All used electrical equipment of the shop, including electric lighting, is made in an explosion-proof design. The project envisages measures to minimize the level of hazardous production factors.
The automated control system of the shop includes a system of emergency protection and automation of the following systems:
- water circulation
- circulation of the placenta in the extractor
- circulation of gasoline condensate
- control of solvent level in underground tanks
- "zero" runoff system
- evaporation of the solvent in the toaster
Levels in the devices, local temperature and steam, vacuum depth are measured by safe Krohne level gauges, and Endress + Hauser pressure sensors.
The systems use Camozzi pneumatic equipment, YTC position transmitters, Pepperl + Fuchs level alarms.
Additionally, all pumps are equipped with emergency protection implemented on the basis of vibration sensors Endress + Hauser.
The redler of loading of meal in the toaster is equipped with sensors of rotation on a tension section and on a known asterisk near a reducer. Camozzi sealed gate valves are used to organize safe operating conditions.
Sensors located in the shop have an explosion protection category ATEX Ex ia IIG 5-6TC. Such sensors are connected via Pepperl + Fuchs KFD series spark protection barriers, which meet international requirements in accordance with the ATEX and Namur directives. Control of pneumatic valve solenoids is also implemented through spark barriers that limit the current in the line to 100 mA.
The Siemens controller and discrete and analog I / O modules are used to implement the operation of all process equipment.
The visualization program is based on Siemens WinCC 7.4 software
The program implements the control of all actuators and data trend of all analog quantities.
Starting and regulating equipment of electric motors of direct start of the Lovato company.
The main delivery set also includes a lighting system. Only respective safety transit lamps are applied.
For the implementation of the cable system project, wire trays DKS, power and control cables of leading manufacturers are used.
The scope of delivery also includes: Socomec uninterruptible power supply to provide emergency lighting in the shop.
Extraction takes place under the control of specialized systems that allow you to quickly track possible leaks. In case of unforeseen circumstances, to ensure emergency ventilation, the vegetable oil extraction plant is equipped with a system with safety valves that open if unforeseen circumstances lead to an increase in pressure.
