Work description | «Developement of feasibility study and Basic engineering design of the option selected for increase of market products output of propane-butane recovery unit UPPBS-3 (the 1st, 2nf and 5th line)» |
Types of works performed | Development of Basic engineering design (incl. conduction of feasibility study) |
Year | 2017 |
General data
At Unitary Subsidiary Enterprise Shurtanneftegaz, five UPPBS-3 units operate; they are intended for processing of gas of Shurtanskaya group fields and production of liquefied petroleum gas and heavy hydrocarbons fractions. Unit of the 1st line has been implemented based on LENNIIHIMMASH design. Due to the changed operation conditions, the units do not ensure the specified market products output. Feasibility study has been carried out in order to select an optimal option of unit operation efficiency increase, and hence, hydrocarbons C3-4 recovery rate.
Work results
Priority actions, aimed at unit operation improvement, have been proposed, they comprised methanol injection package for avoiding of hydrate formation and ensuring of trouble-free operation of the units without unscheduled shutdowns.
When conducting feasibility study, the work was carried out in two directions:
For the option approved by the Customer development and approval of base case process schemes and development of basic engineering design of upgrade of the existing UPPBS-3 units of the 1st, 2nd, 5th lines were carried out.
