    Abstract: Both a system and method for cleaning a low pressure separation vessel of a high pressure polyethylene polymerization plant are provided. The system includes a polytetrafluoroethylene lining that covers the interior surfaces of the vessel, and a cover mounting assembly including an annular clamp for detachably mounting a cover over the vessel. The mounting assembly includes a clamp actuator for quickly securing and releasing the cover with respect to a top rim of the vessel. The vessel is drained of liquid polyethylene and allowed to cool to ambient temperature, thus creating a frozen “skin” of polyethylene around the interior surfaces of the vessel. The clamp actuator releases the cover. The polyethylene skin is peeled off the interior sides the vessel and gathered up at the top to form a neck, thus peeling the polyethylene skin away from the polytetrafluoroethylene lining along with any degraded polymers or other impurities that have accumulated on the interior surfaces of the vessel.

    Abstract: Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.

    Abstract: A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

    Abstract: A CVD or PVD coating device comprises a housing and a gas inlet organ secured to the housing via a retaining device, the gas inlet organ having a gas outlet surface with gas outlet openings. The retaining device is only secured at its horizontal edge to the housing so as to stabilize the retaining device with respect to deformations and temperature. The gas inlet organ is secured, at a plurality of suspension points, to the retaining device by means of a plurality of hanging elements distributed over the entire horizontal surface of the retaining device. The retaining device has mechanical stabilization elements formed by a retaining frame having vertical walls that are interconnected at vertical connection lines. An actively cooled heat shield is situated between the retaining device and the gas inlet organ.
