Success Case 1. CompressorsSuccess Case 1. Compressors

Equipment: 3 Compressors, Cooper Bessemer GMVA-10, from the chemical synthesis. GB-AX-BX-CX

Lubrication: Gas Admission valves.Status: Due to the lack of lubrication the valves burnt, each time

that happened there was a compressor downtime. Temp. Base: 300°C / Temp. Body: 150-250°C

Production: 100 ton/24 hr Methanol

Lubricant Solution: Krytox ® GPL 206 Consequences:

1.- Production Loss: 200 ton/per equip./per time

2.- Maintenance Intervention: 48 hrs3.- Personnel involved in repairs: 44.- Work labor cost: 10-15 USD/hr/person5.- Valve Cost: 1,200 USD each6.- Regular breakdowns every…: 2 weeks

Equipment: Couplings from the cooling tower. EF-401Lubrication: Two SKF 22220 BearingsConditions: RPM: 1800

Operation Temp.: 60°CHumidity: 100%Power: 150 H.P.

Status: Due to the excess water in the process there was some water washout that brought eventually lack of lubrication hence, equipment breakdown.

Lubricant Solution: Krytox ® GPL 206 Consequences:

1.- Cooling Tower Downtime: Immediate shutdown of Methanol production

2.- Production Loss: 600 ton per shift3.- Maintenance Intervention: 144 hrs4.- Personnel Involved in repairs: 85.- Work labor cost: 10-15 USD/hr/person6.- Bearing Cost: 200 USD each

Equipment: Couplings from the Forced Flow Fan in the reformer furnace. GB-101

Lubrication: Two SKF 22220 BearingsConditions: RPM: 3600

Operation Temp : 140°CPower: 150 H.P.

Status: Due to the constant high temperature in the process there was the risk of grease melting that could

eventually become a lack of lubrication.

Lubricant Solution: Krytox ® GPL 206 Consequences:

1.- Breakdown.: Immediate shutdown of Methanol

production1.- Production Loss : 500 ton per shift2.- Maintenance Intervention : 120 hrs3.- Personnel Involved in repairs : 84.- Work labor cost : 10-15 USD/hr/person5.- Bearing Cost : 200 USD each

Equipment: Turbine Engine WaukeshaLubrication: Spark PlugConditions: High Temperature.

High dielectric rigidityStatus: Waukesha recommends Krytox® GPL 206 due it's engine

works at extreme conditions and Krytox® increase the motor electrical system useful-life .

This Kind of motors are more frequently in the south of our country where are oil well to extract gas to use it as motor combustible.

Lubricant Solution: Krytox ® GPL 206

Consequences:Depends on the engine application

Equipment: Distillation TowerLubrication: BearingsConditions: Vacuum Pressure 1.2 mmHg

Temperature: 350-400°CStatus: Due high temperature and low pressure the used grease

should support these conditions and should not degrade in order to avoid equipment rupture and breakdown
