2 INTRODUCTION Today s world is demanding better condition in their way of life, and the demand of better services such as GAS, that s why our enterprise is interested in offering a new way to deliver Gas service to an entire community or town between 500 to more than 2000 subscriber among households, commercial and industries as well. Our proposal is safe, economic and ensures complete satisfaction to the end user TECHNICAL DESCRIPTION OF THE MOBILE GAS DES-COMPRESSING GAS UNIT The mobile virtual Gas Station is an Assembly of pipes, valves and equipment in order to receive 3,500 PSI pressure of gas storage tanks and adjust them to deliver the volume in M3/h and pressure that the client requests. Mobile virtual Gas Station design varies according to the technical requirements of customer. Modular design framed in steel and dimensions bars allowed on any type of trailer to safely send it to a working destination It supports all types of climatic conditions and can operate outdoors The volumes of gas according to the design range from 50 M3/h up to 2000 m3/h, the pressure (PSI or bar) is required by the client and under the API and ASME international safety standards. 1 Terms and scope Mobile virtual Gas Station meets the following technical - operational requirements RANGE Implementation of the basic engineering design and installation Criteria for selection of computers for GPRS Data transmission Pressures and working temperatures maximum and minimum for each of the components of the station. Configuration and control of heating equipment Configuration of the security scheme The station delivered design Security system in case of high pressure Compliance with normative references Operating and training Shipment of all elements for external and internal installation Engineering supervision during the entire project Test and trials to ensure quality of the project CUMPLY

3 2. Operation Conditions 2.1 ENTRY The des-compressor station unit is designed to receive the coming CNG modules storage under the following conditions: Income Max pressure of PSI Minimum working pressure 125 PSI Maximum temperature: 49 C Low temperature: 2 C The connections shall be flanged and sealed with gaskets espiro metal allowing a seal in the totality of the structure of the virtual station 2.2 OUTPUT Temperature output minimum: Maximum output temperature: Minimum of volume output Maximum volume output Pressure Out Put 7.3 C 40 C 50 M3/h 2000 M3/h 30 to 60 PSI The station is designed to decompress the gas coming from the storage modules CNG at a pressure of between 4.1 bar and 5.5 bar and to provide maximum flow minimum inlet pressure conditions. Maximum flow rate: Des-compressor station is able to supply the following values of flow rate at standard conditions up to 2000 m3/h. Installed equipment are equipped with feedback, allowing self-adjustment, delivering a flow and constant pressure, according to the requirements requested by the client 3. Processes included in the offer 3.1 FILTRATION The des-compressor station is equip with a filter system for the retention of moisture and solid particles, the filter designed has relief valves system that allows through eviction of moisture maintenance without having to disassemble the filter unit. The filters have efficiency for coalescence of 99.5% with a greater than 99% particle retention design. Two manometers of pressure on each end of the filter system shall be installed to determine differences in pressure and detect blockages by contamination on the filters. Changing the filter is quick and does not require the dismantling of any of the parts of the station, requires only the removal of the top cover and remove the used filter.

4 3.2 HEATING In order to prevent freezing of regulators due to compression of the gas, included the installation of a heater that will function heating the CNG in the stage of regulation of 4 C to 40 C and the CNG flow through the entire station entrance Offered heater uses the same gas as fuel, which ensures a greater margin of safety of work, autonomy and independence of installations providing greater security in operation. 3.3 REGULATION OF HIGH FIRST STAGE The first stage of pressure will be handled by High des-compressor units attached to the station, that will aloud the Station with the amount of working gas to meet the demand required. At all times the CNG is subject to heater that will allow a working temperature of 40 C to 32 C preventing freezing by decompression. 3.4 REGULATION OF HALF SECOND STAGE Axial controller has locking system by high pressure and low pressure with the following characteristics Type of connection: flanged ANSI 150 Includes: Locking mechanism and pressure switch for high pressure, with pressures according to spring It applies under the following conditions: Normal conditions: Normal income: 150 PSI Mínimum income: 80 PSI Exit pressure: 25 to 60 PSI P's shot blocking high: 250 PSI Maximum flow conditions: 2,000 m3/h 3.5 SECURITY SYSTEMS The station will feature the following safety systems Relief valves pneumatic performance of flow control ANSI 300 in the high-pressure phase 3.6 MEASUREMENT SYSTEMS Rotary meter model FMR G100 brand FMG, ANSI 150, 3 "in diameter, with low frequency pulse output 3.7 INSTRUMENTATION The station has local direct-reading instruments 1. Gauges: To operate outdoors under the fulfillment of the ASME B Ground Connector 4. PAINT AND PROTECTION PREPARATION AND APPLICATION The mobile Virtual Gas station has three coats of paint polyurethane for the sealing of steel with external elements

5 Polyurethane has two components that need to mix well and leave between fifteen to thirty minutes, before its application. After using the component B (catalyst), it needs to close well container to prevent the entry of air and moisture. The first layer with two-component anticorrosive paints After the first application, is expected 24 hours, never more than 36, to apply the second. Proceed in the same way on successive applications. This allows good adhesion between hands. MODELS MOBILE DESCOMPRESSOR UNIT FROM 500 TO 2000 M3/H GAS STORAGE UNITS

6 All stations are compact, built on a steel frame for your protection, handling with elevator or crane and safe transport in a truck trailer. It can be installed in any room and outdoors. It supports all types of weather conditions EXTERNAL GAS NETWORK Pipes and accessories for conduction of gaseous fuels are obtained from medium density (MDPE) grade PE2406 or PE80 and high density (HDPE) polyethylene grade PE4710 or PE100 for up to 145 PSI working pressure. Polyethylene accessories required for the connection of pipes such as: unions, tees, caps, reductions, saddles, transitions among others are manufactured from the same resins and the design confers greater resistance to the internal pressure, these products possess equal or superior characteristics for external use MOBILE GAS DESCOMPRESOR UNIT TECHNICAL CHARACTERISTICS Product name: Mobile Gas des-compressor unit Product description: The Mobile Gas des-compressor unit is designed to supply gas to the community of a City municipality and/or the industry, according to the requested pressure and flow requirements, is built into a steel frame that provides security and versatility for transport, according to the requirement of the client has the ability to deliver a volume of gas from 50 M 3/h up to 2000 M3/h, in a range of output from 25 PSI to 60 PSI pressure.
