Products

When using the technology of condensate stabilization by degassing, the choice of the number of stages depends on the content of low-boiling hydrocarbons in the condensate: the higher it is, the greater the number of stages required. Typically, this technology of the stabilization process is used in fields with a low condensate factor.

When using the condensate stabilization technology, the rectification method (most often carried out in 2 or 3 columns) makes it possible, in addition to stabilization gases and stable condensate, to obtain a propane-butane fraction (or propane and butane). In modern plants, a combination of separation and rectification processes is usually used, which makes it possible to increase the technological flexibility of the process and reduce energy costs.

Design features

The unit is mounted on an open site or can be a complete prefabricated unit, tested and adjusted to operating parameters. USK is a set of blocks of maximum prefabrication, supplied by rail, road and other modes of transport. The composition and execution of each specific installation is determined based on the requirements of the Customer.
