Abstract: A cleaning device for cleaning an orifice in a condensate removal device that is capable of use while the condensate removal device is on-line, i.e. during operation. In one aspect, the cleaning device provides a reciprocally movable cleaning rod that can be retractably insertable into the orifice. This can be done without affecting the sealed volume defined around the orifice. In another aspect, the cleaning device includes a retractable hood or shield over the cleaning rod, to protect when not inserted in the orifice.

Abstract: A method for modernizing an ammonia synthesis loop (1) with a first converter (10) and a second converter (11) in series, the first converter (10) comprises a cartridge with one or more catalyst beds, the second converter (11) comprises a catalyst bed in direct contact with said vessel, the method comprising the steps of removing the second converter, and boosting the first converter by replacing the cartridge with a high-efficiency cartridge comprising a plurality of adiabatic catalyst beds and inter-bed heat exchangers, or an isothermal catalyst bed, and by reducing the concentration of inerts in said first converter.

Abstract: An exothermic heterogeneous catalytic synthesis reactor including at least one catalytic bed 5a-5c arranged in a cylindrical shell 2 and provided with a bottom plate 6a-6c for containment of the catalyst, and at least one supporting shoulder 7a-7c for the bottom plate 6a-6c extending from the shell 2, includes a catalyst-seal support device including an annular element 17, 25 placed between the shoulder 7a-7c and the bottom plate 6a-6c. The annular element 17, 25 is fixed in a removable manner with the bottom plate 6a-6c and has a thermal expansion coefficient substantially equal to that of the shell 2.

Abstract: A disposable, metal beverage can having a easy-opening tab on the top of the can. A second easy-opening tab is disposed on the can generally opposite the first easy-opening tab. The second tab is located on the bottom of the can or on the side of the can near the bottom. The first tab is opened to pour out the beverage by raising the bottom above the top. The second tab is then opened so that air enters the can above the beverage for rapid and regular emptying of the can while avoiding splashing of the beverage during pouring.
