  • Patent number: 10995050
    Abstract: A process for purification of a crude product stream recovered from the production of an unsaturated carboxylic acid by an aldolization reaction is disclosed. The product stream comprises the unsaturated carboxylic acid, aldehyde, saturated carboxylic acid, water, non-condensable vapours and optionally heavy by-products. The process comprises: providing the crude product stream in the vapour phase to a first separation column operated at a temperature and pressure to form an intermediate product stream comprising product unsaturated carboxylic acid, a portion of the water from the feed stream, a portion of the saturated carboxylic acid and heavy by-products where present; and passing the intermediate product stream to a second separation column operated at a temperature and pressure such that the unsaturated carboxylic acid product is separated and recovered.

  • Patent number: 10995063
    Abstract: Methods and machinery are described for combining methane with sulfur trioxide to make MSA, in a system that sustains optimal concentrations of reactants in the main reactor for high yields, efficiency, and profitability. Rather than simply making MSA and then removing it, this design uses a “continuous loop system” with: (i) a “rich acid” stream containing a high concentration of MSA, mixed with sulfuric acid, which will emerge from the main reactor, and (ii) a “reduced acid” stream containing a low concentration of MSA (still mixed with sulfuric acid), from an extractor unit (such as a distillation unit) which removes some but not all of the MSA from the “rich acid”. Additional subassemblies are described which enable the main reactor to work efficiently, at a sustained high flow-through capacity. This system also can be scaled up or down, for any daily MSA production rate.

  • Patent number: 10981856
    Abstract: A cannabis infused oil is formed by collecting and drying raw cannabis material having a desired cannabinoid profile. Next, the raw dried cannabis material is blended with oil to obtain a cannabis infused oil mixture. Blending is performed without causing the cannabis material to become decarboxylated. Next, the cannabis material is filtered from the cannabis infused oil mixture thereby obtaining a cannabis infused oil. The cannabis infused oil has at least two cannabinoids present in the oil in accordance with the desired cannabinoid profile. Next, the cannabis infused oil is packaged for storage and shipment. The cannabis infused oil is formed without any alcohol, does not have any decarboxylated cannabinoids and is non-psychoactive. In one example, the cannabis infused oil has between 100 milligrams and 2,000 milligrams of cannabinoids per fluid ounce of cannabis infused oil. In another example, before blending with oil, the cannabis material is combined with alcohol.

  • Patent number: 10981863
    Abstract: A method and a production system for recovering and treating taurine mother liquor, which is used for the process of ethylene oxide taurine production process. As for the treatment of the last mother liquor of taurine, add alkali firstly to the last mother liquor of taurine and then acid to form salt, or add salt directly; then concentrate and crystallize and filter, to remove lots of impurities in taurine mother liquor. This solves the problem of separating impurities, greatly shortening the time of removing impurities. The last mother liquor can also be decolorizes and additional impurities removes by activated carbon, and the removal of salt by mixing ammonia into the mother liquor to obtain the pure taurine mother liquor, thereby recovering the mother liquor and increasing the product yield.

  • Patent number: 10968414
    Abstract: A method for refining vegetable oil is used to reduce formation of soaps. An acid-treated vegetable oil mixture is passed through a low shear mixing device prior to being fed to a static hydrodynamic reactor. The static hydrodynamic reactor induces a neutralization reaction that forms soaps in a pressurized vegetable oil mixture. The reacted mixture is discharged from the reactor to a downstream system for separating the formed soaps from the reacted mixture to form a refined vegetable oil having reduced soaps content.
