  • Patent number: 7951759
    Abstract: The present invention relates to transportable product for the transportation of paraffinic wax and methods of transporting using this transportable product. The transportable product comprises 90 to 20 weight % of a liquid comprising >50 weight % alcohol and having a true vapor pressure of ?14.7 psia when measured at 20° C., and 10 to 80 weight % of wax particles, wherein the wax particles comprise ?75 weight % of wax particles larger than 0.1 mm. The transportable product and methods of transporting according to the present invention are able to accommodate a relatively high weight % of paraffinic wax particles in the transportable product while avoiding interparticle adhesion and clumping by ensuring that the wax particles are not too small and the amount of small wax particles is not excessive.
    Type: Grant

  • Patent number: 6626122
    Abstract: The present invention relates to the use of deactivatable biocides in ballast water aboard a vessel. The present invention relates to methods of limiting the transfer of one or more life forms via ballast water comprising mixing an effective amount of the deactivatable biocide with the ballast water and irreversibly deactivating the deactivatable biocides before or upon discharge of the ballast water.

  • Patent number: 6518321
    Abstract: A transportable Fischer-Tropsch syncrude product and a method for manufacturing and (transporting and/or receiving) the product is disclosed. The product has a true vapor pressure of less than about 15 psia, preferably less than 11 psia, when measured at its transportation temperature, and includes at least 60% by weight, preferably at least 75% by weight, of linear hydrocarbons. The method involves converting a light hydrocarbon feedstock into syngas, converting the syngas to products via Fischer-Tropsch synthesis, and isolating a plurality of transportable products from the Fischer-Tropsch synthesis. The products have true vapor pressures of less than about 15 psia, preferably less than about 11 psia, when measured at their transportation temperature. At least one of the transportable products has a pour point in excess of 20° C. At least two of the products are transported separately in liquid form.
