2017 Work Summary: Sulfuric Acid Plant Construction Another year has quietly passed by in the midst of busy activities! Before I knew it, I had been working at the second-phase project department of Anhui XX Renewable Resources Technology Co., Ltd. for over 8 months. My main responsibilities there were related to the installation and construction of sulfuric acid and desulfurization projects. With the proper guidance of the department’s leadership and the strong support and cooperation of my colleagues, I was able to successfully complete all the tasks assigned to me in 2017. As the end of the year approaches, in order to summarize the past and work better in the future, a summary of this year’s work is as follows: I. In terms of ideological quality: To carry out all aspects of project construction more effectively, it is necessary to continuously improve one’s knowledge and capabilities. I have studied a large number of books and documents on topics such as the Contract Law, Chemical Engineering Design Guidelines, Sulfuric Acid Design Manual, Project Management, Equipment Management, and Project Engineering Management. Secondly, one must possess a strong sense of professionalism and responsibility, approach tasks with seriousness, and act with integrity. Whether or not instructed by superiors, one should prioritize work, clarify the procedures and approaches, and complete tasks efficiently. Third, one must have a strong sense of teamwork, work together with colleagues, and be willing to help others. Regardless of who it is, one should unconditionally cooperate in anything that benefits the work, and take pleasure in sharing experience and skills. Fourth, strictly abide by all the company’s rules and regulations: do not be late, do not leave early, do not miss work, and follow the proper procedures to request leave when necessary. II. Technical Aspects of Operations 1. Coordination regarding environmental impact assessment, safety assessment, and energy assessment documents: To enable the project to start construction sooner, extra hours were worked to assist relevant departments in compiling and revising these assessment documents, ensuring that all evaluations were approved smoothly. 2. Determination of the acid production process route and product specifications – Since the conditions in the side-blown oxidation furnaces used in the recycled lead industry are not applicable as a reference, what are the conditions of the flue gas? No one can give a definite answer ； Through multiple discussions and exchanges with experts from the metallurgy and sulfuric acid industries as well as design institutes, the SO2 concentration was ultimately determined to be 5.22% (on a volume percentage basis). Based on industry experience, this concentration might be on the low side; after consultations among experts, the sulfuric acid production process was finally decided to be one that involves closed-system dilute acid washing, followed by absorption and desulfurization using organic amines. Given the characteristics of the industrial park, there are many manufacturers that produce lead-acid batteries. These companies require 80,000 tons of AR acid per year. Based on this information, two product options have been proposed: 98% industrial sulfuric acid and refined AR sulfuric acid. To produce as much AR acid as possible, a chilled water cooling process was designed into the purification stage to ensure an annual production volume of AR acid of no less than 40,000 tons. Therefore, flue gas conditions will be an important influencing factor for this project, as well as a challenging one. We will make every effort to focus on how to build high-quality projects and achieve clean production, paying close attention to all details to ensure the smooth commissioning of the projects. 3. Selection of flue gas desulfurization method: As environmental protection requirements become increasingly stringent, environmental compliance is a matter of absolute necessity; therefore, strict standards must be applied from the design stage. To ensure that flue gas meets environmental regulations, various desulfurization methods were examined one by one. Taking into account the specific conditions of this project, an organic amine-based, renewable flue gas desulfurization method was chosen. This approach not only helps meet environmental standards but also creates favorable conditions for increasing the SO2 concentration needed in acid production, thus achieving multiple benefits at once. 4. Tendering for sulfuric acid and desulfurization projects: In accordance with the requirements of these projects, more than a dozen bid documents were prepared, and over ten on-site tender meetings were held, during which technical questions were addressed and various proposals were evaluated. Significant efforts were made to determine the winning bidder. 5. Inspection of equipment suppliers: After the tendering process was completed, visits were made repeatedly, day and night, to sulfuric acid and desulfurization equipment suppliers across the country. By examining the performance of each bidding party, the final winning bidder was identified. 6. Preparation and review of the technical agreement and draft contract for the flue gas desulfurization and sulfuric acid production project: Once the winning bidder is determined, a draft of the technical agreement and contract is prepared for the project in question; these drafts are then reviewed, revised, and re-reviewed together until a final version that meets the requirements is achieved. 7. Review of engineering drawings for flue gas desulfurization and sulfuric acid production. To ensure the smooth progress of the construction of sulfuric acid and desulfurization facilities, the review of drawings is a crucial step in the project development process. We consulted experts, design firms, construction companies, and colleagues to carry out thorough reviews, making adjustments to the drawings as issues were identified; in total, there were 6 such revisions. The purpose of these reviews is to ensure that the project progresses smoothly, that the facilities can be put into operation efficiently, and that operation and maintenance are simplified. 8. Civil engineering compliance review: It is crucial to verify that the equipment is positioned accurately before beginning civil engineering construction. Every drawing related to civil engineering is carefully reviewed, and any issues found are corrected promptly to ensure accuracy. 9. Communicate and liaise with equipment suppliers: Keep in regular contact with them to obtain information regarding the production of the equipment, ensure timely delivery of the same, and guarantee that the project progresses as scheduled. In short, a year’s work can be summarized as follows: 1. One must use one’s brain more in work, think of solutions and ideas, be diligent in thinking, and enhance the initiative, foresight, and creativity in one’s tasks. 2. One must be careful and meticulous in work, starting with small tasks; the work should be carried out with precision and attention to detail, ensuring that no tasks assigned by the supervisor are delayed due to negligence. 3. In work, one must distinguish between primary and secondary tasks, as well as what is urgent and what isn’t. 4. Strengthen learning, make full use of time, and be eager to learn; integrate learning with one’s own work, study earnestly, and engage in broad-based learning. Summarize in study, improve through practice. 5. Strengthen one’s moral cultivation by adhering to the company’s new standards and requirements, and hold oneself to strict standards. Be diligent and pragmatic in one’s work, and exercise self-respect, self-reflection, self-discipline, and self-motivation while at work. 6. In addition to striving to do one’s job well, it is necessary to acquire more professional knowledge, continuously improve oneself, and enrich and perfect one’s skills. Although I have achieved certain results over the course of this year’s work, there are still some shortcomings: 1. I do not pay enough attention to details; some detailed tasks are overlooked. 2. When I am very tired from work, my focus wanes. 3. I cannot use CAD, which sometimes affects my work. III. Work Plan for 2018 1. Cooperate with the construction unit to ensure proper progress of the project. Organize the construction work in line with the project schedule, have the construction unit prepare weekly, ten-day, and monthly progress plans, and monitor the progress achieved. Identify the reasons for any delays, and accelerate progress while maintaining quality, so as to ensure the smooth completion of the installation work. 2. In accordance with the project schedule, hold project coordination meetings in a timely manner. Based on the project schedule, conduct construction meetings on Mondays for planning and on Fridays for summaries, ensuring that all issues are identified and resolved promptly. Everything is taken care of, and every task is carried out. 3. Develop plans for individual unit testing and integrated testing. Based on the installation conditions of the project, and in collaboration with the equipment suppliers and installation teams, carry out tests on each individual unit as well as integrated testing to ensure that the project can start operating successfully from the first attempt. 4. Develop a training plan: In collaboration with the equipment suppliers and installation teams, a corresponding training plan should be formulated to ensure that each operator has a thorough understanding of the equipment’s structure, performance, functions, operational principles, processes, startup and shutdown procedures, as well as operating guidelines. This will enable them to operate the equipment skillfully, thus preparing the necessary personnel for smooth operation. 5. Driving and operation management: Establish various production management systems to ensure steady and orderly production. Acid Production Engineer: Pei Qinghua, December 20, 2017
