Electrical Power

The Electrical power requirement for the Membrane Nitrogen unit is:

Local Control Panel : ~ 0.5 kW - 110V – 50 Hz – 1 ph Electrical Heater/Thyristor : ~ 90 kW - 415V – 50 Hz – 3 ph

II Basic design is 9.7 barg inlet pressure. When feed air pressure drops below minimum of 9.7 barg oxygen level will rise slightly at required outlet capacity. If feed air pressure rises above 9.7 barg more feed air is required to maintain required outlet capacity. III Basic design is max. 60°C Feed Air temperature. If the feed air temperature increases over 60ºC for a longer period the impurity (residual Oxygen) of the product gas may raise slightly. If required, the capacity has to be reduced to achieve the specified purity (max. O2 content).

6. DEVIATIONS AND EXCEPTIONS

This quotation is based on the project specifications provided with the MR. Any deviations / clarifications to the project specifications are stated in the Deviation List, attached to our Technical Proposal. The Deviations are based on Vendors experience with similar projects / applications and result in the most reliable, lowest maintenance and cost effective design. Please find enclosed a detailed clarification/deviation list. General remarks: 001 All reference project specifications and company specifications /standards,

referenced within the project specifications which are provided during bidding phase, but not in our possession, are excluded from our scope of supply.

002 Both inlet piping (upstream membranes) as outlet piping (downstream membranes) are made of carbon steel, since feed air is utility air which contains oil vapor.

003 Cirmac is constantly working with suppliers to ensure that they are aware of the UN terms of fair trading and our Business code of practice. We have implemented a supply chain quality process that we believe will ensure the quality, safety and reliability of the equipment we supply, including raw materials and therefore do not exclude any countries from our material sourcing.

004 A drip pan is not included, because we believe its not required since the feed air is dried (coming from an instrument air dryer)

005 A performance test is excluded from our scope of supply. 006 Selected Sub-Vendors as per section 5 of this Technical Proposal. Other sub-

vendors can be quoted upon special request. 007 ON/OFF sequence valves are not considered as Control valves. 008 I.A. connection and tubing for ON/OFF valve actuators will be ¼” OD / NPT 009 No dedicated valve control panel, I.A. filter reducer and/or ‘local air buffer vessel’

are foreseen for each ON/OFF valve and/or control valve. Only one common I.A. filter reducers is foreseen towards a common I.A. header for distribution to each ON/OFF valve and/or control valve.

010 Split-body (bolted), floating type ball valves (full bore), ANSI 150lbs, PTFE seat, fire safe (API-607) are foreseen for ON/OFF sequence valves, manual isolation and instrument root valves.
