The restraint system also includes a first linkage having a first end and a second end, and a second linkage having a first end and a second end. The restraint system includes a second restraint having a third collar portion and a fourth collar portion. The restraint system further includes a third fastener and a fourth fastener. The first ends of the first and second linkage couple to the first restraint and the second ends of the first and second linkage couple to the second restraint.

The present invention utilizes mechanical vapor compression and/or thermal vapor compression integrating compression loops across multiple process stages. A sequential network of compressors is utilized to increase the pressure and condensing temperature of the vapors within each process stage, as intra-vapor flow, and branching between process stages, as inter-vapor flow. Because the vapors available are shared among and between compressor stages, the number of compressors can be reduced, improving economics. Balancing vapor mass flow through incremental compressor stages which traverse multiple process stages by splitting vapors between compressor stages enables the overall vapor-compression system to be tailored to individual process energy requirements and to accommodate dynamic fluctuations in process conditions.

Embodiments of an injection device shaped in order to atomize a liquid into droplets by means of a gas are disclosed herein. The injection device may comprise a body having a gas inlet orifice intended to be connected to a gas supply duct. The injection device may further comprise an outlet orifice for discharging the atomized liquid. The injection device may also comprise a straight internal duct connecting the inlet orifice to the outlet orifice along an axial direction of said body. At least two liquid inlet ducts may be intended to be connected to at least one liquid supply duct pass through said body radially or substantially radially and open into said internal duct. These liquid inlet ducts may each have an axis and are arranged so that their axes intersect at one and the same point on an axial line extending inside the internal duct.

A system and process for producing synthetic gas from solid fuel comprising waste material, municipal solid waste or biomass, and for upgrading the synthetic gas produced. The system and process utilizes a first thermal chamber having a gasification zone in which a fuel stream is gasified by thermal oxidation to produce a first synthetic gas stream and heat; a pyrolysis reactor housed within the first thermal chamber where fuel undergoes pyrolysis to produce a second synthetic gas stream; and a thermal catalytic reactor comprising a second thermal chamber having a catalyst chamber within with a selected catalyst. The first synthetic gas stream is completely thermally oxidized to produce high temperature flue gas that imparts heat to the catalyst chamber in which the second synthetic gas stream is thermally cracked and directed over the catalyst to yield a finished gas or liquid product having a desired chemical composition as determined by the selected catalyst.

This disclosure provides systems and methods that utilize integrated mechanical vapor or thermal vapor compression to upgrade process vapors and condense them to recover the heat of condensation across multiple processes, wherein the total process energy is reduced. Existing processes that are unable to recover the heat of condensation in vapors are integrated with mechanical or thermal compressors that raise vapor pressures and temperatures sufficient to permit reuse. Integrating multiple processes permits vapor upgrading that can selectively optimize energy efficiency, environmental sustainability, process economics, or a prioritized blend of such goals. Mechanical or thermal vapor compression also alters the type of energy required in industrial processes, favoring electro-mechanical energy which can be supplied from low-carbon, renewable sources rather than combustion of carbonaceous fuels.
