Cryogenic Air Separation Plants ab to 10 000 Nm³/hr
Air Products Air Separation Plants Technology

Worldwide customers requiring large amounts of liquid oxygen, liquid nitrogen or liquid argon trust our Air Products plants years of experience designing, manufacturing and operating cryogenic air separation units . We manufacturing and design the Fractionating column with the best Technologies depend on International standards and our skill workers and engineers. Whether the need is for 50 tpd or 4,000 tpd, Air Products will deliver the most cost and dependable cryogenic solution from conceptual design through our production. We have produced plants worldwide for liquid oxygen, liquid nitrogen and liquid argon ab to 10000 Nm³/hr

Main Air Compressor (MAC) and Booster Air Compressor (BAC)

Atmospheric air is compressed and driven through the system by a series of air compressors. While this image shows electrically-driven compressors, many of them have steam-driven compression. Matching the right compressor design for the specific cycle is critical to optimize energy usage and costs. Air Products engineers (machinery & process design) work directly with compressor manufacturers to assure the best fit. Our machinery operations group is recognized as the best in the industry, experienced with a wide variety of compressors.

Adsorption

The adsorption process removes water, carbon dioxide, nitrous oxide, and hydrocarbons from the feed air stream which is needed for safe operation and high efficiency.. Air Products is on the leading edge of creating the most effective absorbents in the industry, with testing facilities Because site conditions can vary, Air Products uses three different configurations vertical, horizontal and radial flow. We balance reliability, operability and cost to determine which system is optimal. Air Products’ experience assures customers that their absorption process will deliver numerous benefits, including low pressure drop minimizing power, minimized regeneration power, reduced size and cost-effective equipment.

Main Heat Exchanger

The heat exchanger promotes heat transfer between fluids. Air Products offers unique design capabilities to optimize the heat exchanger’s energy efficiency and integration with the process cycle. The ability to customize the equipment for each customer’s comes from a highly experienced engineering sta. and long-term working relationships with leading heat exchanger manufacturers Fractionating column We manufacturing and design the Fractionating column with the best Technologies depend on International standards and our skill workers and engineers. The liquefied air is passed into the bottom of a fractionating column. Just as in the columns used to separate oil fractions, the column is warmer at the bottom than it is at the top. The liquid nitrogen boils at the bottom of the column. Gaseous nitrogen rises to the top, where it is piped off and stored. Liquid oxygen collects at the bottom of the column. The boiling point of argon - the noble gas that forms 0.9% of the air - is close to the boiling point of oxygen.

Argon Distillation

Argon removal systems depend on distillation for purification. Air Products’ Integrated Argon Removal system eliminates the need for a separate column for argon removal. It produces a crude argon stream (90% Ar and 10% O 2 ) out of the main column that results in 3–4% power savings. If pure argon is required, further purification of the crude argon stream occurs in a separate distillation column, or in a proprietary Air Products Argon, which can be added later. Proprietary packing technology allows for a shorter argon column size versus competitive technologies. The smaller column results in production efficiencies and dramatically lower shipping and installation cost

Air Distillation System

Choosing the optimal configuration of distillation column components is not only important in air separation, but vital to minimize capital and operating costs. Air Products was the pioneer in structured packing in 1984.now the accepted industry standard. Structured packing provides a large surface area per volume, which maximizes mass transfer performance and creates lower pressure drop versus conventional distillation trays. Air Products’ proprietary structured packing delivers a higher capacity and lower pressure drop, resulting in lower energy consumption. Combined with our patented liquid and vapor distributors, the Air Products air distillation system offers unequaled distillation performance. Site conditions can vary, so all designs are tested to assure optimal efficiency and reliability before installation

Turbo Expander

Turbo expanders are used to expand air or nitrogen from a higher pressure to a lower pressure, providing refrigeration to produce liquids in the distillation column system. Proper design is critical. Air Products has nearly 50 years of in-house design and manufacturing expertise producing more than 1,300 turbo expanders. This hands-on knowledge assures customers they will receive the highest thermodynamic performance, improved operability, reduced maintenance, and a better integration with the process design

Main Reboiler

The reboiler is the heat integrator of the low pressure and high pressure distillation columns. Air Products offers proprietary technology to enhance the operation and safety of the two industry accepted reboilers used today; down flow and thermosyphon reboilers. The down flow reboiler is preferred as it allows for higher heat transfer coefficients, resulting in less power usage

Backup Systems

On the rare occasion when a gasifier needs to safely shut-down on backup oxygen, a backup system has to start fast and maintain the line pressure within tight limits. Designing these systems and making them work reliably is a real challenge. Air Products’ instantaneous backup system for high pressure oxygen applications is recognized as the best in the world, providing needed confidence to customers.
