1. LLC LUKOIL-NNOS

In February 2017, Basic design of Sweetening unit (treatment of 18,6 m3/h LPG from COS and mercaptans) being a part of Oil Residues processing complex on the basis of DEMERUS LPG technology with heterogeneous KSM-X catalyst was issued. Proposed technology involves joint purification of propane-propylene and butane-butylene fractions. Requirements for the residual content of carbonyl sulphide in PPF – no more than 6 ppm, total sulfur in BBF – not more than 10.0 ppm. Start-up of sweetening block – 2020.

2. JSC “Gazpromneft-Moscow Refinery”

In June 2013, Basic design of LPG sweetening block (33.3 m3/h) at Section 100 of Atmospheric-vacuum distillation unit was issued. It is based on DEMERUS LPG technology with heterogeneous KSM-X catalyst. Proposed technology implies joint sweetening of propane, butane and pentane fractions. Sweetening unit start-up – 2017-2018.

3. JSC “Tomskneftekhim” (SIBUR group)

In September 2016, Basic design for the Block of chemically polluted wastewater (75 m3/h) treatment  from sulfide sulfur was issued. The process is based on LOCOS technology with heterogeneous KSM-X catalyst. Treated feed is chemically polluted wastewater containing 2500 mg/l (0.25 wt.%) of sulfides (calculated as H2S). Besides sulfides chemically polluted waste waters also contain toluene, ethanol, phenol, formaldehyde, suspended solids. Unit start-up – 2017-2018.

4. JSC “Rosneft – Syzran Refinery”

In November 2010, Basic design of unit for sweetening of saturated (18.4 m3/h) and unsaturated (33.2 m3/h) hydrocarbon feed from GFU was issued. It is based on DEMERUS LPG technology with heterogeneous KSM-X catalyst. Separated butane-butylene fraction with total sulfur content not higher than 10.0 ppmw is used for MTBE synthesis. Saturated butane fraction with total sulfur content not higher than 10.0 ppmw is supplied to alkylation block. Sweetening unit start-up – 2020.

5. LLC “Rosneft-Tuapse Refinery”

In October 2014, Basic design of LPG sweetening unit (33.5 m3/h) at Section 5000 of “Flexicoking” Plant was issued. It is based on DEMERUS LPG technology with heterogeneous KSM-X catalyst. Proposed technology implies joint sweetening of propane-propylene and butane-butylene fractions. Requirements for residual hydrogen sulfide and mercaptan sulfur content – sum of both must not exceed 130 ppmw. Sweetening unit start-up – 2020.

6. JSC “Bashneft”

In April 2015, Basic design of LPG desulfurization unit (removal of carbonyl sulfide and mercaptans) (53.0 m3/h) at delayed coking unit DCU-2000 was issued. It is based on DEMERUS LPG & DEMERUS LPG + COS technologies with heterogeneous KSM-X catalyst. Proposed technology implies joint sweetening of propane-propylene and butane-butylene fractions. Requirements for residual carbonyl sulfide content – not more than 10 ppmw, mercaptan sulfur – not more than 5.0 ppmw, total sulfur – not more than 10.0 ppmw. Sweetening unit start-up – 2020.
