Abstract: Disclosed is a process for vacuum distillation of a hydrocarbon stream comprising i) passing a hydrocarbon stream into a preflash vessel maintained under conditions to separate the hydrocarbon stream into a preflash liquid and a preflash vapor, ii) passing the preflash liquid into a vacuum furnace maintained under conditions to heat and partly vaporize the preflash liquid, iii) passing the heated furnace effluent into a zone located in the lower part of a vacuum distillation column maintained under fractionating conditions, and iv) passing the preflash vapor into the vacuum distillation column into a further zone located in the lower part of the vacuum distillation column.

Abstract: A method of controlling a direction of drilling of the drill string used to form an opening in a subsurface formation, comprises varying a speed of the drill string during rotational drilling such that the drill string is at a first speed during a first portion of the rotational cycle and at a second speed during a second portion of the rotational cycle wherein the first speed is higher than the second speed, and wherein operating at the second speed in the second portion of the rotational cycle causes the drill string to change the direction of drilling.

Abstract: A Floating Production, Storage and Offloading (FPSO) surveillance system (7) is equipped with an adjustable alarm threshold that suppresses nuisance alarms if liquid level variations in FPSO crude oil and/or other liquid storage tanks (6) monitored by the system do not exceed estimated oscillating liquid level variations due to oscillating motions of the FPSO unit (1) during severe weather conditions.

Abstract: Methods and systems for transferring feed materials between zones having substantially different pressures, where the transfer can be continuous or semi-continuous. The methods and systems include a plurality of lock hoppers to receive feed material from a low pressure zone and pressurize it with fluid to a pressure of a high pressure zone. The pressurized material can be discharged to a circulation loop, which carries the pressurized material to one or more receiving unit(s) of a pressurized system. At least some feed material remains in the receiving unit(s) and at least a portion of the fluid exits to become part of the circulation loop. After discharge, the lock hoppers can be depressurized so the next pressurization cycle can begin with additional feed material. The lock hoppers can be operated in a time-staggered manner to provide continuous or semi-continuous transfer of material.
