Given that power blackouts occur very infrequently, a TRANSportable GENset emissions reduction system (XGEN) that fixes a larger and more significant problem of reducing emissions from routine periodic testing of gensets, whereas the system may be scheduled to be shared by a multitude of gensets, thereby reducing costs through efficient use of capital expenditures while also increasing the quality of emissions reductions as compared to applying individual exhaust treatments each genset.

A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.

The present invention relates to a toxic gas purification apparatus having a local exhaust function. Here, the purification device is a device for collecting and purifying toxic or harmful gases in places such as a laboratory or a workplace that are easily exposed to various chemical substances. In addition, the purification device includes a local exhaust means for intensively inhaling harmful gas generated at a specific point of interest by the user. Accordingly, the purification device includes an additional function capable of intensively collecting and purifying harmful gases at specific points in addition to the original function of collecting and purifying harmful gases in a wide area.

A modular exhaust subsystem for purifying an exhaust gas feedstream of a compression-ignition internal combustion engine upstream of a base exhaust aftertreatment system includes a selective catalytic reduction (SCR) catalyst, and a first exhaust gas sensor and a first temperature sensor that are arranged to monitor the SCR catalyst. A reductant delivery system is arranged to inject a reductant upstream of the SCR catalyst. A controller is in communication with an engine-out exhaust gas sensor, a second exhaust gas sensor and a second temperature sensor that are arranged to monitor the base exhaust aftertreatment system. The controller controls the reductant delivery system to inject the reductant into the exhaust gas feedstream upstream of the SCR catalyst based upon inputs from the first and second exhaust gas sensors, the engine-out exhaust gas sensor, and the first and second temperature sensors.

Given that power blackouts occur very infrequently, a TRANSportable GENset emissions reduction system (XGEN) that fixes a larger and more significant problem of reducing emissions from routine periodic testing of backup gensets, whereas the system may be scheduled to be shared by a multitude of gensets, thereby reducing costs through efficient use of capital expenditures while also increasing the quality of emissions reductions as compared to applying individual exhaust treatments each backup genset.

Disclosed herein is a system and methods for the reduction of emissions from multiple stationary industrial diesel engines utilized in Hydraulic Fracturing Operations. Mobile Multiple Engine Exhaust Emissions Processing System (MMEEEPS) is a mobile system which comingles exhaust from multiple stationary diesel engines and processes the exhausts through a mobile Diesel Particulate Filter (DPF). In an embodiment, the DPF is mounted on a trailer for mobility. Exhaust stacks from stationary engines connect via flexible insulated piping to overhead trunk line(s), that can be custom assembled to fit the needs of each application. With the assistance of Variable Speed In-Line Blowers (VSIB) the exhausts are captured and lead to single or multiple manifolds, which lead to the MMEEEPS unit. The MMEEEPS unit can be configured to mount to multiple stationary diesel engines in any configuration while utilizing VSIB to aid in capture of the emissions to be processed through a DPF, resulting in a significant reduction in emissions.

A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.

A muffler filter and method for utilizing the muffler filter is provided. The muffler filter includes a housing including an aperture, a cartridge holder, at least one activated filter, an attachable lock associated with the activated filter, and a plurality of clamps. The muffler filter is designed and configured to be securely affixed to a muffler of a vehicle allowing the activated filter to sieve noxious fumes from emissions from the muffler; thus, reducing and/or eliminating noxious fumes distributed in the environment from vehicles.

A maintenance pipe (30) used during maintenance of an exhaust purification device equipped with: a set of an oxidation catalyst (22) and a filter (23) for purifying exhaust gas from an engine (10); an upstream connecting pipe (16A) and a downstream connecting pipe (16B) which are mounted in a demountable way and guide the exhaust gas from the engine (10) to the oxidation catalyst (22); and an exhaust pipe injection device (24) and injectors (12) for increasing a concentration of unburned fuel contained in the exhaust gas. The maintenance pipe includes a flanged steel pipe (31) mounted to be replaceable with the downstream connecting pipe (16B), and a maintenance catalyst (32) that is housed in the flanged steel pipe (31), generates heat caused by oxidizing the unburned fuel contained in the exhaust gas from the engine (10), and heats the exhaust to discharge the exhaust to an exhaust downstream side.
