alkali have decreased by 30 kilograms year-on-year, and the annual standard coal has been 2658 tons, reducing consumption and increasing efficiency by more than 10 million yuan
