n: The capacity that rock resists condensation.

n: a light hydrocarbon liquid obtained by condensation of hydrocarbon vapours. It consists of varying proportions of butane, propane, pentane, and heavier fractions, with little or no methane or ethane.

the part of the hydrocarbon stream that is a vapor in the formation and condenses to a liquid after being cooled. Normally the volatile condensate has a composition of C5 to C8 and an API gravity of >40.

n: the process by which vapours are converted into liquids, chiefly accomplished by cooling the vapours, lowering the pressure on the vapours, or both. Condensation is often the cause of the presence of water in fuels.

n: a high-pressure stainless steel or nickel-plated brass chamber with a magnifying window, a sample inlet. a pressure gauge, a tripod socket. a gas outlet. and an angle-mounted mirror. It ascertains dew point by observing the temperature and the pressure at which condensation occurs on and disappears from the mirror.

n: a compressible fluid that completely fills any container in which it is confined. Technically, a gas will not condense when it is compressed and cooled, because a gas can exist only above the critical temperature for its particular composition. Below the critical temperature, this form of matter is known as a vapour, because liquid can exist and condensation can occur. Sometimes the terms gas" and "vapour" are used interchangeably. The latter, however, should be used for those streams in which condensation can occur and that originate from, or are in equilibrium with, a liquid phase.

n: an igneous rock that, while molten, penetrated into or between other rocks and solidified.

n: a kinds of eruptive rock that formed by condensation of other rock beause of magma inbreak.

n: 1. gas that is taken in succeeding years and has been paid for previously under a take-or-pay clause in a gas purchase contract The contract will normally specify the number of years after payment in which the purchaser can take delivery of make-up gas without paying a second time. 2. gas injected into a reservoir to maintain a constant reservoir pressure and thereby prevent retrograde condensation. 3. in gas processing, the gas that makes up for plant losses. During processing there is a reduction in gas volume because of fuel and shrinkage. Some agreements between gas transmission companies and plant owners require plant losses to be made up or to be paid for.

n pi: thermosetting plastic materials formed by the condensation of phenols (containing C6HsOH) with aldehydes (containing CHO) and used as protective coat- ings for oilfield structures.

n: a thermosetting or thermoplastic rnaterial formed by esterification of polybasic organic acids with polyhydric acids.

resin formed by condensation of polybasic and monobasic acids with polyhydric alcohols.
