Title: Apparatus for, and method of, controlling sand production from an oil well.
Inventor: SKÅLAND AKSEL
IPC: E21B43/12
Filed: 2021-05-26
Abstract: A method of controlling sand production from an oil well, the method comprising the steps of: (a) providing a continuous output production flow from a wellhead of an oil well connected to an oil-containing reservoir, the output production flow comprising hydrocarbon-containing oil at an oil production rate and sand at a sand production rate, and the output production flow being conveyed by a pipeline from the wellhead to a facility for processing, transporting by pipeline, or storing the oil; (b) at a sand management station along the pipeline between the wellhead and the facility, passing the output production flow through a sand management system installed in the pipeline, wherein the sand management system comprises a solids separator configured to separate sand from the oil of the output production flow, wherein the sand management system has an input which receives the output production flow from the wellhead along an upstream part of the pipeline, the upstream part being upstream of the sand management system, and an oil output which outputs the oil, having sand separated therefrom, along a downstream part of the pipeline, the downstream part being downstream of the sand management system; (c) opening a choke of the wellhead to increase the oil production rate and sand production rate, whereby the sand production rate is increased to a level higher than an allowable sand rate (ASR) which is a predetermined maximum threshold sand production rate of the pipeline, and, at least during a time period when the sand production rate is higher than the allowable sand rate (ASR), continuously or continually separating sand in the output production flow from the oil of the output production flow using the solids separator of the sand management system to provide a zero or non-zero reduced sand flow in the downstream part of the pipeline; (d) after or during step c), measuring sand flow in at least one of the sand management system and the downstream part of the pipeline to provide a reduced sand flow rate, which is a flow rate of the reduced sand flow, in the downstream part of the pipeline; (e) comparing the reduced sand flow rate with the allowable sand rate (ASR) to provide a sand rate comparison value; and (f) controlling the oil production rate using the sand rate comparison valueto maintain the reduced sand flow rate in the downstream part of the pipeline below the allowable sand rate (ASR).

Abstract: The present invention relates to an orifice member for the condenser fan of an air conditioning unit, which has a basepan and a partition which divides the air conditioning unit into an indoor section forwardly of the partition and an outdoor section rearwardly of the partition. The indoor section includes an evaporator coil, an evaporator fan and means for collecting condensate and directing the condensate to the basepan in the outdoor section. The outdoor section includes a condenser coil at the rear thereof, a rotatably driven condenser fan having a second side and a discharge side, the fan being located forwardly of the condenser coil. The orifice member defines a barrier between the suction and discharge side of the condenser fan and has a fan orifice opening forwardly of the fan to define a restricted air flow passage therethrough between the suction side at a generally low pressure and the discharge side at a generally high pressure. The condenser fan is an axial fan with blade s having tips extending from the suction side to the discharge side. The fan includes an annular slinger surrounding and having a portion secured to the blade tips in the region extending from the suction side to the discharge side. The tips and the slinger are located entirely rearwardly of the orifice member. The fan orifice and the slinger cooperate to define a first narrow annular passage therebetween. The slinger defines a second narrow annular passage with the underlying portion of the basepan, which is configured to collect condensate therein. The orifice member has a wall section underlying the fan orifice opening. The fan orifice opening has an imaginary vertically extending centerline and the wall section has an opening therein centered upon the centerline, which fluidly communicates the region of the basepan forwardly of the wall with both the first and second annular passages. The fluid opening has a narrow lateral dimension at the lower end thereof and a larger lateral di mension at the upper end thereof.

Title: Process for the cleavage of alkylaryl hydroperoxides.
Inventor: UWE TANGER
IPC: C07C37/08
Filed: 2001-10-12
Abstract: A process for the cleavage of alkylaryl hydroperoxides includes steps for producing a mixture of a concentrate that contains at least one alkylaryl hydroperoxide to be cleaved and a cleavage product obtained from the cleavage of an alkylaryl hydroperoxide, dividing this mixture into at least two parts and cleaving the alkylaryl hydroperoxides in parallel at different temperatures. One of the two parts is treated at a temperature sufficiently high for an integrated thermal post-treatment to be achieved. The process consumes less energy since less steam has to be used. Problems which can result from fouling in heat exchangers are largely prevented. No second feed point for alkylaryl hydroperoxide has to be provided. The process can be used in the preparation of phenol and acetone by the Hock method.

Title: Method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system.
Inventor: TIEDEMANN EDWARD G JR
IPC: H04B7/005
Filed: 2000-05-09
Abstract: A method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system. The method includes when the pilot signal is transmitted by the mobile station that is power controlled to a target receive level, the traffic channel power level is increased relative to the pilot channel to improve receiver performance. An improved feature is that the received pilot received at the base station stays the same while the receiver receives extra energy in the redundant traffic symbols received to enhance the probability of correctly decoding the received frame. The base station detects the absence of the mobile station transmitted signal from the frequency of interest. If the base station is aware of the starting time and duration of the absence, it can focus its detection during this predetermined time period. The performance can be improved if the absence of the signal is spread across two frames at the frame boundary.

Title: Method of isolating data in a power line communication network.
Inventor: KLINE PAUL
IPC: H04B3/56
Filed: 2001-01-19
Abstract: Isolating data in a power line communications system. Although plural subscribers receive electric power distributed from a common distribution transformer, it is desirable to isolate their branch lines from one another when those branch lines are used to conduct data communications as a supplement to electric power delivery. This isolation of branch lines is implemented in a centralized way at the distribution transformer, or alternatively, in a distributed way at each subscriber s premises. These implementations are made using low pass filters (which pass the power but block the data) and power line communications routers or power line communications repeaters.
