English

Subject field(s)
  • Oil Production
  • Metrology and Units of Measure
DEF

[The] throughput of oil expressed in barrels processed during one day when the plant is running the whole of the time. [Definition standardized by ISO.]

CONT

BPCD : Barrels per calendar day. Measure of the rated capacity of a process unit or operation. Defined as 1/365 th of the annual throughput. This measure accounts for down time for maintenance, etc. An alternate measure is barrels per stream day [BPSD], the measure of the maximum daily capacity. On-stream factor is the ratio of BPCD to BPSD.

OBS

barrels per stream day: term standardized by ISO.

OBS

barrels per stream day: term rarely used in the singular (barrel per stream day).

Key term(s)
  • barrel per stream day

French

Domaine(s)
  • Production pétrolière
  • Unités de mesure et métrologie
DEF

Quantité de produit pétrolier, exprimée en barils, traitée par jour en régime permanent. [Définition normalisée par l'ISO.]

OBS

barils par jour de marche : terme normalisé par l'ISO.

OBS

barils par jour de marche : terme rarement utilisé au singulier (baril par jour de marche).

English

Subject field(s)
  • Industrial Techniques and Processes
  • Computer Mathematics
CONT

When specifying a mass flow control system, the first consideration is whether the process will take place at constant system pressure, constant throughput, and/or predetermined gas flow ratio. Another important consideration is whether system control will be automatic(microprocessor) or manual(setpoint potentiometers).... There are three major state-of-the-art systems that can be identified. The first uses a flowmeter(s)... as the primary transducer(s) to monitor mass flow. Using this format, a signal is compared in control circuitry to a setpoint signal. This generates an error voltage which is used to drive a valve, thus continuously controlling the flow. The second major type of system uses a pressure transducer as the primary sensing element. System pressure is held either constant or varied at a predetermined rate by controlling the mass flow rate of process gases. This leads to a third type of system that slaves valves and flowmeters to the primary sensing.

English

Subject field(s)
  • Production (Economics)
  • Financial and Budgetary Management
CONT

The concept of productivity recognizes the interplay between various factors in the workplace. The output or results achieved may be related to different inputs or resources in the form of various productivity ratios, for example, output per labour hour, output per unit of material(as in kilometres driven per litre of gas) or output per unit of capital. Each of these productivity ratios may be influenced by a combination of factors, such as quality and availability of materials, scale of operations, rate of capacity utilization, availability and throughput capacity of capital equipment, attitude and skill level of the work force, motivation and effectiveness of the management. The manner in which these factors interrelate will have a bearing on the resulting productivity ratio.

CONT

Les fondamentaux nécessaires pour qu'une économie soit saine, sont les coefficients d'épargne, les coefficients d'investissements, les ratios de productivité et la balance des paiements.

Record 7 1993-03-10

English

Subject field(s)
  • Biological Sciences
  • Biomass Energy
OBS

anaerobic filter system. A technology used in anaerobic digestion suited to liquid effluents with high levels of dissolved organic matter and relatively low levels of particulate solids. In an anaerobic filter, the biomass is retained by trapping or immobilizing on a fixed carrier which may be in the form of large plates, specially designed random plastic supports, or broken pieces of rock or similar material. The reactor may be run as a continuous process in either an upflow or a downflow mode. Retention of the cells on a support gives a high ratio of solids retention time to hydraulic retention time, permitting high rates of throughput.

French

Domaine(s)
  • Sciences biologiques
  • Énergie de la biomasse
DEF

Type de réacteur dans lequel la réaction catalytique s'effectue à l'aide d'un filtre anaérobie.

OBS

Le filtre anaérobie. Les systèmes sont généralement du type filtre immergé «upflow». Le support utilisé pour la fixation des microorganismes est généralement un matériau naturel (type gravier) ou artificiel (type anneaux plastiques). La fixation des bactéries permet de travailler avec des temps de séjour très courts en conservant une grande stabilité de fonctionnement. L'activité des microorganismes est importante et permet d'obtenir des résultats intéressants sur tous les types d'effluents liquides, les taux de charge sont 3 à 10 fois plus importants qu'en procédé contact.
