Precise temperature control + whole plant design: AODE helps the efficient and stable production of photoresist and semiconductor packaging materials

The whole plant industrial temperature control solution     

Company A is an electronic chemical enterprise focusing on the production of intermediates and electronic grade epoxy resins. As A key link in the semiconductor industry chain, Company A puts forward extremely high requirements for temperature control in the production process to ensure product quality and production efficiency.

Project pain point

• Lack of experience: The engineering team of Company A previously mainly used laboratory-level temperature control equipment and lacked experience in the design and implementation of large-scale production temperature control

• The whole plant design problem: Company A has not conducted a comprehensive design of the whole plant temperature control system before, resulting in low system integration and poor operation efficiency

• Insufficient temperature control accuracy: the traditional equipment will return temperature phenomenon at low temperatures (such as -15℃), affecting the stability of production

• Low efficiency: traditional temperature control equipment has high energy consumption, and the product pass rate is difficult to reach the standard, resulting in a large amount of raw material waste

• High temperature demand: Company A needs high temperature support in the production process, but there is no steam supply on site, which needs to rely on high-power electric heating boilers, and such equipment requires special equipment manufacturing qualifications, which many factories cannot meet

Solution

AODE provides A comprehensive temperature control solution for Company A, covering heating main unit, piping system, secondary medium temperature control system, expansion system, control system.

Core advantage of AODE series temperature control system

Closed constant pressure design

1. The fully closed cycle design effectively reduces the risk of oxidation, moisture absorption or volatilization of the thermal conductivity medium

2. Especially when the heat conducting medium is organic compounds such as glacial refrigerant and glycol, the service life of the heat conducting medium can be effectively improved and the frequent replacement of the heat conducting medium can be avoided

3. The selection of heat transfer media can achieve a large range of (-30℃ ~ 280℃) temperature adjustment

Intelligent energy-saving solution

1. In real-time, dynamic and accurate calculation of energy demand, a dual-variable (flow + temperature) integrated control mode is optimized to achieve maximum energy saving while ensuring energy point control accuracy

2. Achieve repeatability of system operation and improve the stability of product quality

Formulation management

1. It supports online programming of the control system and self-establishing process curves. You can adjust the running curves according to your own production process and automatically generate and save formulas

2. The operating curve can be recorded in real time to help optimize the process

3. The unattended automatic completion of the process control process

Realize the confidentiality of process technology

Optimization of control technology

1. A feedforward PID temperature control algorithm based on industrial fuzzy control technology enables temperature control accuracy to rise to a higher level

2. The complexity and nonlinearity of energy point control process can be used to solve the time-delay problem of traditional temperature control

3. AODE have been engaged in industrial temperature control for 21 years, and have experience in system process design, temperature control debugging and temperature control conditions calculation. The core control model and method are derived from the advanced and mature control technology and the design and debugging method of the European cooperation company, which can realize the stable operation of the system

Customized solutions

Based on the customer's specific process, the requirements for control accuracy and the on-site use of environmental requirements, combined with the design, commissioning experience, to provide customers with different temperature control solutions.

At present, at the customer site, from the basic cryogenic refrigeration unit, heating host, to the TCU temperature control unit, AODE output the temperature control design of the whole plant, through the dynamic control of material temperature can reach ±0.5℃ (some can reach 0.3℃) accurate control, greatly improving the production efficiency and product batch stability.

The on-site electric heating boiler (AODE has the qualification) ensures the stable operation of the whole plant, and the efficiency is relatively high, which is recognized by customers.

In the field of core components of photoresist and key raw materials of semiconductor liquid packaging materials, AODE's whole-plant design capabilities, precise temperature control technology and energy-saving design not only meet the current needs of Company A, but also successfully solve the temperature control problems encountered in the production process, significantly improve the production efficiency and product qualification rate, and provide a reliable guarantee for its future expansion.
