摘要： A variable mode microwave water cut monitor includes a test cell which contains a fluid sample. Apparatus controls the provision and removal of the fluid sample to effect different modes of operation for the monitor, a normal test mode and at least two calibration modes. A source provides microwave energy to one of a first antenna which in turn provides the fluid sample in the test cell with microwave energy. A second antenna receives the microwave energy that has passed through the fluid sample. A detector detects the received microwave energy and provides a signal corresponding thereto. An indicator provides an indication of the water cut of the fluid sample in accordance with the received signal power, a phase difference between the source provided microwave energy and the received microwave energy and internally recorded calibration data for water alone and oil alone.

摘要： A petroleum stream microwave water cut monitor includes test cell means which contains a reference petroleum multiphase fluid sample and which has a sample stream of a petroleum stream passing through it. A source transmits microwave energy to one of a first pair of antennae which irradiates the petroleum stream flowing in the test cell or the reference sample in the test cell with microwave energy. One of a second pair of antennae receives the microwave energy that has passed through either the petroleum stream or the reference sample. A detector detects the received microwave energy and provides a signal corresponding thereto. An indicator provides an indication of the water cut of the petroleum stream in accordance with the received signal power and a phase difference between the transmitted microwave energy and the received microwave energy.

摘要： The watercut of fluid in a mulitphase flow is measured. Microwave energy in the 10 Ghz range is transmitted through a test call having flow passing therein through a known geometry. Attenuation and phase shift of the microwave energy is measured and used to derive the wave number of the microwaves in the unknown fluid. The water fraction of the unknown fluid is then determined from the wave number and the known geometry of the test all using Hannai's equation.

摘要： Variant xanthan gums are provided which include a water-soluble polysaccharide polymer comprising repeating pentamer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:2:1, and a water-soluble polysaccharide polymer comprising repeating tetramer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:1:1. The D-glucose moieties are linked in a beta- 1,4! configuration. The inner D-mannose moieties are linked in an alpha- 1,3! configuration, generally to alternate glucose moieties. The D-glucuronic acid moieties are linked in a beta- 1,2! configuration to the inner mannose moieties. The outer mannose moieties are linked to the glucuronic acid moieties in a beta- 1,4! configuration. Processes for preparing the polysaccharide polymers are also provided.

摘要： In a three phase fluid stream microwave monitor, an improved test cell having a fluid stream flowing through it with spaced, aligned first and second antenna located within the test cell to receive microwave energy, irradiate the fluid stream, and receive the microwave energy which has passed through the fluid stream. The test cell has a rotatable cage mounted to form a cylinder enclosing the antennas for reducing an amount of debris in a portion of the petroleum stream flowing therebetween. The cage includes vanes which cause it to rotate, under the influence of the flowing stream to thereby be self-cleaning. The cage also carries a block which lies between the antenna and perpendicular to the axis thereof. Rotation of the cage causes rotation of this block to modulate the microwave transmission in a manner indicative of the fluid velocity.

摘要： A petroleum stream microwave watercut monitor of the present invention includes a test cell having a petroleum flowing through it. A source, connected to a first antenna located within the test cell, provides microwave energy to the first antenna so as to irradiate the petroleum stream in the test cell with microwave energy. A second antenna located in the test cell and connected to a detector outside of the test cell receives the microwave energy that has passed through the petroleum stream and provides it to the detector. The detector provides an intensity signal corresponding to the received microwave energy. An indicator provides an indication of the watercut of the petroleum stream in accordance with the intensity and the phases difference between the microwave energy provided by the source and the received microwave energy. The test cell means also includes means for reducing an amount of debris in a portion of the petroleum stream flowing between both antenna.

摘要： The petroleum stream watercut monitor includes a test cell having a petroleum stream flowing through it. A microwave transmitter provides microwave energy through an antenna through an isolator. The antenna irradiates the test cell with the microwave energy so that the microwave energy enters the test cell and is reflected from the petroleum stream back to the antenna. A circulator connected to the isolator connects the transmitter to the isolator means and provides microwave energy to the antenna through the isolator and receives from the antenna again through the isolator the reflected microwave energy. An indicator provides an indication of the watercut of the petroleum stream in accordance with the phase difference between the transmitted microwave energy and the test microwave energy.
