摘要:The present invention relates to a new type of lining with two layers, one of which, obtained by welding deposit, can be used for the protection of internal surfaces of chemical equipment capable of abide pressures lower than 100 MPa, in processes for the direct synthesis of urea. The present invention also relates to an original method for the preparation and installation of this lining, by the assembly of laminar elements with two layers, obtained by welding deposit on relatively thin stainless steel plates, so as to avoid significant distorsion effects on the plate itself.

摘要:A method for repairing and restoring the functionality of equipment subjected to internal corrosion during its operation at high or medium pressure in a plant for the synthesis of urea. The method includes the cleaning of the corroded area, the formation of suitable supporting and/or holding surfaces for the placement of a new metallic lining, the formation of a new anticorrosive sealed off lining, obtained by positioning and welding flat elements and metallic plates which are suitably shaped and placed next to each other to become adapted to the internal profile of the equipment. The spaces and interstices below this new lining all communicate with at least one weep-hole present in the pressure resistant body. The entire repair is carried out through the manhole of the equipment and enables the restoring of its functionality for times similar to the normal duration of corresponding newly constructed equipment.

摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
