A system for processing objects to be cleaned that includes a processing vessel, and a storage vessel that includes an upper section for storing clean liquid and a lower section for storing dirty liquid. The upper section and lower section are in flow communication.

A road vehicle having: a frame; four wheels, which are mounted on the frame in a rotary manner; a body, which covers the frame; a compressor, which produces a compressed gas; and at least one tank, which receives the compressed gas from the compressor and has a containing chamber, which is delimited by a wall. The wall of the tank includes: an inner panel, which directly delimits the containing chamber and is in contact with the compressed gas; and an outer panel, which completely surrounds the inner panel and is arranged parallel to the inner panel and at a constant distance from the inner panel.

A multi-stage gas compression system useful at the production site and at central collection points, having an energy efficient and effective intercooler system. The system includes a reciprocating compressor having a plurality of compressor valves and cylinders configured in series to provide staged compression to the natural gas. Coupled with the compressor are an inlet port for receiving natural gas to be compressed, and an outlet port for delivering compressed fluid from the compressor to a discharge line, to the transmission pipeline or storage. Facilitating transmission and intercooling of the natural gas between cylinders are a plurality of pipes, each pipe in close proximity with an intercooler. The rate of cooling of the intercooler is determined by a control system coupled therewith, including a temperature sensor positioned within pipe proximal to the intercooler, and means to compare the temperature measured by the temperature sensor and an optimal temperature or temperature range, and determine appropriate levels of cooling provided by the intercooler.

Systems and methods are disclosed for transporting products with an airplane by controlling temperature in a payload bay using cryogenic coolant and a heat exchanger to cool the payload bay and heat from a heater; recycling exhaust from the heat exchanger to power a Stirling engine; charging a storage device with power from the Stirling engine; housing the payload bay as part of a modular, stackable module in an aircraft bay for transportation; and venting exhaust gas to an exterior of the airplane.

In processes and systems utilizing a compressor to fill a vessel with gas, for example, in the filling of the fuel tank of a vehicle that operates on compressed natural gas (CNG), a number of advantages are realized by establishing independent control over the flow rate of gas discharged from the compressor, such as on the basis of the compressor discharge pressure, utilizing feedback from one or more gas pressure sensors. In representative embodiments, a detected or actual measured compressor discharge pressure can serve as a process variable, in a feedback control loop for regulating the output of the compressor.

The present invention is a hydrogen cooling apparatus comprising: a air-cooled condenser disposed on a part of a first coolant passage so as to enable cooling of a first coolant by driving an air-cooling fan; a first heat exchanger enabling cooling of a second coolant by the first coolant, between another part of the first coolant passage and a part of a second coolant passage; and a second heat exchanger enabling cooling of hydrogen by the second coolant, between another part of the second coolant passage and a part of a hydrogen passage. A driving rotational speed of the air-cooling fan is inverter controlled in such a manner that a pressure of the first coolant from the air-cooled condenser to the first heat exchanger is maintained between 1.5 MPa and 1.7 MPa.

Methods and systems for recompression are disclosed. In certain embodiments, a method may include receiving a fluid from a first conduit or container at a first pressure. The method may include using a multi-stage compressor which is non-removably mounted to a trailer to compress the fluid through one or more compression stages. The method may include cooling the fluid after each stage of compression, scrubbing liquid from the fluid before each stage of compression, and discharging the fluid to a second conduit or container at a second pressure.

Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG).
