  • Patent number: 10435487
    Abstract: A process for separation of a hydrocarbon-containing feed stream can include cooling the hydrocarbon-containing feed stream using an absorption refrigeration cycle to form a cooled feed stream. The cooled feed stream can be subjected to distillation conditions to remove a bottom stream including co-monomer; and an overhead stream including hydrocarbon diluents, olefin monomer, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead stream can be subjected to distillation conditions adapted to remove a bottom stream including substantially olefin-free hydrocarbon diluents; a side stream including hydrocarbon diluent; and an overhead vapor stream including olefin monomer, diluents, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead vapor stream can be cooled using an absorption refrigeration cycle to form a cooled overhead vapor stream. Olefin monomers can be separated from diluents in the cooled overhead vapor stream.

  • Patent number: 10300316
    Abstract: The present invention concerns a method to mitigate the consequences of an unconfined or partially confined vapor cloud explosion due to the accidental release of a flammable gas in an open area, wherein: means capable to release a flame acceleration suppression product are dispersed in said area, a signal is generated by a detector of said flammable gas release, or by an operator, or by an approaching flame or by the explosion itself, or by any combination thereof, said signal activates the release of the flame acceleration suppression product in said area and in a sufficient amount to transform the flammable cloud into a mixture of flammable product, air and said flame acceleration suppression product to prevent flame accelerations in an unconfined vapor cloud explosion but to let the flammable product burn in case of ignition.

  • Publication number: 20140114105
    Abstract: A process can include making a bio-diesel, a bio-naphtha, and optionally bio-propane from a complex mixture of natural occurring fats & oils. The complex mixture can be subjected to a refining treatment for removing a major part of non-triglyceride and non-fatty acid components to obtain refined oils. The refined oils can be subjected to a fractionation step to obtain a substantially unsaturated liquid triglyceride part (phase L), and a substantially saturated solid triglyceride part (phase S). The phase L can transformed into alkyl-esters as bio-diesel by a transesterification. The phase S can be transformed into substantially linear paraffin's as the bio-naphtha by an hydrodeoxygenation. Fatty acids can be obtained from the phase S and transformed into substantially linear paraffin's as the bio-naphtha by hydrodeoxygenation or decarboxylation. Fatty acids soaps can be obtained from the phase S that are transformed into substantially linear paraffin's as the bio-naphtha by decarboxylation.

  • Publication number: 20140088272
    Abstract: The invention relates to a process for preparing polyolefin in a loop reactor. The polymer is prepared by polymerizing olefin monomers in the presence of a catalyst to produce a polyolefin slurry while pumping said slurry through said loop reactor by means of a pump. The present process is characterized in that the catalyst is fed in the loop reactor at a distance to the pump. The invention allows production of the polymer with advantageous properties while leading to fewer blockages of the reactor.
