Jordan Technologies Inc. has developed several patented/patented pending power saving and recovered product measurement devices that can apply to all carbon adsorption / absorption systems. All of these power saving devices have been installed and are operational in the field, showing excellent results as well as allowing for substantial power savings on existing VRU equipment. Listed below, for your review, are three (3) different systems that can be applied to your systems.

The standard VRU can be modified by PLC control to allow for an internal truck counting mechanism for "smart" starting the system. The VRU operation is such that the carbon beds are sized to handle a preset volume of hydrocarbon vapors assuming base inlet hydrocarbon concentrations. Therefore, the VRU can stay in the idle position collecting hydrocarbons while consuming no power until that preset loaded volume has been achieved. At this point, the system will convert to full operation for the required recovery period time then shut back down to reset the process. The truck counting method eliminates the unnecessary power consuming run time when light loading is occurring, thereby reducing power. In addition, we can offer the following three options which will provide additional power savings:

Continuous Emission Start Monitor

The patented Continuous Emission Start Monitor (CESM) in conjunction with the standard truck counting system allows for the VRU to extend the idle and non power consuming time for additional power savings. This is achieved by starting the unit when emissions from the carbon bed that is on line processing hydrocarbons reach a determined set level. At this point, the system will convert to full operation for the required regeneration period time then shut back down to reset the process.

The CESM method of starting the unit by emission measurement eliminates the unnecessary power consuming run time to process vapors therefore saving power more efficiently than the above truck counting method. This is due to the fact that the CESM system takes into account actual vapor concentrations when present from loading and it will only start the VRU when the carbon bed on line is fully loaded whereas the truck counting method only looks at total volumes. In addition, this system continuously monitors vent emission for compliance status.

Continuous Inlet Start Monitor

The (Patent pending) Continuous Inlet Start Monitor (CISM) monitors the vapor inlet flow rate as well as the hydrocarbon inlet concentration from the loading facility to the VRU. Our PLC system converts these values and monitors the total inlet mass of hydrocarbon loaded onto the carbon bed(s) on line. The VRU will stay in the idle position collecting hydrocarbons while consuming no power until a preset loaded mass of hydrocarbons has been achieved. At this point, the system will convert to full operation for a 15 minute cycle then shut down and wait for the second carbon bed on line to be fully loaded then again restart. This system offers the most power efficient VRU available on the market today as well as an estimated product recovery rate. This system also offers additional benefits as follows:

• Alarms when the terminal exceeds the VRU design instantaneous capacity.
• Alarms when the 15 minute, 1 hour, 4 hour and 24 hour design capacity is exceeded.
• Alarms if the inlet design concentration is exceeded.
• Trending of the VRU performance for maintenance and terminal growth. (i.e., terminal has outgrown the VRU's capacity.)

This (Patent pending) system combines both of the above options into one complete system. This alleviates the need for truck counting or signaling from the terminal to start the VRU. This system monitors the inlet mass of hydrocarbons to the VRU bed on line and the unit will not start until the carbon bed that is on line is fully loaded to its capacity of hydrocarbon storage. Once this level has been achieved, the unit will start up, switch the bed that is on line and pull a vacuum on the fully loaded bed for 15 minutes. The unit will then once again shut down and wait for the bed on line to be fully loaded, then repeat the above cycle. In addition, this method of operation allows Jordan to offer in the combined package the following information:

• The most power efficient system available on the market today;
• The ability to measure recovered product;
• The ability to measure unit efficiency;
• The ability to measure unit emissions;
• The ability to reduce wear on all moving components by reducing VRU running time.
• Alarms when the terminal exceeds the VRU design instantaneous capacity.
• Alarms when the 15 minute, 1 hour, 4 hour and 24 hour design capacity is exceeded.
• Alarms if the inlet design concentration is exceeded.
• Trending of the VRU performance for maintenance and terminal growth. (i.e., terminal has outgrown the VRU's capacity.)
