About us
We have been designing and manufacturing hydrocarbon processing plants for over 10 years, and we have rightfully earned a reputation as a reliable and trusted manufacturer to our customers. The uniqueness of our plants lies in their scalability - as processing volumes increase, our customers have the option to increase productivity by simply attaching individual units to an existing installation, without the need to place new stand-alone plants.
The safety of our installations is ensured by both the automated control system (ACS) and the fire extinguishing system, which are both optional features that can be installed at the customer's request. The ACS ensures that the production process is stopped when certain control values are exceeded.The installations are designed to allow for rapid reconfiguration and adaptation when switching to different qualitative parameters of the raw materials, allowing you to continue production in the event of interruptions to the supply of raw material from the main source, and not becoming dependent on a single source of raw materials.

The stability of our systems is ensured by a number of factors:
Thanks to the facilities that have already been put into operation, and based on feedback from customers, we are able to optimize the design of our equipment and make it as fault-tolerant as possible.
Duplication of the supply chain for zeolite catalysts: (The required quality and brand of catalysts can be supplied by several Russian suppliers simultaneously.)
The equipment is designed so that the regeneration of the catalysts takes place directly in the reactor and does not take more than 3 days.
Only Russian equipment, components and aggregates are used in the production process, which not only reduces maintenance costs but also significantly speeds up logistics when scheduled replacements are made.
MINI-REFINERY EQUIPMENT BLOCKS
RECTIFICATION UNIT
The rectification unit is designed to separate hydrocarbon raw materials into fractions with different boiling limits. The quality of the fractions at the output is determined by the requirements of the consumer. Flexible regulation of the rectification process allows you to obtain up to three fractions at the same time:
– the fraction from the beginning of boiling (NC) to 150-200 °C;
– fraction from 160 °C to 270-300 °C;
– fraction from 260 °C to the end of boiling (KK).
The accuracy of the separation of fractions depends on the quality characteristics of the raw materials, but in any case, the end of the fraction interval is separated with an accuracy of 1-2 degrees, and the beginning of the interval with an overlap of 5-10%, due to the peculiarities of the composition of hydrocarbon raw materials and the separation technology itself.
The resulting products of the rectification process are the raw materials for the isodeparaffination and isoriforming unit. In the process of rectification, C5+ hydrocarbon gases are formed (in an amount of up to 6% of the mass of raw materials), liquefied in a compressor unit to produce liquefied petroleum gas SPBT (propane-butane technical mixture), which is subsequently used to heat raw materials (using a fire furnace heating), which significantly reduces the cost of heating it.
Devices and equipment of the unit
