    Abstract: PROBLEM TO BE SOLVED: To provide a suitable bimetallic tube for the tube bundle unit of heat exchanger, the unit which is operated under the high pressure condition and the high aggressive condition of erosiveness and corrosiveness. SOLUTION: The unit consists of at least one tubular part of the first metal which is tolerant to the corrosive and/or erosive action of the treated fluid in contact, and the tubular component is a bimetallic tube having a near area to one covered end with the second metal layer at least or the distal end when the exterior is seal welded to the different support body from the first metal. Moreover, the tube bundle unit is used for handling the heat exchanger in high temperature and high pressure under the conditions of high aggressive treated fluid, and the tube bundle contains at least one tube having the above characteristics. The unit is used especially as a dissolution unit in a cycle of the heat exchanger mechanism and a urea composition process of high pressure, high temperature, and high aggressive condition of the treated fluid, and the tube bundle contains at least one tube having the above characteristics.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a synthetic gas from a heavy charge with stable function of the system, almost no problem in foaming and no difficulty in adjusting a water level, in a cooling separation process of a method for producing a synthesis gas by partially oxidizing the heavy charge such as heavy crude oil, distillation residue or the like.
    SOLUTION: The method for producing the synthesis gas includes a process in which the heavy charge is partially oxidized at ≥1,000°C and ≥20 atm. in the presence of steam using oxygen or a highly oxygen-containing air, the obtained synthetic gas 1 is cooled by directly pouring water 2 to the synthesis gas 1, subsequently cooled gas 4 and water 3 are separated through a ring formed between an adduction tube TA and a concentric tube TC installed around the adduction tube and having both open ends. The distance (L) between the lower end of the adduction tube and the lower end of the open concentric tube is equal to or larger than x [x is expressed by x=0.026F+0.15 and varies depending on a gas flow ratio (F)(expressed by kg/h/cm
    2 )] times of the diameter (D) of the lower end of the adduction pipe.
