Generally, which area accounts for the largest investment in project budgets?
Thread Content
In terms of engineering projects, regarding the aspects covered in this section, which area involves the largest investment?
It must be the system, especially the imported ones. Anything imported isn’t cheap.
Instrumentation equipment and operating systems likely account for the largest share, and the labor costs associated with instrument installation are also high
Analytical instruments account for a large proportion among the instruments； The costs of software, communication components (networks), CPUs, etc., in control systems are high.
The control system accounts for a relatively high share at some stations
Costs for high-precision instruments, control systems, and software
In large-scale chemical plants, control valves are likely to account for the largest proportion.
The price of communication cables is also high these days
For chemical processing plants, imported components generally account for a large proportion of the project budget, such as equipment and instrumentation systems; this is also the case in the projects we work on.
In medium and large-scale chemical projects, transmitters and control valves account for a large proportion. The system isn’t expensive at all.
What the original poster should be asking about is the engineering budget related to control systems! The investment budget for control systems is quite high in large petrochemical projects, as the cost of certain basic components (such as control valves, transmitters, level gauges, etc.) is significant； In small and medium-sized chemical projects, automatic control systems play a major role. Our company is in the sulfuric acid industry, and in terms of investment in instrumentation, control systems account for one-third of the total investment in instrumentation.

In large petrochemical plants, the DCS and SIS systems for controlling instruments, along with imported transmitters, control valves, isolation valves, and analytical instruments, represent a significant investment
Depending on the different process installations, in some cases the most significant cost components are the important valves, with a single valve costing over 100,000 dollars. A control system – if SIS is not included, it can be acquired for 3 to 4 million. There are also projects for which the technical requirements aren’t high, but there are many points that need to be analyzed, which in turn increases the investment cost. P.S. The total cost of instruments accounts for 20% to 30% of the project cost.
Depending on the different chemical processing units, important valves account for the largest share; in particular, the inlet valves can cost over 100,000 dollars. A control system – these days, it costs 3 to 4 million dollars to develop one. There are also projects for which the technical requirements aren’t high, but there are many points that need to be analyzed, and that too increases the investment costs
