During 2017-2018 period, APROXAR, together with a software company, has succeeded in developing a specific application to operate based on Autodesk, and, thus, meet the company’s needs according to its way of working, developed over time.

The application has succeeded in merging different activities done in the Production Area between Technical Department and Process Department, with the aim of optimizing time and tasks to execute.

The work starts to be developed from an Excel spreadsheet in which, through different links among physical properties of fluids, pipe size to be used, flow velocity limits in different fluids, etc., the full list of lines to be used in the P&ID are designed. That information is collected by AutoCad (taking each line all the properties assigned) when the P&ID is made.

Once the P&ID is finished, the link between AutoCad and Excel follows, to extract, in previously designed spreadsheets by APROXAR on the latter, all specifications of different elements of resent lines in the P&ID (ball, globe, needle, safety, bellows, etc, valves-, steam traps, orifice plates, viewfinders, transmitters (either electric or not), retentions, etc.), which are delivered to the client in individual files, with a view to be able to be as practical as possible when sending documents to suppliers which will have to quote them.

The advantage of counting on this link between AutoCad and Excel is that, should any changes be made in the P&ID, they are shown automatically in all files and linked documents, i.e., specifications and calculations are updated without the need to be made by hand or in duplicate. On the other hand, with intelligence powered applications, all elements from P&ID are guaranteed to be found in a specification unerringly, and without the need of manually checking and adding, and the consequent human error elimination.

Document Management System and Intranet

During 2018’s period, APROXAR, together with a software company, has succeeded to develop a specific application, based on the company’s needs and the ways of working that this company has been developing throughout the years.

Such application has succeeded to merge various areas like: Commercialization, Production, Quality, Purchases, Administration, and Human Resources, with the main aim of optimizing time and task to execute, thus, allowing to reduce cost, simplify documenting and avoid duplication errors.

It starts from the budget/offer generation for a specific work (external/internal), which, once awarded by the client (or approved its execution in case of internal ones), it is authorized on the Intranet and documents such as Work Schedule, Master Lists of Documents to Deliver, Work Planning, Hour Distribution for every single area bound to intervene  in each project, etc.,as well as all corresponding reminder notices such as corresponding billing and collection dates, the delivery of customer satisfaction, the end-of-the-project message, etc., start to generate automatically as well as associated rates are generated, which reach completion as long as associated information is loaded during project execution.

The application also has a development that enables to track the evolution of projects and company’s goals, as well as the stated policy and risks to be faced, resulting in a tool for the Directory to make decisions taking into consideration real-time rates.

Sustainability in Effluent Handling in Biodiesel Units

Through the implementation of an effluent concentration system integrated to a methanol recovery system, the steam consumption has been successfully reduced, being this the equivalent to each of the systems mentioned above separately.

That saving, associated with concentrate handling which is sent to glycerin treatment for its recovery, and added to steams condensation, producing hot water of quality (without the need to use a condenser with tower water, and/or multistage systems), makes the system simple and reliable.

The system regulates itself according to the amount of wash water used in the process.

The water that is not re used in the wash stage is utilized in either caustic soda dilution of the pretreatment stage, or in the linter fluidization at the exit of the centrifugal separator of pretreatment.

To sum up, the system contributes to reduce the water footprint and the carbon footprint in a unit with aqueous effluent in general, and in case of the biodiesel units, through integration, it allows to lead to zero effluent.

Environmental impact mitigation per ton of biodiesel (compared to a two-stage system)

Energy savings:

  • 35-50 Kg of steam
  • 0,24 m3 of water treated to replenish in cooling towers
  • 3,2 Kwh of electric power
  • 6,4 lts. of effluents to dispose
  • 9,5 a 12,5 Kg of CO2 (without considering the decrease associated to electric power saving – it depends on its source of generation-)
