A system, process and method for remediating contaminated soil and solvent recovery. A solvent mixture including a polar and a non-polar solvent is mixed with contaminated soil in mixing vessels, allowing the solvent mixture to extract contaminates from the soil. The solvent mixture is separated from the soil using bicanting units to form a solvent stream and a soil stream. The soil stream goes through air sparging in a dryer to remove residual solvent vapor. Water and/or micro-fines are extracted from the solvent stream using a centrifuge. The solvent stream undergoes distillation in a distillation unit to remove the containments from the solvent stream, while recovering separately the solvent mixture and a product. The recovered solvent mixture can be recycled back to the mixing vessels. The contaminates can be BTEX or F1-F4 hydrocarbons, and the product can be oil or other hydrocarbons. The system can be mobile.

STAXLINK™ is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.

A drying device for removal of water at least from a liquid is provided with a connection head to be connected to a housing wall of a device for receiving the liquid. Dryer modules each containing a drying agent are provided. The dryer modules are connected by an articulated connection to each other, respectively. The dryer modules include a first dryer module and a last dryer module, wherein the last dryer module has at least two rotatory degrees of freedom relative to the first dryer module and/or relative to the connection head. Drying systems are provided with such a drying device to remove water from a liquid.

Settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices include a stack of cones with a small opening oriented upwardly or downwardly. The cones have an interior surface that is convex. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste-water treatment.

A waste treatment device may include a solid-liquid separator which is configured to receive and separate waste into solids and liquid. The waste treatment device may further include a solids treatment arrangement which is configured to receive the solids from the solid-liquid separator, wherein the solids treatment arrangement comprises a disinfection unit having a heating mechanism configured to heat, without burning, the solids so as to disinfect the solids to convert the solids into pathogen-free-treated-solids. The waste treatment device may further include a liquid treatment arrangement which is configured to receive the liquid from the solid-liquid separator and to treat the liquid so as to convert the liquid into pathogen-free-effluent. The solid-liquid separator may include a curved-funnel-shaped inner separator surface and a frustoconically-shaped inner liquid guide surface whereby the respective narrower ends are directed towards each other.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to a dispersing device mounted over or adjacent to a shaker such as a linear shaker. The shaker receives and processes the output of the dispersing device and dewaters solids. The underflow of the shaker is recirculated through the tank.

Apparatuses and methods for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits are disclosed. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly.

A mobile oil filtration system includes a mobile oil reservoir having a plurality of wheels; a housing secured to the mobile oil reservoir; an input conduit secured to the housing; a pump in fluid communication with the input conduit; a spring-loaded filter downstream from and in fluid communication with the pump; a bag filter downstream from and in fluid communication with the spring-loaded filter; and an output conduit secured to the housing and in fluid communication with the bag filter.

A transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component and a primarily liquid component. The separation apparatus includes a first separation area disposed on the separation apparatus for receiving spent materials and beginning separation of the spent materials. The separation apparatus designed to be connected to a vehicle to be pulled on commercial roadways. The separation apparatus also includes a second separation area in fluid communication with the first separation area for further separation of the spent materials. The separation apparatus can further include an auger in fluid communication with the first separation area to remove the primarily solid component from the separation apparatus. A method of introducing and separating the spent materials via the separation apparatus.
