Gasoline In-Line Blending
LUDAN successfully completed a turn key project (complete design, construction, commissioning) for Gasoline In line Blending system. The Customer finally got a continuous installation for mixing different components streams in order to obtain a final product of closely defined proportions. The implemented technology is considered more economic than batch blending method. It saves money by blending faster, requiring less manpower and storage facilities and by reducing the quality giveaway.

New Central Control Room
The control and information system includes a central control center where the refinery personnel monitor and control the site units through field equipment and instruments. Each unit contains hundreds of monitored and controlled input/output instruments. The information system collects and stores all the site data, and enable refinery employees to use the data on a real time basis as well as through a set of dedicated reports. LUDAN scope of work was: study the existing installation (control, wiring), identify cables and their marking, Complete implementation in the new control system and install it alongside with the old one, Switch-over without stopping production - disconnect the cable from the old system and connect to the new, repeating cable after cable. The big advantage: a gradual transition and an immediate identification of wiring errors and malfunctions, transition during shutdown- transition the rest of the old system to the new system.

Design of Delayed Coker Unit (DCU), Gas Absorption and Fractionation (GAF)
The DCU processes mostly the vacuum residue from the VDU of the crude unit but also residual streams from FCC, heavy aromatics from Solvent Deasphalting GAF purpose is to stabilize gasoline and prepare it for storage and further processing in gasoline hydro-fining units. Light gaseous hydrocarbons dissolved in feed are absorbed in a stabilized recycle stream followed by separation of the LPG and stabilized gasoline. For a DCU 200,000 tones LUDAN has developed the Basic Design Package for a DCU of 200000 t/year feed capacity, including: process calculation and process specification; plant layout; civil design; electrical design; instrumentation specification; process control philosophy; CAPEX estimation.

Design of Kerosine/Diesel Hydrofining Unit (DHU)
Kerosine/Diesel Hydrofining Unit (K/DHU) is able to process various feeds (heavy naphtha, kerosine, gas oil) from different refinery units. The unit capacity is 200.000 ton/year processed feed.The K/DHU processes mainly the kerosine and/or gas oil from Crude Distillation Unit (CDU), Delayed Cocker (DCU), Fluid Catalytic Cracking Unit (FCCU). The unit can change operating modes according to commercial demand in order to produce jetfuel (kerosine) or diesel Euro 5/6. LUDAN has developed the Basic Design Package including: process calculation and process specification; plant layout; civil design; electrical design; instrumentation specification; process control philosophy; CAPEX estimation.

Design of Sulfur Recovery Unit
The sulfur recovery unit concerns the gas treatment for H2S removal in a SulFerox® Unit at low pressure, near to atmospheric. This type of unit is simple and reliable. The SulFerox process requires the gas without liquid hydrocarbons and dust. This project is based on a 99.9% + overall sulfur recovery; in this case, H2S content in treated gas will be less than 10 ppmv. LUDAN has developed the Basic Design Package for Sulfur Recovery Plant of 3000 kg/year sulfur including: process calculation and process specification; plant layout; civil design; electrical design; instrumentation specification; process control philosophy; CAPEX estimation.

Lube Base Oil Production from VGO Fractions
The Customer has considered the possibility of production of industrial base oils from a type of local naphthenic crude oil. The Base Case foresees construction of the new production line using existing infrastructure (existing crude/vacuum distillation units CDU/VDU, tank farm and utility systems). LUDAN scope: assessment of CAPEX and OPEX requirements according to four possible configurations; assessment of an additional project module – construction of a Dewaxing unit; recommendations on the optimal project configuration for base oils production; recommendations on optimal capacity of all new units; confirmation of final product specifications in each project configuration; preparation of client input data and tender documentation for basic engineering.
