  • METHOD AND APPARATUS TO SELECT A PLANE IN A NAND FLASH DIE TO STORE A READ-ONLY RESERVED BLOCK
    Publication number: 20230266910
    Abstract: Manufacturing yield loss of NAND Flash dies is reduced by selecting a plane to store a read-only reserved block and another plane to store a backup read-only reserved block based on the Number of Valid Blocks (NVB) blocks in each plane in the NAND Flash array.

  • Staged hydrotreating and hydrocracking process and apparatus
    Patent number: 10358611
    Abstract: An apparatus and process is disclosed for hydrocracking a hydrocarbon feed stream following hydrotreating the feed stream. A separator removes diesel and lower boiling materials in a hydrotreated stream before a hydrocracking reactor, so only liquid materials heavier than diesel are hydrocracked in a hydrocracking reactor. A vapor hydrotreated stream and the hydrocracked stream are separated and fractionated together.

  • PROCESS AND APPARATUS FOR HYDROISOMERIZING A HYDROPROCESSED LIQUID STREAM
    Publication number: 20180370871
    Abstract: A hydroisomerization reactor is moved to a low pressure section downstream of a high pressure hydroprocessing unit. The hydroisomerization reactor can be easily taken off line during the warmer months when cold flow property specifications are less stringent. The hydroisomerization reactor is also operated at lower pressure than the hydroprocessing reactor requiring less capital and operating expense.
