  • Publication number: 20230158479
    Abstract: The present invention addresses to a catalyst, and the method for obtaining the same, for generating hydrogen and/or syngas. More specifically, the present invention describes a catalyst based on nickel, molybdenum and tungsten, for steam reforming processes of natural gas or other hydrocarbon streams (refinery gas, propane, butane, naphtha or any mixture thereof) that presents high resistance to deactivation by coke deposition. According to the present invention, the catalyst has NiMoW as its active phase, in bulk form and/or supported on an alumina oxide and other high surface area oxide supports, and may also contain other promoters. Furthermore, the present invention teaches the production of a catalyst whose active phase of NiMoW has high activity for hydrocarbon steam reforming reaction.

  • Publication number: 20230115384
    Abstract: The present invention presents a system that allows mixing in a controlled way the streams exported by two-phase or three-phase separators, allowing the management of the phases according to the processing needs of the SPUs. The main idea is that the outlet streams of the subsea separation modules can be routed to different SPUs in order to optimize the processing capacity of the surface plant. It is capable of manipulating in real time process parameters such as GLR (Gas-Liquid Ratio), or GOR (Gas-Oil Ratio) or Water Cut (amount of water in oil) to generate the multiphase streams required by each SPU, using the own autogenous pressure of the process to carry out this adjustment, that is, without the need for pressure raising systems or artificial lifting (pumps, compressors, gas lift, etc.) of the export streams of the system. This is possible by means of a crossflow injection control system between the phases. However, the possibility of using pressure raising systems (pumps, compressors, etc.
