Abstract: A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time.

Abstract: Multiple fluid nozzles are mounted in a machine tool such that the cutting tool in the spindle is targeted with liquid or gas cutting fluid from multiple directions, providing better coverage and thereby more effectiveness. This provides more efficient and safer use of a machine tool by automating the aiming of fluids at a desired location. Multiple nozzles at respective multiple physical locations are preferably controlled by a single control unit, so they can be synchronized to maintain a common target point on a cutting tool, even if the nozzles are located asymmetrically or non-uniformly with respect to the spindle axis or target point. Preferably, modular nozzle assemblies can be configured for flexibility in mounting on the machine tool.

Abstract: A process is provided for removing polymeric fouling on process equipment surfaces to restore the efficiency of such equipment. This is accomplished by contacting the fouled equipment with a solvent comprising at least one non-aromatic hydrocarbon compound, or a mixture of one or more non-aromatic organic compounds and one or more aromatic hydrocarbon compounds, for a period of time sufficient to remove the polymeric fouling.

Abstract: A process is described for removing olefinic polymer mass buildup fouling process equipment to restore the efficiency of such equipment. This is accomplished by circulating through the equipment in contact with the polymer an aromatic hydrocarbon solvent having a high boiling point and low vapor pressure for a period of time sufficient to remove the polymer. The solvent is recovered for reuse by a flash separation from the removed olefinic polymer mass.

Abstract: A method of controlling the emission of volatile organic compound vapors from storage vessels via pressure swing absorption utilizing a single adsorber vessel is disclosed.

Abstract: A method and device for installing gasket members between two adjacent flat plate structures including removably attaching a gasket member on each side of a frame member to form a frame member and gasket member assembly, interposing the frame member and gasket member assembly between at least two cell frame members disposed adjacent to each other, and contacting the flat plate structures with the frame member and gasket member assembly such that the gasket members adhere diametrically opposed to each other on the flat plate structures. The frame member includes a rib portion around the outer periphery of the frame member, the rib portion forming a pair of shoulders opposite each other and facing away from each other and adapted for receiving a pair of gasket members such that the gasket members contact the rib portion and protrude a predetermined distance beyond the shoulder members.

Abstract: An electrolysis flat plate cell frame separating device for changing out one or more cells, gaskets and/or membranes from a stack in a flat plate membrane cell electrolyzer without having to shift other cells one at a time and a method of use.

Abstract: The present invention is directed to a process and apparatus for controlling the pressure load on gaskets of an electrolysis cell by comparing the internal cell pressure to the pressure of the hydraulic fluid to the cell compressor and activating a controller for adjusting the pressure to a set point based on the data obtained by the comparison. The apparatus includes a hydraulic compressor adapted for pressing cell members together, a pressure sensor for measuring the pressure inside the electrolysis cell, a pressure sensor for measuring the pressure in the compressor, and a controller for controlling the amount of hydraulic fluid to and from the compressor.

Abstract: A spindle shaper machine tool successively performs a plurality of operations on a work piece without removal and replacement of cutter heads on the spindle. The cutter heads are superimposed on the spindle, a fluid pressure jack quickly shifts the spindle to align a selected head with a work piece and the work piece is either manually or automatically advanced across the rotating selected tool. In the automatic shaper tool, a collar bearing stop for each cutter head is also provided on the spindle to abut the work piece or a template controlling the cutting of the work piece. The jack can be manually actuated by the operator or automatically actuated at the completion of a cutting cycle. Various combinations of cutter heads and bearing stop sets are mountable on the spindle to perform selected operations such as rough and finishing cuts, heavy-duty and light cuts, cutting and sanding, adding or modifying cuts and the like.
