A system for reclaiming fuel from a vehicle fleet is comprised of a trailer capable of defueling multiple vehicles simultaneously that operates in conjunction with a remote computing device. The remote computing device communicates bi-directionally with an on-board computing device located in a combustion engine vehicle, where the on-board computing device is directed by the remote computing device to cause the vehicle's fuel pump to operate without starting the vehicle's engine. The remote computing device also queries for and receives data about the vehicle from the on-board computing device, such as the Vehicle Identification Number, diagnostic information about the vehicle, and/or data about how the vehicle is being driven and transmits such data to at least one second computing device in communication with the remote computing device.

An apparatus and method are provided for offloading cargo from a tank trailer, which has at least interior compartments, to one or more discharge points. The apparatus includes two or more T-connectors each of which is connected, via a valve, to an outlet of a respective one of the interior compartments of the tank trailer. Each T-connector has an axis defined by a pair of opposing arms and, contrary to conventional apparatus and methods, the T-connectors are positioned with their axes oriented perpendicularly or obliquely relative to the length of the tank trailer. Additionally, for each T-connector, a discharge conduit is connected to one of the opposing arms so that all of the discharge conduits extend from the same side of the tank trailer, perpendicularly or obliquely relative to the length of the tank trailer. A blower conduit is also connected to each T-connector, to the other of the pair of opposing arms, and extend from the other side the tank trailer, opposite the discharge conduits. The blower conduits are also connected to at least one blower which provides air flow and pressure. The method involves providing power to the blower(s), and opening the valves to cause the cargo to flow from each of the interior compartments and form multiple flow streams which flow concurrently, along multiple flow paths, to the one or more discharge points. This apparatus and method reduce the time necessary to accomplish offloading the cargo, among other advantages.

A simple and lightweight solution to the storage and delivery of dry flowable materials that is cost-effective, can be standardized to facilitate transportation and isolates the materials from exposure to air, insects and other contaminants. An apparatus includes a vessel and a delivery assembly, having a rotary feeder that upon gravity discharge of the dry flowable material moves such material to a desired location.

Systems and methods are disclosed that may include providing a wellhead gas burner to burn wellhead gas produced from a wellhead to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may include a pressure regulator and an expansion chamber that permit the wellhead gas burner to continuously operate and accommodate wellhead gas pressure fluctuations. The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional propane/diesel gas burner system configured as a supplemental heat source. The wellhead gas burner may also be mounted to a mobile superheater truck.

A loading arm that transfers flowing bulk material from a storage vessel and into a transport tank through a top hatch of the transport tank that is carried on a truck or rail car for transport includes an articulating arm having a plurality of connected hollow pipes. A hatch plate connected to the discharge of the aim and defines a top member, a bottom member and an outer edge connecting the top and bottom members. At least one of the bottom member and the outer edge of the hatch plate defines a resiliently flexible section configured to deform upon engaging with the top hatch of the transport tank.

Fluid delivery vehicles, such as water trucks, and fluid receiving units for use at well sites, storage facilities, treatment facilities, rail and barge terminals are disclosed. The fluid delivery vehicle has primary fluid discharge assembly downwardly extending from a tank on the fluid delivery vehicle for discharge of fluid into a fluid containment unit configured to contain a larger volume of fluid than the tank arranged below the fluid delivery vehicle.

A pneumatic tank trailer is described. A front end cover is positioned over a front portion of the pneumatic tank trailer. The front end cover partially covers and attaches to a front end cone of the tank. The front end cover also covers plumbing and fittings for a pressurization system of the pneumatic tank trailer. The front end cover improves the aerodynamics of the trailer by providing a smooth surface with a large radius transition from the front cover to the tank.

This invention is directed toward a self-contained heated portable vacuum slurry box which is manufactured from steel rated for cold temperatures. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay containing a power unit, and a tailgate, a The invention herein utilizes a selection of steel that allows for a vacuum slurry box to function in the cold environmental conditions.

A hydraulic system includes a hydraulic circuit, a heater, a temperature sensor, and a controller. The hydraulic circuit includes a reservoir configured to store hydraulic fluid, a pump coupled to the reservoir, a driver positioned to drive the pump to pump the hydraulic fluid from the reservoir and throughout the hydraulic circuit, and an actuator positioned to selectively receive the hydraulic fluid from the pump to operate a controllable machine component. The driver is independent of a prime mover of the machine. The heater is positioned to facilitate selectively heating the hydraulic fluid. The temperature sensor is positioned to acquire temperature data indicative of a temperature of the hydraulic fluid. The controller is configured to monitor the temperature of the hydraulic fluid and selectively activate at least one of the heater or the pump to thermally regulate the hydraulic fluid to maintain the hydraulic fluid within a target temperature range.

A collection tank for a mobile vacuum excavator includes a front with a closed end, a rear with an open end, a door configured to be closed over the open end, and a linkage assembly having a first end attached to the door and a second end attached to the body. A first pivotal movement drives the first end and second end away from each other, and a second pivotal movement moves the first end and the second end toward each other. An actuator is attached to the first arm and to the second arm so that actuation of the actuator in a first direction drives the first pivotal movement and actuation of the actuator in a second direction drives the second arm the second pivotal movement.
