The use of minicomputers as part of a product metering system is new and relatively expensive. The use of minicomputers is discussed from the following: 1) its advantage, practical limitations and disadvantages
In the report the problem leakage detection of petroleum and gas from trunking pipelines is solved. The basic questions for the detection of the fact of occurrence of leakage and definition of a place of its occurrence are presented. Their…
Since the high accuracy of the leakage detection can not be achieved at present, singularity analysis based on wavelet transform is adopted to analyze the pressure signals of the oil pipeline and then get the singularity points. To locate the…
A practical automatic system called ALDS (automatic leak detection system) is presented in this paper, which is implemented for leak detection of sealed radioactive sources used for oil well logging in oilfields. This ALDS is able to accomplish the…
The combination design of predictive functional control and PID method (PFC-PID) for liquid level of industrial coking equipment is presented. The control target is to maintain the liquid level of a coking fractionating tower within a set range by…
Pipelines transporting CO2 to crude oil producing fields for tertiary recovery injection are a relatively new segment of the pipeline industry. An affiliate of the Shell Oil Company has participated in two major pipelines for this service. The…
Recent development in complex network theory has boosted the exploration of topological properties of various natural and man-made complex systems. Refinery system is a typical complex system in process industry. However, only plant at equipment…
According to operation bottlenecks of tank farm, this paper discusses statistical risk simulator program that models the tank farm operation of refinery and covers a ship delay, lifting schedules, unit stream factor, maintenance activities, movement…
The automatic execution of underwater tasks like cleaning, inspecting, cutting and welding at production platforms or gas and oil pipelines requires manipulators with sophisticated control systems. Flexibility and adaptive behaviour are basic…
Natural gas transmission lines transport large quantities of natural gas across long distances. The analysis of these pipelines is very complex and the day-to-day operations leave little time for optimization. This paper details techniques that can…

With the rapid growth of the economy, air pollution becomes increasingly serious and environment protection has attracted more attention. It is a fact that ships produce enormous air pollution emissions with high energy consumption and research has…
Remote controlled pipeline block valves in high consequence areas require an extremely reliable installation in order to ensure line blockage and isolation. The Department of Transportation (DOT) defines high consequence areas (HCAs) as commercially…
The object of investigation is Central Station of oil accumulation (CSA-2) of Urengoi oil, gas and condensate deposit (OGCD) designed for accumulating and preparing for transportation oil and passing gas of oil edges as well as for transport, storage…
Heuristic methods are specially well suited to solve combinatorial problems. One of these problems is the distribution of petroleum products through oil pipelines networks. In this paper the problem is stated and solved using a multiobjective and…
The application of a programmable logic controller (PLC) for automation of petroleum product terminal deliveries is described. The basic philosophy of the automation is discussed, and subsystems required to achieve the desired level of automation are…

Floating Production Storage and Off-loading facilities (called FPSO in this paper) have become in a recent past a key-player in the recovery of Oil & Gas from deep sea wells. This paper intends to describe the engineering design drivers specifically…
The operating costs of a large-scale water seal oil cavern are a good deal of expenses. Water curtain can achieve a reasonable distribution of water seepage field to reduce the water inflow into the cavern by optimizing the arrangement of water…
A multi-stage interrelated discrete system (MIDS) is defined. By modelling this kind of system and giving out human expertise rules, a novel concept of synthetic knowledge is put forward. Then, a new heuristic node-path intelligent search method is…
In recent years, due to petroleum price going-up and the increasing interest of wholesale wheeling alternatives open to third-party generations as wind power etc., the problems about power system instability grow into a serious matter. For making…
