Acceptance and Storage

4 two-way railway racks ensure simultaneous unloading of 526 tank wagons:

2 two-way railway racks for black oil products discharge ensure the acceptance of 4 trains of 72 wagons each
1 one-way railway rack for discharge of light oil products ensure the acceptance of 2 trains of 72 wagons each
1 two-way railway rack for discharge of high-viscosity oil products ensures the acceptance of 2 trains of 47 wagons each

Given the fact that the Terminal handles a wide range of oil products, two main discharge methods are used during their unloading:

  • without heating: for light oil products;
  • with heating: for high-viscosity oil products.

For handling high-viscosity oil products, such as fuel oil and vacuum gasoil, the Terminal has three railway jetties. The discharge technology is based on the principle of group recirculation method for oil products heating. Each group consists of 6 rail tank cars, heat-exchange equipment, pumping equipment and a control system. The pumping and heat-exchange equipment is installed immediately within the area of a discharge jetty. The unloading process is automated and controlled from the discharge operator room. The thermal agent is a high-temperature medium – thermal oil.

This equipment configuration and the control system allow for unloading fuel oil for 4.5–5.0 hours in summer and for 8.0 in winter per unloaded unit train. At one of the jetties, an additional engineering solution has been implemented for upper washout of fuel oil, which allows for reducing the time of black oil fuel unloading.

The discharge of light oil products is performed using the conventional method via a common manifold using the dedicated pump group.

An important issue, when carrying out technological operations at the Terminal, is preserving the oil product quality. For this purpose, all jetties provide for the possibility to divide products of different quality and to discharge them through dedicated service pipelines without mixing with other products.

Oil Products Storage

The tank farm allows for storing 960,000 cu. m of oil products:

22 storage tanks for black oil products with a total rated capacity of 630,000 cu. m.
11 storage tanks for light oil products with a total rated capacity of 330,000 cu. m.

The storage tanks for black oil products have a heat insulation and are equipped with an external system for heating and maintenance of the set product temperature. The storage tanks for light oil products are equipped with pontoons to minimize the oil products evaporation and to reduce their release into the atmosphere. The service piping of tank farms allows for solving two important tasks: to ensure segregated storage of different batches of oil products and, when necessary, to modify the dedicated tank capacity for accumulation of specific tanker batches.
