The turboexpander compressor unit is the key equipment of the cracking unit of the ethylene plant. Its stable operation is related to the normal production and energy consumption of the entire cracking unit. The design of the system fully considers the safety of the unit and the requirements for long-term stable operation. In order to ensure the reliability of the system, the lower-level measurement and control instruments are selected from the current international advanced level instruments, and achieve high-level decentralized control through the bus communication with the upper computer. Even if the upper computer fails or shuts down, the whole unit can still be in the lower position meter. The normal operation under the control avoids the influence of the upper computer/dead machine 0 in the DCS on the system and improves the redundancy of the system. The modules in the system are highly dispersed, using universal instruments, universal buses and protocols, which not only improve maintainability, but also are easy to expand and upgrade, and enhance the openness of the system.
Environmental noise Small new equipment has high quality, good performance, low vibration and low noise. The old air compressor not only has a noise higher than 100dB, but also has a large vibration. The noise of the new air compressor after the transformation is less than 85dB, and the operation is stable. The central centralized control system has reached world-class levels. The turboexpander compressor unit is essential for the cracker, which not only increases production efficiency but also saves energy. According to the processing result, the parameters of the lower level meter are adjusted and sent to the database together with the real-time data; the data analysis module can provide an effective means for fault diagnosis and prediction of the expansion compressor unit, and the successful application of the control system in the ethylene cracking device realizes Real-time monitoring of the operating parameters of the turboexpander group, historical data storage, unit operating state analysis and fault diagnosis and prediction. The whole system has high reliability, good safety, openness and easy maintenance. It completely replaces the imported system and has wide promotion value.
Ecohydraulic forward-out baler has been used by many customers to press non-ferrous metals, such as used beverage cans (UBC), scrap aluminum chips, scrap copper chips etc. So it is also called tin Cans Baler, aluminum chips baler, metal chips baler, aluminum powder baler etc. Forward-out aluminum Balers are widely used by recycling centers due to their efficient and proficient working mechanism. The larger aluminum can baler models can be customized to compress metal leftover, steel shavings and steel scraps. Furthermore, the optional manual and automatic control systems of the cans baler enable the automation of machine and allow the manual use as well.
