In most biochemical analyses, a flow-through heating arrangement is needed to reduce the reaction time or maintain a constant temperature. A rectangular reactor is described that is constructed of aluminium, is hollow inside and is filled with silicone oil. The glass coil through which the solution flows is immersed in the silicone oil. The heater, a Peltier-effect heat pump, on one side and th...

We demonstrate a nanophotonic sensor for real-time monitoring of fluid flows. The sensor is based on a silicon photonic crystal cavity with a well aligned micro fluidic channel for fluid-injection. The simulated resonant wavelength shift of the sensor with residual oil in holes is 9.0 nm, and the observed experimental shift under the same condition is 10.0 nm. An alternating fluid delivery is a...

This paper presents an economic study of a novel thermal fry-drying technology which transforms sewage sludge and recycled cooking oil (RCO) into a solid fuel. The process is shown to have significant potential advantage in terms of capital costs (by factors of several times) and comparable operating costs. Three potential variants of the process have been simulated and costed in terms of both ...

94 Production from heavy-oil fields in the UK continental shelf (UKCS) has become possible over the past 10 years. Despite substantial reserves in the UKCS of crudes with gravitiy of 20°API and lower, most of the activity has been exploration and appraisal drilling. The main reason for restricted activity has been high uncertainty of reservoir and fluid properties. A method was developed to fin...

Petrochemical industry is one of the key industry areas where Internet of Things (IoTs) and big data analytics could be widely applied to support smarter production and maintenance. In oil and gas exploitation, sucker-rod pumping systems are used in approximately 90 percent of artificially lifted wells. An automatic pipeline is crucial for real-time condition monitoring and fault detection of t...

Several studies have shown that the satisfactory oil well operations with sucker-rod pumps is attributed to the techniques and methods which are able to control the performance of the well. However, the presence of uncertainties in the sucker-rod dynamical models or parameter variations may jeopardize the desired performance of the control system and the rod pump system productivity. These para...

Pumps are often used in both industrial applications and mobile hydraulic machinery. In variable displacement pumps, the flow rate is dictated by the system requirements. The electro-hydraulic pump is a new integrated product, which comprise the combination of a pump and motor as a unit replacing the traditional connection with a shaft coupling. The pump is actuated without a rotating shaft uti...

This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...

Oil sand pumps are widely used in the mining industry for the delivery of mixtures of abrasive solids and liquids. Because they operate under highly adverse conditions, these pumps usually experience significant wear. Consequently, equipment owners are quite often forced to invest substantially in system maintenance to avoid unscheduled downtime. In this study, an approach combining relevance v...

Received an expression criterion efficiency taking into account stages extraction and repair well, as ratio volume extracted to consumed energy during cycle analysis processes. Mathematical system: asynchronous motor - pump hydraulic network is implemented in simulation pro...
