ARQUIMEDES SCREW PUMP METALLIC PROTOTYPE (ALUMINIUM + STAINLESS STEEL)

Once the new parts were made we could simulate working conditions, actual adjustmen between parts and ready a more robust prototype than the previous one whose body was completely made of sintered powders of nylon.      The test bench confirmed the first tests results and helped us to know better the limits of each [...]

STAINLESS STEEL ARQUIMEDES’ SCREW

Once we've verified the design of the screw, we're starting its production in stainless steel. Due to its geometry and its perfect fitting with the sealing disc it's the most complicated part of the pump. Nevertheless we're confident of achieving the goal!. After quite a few attempts and difficult adjustment and setting of various machine [...]

CONSTRUCTION OF THE FIRST PROTOTYPE OF THE PUMP

Once the idea was developed, to build a skimmer equipped with a Archimedes screw pump but able to separate part of the recovered water, we start manufacturing of the prototype. Although our final aim is to manufacture a robust pump capable of working with any type of fluid, and being stainless steel the material that [...]

LET’S START!

Analyzing performance and design of the available pumps we are inclined to use screw pumps in our aim to reduce water content in the skimmer. Its geometry and the way in which power transmission takes place makes us think that they are the most suitable to work together with a centrifugal separator.   Now is [...]

RECOVERED OIL PUMPING

In order to find a solution to the problem of the huge amount of water recovered together with the spilled hydrocarbons we need to know how these are pumped from the skimmers, because their knowledge will help us to find the best way to integrate the industrial separation methods presented in the previous post. Once [...]

INDUSTRIAL SEPARATION TECHNIQUES

In this post we will present different methods of oil/water separation and will analyze feasibility of using them to improve the efficiency of skimmers and pumping units. Gravity Differential Separation: The oldest and more extended separation method. It’s usually the first step in the treatment of oily water. Ruled by the Stokes' law is based [...]

A NEW ROUTE OPENING

The goal has been focused: We need to increase the efficiency of skimmers and improve the energy balance of decontamination operations. We could analyze step by step response operations up to final treatment trying to adopt better techniques and integrating low consumption motorizations, we will, but there is a job we can do before and [...]

SOLUTIONS TO THE PROBLEM OF MECHANICAL RECOVERY EFFICIENCY

As mentioned in previous post, the low efficiency of mechanical recovery devices causes high additional costs of decontamination and purification. Among the factors that impact on mechanical recovery efficiency we have cited the weather conditions and the type of skimmer. Improving weather is not something that is in our hands but improve existing skimmers performance [...]

ENERGY BALANCE OF MECHANICAL RECOVERY

Oil spill recovery operations have a huge energy cost as well as causing a secondary pollution caused by the use of polluting engines. Besides the use of antediluvian technologies, the largest contribution to energy consumption growth during the recovery operations is caused by the decrease in the efficiency of skimmers, or what is the same, [...]

THE PROBLEM OF MECHANICAL RECOVERY EFFICIENCY (II)

Due to the limited efficiency of oil recovery systems in real conditions and in presence of waves the amount of water in the temporary tanks is too high.   Depending on the environment the negative consequences can be increased.   In an industrial environment the cost of treatment (separation / purification) of oil / fat [...]
