1 ECS Membrane Processor Overview 1.1 ECS Membrane Processor Theory of Operation VST EVR Total Balance System Solution • The VST ECS membrane Processor does not interact directly with the other balance system hardware. It is in place to monitor and control the pressure in the UST to within limits specified by CARB. Under conditions where the GDF is operational and the balance system hardware is functioning normally, the inherent ORVR compatibility of the balance system (when using VST’s ENVIRO‐LOC nozzle) will produce a predominately negative gauge pressure in the ullage space of the UST. Under these conditions the ECS membrane Processor will typically not need to operate. During periods of less activity, the GDF being shut down overnight, winter fuels being present, or other conditions that promote the pressurization of the ullage space, the ECS membrane Processor will operate as needed to control the pressure in the ullage space to an accepted level. The ECS membrane Processor will turn on at an ullage pressure of +0.20 inches of water and turn it off at a pressure of –0.20 inches of water. Currently, the ECS membrane Processor unit is monitored and controlled through the ISD system. • The ECS membrane Processor uses a type of membrane technology to enable it to selectively separate the components in the ullage vapor mixture. Through a somewhat complex transport means, certain molecules will selectively travel in a stream from one side of the membrane to the other. This stream is referred to as the permeate stream. In this case, the predominate molecules transported across the membrane will be the primary constituents of air, which are oxygen, nitrogen, and water vapor. A small amount of the hydrocarbons present in the ullage mixture will also migrate across the membrane. Typically, the permeate will contain less than 3.0% hydrocarbons. The result of this activity includes, fresh air vented to atmosphere, saturated hydrocarbon vapors returned to the UST, and UST pressurization controlled to an acceptable level. • The process of separation by the membrane is made possible by using two pumps, one low‐pressure pump which circulates the ullage vapor mixture along one side of the membrane, and one high‐vacuum pump, which creates the pressure differential needed to cause the permeate transport across the membrane. These are the only moving parts in the system. A self‐regulating heating coil is incorporated around the membrane housing to keep the membrane free from condensate.
