Quick response, transportable, stand-alone system for removing volatile compounds from contaminated fluid streams, and method of use thereof

A system for removal of volatile compounds from oil contaminated water or suspended-solid contaminated water produced as by-product, runoff, or emission from petroleum or chemical manufacturing facilities, the system being a quick response, transportable, stand-alone system relative to the petroleum or chemical manufacturing facilities, the system comprising:

• a) an input inlet for receiving a contaminated water into the system;
• b) a preconditioning subsystem comprising a plurality of baffles and coalescers configured to remove sludge, and filtration and separation media configured to remove particles and debris from the contaminated water to yield a preconditioned water;
• c) a stripping subsystem configured to receive the preconditioned water and configured as a multi-tray gas-liquid contactor comprising a blower and an air or inert gas stripping medium, the blower for targeted and adjustable volumetric flow rate or gas-flow rate, and gas pressure, wherein the multi-tray gas-liquid contactor has an enclosed space with volume no greater than that defined by length dimensions not exceeding about 57 feet, width dimension not exceeding about 9 feet, and a height dimension not exceeding about 12 feet, whereby surface area of gas-liquid contact within the multi-tray contactor is densely packed within the enclosed space of the stripping subsystem, and wherein the air or inert gas stripping medium is pre-cooled by an air intake and cooling subsystem pumped counter-current through the multi-tray contactor, such that vapor liquid mass transfer of the volatile compounds occurs between the preconditioned water and an exhaust gas, concentrating the transferred volatile compounds in the exhaust gas, passing the exhaust gas through a coalescing medium to remove moisture, and yielding a decontaminated water stream;
• d) a compressor configured as a booster blower for accelerating, or at least maintaining, the target volumetric flow rate or gas-flow rate of the exhaust gas as the exhaust gas flows out of the multi-tray contactor and through the remainder of the system;
• e) a condensing subsystem configured to receive the exhaust gas from the stripping subsystem and configured to cool the exhaust gas via an air-cooled or water-cooled, indirect or direct, refrigeration sub-system, wherein the exhaust gas is passed through the condensing subsystem and cooled such that condensable volatile compounds concentrated in the exhaust gas precipitate out from the cooled exhaust gas;
• and
• f) a scrubbing subsystem configured to receive the cooled exhaust gas from the condensing subsystem and configured as a gas-liquid contactor comprising a scrubbing solvent through which the cooled exhaust gas is percolated, wherein the cooled exhaust gas is forced through or into contact with the scrubbing solvent such that volatile compounds remaining in the cooled exhaust gas are concentrated in the scrubbing solvent to yield a decontaminated gas.
