In current chemical manufacturing plants, the decision to generate gases internally or resort to conventional gas supplies in liquid form extends beyond logistics and into an integral part of determining future success and viability. Modern chemical production requires oxygen and nitrogen in highly pure form to be used in processes such as reaction, purging, and inerting operations. The problem lies in the unpredictability and fluctuation in the cost of liquid gases. At DINAK, a professional manufacturer with over 20 years of experience in the air separation industry, we specialize in developing and optimizing gas processing, separation, and liquefaction technologies. Our advanced Gaseous ASU solutions are designed to liberate chemical manufacturers from the constraints of third-party suppliers, offering a more stable, safer, and cost-effective alternative to traditional liquid gas procurement.
Economics of On-Site Gas Production
Lowering Long-Term Gas Procurement Costs
For many chemical facilities, purchasing liquid oxygen or nitrogen involves paying a significant premium for the supplier’s liquefaction energy, specialized transportation, and profit margins. When you rely on a liquid nitrogen supply, you are continuously exposed to variable supply and logistics. We have found that by switching to a Gaseous ASU, plants can eliminate these external overheads. Our systems utilize a sophisticated cryogenic distillation method to separate air into its components on-site, significantly reducing the unit cost of gas. Because our Gaseous ASU is optimized for energy efficiency, the electricity consumed by the air compressor is the primary variable cost, providing much more predictable operational budgeting than market-linked liquid gas contracts.
Accelerating On-Site Gas Plant ROI
Investing in on-site infrastructure is often viewed with caution due to initial capital expenditure. However, the on-site gas plant ROI for a DINAK system is remarkably compelling. We design our Gaseous ASU units with an ultra-low pressure process that can reduce the operating pressure of the raw material air compressor significantly, which directly lowers power consumption. By reducing these core energy requirements, the savings generated from purchasing liquid products allow the equipment to pay for itself in a relatively short timeframe. Furthermore, we provide customized solutions that tailor the gas output and purity to your exact process needs, ensuring you aren't paying for "over-specified" gas purity that your specific chemical reaction doesn't require.
Reliability in Chemical Process Integration
Avoiding Volatile Liquid Supply Logistics
Relying on a fleet of trucks to deliver liquid products to your Cryogenic Liquid Vacuum Storage Tank introduces numerous failure points. Traffic delays, driver shortages, or extreme weather can disrupt gas supply to critical chemical processes or chemical reaction feed lines, leading to catastrophic downtime. In contrast, a Gaseous ASU draws its raw material—ambient air—directly from the environment. This eliminates dependence on external transportation logistics. While some plants maintain Seamless steel gas cylinders or Welded Insulated Cylinders as emergency backups, these are temporary fixes. A DINAK on-site plant ensures that your industrial gases are as available as the electricity and air that power them.
Achieving Continuous Industrial Operational Stability
In chemical processing, production may be round-the-clock and process stability becomes very important. The Gaseous ASU design allows the unit to operate continuously without any disruptions. Its automated system ensures that despite fluctuations in demand, stable outputs can still be achieved. The inclusion of the advanced Instrumentation and Control System (DCS/PLC) ensures that the operation of the unit will always be within its most optimal conditions. This is very important especially since the process of chemical manufacture requires precise control.
Safety and Efficiency of Gaseous ASU
Advantages of DINAK Internal Compression
The primary technical challenge involved in supplying gas chemically is that of delivering the gases under high pressure. At DINAK, we utilize an advanced Internal compression process. In this setup, the product is pressurized in its liquid state using a high-efficiency liquid pump before being vaporized in the main heat exchanger. This internal pressure technology can meet high-pressure requirements without the need for large, external gaseous compressors, significantly enhancing the safety profile of your facility.
Energy Savings with Ultra-Low Pressure
Energy use stands as the biggest variable expense in industrial gas making. Our Gaseous ASU solutions incorporate an innovative ultra-low pressure process that minimizes the core energy consumption of the equipment. By optimizing the heat exchange and distillation through high-efficiency packed towers, we reduce the resistance within the Fractionating Column System, improving overall energy efficiency of the ASU system.
Deployment and Lifecycle Maintenance
Modular Air Separation Unit Installation
We understand that construction timelines in chemical plants are tight. To address this, DINAK focuses on a modular air separation unit design. Our main equipment is often skid-mounted, which means it is pre-assembled and tested at our manufacturing base before being shipped. This modularity reduces the footprint required on-site and significantly shortens the installation and commissioning period compared to traditional "stick-built" plants. It enables faster installation and commissioning, getting your on-site gas supply online with minimal disruption to existing infrastructure.
Professional Support and Remote Diagnostics
The life span of any industrial oxygen generator is directly related to its maintenance and support. We offer you a complete Maintenance Agreement that involves regular check-ups and preventive maintenance in order to increase the lifetime of your equipment. In addition to that, we offer you Remote monitoring & diagnostics that allow our engineers to analyze the condition of your equipment remotely. This way we can detect possible issues early enough and fix them without sending our specialist to your place.
Conclusion
The decision to transition from external liquid gas supply to an on-site Gaseous ASU represents a significant milestone in a chemical plant's journey toward operational excellence. While liquid gas procurement may seem convenient in the short term, the cumulative benefits of on-site generation—ranging from drastically reduced unit costs to enhanced safety and supply stability—make it the superior choice for the future of chemical manufacturing. DINAK remains dedicated to providing the industry with the most advanced, reliable, and energy-efficient cryogenic technology. By leveraging our modular designs and high-pressure Internal compression process, chemical plants can secure a stable and continuous industrial gas supply that fuels growth and sustainability for decades. Investing in a DINAK air separation system is not merely an equipment purchase; it is a strategic investment in the long-term competitive edge of your facility.

FAQ
Q: Is it cheaper to produce gas on-site than to buy liquid?
A: Yes, for most medium-to-large scale chemical operations, a Gaseous ASU significantly reduces the cost per unit of gas by eliminating high transportation fees, supplier markups, and the energy costs associated with the liquefaction and vaporization of external supplies. Our Gaseous ASU uses an ultra-low pressure process to further minimize electricity consumption, leading to a much lower total cost of ownership.
Q: How long does it take to see a return on investment for an ASU?
A: While the payback period depends on your specific gas consumption and local electricity rates, many chemical plants achieve favorable ROI after several years of continuous operation, depending on gas consumption and electricity pricing. Our modular air separation unit design also lowers initial infrastructure and installation costs, which helps accelerate the on-site gas plant ROI.
Q: Can a Gaseous ASU be customized for different purities?
A: Yes. We understand that every project is unique, and we support comprehensive customization in terms of gas output, purity, and pressure.
