The minimum injection capacity of each pump should be 1 LPH or less and maximum injection capacity of pump should not be less than 10 LHP. 2(Two) nos. injection pumps within the skid, of which one working and one stand by, and should have provision to work simultaneously, if required. * Injection Pump: Simplex Plunger type reciprocating pump with adjustable stroke - Conforming to API 675. - Minimum operating capacity – 1 Ltr/Hr or less - Maximum operating capacity- 10 Ltrs. /Hr. or more - Maximum operating pressure- 100 Kg/Cm2 - Operating Range- 0-100 Kg/Cm2 - Temperature- 5 To 50 Degree Centigrade. - Pump should be able to inject chemical of viscosity in the range 800 – 1000 cP at 25 degree centigrade. All electrical equipment/Motor should be suitable for 230V/415V + 5%, 50 Hz + 3% AC. Equipment should be Flameproof and have CCE approval for use in Hazardous Area ZONE-I, Gas group IIA & IIB. * Mass Flow Meter: - Flow Range 0- 20 LPH & Type - Coriolis - Accuracy ± 0.5 % - Repeatability ± 0.05 % - Body SS304, Wetted parts SS316L - Displays the rate of injection, total volume injected, density and temperature - Meter has available output signals for user 4-20 ma - Weather proof & flame proof - Calibrated unit LPH (Litres Per Hour) * Control Panel: The system shall be provided with a dedicated LCP panel (EX-d Panel). 1. The panel should be suitable for use in hazardous areas and conform to Class 1, Zone 1, Div. 1, Gr. B, C, D. It should have Ingress Protection rating of IP65 or better. 2. The panel shall be made of Copper free aluminium (less than 0.4%) with hinged bolted cover. The panel body shall have aluminium lacquer paint finish standard suitable for installation in hazardous areas mentioned above. It shall have a minimum of 7" HMI display unit with suitable tempered soda lime glass window cut-out on panel to be provided for local monitoring, display of parameters such as Flow rate, Temperature etc. for operator interface. 3. To meet the functional requirements, the party shall provide necessary electrical and control equipments (PLC and relay logic) and these equipments shall be accommodated inside the local control panel. The bidder shall provide an indicative GAD for the panel along with their own list of hardware control components along with their bid. 4. PLC shall be single non redundant with inbuilt I/O and provision for expanding the I/O with suitable I/O cards. PLC shall be based on Compactlogix series processor or equivalent with diagnostic feature and capability to interface with remote RTU over Modbus TCP/IP for remote and local operation. Provision for ESD shall have to be incorporated in the PLC. For Remote/Local operation selection, necessary hardware shall be available in the panel. PLC shall have provision for PID control algorithm and ratio control algorithm to meet the objectives of the system. The bidder shall ensure that the PLC and related instruments work in the field conditions (such as high temperature) as mentioned above. 5. The bidder shall supply necessary safety Instrumentation systems to meet the functionality. 6. Development of control logics to meet the functionality shall be the responsibility of the bidder. 7. The panel and all other instruments and accessories shall be suitable for installation in hazardous area as mentioned in point No. 1. Necessary certifications in this regard to be attached along with the bid. * PLC programming for injection to be done in Litres per hour (LPH) * Hoses to be supplied with each skid up to the injection point on the Main Line Pipe Section. 1. Suction Hose: 1(one) No., 2'' x 10 M long with camlock fittings rated to 10 kg/cm2 (for connection from Tote having 2'' Male NPT to Skid) The hose shall be suitable for connecting with suction of feed/ booster pump at one end and DRA totes at other end. 2. Discharge Hose: 1(one) No., 10 M long discharge hose 1'' with swivel ends, rated to 130 kg/cm2 (For connection of injection pump outlet to the pipeline). The Hose shall be suitable for connecting with outlet of injection pump at one end and with pipeline injection point at other end. OIL will arrange for making ½” tapping on the carrier pipeline and fitting of 2” full conduit Ball Valve for injection of DRA Chemical. All necessary pipe fittings of 600 class rating required for connecting 1” hose/piping with 2”(50mm) ball valve flange including the 600 class Non Return Valve (This NRV to be fitted in between the Injection hose and injection valve will be in addition to the skid check valve) shall be in the scope of the skid supplier. 3.
