Refrigerated tank

Large quantities of butane are shipped under contract standards rather than under national or worldwide specifications. Most of the petrochemical feedstock materials are sold at purity specifications of 95—99.5 mol %. Butane and butane—petroleum mixtures intended for fuel use are sold worldwide under specifications defined by the Gas Processors Association, and the specifications and test methods have been pubHshed (28). Butanes may be readily detected by gas chromatography. Butanes commonly are stored in caverns (29) or refrigerated tanks. 

Crea.m Yeast. At a 5% soHds concentration in the fermentor, the yeast occupies about 12% of the fermentor volume. It is harvested by centrifugation in nozzle centrifuges and washed several times with water. The final centrifugate is cooled and stored in refrigerated tanks. This yeast cream (so called because of its off-white color) may be sold directly in this form, since in large baking faciHties, it may be piped directly to any desired location. 

At about 12 40 A.M. December 3, 1984, the accident occurred that took 2,500 lives at the Union Carbide (India) Ltd. (UCIL) operated pesticide plant. The first indication of process upset was when the control-room operator (CRO) noted that the temperature in a supposedly refrigerated tank storing methyl isocyanate gas (MIC), had risen to 77° F. The pressure, normally 2 to 25 psi was 55 psi. 

Note Above 2800 square feel of weiied surface area, the total heat absorption is considered to remain constant for nonrefrigerated tanks below I pound per squa. e inch gage. For nonrefrigerated tanks above I pound per square inch gage and for all refrigerated tanks, the total heat absorption continues to increase with wetted surface area. This is the reason why the curve splits above 2800 square feel.

For refrigerated tanks the total venting requirement is the value determined from Table 7-17, multiplied by the environment factor F from Table 7-18. For tanks greater than 2,800 ft. exposed wetted surface, use the venting formula for V,. (Equation 7-49). Do not apply the factors from Table 7-18.

Pressurized storage vessels are either refrigerated tanks (low pressure) or horizontal vessels and spheres for storing lighter material under pressure so they remain liquids. 

Modern pipeline milking systems convey the milk into a refrigerated tank equipped with mechanical agitation to cool it rapidly and maintain it at < 5°C. Milk is normally held on the farm for 24-72 hr and is then transported to the processing plant. Upon arrival at the processing plant, milk is examined for temperature, flavor, and acidity. It is then sampled and tested for fat, total solids, and antibiotics content. If acceptable, the milk is received and stored in refrigerated tanks until it is processed further. 

Having a high critical temperature, nitrous oxide can exist as a liquid at room temperature (5.01 MPa at 294 K). Commonly, it is stored and transported in the liquefied state under pressure in steel cylinders or refrigerated tanks. 

Loss of containment of a liquefied gas under pressure and at atmospheric temperature, however, causes immediate flashing of a large proportion of the gas, followed by slower evaporation of the residue. This is usually a more serious case than if a refrigerated tank is used. The hazard from a gas under pressure is normally much less in terms of the amount of material stored, but the physical... 

Milk required for the production is received in a similar manner and pasteurized before storage in a refrigerated tank until required for batching. A portion of the milk may be used for combining with salt for brine milk. 

Because methane exists as a gas at normal temperatures and pressure, exposure generally occurs by inhalation. It is possible to spill liquid methane from a refrigerated tank, causing frostbite upon contact with the skin due to rapid evaporation and loss of heat. 

Bakers may use egg products in liquid, dried, or frozen forms. Liquid eggs, which have been churned, filtered, and pasteurized by the egg producer, are available in refrigerated tank cars to the large wholesale bakeries. The quality of dried egg products have been immensely improved in recent years, and many types of dried eggs are widely used by U.S. bakers in their production of bakery foods. Frozen egg products have lost ground to dried eggs because the former require careful thawing, a tedious, labor-intensive, and sometimes uncertain process.
