塔里木盆地塔河油田原油中双金刚烷分布特征与油气运移

研究了塔里木盆地塔河油田原油中双金刚烷的分布特征，探讨了该油田油气的充注期次和运移方向，结果表明，原油中双金刚烷指标值反映了原油的成熟度，并且指示研究区4区和6区原油充注时间较早、9区原油充注时间较晚，其它油区原油充注时间介于上述二者之间；原油中双金刚烷指标值分布特征显示出塔河油田下奥陶统油气存在2个充注方向，一是由南向北，并且油气成熟度相对较低，可能主要代表了早期的油气运移，另一个是由东向西，原油成熟度相对较高，可能主要代表了晚期的油气运移。根据原油成熟度和运移方向特征，认为塔河油田的早期油气起源于满加尔坳陷，晚期油气起源于满加尔坳陷和草湖坳陷，主力烃源岩层为寒武-奥陶系。

Performance of compression/absorption hybrid refrigeration cycle with propane/mineral oil combination

This paper discusses the feasibility of a vapor compression/absorption hybrid refrigeration cycle for energy saving and utilization of waste heat. The cycle employs propane as a natural refrigerant and a refrigeration oil as an absorbent. A prototype of the cycle is constructed, in which a compressor and an absorption unit are combined in series. The performance of the cycle is examined both theoretically and experimentally. Although the solubility of the propane with the oil is not enough as a working pair in the absorption unit, the theoretical calculation shows that the hybrid cycle has a potential to achieve a higher performance in comparison with a simple vapor compression cycle by using the waste heat. In the experiment, the prototype cycle is operated successfully and it is found that an improvement of an absorber is necessary to achieve the good performance close to the theoretical one. The application of an AHE (absorber heat exchanger) can reduce the heat input to a generator. Further examinations on some other combinations of refrigerant/refrigeration oil and additives are desirable.

MODELING WATER LOSS DURING FRYING OF POTATO STRIPS: EFFECT OF SOLUTE IMPREGNATION

The effect of solute impregnation on water loss and oil uptake during potato strip frying was studied. Blanched potato strips were impregnated at 25°C by soaking in a solution of sucrose-NaCl-water, 20-5-75% by weight. After rinsing and air drying, strips were deep fried in sunflower oil at 160, 170 and 180°C. A control treatment, consisting of potato strips blanched but not soaked and later air dried was also conducted. Solute impregnation provided a decrease of the oil uptake. Two models, based on Fick's law were used to describe water loss during frying. The first one is the classic model with an effective moisture diffusion coefficient assumed a constant value. The second model considers that diffusion coefficient varies during the frying process. For a given frying temperature, constant diffusion coefficient for control potatoes resulted in lower values than the impregnated ones. The variable diffusivity model showed a two-stage behavior: during the first stage of frying, diffusion coefficient increased with frying temperatures, but from a given time on an inverse behavior began. This last fact was found to be related to an increase of the measured peak force needed to penetrate the potato crust.
