ON-SITE OXYGEN SOLUTIONS
PCI Gases, located in Riverside, USA, specializes in air separation equipment for producing nitrogen or oxygen, catering to sectors such as Medical, Industrial, Oil & Gas, and Military. Their primary product line, DOCS, is utilized for both industrial and medical-grade oxygen production.
PCI employs Vacuum Swing Adsorption (VSA) technology, which is more reliable and energy-efficient than traditional Pressure Swing Adsorption (PSA) systems. VSA technology uses fewer components, resulting in higher reliability and 50% less power consumption, significantly reducing operating costs. The Load Following Smart Control System adjusts the VSA blower motor speed based on demand, saving energy during reduced flow periods. Additionally, PCI's systems offer remote monitoring capabilities via the internet for performance tracking and troubleshooting. A notable feature is the 10-year warranty on VSA adsorber beds, a unique offering in the industry.
The DOCS product line includes models such as DOCS 80, 200, 500, 1500, and 5000, each designed for different capacity needs.
VSA systems are significantly more energy-efficient, consuming 0.65 kWh/m3 compared to PSA systems' 1.5 kWh/m3. They have fewer components and process valves, reducing maintenance needs and increasing reliability. VSA systems are oil-free and do not require dryers, minimizing environmental impact and operational costs.
The city faced odor issues due to high hydrogen sulfide levels. A novel oxygen injection system using VSA technology was implemented, significantly reducing odor and infrastructure corrosion. The study highlighted VSA's lower energy consumption and maintenance needs compared to PSA, making it a more cost-effective solution for the city.
An energy study at Laguna Beach demonstrated significant energy savings with VSA systems, showing an average power demand of 9 kW compared to 20.3 kW for PSA systems, resulting in annual energy savings of nearly 90,000 kWh. The lifecycle cost analysis indicated potential savings of approximately $265,000 over ten years, with a payback period of 22 months.
PCI Gases provides Deployable Oxygen Concentration Systems (DOCS) ranging from 80 to 5000 liters per minute, designed for on-site oxygen generation, eliminating the need for resupply logistics. The DOCS systems operate at an oxygen purity of 93% ± 3% and output pressures ranging from 10 to 100 psig, functioning in temperatures from 0°F to 120°F. They feature remote monitoring, mass flow control, and automatic sleep mode for low-demand situations.
Switching to VSA technology reduces energy consumption and decreases greenhouse gas emissions. Over ten years, a VSA system can save 870,000 kWh of energy and prevent the emission of approximately 3,500 metric tons of greenhouse gases, offering substantial environmental and economic benefits.
- DOCS 5000: Produces 5000 lpm with 93% purity, operates at 6-10 psig, and requires a power supply of 380/460/575 VAC, 50/60 Hz, 3-Phase. Average power consumption ranges from 135-170 kW.
- DOCS 1500 Booster: Works with the DOCS 1500 oxygen generator, providing output pressures up to 100 psig, operating at 380/460/575 VAC, 50/60 Hz, 3-Phase, with power consumption between 20-28 kW.
Operating temperature for both models ranges from 0°F to 120°F. Performance parameters are based on standard conditions (59°F, 14.7 psia, 0% RH).
- Remote monitoring and diagnostics suite available.
- 4-20 mA communication to external controllers.
- Automatic sleep mode for low-demand situations.
- Platinum 3 plus 10 Warranty.
- Modularized components for rapid, low-cost installation.
- Average scheduled maintenance cost is $200-$300 per month.
- Average operating cost at 55 psig is $0.10-$0.14 per 100 scf.

advancing air separation technology To produce oxygen from air, PCI uses a proprietary Vacuum Swing Adsorption (VSA) process that eliminates many of the design problems associated with traditional Pressure Swing Adsorption (PSA) systems. Our innovative VSA system eliminates the need for process valves, feed air compressors, and associated dryers and feed air filtering systems. PCI's robust VSA process extracts maximum sieve and power efficiencies = low cost (both CapX and OpX) high purity oxygen generation.

advancing air separation technology ! has been running for approximately 5 minutes or more. enabled by default for all industrial units. PCI’s load following “smart control system” PCI's Load Following feature saves energy by slowing down the VSA blower motor during periods of reduced flow. DOCS machines have a process tank which helps smooth out the vacuum swing adsorption process and provides uninterrupted gas flow. During the VSA process, the pressure in the process tank cycles between a maximum value and a minimum value. During periods of high flow demand, the minimum process tank pressure...

VSA ADSORBER VESSEL GUARANTEE DOCS PLATFORM VSA ADSORBER BED GUARANTEE The Vacuum Swing Adsorption (VSA) process used in our Deployable Oxygen Concentrator Systems (DOCS) is based on a totally reversible cycle. Different than systems using Pressure Swing Adsorption (PSA) process technology, the water vapor in the air does not condense out during our process cycle. As a result, the molecular sieve does not degrade over time. In addition, our molecular sieve beds have a unique design that mechanically holds the sieve media in place, thus eliminating any material attrition. Therefore, under normal...

Energy Measurements and Analysis As part of PCI’s energy study for Laguna Beach, a power meter was attached to the power supply for the compressor on the PSA system located at one of the city’s lift stations. Figure 2 shows the power consumption data recorded and indicates the average power demand of 19.2 kW. Another 1.1 kW of demand that was not measured on this power line can be attributed to the dryer and controls circuit, for a total average power demand for this PSA of 20.3 kW. Conversely, the competing VSA system installed at the second lift station has a total average power demand of 9...
