– Single unit for continuous, simultaneous measurement of contaminants in H2 small, high 2O and CO2 natural gas streams for trade handover, tariff compliance and process monitoring

– ABB’s proven laser technology virtually eliminates false readings and provides fast response for reliable process control

– Designed for remote and hazardous locations, Sensi+ delivers superior performance and low cost of ownership

ABB’s Sensi+ analyzer offers a reliable new solution that simplifies and reduces pipeline operation and maintenance costs.

It enables safer, easier and more efficient pipeline monitoring and operation with a single device that

The device can analyze up to three contaminants (H2 minor, 2O major, CO2) accurately and in real time in any natural gas stream.

Its fast response also enables quick reaction to process disturbances, which can help reduce waste and methane emissions.

Reducing the risk and impact of natural gas contaminants often presents challenges for natural gas pipeline operators, the processing industry and natural gas utilities.

Description

• Overload protection – trip class 10A

• Phase loss sensitivity

• Disconnect function

• Temperature compensation from -25 … +50 °C

• Adjustable current setting for overload protection

• Suitable for three- and single-phase application

• Trip-free mechanism

• Clear switch position indication ON/OFF

Manual motor starters (also known

as motor protection circuit

breakers or manual motor

protectors) are electromechanical

protection devices for the main

circuit mainly used to switch

motors manually ON/OFF and

protect them fuseless against

short‑circuits, overloads and phase

failures. Fuseless protection with a

manual motor starter saves costs,

space and ensures a quick reaction

under short-circuit condition, by

switching off the motor within

milliseconds. Fuseless starter

combinations are setup together 

​with contactors.

Scope of supply

ABB S.p.A. (Italy), in cooperation with Lee Engineering &

Construction Co (Nigeria) and Franzisella S.p.A. (Italy), is

supplying a fully integrated solution for the WAGP (West

African Gas Pipeline) project in Nigeria.

The two WAGP Gas Compressor Stations in Utorogu and

Oben are based on the latest ABB MNS iS technology

installed into prefabricated E-houses.

The ABB MNS iS is the right solution to comply with the high

level of integration and compactness requested for the WAGP

Utorogu and Oben Gas Compressor Stations.

The ABB MNS iS Power and Motor Control Centers for the

WAGP project are fully integrated with the station DCS via

serial link (Profibus DP protocol) and are built in compliance

with Shell DEP standards.​

Plant description

Pipelines are the most efficient way to distribute gas and

cover big distances especially in location with critical

environmental conditions like deserts, glaciers, high

mountains. To keep pressure and temperature of gas at the

right level, Gas Compressor Stations are present and placed

at 10 to 150 Km intervals along the pipeline. The low voltage

MCC is one of the most important and critical component of

those compressor stations

MNS iS Design & Components

Switchboard Construction

MNS iS as part of the ABB Low Voltage Switchgear solution uses the well proven ABB MNS standard design aspects.

MNS aspects described in this section are fully applicable to MNS iS.

MNS system is a verified design in accordance with IEC61439-1/-2.

The consistent application of the modular principle both in electrical and mechanical design

as well as the use of standardized components allows its flexible and compact design.

Depending on operating and environmental conditions different design levels are offered.

Notable system advantages with regard to design aspects:

Compact, space-saving design

Easy project and detail engineering through standardised components

Verified design acc. IEC 61439-1/-2

Earthquake-, vibration- and shock-proof designs are available

Easy retrofitting without the need for switchgear de-energizing

Maintenance-free busbar construction

High operational reliability and availability

Optimum personal protection

INTRODUCTION

Instruction Manual Structure

The present manual provides information on installing, operating, troubleshooting the 364 pressure transmitter.

Every section of the present manual it is specifically dedicated to the specific phase of the transmitter

lifecycle starting from the receipt of the transmitter and its identification, passing to the installation,

to the electrical connections, to the configuration and to the troubleshooting and maintenance operations.​

General Safety Information

The “Safety” section provides an overview of the safety aspects to be observed for operation of the device.

The device has been constructed in accordance with the state of the art and is operationally safe.

It has been tested and left the factory in perfect working conditions.

The information in the manual, as well as the applicable documentation and certificates,

must be observed and followed in order to maintain this condition throughout the period of operation.

Full compliance with the general safety requirements must be observed during operation of the device.

In addition to the general information, the individual sections in the manual contain descriptions of processes or procedural instructions with specific safety information.

Only by observing all of the safety information you can reduce to the minimum the risk of hazards for personnel and/or environment.

These instructions are intended as an overview and do not contain detailed information on all available models or 

every conceivable event that may occur during setup, operation, and maintenance work.

For additional information, or in the event of specific problems not covered in detail by these operating instructions,

please contact the manufacturer. In addition, ABB declares that the contents of this manual are not part of any

prior or existing agreements, commitments, or legal relationships; nor are they intended to amend these.

All obligations of ABB arise from the conditions of the relevant sales agreement,

which also contains the solely binding warranty regulations in full.

These contractual warranty provisions are neither extended nor limited by the information provided in this manual

Wet and dust-laden atmospheres

The transmitter is dust and sand tight and protected

against immersion effects as defined by IEC 60529 (2001)

to IP 67 (IP 68 on request) or by NEMA Type 4X.

IP65 with Harting Han connector.

Aluminium and AISI housings as barrel version also comply

to IP 66 as defined by IEC 60529 (2001).

IP66W/IP67W/IP68W as standard for Inmetro certification.

Specification – performance
