1.11.001 Inlet/Suction Scrubber

This Policy is completed and waiting Field Service, Engineering, and EHSS approval.

Purpose

The purpose of this procedure is to establish the minimum requirements for understanding the internal components of the Inlet/Scrubber vessel on Flogistix FX model units. The procedure applies to all Flogistix FX model units equipped with an Inlet/Scrubber vessel.

Procedure

This procedure applies to all Flogistix FX model units that are equipped with an Inlet/Scrubber vessel equipped with an internal blowcase that is currently in service in the Field, Test Loop, at a Repair Shop, or in Storage Yards.

The Inlet Vessel on FX model units, also called a Suction Scrubber, that Flogistix uses is designed with an internal Blowcase. It is one vessel but has two separated compartments like a vessel inside of a vessel.

This vessel is also equipped with an automatic dump valve controller to remove any fluids that come into the vessel.

The example below is a visible 3D model of the FX model Inlet vessel.

The purpose of the internal blowcase gives the ability to evacuate fluids from the vessel when running low inlet pressures, including when running in a vacuum.

The blowcase is pressurized using regulated gas from the discharge of the compressor.

The internal blowcase is located in the lower section of the inlet vessel.

As shown in the example below indicated by the arrows

How the Inlet Vessel works and the internal parts:

The Inlet nozzle is not centered in the vessel.

As the gas enters into the vessel it begins to swirl around the inside of the vessel.

As shown in the example below fluids flowing with the gas will begin to attach to the inside of the vessel wall.

Fluids that attached to side of the vessel wall will then run down the vessel wall to the bottom of the vessel.

The gas will then travel up through the center of the inlet vessel. In the center section of the vessel is a stainless steel mist extractor pad.

Any fluid traveling with the gas should collect in the mist extractor and then fall to the bottom of the vessel as droplets.

After the gas goes through the mist extractor pad the gas will then be in the upper chamber of the vessel.

In the upper chamber is the inlet gas filter.

The gas will then flow through the inlet filter from the outside of the filter into the center of the filter.

The gas then travels up and out of the inlet vessel from a smaller flange in the center of the top of the Vessel flange.

The inlet filter has a micron rating of 5 microns.

Inlet Vessel Blowcase

Fluid that has collected in the bottom of the inlet vessel will then need to go into the blowcase to be evacuated.

The blowcase uses regulated gas pressure supplied from the discharge of the compressor unit.

Fluid travels into the 2” external piping, then travels through a 2” check valve.

It then travels on and falls into the blowcase section of the inlet vessel.

In the normal operation mode with both vessel sections are equalized, the valves will be in the following positions.

When fluid has filled the blowcase, the pneumatic level controller will send pressure to the valves to activate the blowcase.

When activated by the Pneumatic Level controller to evacuate the fluids out of the blowcase the valves will be in the positions as shown in the example below

When fluid has been evacuated from the blowcase, the pneumatic level controller will stop sending pressure to the valves activating the blowcase.

The valves will then return back to normal operating positions.

To manually operate the dump controller, push the button on the controller as shown in the example below by the orange arrow

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.

EHSS - Responsible to assist in the implementation of this procedure and to review for effectiveness.

Employees, Contractors, Vendors, ETC. - Are responsible to follow the requirements outlined in this procedure and ask for assistance

Scope

This procedure applies to all Flogistix FX model Inlet/Scrubber vessels and are applicable to all Flogistix employees, contractors, and temporary employees.

Hazards

Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids, rotating equipment. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes.

Safety

All Personal Protective Equipment (PPE) for normal Field Mechanical duties apply for this procedure.

Four Gas Monitor, which is outlined in the Flogistix EHSS Manual, PPE Section 8, Procedure 8.3

This procedure applies to all units in service in the field, at a service shop, or in any storage yard.

Insure Flogistix personnel have proper safety certification or site orientation if required by the Flogistix Customer.

Insure Flogistix personnel adhere to all Customers safety practices.

Training

All employees shall be initially trained on the following topics:

• Employee Personal Protective Equipment (PPE)

• Lock Out Tag Out (LOTO) procedure according to Flogistix policy

• Emergency and First Aid procedures

• Methods and Observations that may be used to detect the presence or release of a hazardous chemicals or gas in the work place

• Basic LOGIX panel training

Tools & Equipment Required
