Feasibility Report on Chain Control

Since you have a good understanding of the factory’s manufacturing processes, you must be proficient in its control methods as well – you studied Zidonghua, right! Could you introduce the level of automation in your factory at present? Why does your boss ask you to prepare a feasibility study? Maybe the boss has his own reasons for that – do you know them? If you ask yourself a few more \"whys,\" things won’t be as difficult as you think. As for feasibility reports, just do a quick search online and there are many available.

It can be considered in terms of cost savings, reduction of labor resources, and improvement of product quality.

Our factory has no form of centralized control at all; its technological level is quite backward – it still uses processes that were introduced from the Soviet Union over 30 years ago. This is the case everywhere in the country. Most of the raw materials are strong acids or strong bases, which are highly corrosive to instruments. Sampling for monitoring is done frequently, with samples taken from almost every tank for analysis. Both raw materials and finished products contain powdered substances that require manual feeding. The quality of the employees is very low, which is really frustrating! The chief engineer is stubborn; he insists on using very basic methods for measuring levels, such as using a stick to do so – how innovative!

I believe that preparing a feasibility study is an important step in engineering construction and project renovation. I think it can be approached from the following aspects: First, process introduction – gaining a thorough understanding of the process and knowing where control measures are applicable； II. Basis and principles for preparation III. Background to the proposal of this plan IV. Analysis of the reliability and necessity of investment V. Introduction to the control plan along with relevant regulations and requirements (this is the key part; a detailed explanation of the control system and instruments is necessary) VI. Safety and reliability analysis, as well as environmental assessment VII. Preliminary estimate of investment costs VIII. Conclusions of the feasibility study Actually, those who work in design firms should know more about this than I do; I’m just trying to share my knowledge here.

I currently work at a chemical engineering institute, where I am involved in the design of automatic control instruments. I have just completed a feasibility study report on automatic control. Below is an excerpt from the section on automatic control in that feasibility study report: 4.4 Automatic Control 4.4.1 Overview (Explain the requirements for automation in the production process; take into account the level of automatic control in similar facilities both domestically and internationally, as well as the investment requirements for the project and the needs of the production process, in order to determine the appropriate level of automation for the project to be constructed.) For renovation, expansion, and technical upgrading projects, it is necessary to describe the existing level and condition of the enterprise’s automation systems, and take these factors into account along with the newly installed equipment.) 4.4.2 Selection of control systems (brief description of the principles for selecting control systems) ； Describe the composition of the control system, its basic configuration, functional requirements, and technical specifications ； The control system should include safety instrumented systems as well as production management systems, which will be explained separately ； For large integrated facilities, the control system configurations should be described separately for each facility; similarly, the control systems for utility systems, auxiliary production facilities, storage and transportation, and fire protection are also explained individually ； For control systems that need to be introduced, the reasons and scope for such introduction should be specified.) 4.4.3 Instrument selection (selection principles) ； General requirements for instruments ； List the types of instruments according to F, L, P, T, A, V, etc., indicating the applicable scenarios and media. 4.4.4 Control room layout (Describe the arrangement of the control room based on the project’s configuration, including its size, location, and dimensions.) 4.4.5 Instrument power and gas supply (Requirements and specifications for power and gas supply.) 4.4.6 Safety technical measures (Safety safeguards for the control system; devices with special requirements should be described separately.) 4.4.7 Standards and codes (List the main domestic and international standards and codes used in the design, along with their names and standard numbers.) PS: This is the general structure; it can be adjusted according to different circumstances. Waiting for the moderator to give points; it’s so tiring to type so much! :lol

Thank you all for your valuable insights. During the discussion, please feel free to share your opinions.

Thank you all!!!!!:victory: :victory: :victory:

The approach used on the 7th floor is that of the design institute, with the preparation of the feasibility study being carried out by several specialized teams. wxz_9999 is a relatively comprehensive and complete approach. However, if it has to be done in a factory, it can’t be too detailed, as there is no relevant expertise available to assist. Perhaps the poster should propose reasonable suggestions for automation, so that only the level of automation and the main control schemes need to be specified, along with the determination of instrument types and the selection of key instruments. As for the budget, let the boss decide.
