METHOD AND APPARATUS FOR ESTIMATING FOULING FACTOR AND/OR INVERSE SOLUBLE SCALE THICKNESS IN HEAT TRANSFER EQUIPMENT

Номер: US20140177673A1
Автор: BLISS TERRY LYNN, PATTERSON TIMOTHY FREDERICK
Принадлежит: Hercules Incorporated

Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor positioned on and projecting through a conduit wall. The sensor consists of a conductive block containing a heater and having a heated wetted test surface that is flush with the inside of the conduit wall and in contact with the flow through the conduit. Within the conductive block are two temperature sensors which are at different distances from the heated wetted test surface and the heater. The periphery of the apparatus is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface. By comparing the temperature differential between the two temperature sensors to the differential when no scale is present, the presence of and amount of scale can be determined, based on reduced heat transfer through the heated wetted surface caused by the accumulated scale. The change in the temperature differential is directly proportional to the scale thickness for a given type of scale. When the thickness of the scale is determined by another means, the nature of the scale can be implied. The sensitivity of the measurement can be adjusted to accommodate a very wide range of bulk liquid or ambient temperature via adjustment of the heat flux through the provided secondary heat flux path. 1.

A method of controlling cooling water treatment may involve measuring operating data of one or more downstream heat exchangers that receive cooling water from the cooling tower. For example, the inlet and outlet temperatures of both the hot and cold streams of a downstream heat exchanger may be measured. Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger. The heat transfer efficiency can be trended over a period of time and changes in the trend detected to identify cooling water fouling issues. Multiple potential causes of the perceived fouling issues can be evaluated to determine a predicted cause. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the predicted cause of the fouling. 1. A method comprising:monitoring, by one or more processors, a heat transfer efficiency of at least one heat exchanger and establishing a heat transfer efficiency trend for the heat exchanger, the heat exchanger having a process stream-side and a cooling water stream-side;detecting, by the one or more processors, a change in the heat transfer efficiency trend;receiving, by the one or more processors, data indicative of scale fouling on the cooling water stream-side;receiving, by the one or more processors, data indicative of corrosion fouling on the cooling water stream-side;receiving, by the one or more processors, data indicative of biofouling on the cooling water stream-side;determining, by the one or more processors, a predicted cause of the detected change in the heat transfer efficiency trend based at least on the received data indicative of scale fouling, corrosion fouling, and biofouling; andcontrolling addition of a chemical additive into a cooling water that is in fluid communication with the cooling water stream-side of the at least one heat exchanger based on the predicted cause.2.
