Recently, with the power transmission, rising current, chlorine and hydrogen gas analysis qualified and successfully connected to the grid, the current is gradually rising. The completion of a series of work and qualified indicators indicates that the second phase of Ningxia Huayu 290000 tons of ionic membrane caustic soda relocation project has opened up the whole process and achieved a successful start-up. & nbsp

Prepare to drive with one heart and one mind and go all out

The project is a key relocation project of Suhua Group, with a total investment of 1.104 billion yuan, and construction will start in July 2019. Huayu Company is building while producing. After COVID-19 's epidemic situation, changeable market environment and extreme weather troubles, all staff fully carry forward the Huayu spirit of "tenacity, dedication, innovation and cooperation" and adopt the work mode of "party building + project construction". A "project vanguard" led by Gu Jiali, secretary of the party general branch and general manager, has been set up to coordinate all parties, concentrate efforts, and make every effort to promote the project construction. And in September 2021, the first phase was successfully driven and successfully put into production. In March this year, the second phase of the project turned to the preparatory stage of trial production, and the company set up a start-up headquarters and was deeply involved in on-site management, co-ordinated and coordinated, solved the problems existing in the project in time, and made every effort to promote the work of "three checks and four decisions". Successfully completed the installation task. The company organizes the manager's office and various functional departments to carry out the inspection of start-up preparation, which provides a strong guarantee for the smooth start-up of the device.

Go all out

In April this year, the electrolysis plant turned into the stage of preparation for start-up, and the leaders of the company and the project team of the group went deep into the site to coordinate and coordinate all parties' forces and materials to solve the problems existing in the start-up process in time. The electric instrument workshop is responsible for the commissioning and commissioning of the 110KV main transformer and rectifier, as well as the commissioning and guarantee of instruments, automatic control equipment and systems. The whole staff of the caustic soda plant went to battle in turn, day and night, regardless of hardships, from on-site sanitary cleaning and equipment debugging to pressure testing and leakage testing, pipeline cleaning, construction monitoring, and then to operation monitoring, itinerant inspection, debugging operation, parameter adjustment, post operation method compilation. Go all out to do every job that you are ready to drive.

From April to early May, it successively passed the processes of lightning protection electrostatic grounding detection, fire control acceptance, expert evaluation of trial production plan and reporting.

They perform their duties in a tense and orderly manner on the day of driving.

From the intermediate control adjustment of the liquid level such as hydrogen chloride pressure and secondary brine, to the start of the cycle of the electrolytic cell according to the instructions of the general command on the spot, and then to the electrical confirmation of the normal operation of the rectifier, the central control confirms that the power supply, the voltage stability of the cell, the normal operation of hydrogen and chlorine treatment, and the interlock input …... The system debugging is carried out in an orderly manner. The company leader follows the dispatching command throughout the process, keeping a close eye on the operating conditions and various process parameters; the staff of the caustic soda plant stick to the on-site posts to deal with sudden failures in time to ensure the stable operation of the device, and the busy figure shuttles back and forth in each debugging site; production Management Department, Safety and Environmental Protection Department, Engineering equipment Department and other functional departments sent backbone personnel to escort the commissioning and driving of the electrolytic plant. With the chlorine and hydrogen systems connected to the grid, it marks the successful commissioning of the 90,000-ton ionic membrane caustic soda project!

The commissioning of the second phase of the 290000 ton ionic membrane caustic soda relocation project is the key, hope and staying power to promote the development of the company. The hydrogen and chlorine produced will further expand the width and depth of radiation of chlorine and alkali products, and successfully expand production. It also provides a strong market guarantee for the follow-up sales layout, which will be more conducive to promoting the market pattern inside and outside the province and occupy the absolute dominance in the region. Further improve the comprehensive competitiveness of the company's product sales, and further maintain and increase the value of state-owned assets. At the same time, the 100000 tons / year caustic soda and 75000 tons / year caustic soda matching equipment projects currently under construction are of milestone significance for the adjustment of the sales product structure of the group, the promotion of resource conservation and utilization, and the construction of resource recycling industry system. In addition, this start-up electrolysis device also undertakes the important task of testing the practicability of the company's domestic electrolytic cell and home-made ionic membrane transformation, which can be described as new equipment, new technology, new appearance, new level and new achievements.

No struggle without Youth & nbsp

The successful start-up of the second phase of the 290000 ton ionic membrane caustic soda relocation project is a vivid practice of Suhua Group in transforming the subject education and learning achievements into promoting the high-quality development of the enterprise, which will also be a milestone in the new journey of Huayu in Ningxia. It will strongly optimize and improve the quality and efficiency of production and operation, maximize device profits, broaden the development of enterprise industrial chain and improve market competitiveness. Help Ningxia Huayu to achieve higher quality development. Source: Huayu Chemical Industry, Ningxia
