Intermediate heat transfer medium

The effect of sodium on the structural materials of interest has also been extensively studied, since sodium is proposed for use as the intermediate heat-transfer medium. Corrosion problems inherent in the utilization of sodium for heat-transfer purposes do not involve so much the deterioration of the metal surfaces as the tendency for components of the container material to be transported from hot to cold regions and to form plugs of deposited material in the cold region. As in the case of the corrosion by the salt mixture, the mass transfer in sodium-containing systems is extremely dependent on the maximum stem operating temperature. The results of... 

Other Chlorobenzenes. The market for the higher chlorobenzenes (higher than di) is small in comparison to the combined mono- and dichlorobenzenes. Trichlorobenzenes are used in some pesticides, as a dye carrier, in dielectric fluids, as an organic intermediate and a chemical manufacturing solvent, in lubricants, and as a heat-transfer medium. These are small and decreasing markets.

The heating and cooling system ensures rapid heating and cooling of the heat-transfer medium. The installation of additional intermediate silos for cooling the final polymer shortens the residence time of the polymer in the reactor and helps to increase its capacity. 

Chloroform is used primarily in the production of chlorodifluoromethane (hydrochlorofluorocarbon-22 or HCFC-22) used as a refrigerant for home air conditioners or large supermarket freezers and in the production of fluoropolymers (CMR 1995). Chloroform has also been used as a solvent, a heat transfer medium in fire extinguishers, an intermediate in the preparation of dyes and pesticides, and other applications highlighted below. Its use as an anesthetic has been largely discontinued. It has limited medical uses in some dental procedures and in the administration of drugs for the treatment of some diseases.

Chlorobenzene, also called monochlorobenzene, is a monocyclic aromatic compound. It is a colorless liquid with an aromatic almond-like odor and is manufactured for use as a solvent, is used in the production of other chemicals (pesticides), and in making certain other chemicals, rubber, dyes and grease solvents. It is used as a feedstock to produce ortho- and para- nitrochlorobenzenes and aniline as a solvent for paints and as a heat transfer medium. In the past, chlorobenzene was used as an intermediate in phenol and DDT production. Chlorobenzene enters the environment from industrial and municipal discharges. Another potential source is the formation and emission of chlorobenzene as a product of incomplete combustion in waste incinerators.

Intermediate system. The intermediate system, which also consists of six separate heat-transfer loops, utilizes sodium as the heat-transfer medium. All material of construction of the intermediate system, except the steam generator, is 2 % Cr-1% Mo steel. The steam generator, which is designed for high-pressure, high-temperature service, is constructed of type-304 stainless steel. The intermediate piping (12-in. schedule-30) is sized for a maximum sodium velocity of 17 fps.
