1. A gasification system for gasification of a solid powder, comprising:
- a storage tank configured to receive a solid powder and a first gas to form a gas-solid mixture in the storage tank;
a pipeline, wherein the gas-solid mixture is conveyed from the storage tank into a tubular element of said pipeline; and
a gasifier, wherein the gas-solid mixture is introduced from the pipeline into the gasifier for gasification of the gas solid mixture;
wherein the pipeline comprises;
the tubular element in fluid communication with the storage tank and the gasifier,a containment element defining a cavity to accommodate a portion of the tubular element, andan inlet of containment element in fluid communication with the cavity and with an interior of the tubular element through the portion of the tubular element accommodation within the cavity,wherein the tubular element comprises a bended portion disposed within the cavity of the containment element, and wherein at least a portion of a sidewall of the tubular element is a porous sidewall;
wherein the inlet of the containment element is configured to introduce gas into the cavity to increase a pressure in the containment element so that said gas can be pressurized into the tubular element through the porous sidewall;
wherein the tubular element of the pipeline is configured to convey the gas-solid mixture from the storage tank into the gasifier for gasification of the gas-solid mixture.

Abstract
A pipeline for conveyance of a multiphase fluid is provided. The pipeline comprises a containment element and a tubular element. The containment element defines a cavity and an inlet in fluid communication with the cavity. The tubular element passes through the containment element and with a portion thereof disposed within the cavity to be in fluid communication with the inlet of the containment element. A gasification system for gasification a solid powder and a method for conveyance of a multiphase fluid are also presented.
