A vacuum vapor liquid recovery system employs a strong vacuum vessel that can withstand vacuums without damage. The vacuum vessel may be portable and configured to accept an inflow drain line for receiving waste liquid/vapors from a processing system. Additionally, at least one outflow drain line is attached to the vacuum vessel to which a vacuum truck or other similar recovery equipment can be connected in order to pump out whatever liquids/vapors have been drained into the vacuum vapor liquid recovery system. Additional features can include wheels to assist in moving and positioning the vacuum vapor liquid recovery system, tow bar, transport handles, support legs, sight port, a wash out connector, a vacuum relief, etc.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with a multi-function nozzle assembly including an exhaust nozzle corresponding to a vehicle exhaust port and a fuel nozzle for supplying fuel to a vehicle fuel tank. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. An exhaust conduit may be configured to transport captured exhaust therethrough from the exhaust nozzle to an exhaust holding tank connected to and in fluid communication with the exhaust conduit.

Methods and systems are provided for enabling a vehicle operator to select a desired amount of fuel to add to a fuel tank, and wherein overfilling of the tank is prevented by pressurizing the fuel system with an onboard pump. In one example, the tank may be sealed to induce an automatic shutoff of a refueling dispenser if the fuel level is below the capacity of the tank, and in another example, wherein it is indicated that the tank is full, the fuel system may be pressurized via the pump to induce automatic shutoff of the refueling dispenser and to prevent further overfilling of the tank. In this way, vehicle operators may add desired amounts of fuel to the tank wherein shutoff of the refueling dispenser is automatic, and wherein liquid fuel entering an evaporative emissions control system as a result of overfilling a fuel tank is prevented.

Textured sorbent material sheets provide for enhanced performance in vapor adsorbing applications over conventional sheets, systems, canisters and other emissions control equipment. The textured sorbent material sheets can be formed as part of a small, lightweight system, canister, or can be integrated into a fuel tank.

Embodiments of systems and methods for transporting liquefied gas and carbon dioxide (CO2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with an outer surface, an outer compartment within the outer shell configured to store liquefied gas, a bladder positioned within the outer compartment configured to store CO2, and insulation positioned between the outer shell and the outer compartment to provide temperature regulation for the liquefied gas when positioned in the outer compartment and CO2 in the bladder.
