Compressor Cooler for Air Separation Unit | High-Efficiency ASU Intercooler & Aftercooler

Core Customer Pain Points & Targeted Technical

Pain Point 1: Low heat exchange efficiency and bulky equipment, resulting in high site occupancy and low production capacity

Most traditional shell-and-tube coolers matched with air separation compressors adopt ordinary smooth tube structures with single heat transfer components. The heat transfer area is limited, the heat exchange reaction speed is slow, and the overall equipment volume is large. For Middle East and European industrial parks with high plant construction costs and compact layout standards, bulky cooling equipment will occupy valuable installation space; meanwhile, insufficient heat exchange capacity cannot support the stable operation of high-flow air separation systems, restricting the full-load production of ASU units and indirectly reducing enterprise production benefits.

Targeted Solution Principle: Our Compressor Cooler for Air Separation Unit adopts self-developed enhanced heat transfer components and customized finned tube-shell composite structure. This design integrates the high pressure resistance and structural stability of traditional shell-and-tube heat exchangers and the high heat transfer efficiency and compact structure of finned tube heat exchangers. Through surface contact low thermal resistance technology, the heat transfer contact area is effectively expanded, and the thermal resistance of the heat transfer interface is greatly reduced. Test data verifies that its heat exchange efficiency is more than 30% higher than that of traditional ordinary shell-and-tube coolers. The compact integrated structure greatly reduces the overall equipment volume, saving a lot of on-site installation space for industrial users, and fully adapting to the layout requirements of compact and high-efficiency modern air separation production lines.

Pain Point 2: Excessive system pressure loss, leading to long-term high energy consumption and increased operating costs

In the operation process of air separation compressors, the pressure loss of the cooling system is a key factor affecting overall energy consumption. The internal flow channel design of traditional Air Separation Compressor Cooler is unreasonable, with disordered flow field and large flow resistance. The pressure loss of the system is usually above 8-10kPa. Long-term high pressure loss will cause the compressor to consume more power to maintain stable gas flow, resulting in continuous increase in industrial power consumption and greatly improved long-term operating costs for enterprises, which is not in line with the green energy-saving production standards pursued by European and Middle East industrial projects.

Targeted Solution Principle: For the flow field and internal structural defects of traditional cooling equipment, our team has completed multi-round simulation optimization and physical test verification for the internal flow channel of the ASU compressor intercooler aftercooler. The optimized internal structure realizes uniform and smooth fluid flow, effectively reduces turbulent flow and flow resistance inside the equipment. The ultra-low system pressure loss is as low as 3kPa, which minimizes the gas flow loss in the air separation compressor circulation system. This design fundamentally reduces the extra power consumption caused by pipeline and equipment resistance, realizes long-term green energy-saving operation of the unit, and effectively reduces the daily operating energy consumption cost of user enterprises.

Pain Point 3: Poor structural stability and corrosion resistance, causing frequent failures and short service life

Air separation units mostly operate in harsh industrial environments all year round. The cooling equipment needs to cope with alternating high and low temperatures, continuous vibration of compressor operation, and corrosive gas media such as air and CO₂ for a long time. Traditional coolers have single sealing structure, no targeted thermal compensation design, and ordinary surface coating process. They are prone to thermal cracking, sealing failure, medium leakage and structural deformation under long-term temperature difference alternation and vibration impact. In addition, poor corrosion resistance leads to rapid aging of core components, frequent equipment maintenance and replacement, which not only increases after-sales maintenance costs, but also causes production line shutdown losses and affects the stable operation of the entire air separation system.

Targeted Solution Principle: Our Air Separation Unit Cooler adopts multi-dimensional optimized structural design and customized anti-corrosion technology. First, the independent thermal compensation design can effectively offset the structural stress generated by temperature difference alternation and avoid equipment cracking and leakage problems caused by thermal expansion and contraction. The high-standard sealing structure matched with high-quality raw materials ensures excellent impact resistance and deformation resistance, eliminating medium leakage risks. Second, the unique uniform temperature and drag reduction design optimizes the internal stress distribution of the equipment, and the reinforced tube bundle support structure greatly improves the anti-vibration and anti-fatigue performance of the equipment, adapting to long-term continuous vibration operation of the compressor. In terms of anti-corrosion, the customized core group and professional coating process enable the equipment to resist corrosion of various industrial media and harsh environments, greatly extend the service life, and ensure the long-term stable and fault-free operation of the air separation compressor system. In addition, the built-in integrated gas-liquid separation unit realizes one-piece integration of cooling and separation, eliminating the need for additional supporting separation equipment, reducing user equipment investment and installation costs.
