Patent CA-2927530-A1 (CA)
Inventor: JUKKALA ESKO
IPC: H04B11/00
Filed: 2014-10-15
Abstract: A method comprises transmitting (901) a first ultrasonic ping signal from a first floating unit (M1). The first ultrasonic ping signal is received in an underwater device (D1, D2, D3). After a predetermined delay from the reception of the first ultrasonic ping signal, the underwater device transmits (905) a second ultra- sonic ping signal from the underwater device. The second ultrasonic ping signal is received in the first floating unit. The first floating unit determines a time difference between a time of transmission of the first ultrasonic ping signal from the first floating unit and a time of reception of the second ultrasonic ping signal, and based on the time difference, provides location information and/or other information to the underwater device by transmitting (910) to the underwater device sequential underwater ultrasonic ping signals such that time differences between the sequential underwater ultrasonic ping signals indicate the provided information.

Title: Hydrocracking of gas oils with increased distillate yield
Inventor: VIJAY ROHIT
IPC: C10G65/12
Filed: 2014-11-14
Abstract: Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.
