2.0 PROPOSAL SUMMARY

2.1 INTRODUCTION

Cameron offers this firm proposal for design, manufacture and supply of one (1) Amine Sweetening

Unit treating 20 MMSCFD gas for the Litoral Tabasco project.

Please note: The proposed system is strictly based on the AS-SOLD Amine System to

Dragados for the CA-A project. Any deviations, exceptions and clarifications in the CA-A

Amine System will also apply to this Amine System for the CB-A as well.

The system is designed to treat 20 MMSCFD (maximum) of feed gas total. Refer to Section 3.0 of this

proposal for a summary of process design conditions. The purpose of this introduction is to highlight

some of the main points of this proposal document.

Cameron has reviewed PEMEX design for the Amine sweetening system and has moved the pre-

filtration section of the lean amine upstream of the DEA Balance tank.

By placing the three equipments - Lean DEA Pre-filter, Lean DEA Activated filter and Lean DEA

Post filter upstream, the DEA balance tank can see a much cleaner lean amine and hence

minimize any settling of contaminants in the DEA Balance tank.

This design eliminates the use of the booster pumps GA-5404 A/R. By providing this configuration,

the overall design of the amine plant is simplified with less number of rotating equipment, valves,

instruments and associated piping.

Cameron has also designed the unit with one (1) DEA charcoal filter per train. Based on our

experience, single charcoal filter is required for this process with full bypass on the filter for

maintenance.

Cameron has designed a filter separator for the Liquid Gas Separator. The filter separator provides

better performance which will remove any unwanted particles and hydrocarbon liquid that comes

with the feed gas from the compressors.

Cameron has designed the unit for a maximum of 55°C feed gas temperature to the DEA

Contactor. The Amine reaction is an exothermal one so the higher temperature of the feed gas will

mean there is a lot of heat generated in the DEA Contactor which will make it impossible to meet

the required sweet gas specification. For the maximum operating case (90 kg/cm2 and 80°C),

there will be the need to install an air cooler upstream of the DEA Contactor and this will cool the

gas temperature down to max of 55°C before the DEA Contactor. Currently, Cameron has not

included the feed gas cooler in our scope of supply. Should this case be required, Cameron can

provide the additional cost for the air cooler.

Cameron’s experience in the design, fabrication and field support of Amine Conditioning Packages

extends several decades. We appreciate this opportunity to utilize this know-how in our current

proposal. The Cameron organization is ready to support the Dragados PEMEX Litoral Tabasco Project

Teams in whatever way possible to make this endeavor a success.

requirements of this Requested for Quotation with the EXCEPTIONS listed below.

Spec No. Title Rev. Rev. Date

85013-RM-H-002 Material Requisition A 10-11-12

Following is excluded from Cameron scope and shall be provided by Customer:

All consumables (oils, greases, fluids, products, etc.) for installation, commissioning, start-up and offshore acceptance tests as Cameron is not in a position to supply chemicals to the companies due to country regulations.

The first amine charge is by Customer as Cameron is not in a position to supply chemicals to the companies due to country regulations.

Process Design:

Cameron design considers the Feed gas maximum supply temperature of 55 oC instead of 100 oC. In order to achieve the outlet gas specification, there will be the need to cool the feed gas in a Feed Gas Cooler to a maximum of 55 oC before the DEA Contactor. The cooler is not included in Cameron’s scope of supply.

Cameron has deleted DEA Pump GA-5404 AB/R as the DEA Booster pump can be used to boost the lean amine pressure up to outlet of the DEA Surge Drum where the High Pressure Pump will supply the required pressure to DEA Contactor Tower.

Cameron has relocated the location of the Lean DEA Filter to upstream of the DEA Surge Drum. Based on our experience, this is the best location for the filters

5.0 TECHNOLOGY

5.1 GENERAL

Amine sweetening has been used for many years to remove Hydrogen Sulfide and Carbon Dioxide

which are often found in natural gas streams.

Cameron designs and manufactures a variety of gas sweetening systems, including amine systems.

Cameron designs can support several varieties of amine solvents, which remove the contaminants by

chemical reaction.

Gas sweetening with amine is a well-established process, which allows continuous plant operation

enabling simple and economic plant to be utilized. As per the client requirements, we have utilized

DEA Amine (30%) for this process.

The feed gas enters the vertical Contactor tower where the gas is counter-currently scrubbed by the

amine solution over a section of 20 valve trays to achieve the desired degree of H2S and CO2

removal per outlet specifications.

The performance of the contactor, in relation to the process requirements is determined by carefully

selecting the following parameters:

Height of trays

Valve tray type

Type of Amine/Solvent solution

Lean Amine acid gas loading

Amine circulation rate

After leaving the top of the packing, the gas passes through a demister, which serves to reduce amine

entrainment losses to a negligible level. The sweetened gas then leaves the contactor. The Acid gas-

rich amine solution leaves the Amine Contactor where it is to the amine flash drum after pressure

reduction to remove dissolved hydrocarbon from the rich amine. Flash gases are collected and mixed

to the Acid gas from the Amine Reflux drum where it is sent to the acid gas compressor. The rich

amine is then filtered in the Rich Amine Filter to remove solid particles from the amine solution.

After filtration, the amine is preheated in the Lean/Rich Amine Exchanger where the hot lean amine

exiting the Amine Regenerator is used to pre-heat the incoming cool rich amine to 99°C prior to it

being fed to the Amine Regenerator, under level and pressure control (controls the amine level in the

Amine Contactor).

Hot, rich amine from the Lean/Rich Exchanger then passes to the top of the trays of the Amine

Regenerator. The rich amine flows downwards where it is stripped of the majority of acid gases by


CLIENT REF.: N/A



contact with steam rising up through the trays. From the bottom of the trays, the amine is withdrawn

from a chimney tray to feed the Amine Reboiler. The Amine Reboiler operates at a temperature of

~124°C and is designed to produce sufficient steam to strip the acid gases from the rich amine in the

regenerator packing.

The reboiler is a horizontal vessel with heat exchanger that uses hot oil as the heating medium. The

regenerated amine and steam are returned to the regenerator where the hot lean amine flows via

gravity through the Lean/Rich Exchanger and the Amine Cooler before being pumped up to contactor

pressure by the Amine Circulation Pumps under flow control. The temperature leaving the Lean Amine

Cooler is controlled at 57°C, which is 6oC above the sour feed gas temperature to the Amine

Contactor.

Overhead vapor leaving the Regenerator is routed to the Amine Regenerator Overhead Cooler where

the water vapor is condensed and collected in the Amine Regen Reflux Drum. The condensed

overheads are pumped back to the top of the Regenerator via the Amine Regeneration Reflux Pumps.
