Customers who require large, or "tonnage" volumes of oxygen and/or nitrogen in a continuous fashion can obtain them from BIG dedicated plant or pipeline. The products will commonly be produced in a cryogenic air separation plant which operates by compressing air and cooling to cryogenic temperatures under which conditions the air liquefies and can be separated by distillation.

BIG has provided tonnage Nitrogen and Oxygen supply solutions to our customers who are leader in refining and pretrochemical in Mab Ta Phut as well as gigantic Steel Mills in Chonburi

Plants supplying up to 4000 t/d gaseous oxygen are available to meet the needs of the metals, glass, refining and petrochemical industries. These plants co-produce nitrogen and frequently are constructed to produce liquid oxygen and nitrogen as local back-up or for merchant export. A similar flexibility in size is available in nitrogen-only plants which find application in metals, electronics, refining, chemicals, enhanced oil recovery and natural gas dilution.

Outsourcing can lower the cost of hydrogen, carbon monoxide or syngas ("HyCO") to the refining or petrochemical industries. It is a core product to an industrial gas company strategically focused on HyCO. Our skills and expertise are geared towards producing HyCO products in the most cost effective and reliable manner. Our affiliates own and operate 35 steam reformers and partial oxidation units around the world, located in areas of high refinery and petrochemical activity such as: Rotterdam, The Netherlands; Texas and Louisiana, US Gulf coast; Los Angeles Basin, California.

Utilizing this continuous operating experience, the industrial gas supplier brings advantages in HyCO supply not normally available to the typical refiner or chemicals producer. Feedback and bench-marking from its own HyCO plants allows continuous improvements to be made both in initial design and in on-going optimisation, offering significant cost savings. Further cost reductions are possible by linking HyCO consumers together through a pipeline supply network with multiple plant capability.
With large capital investment expected to be required - especially in refining in the near to mid-term and with refining margins not expected to be supportive of such investment - out-sourced HyCO supply offers an effective way to minimise costs. Perhaps more significantly in today's climate, it releases capital for other investment opportunities aimed at improving the refinery margin.
