Drain Systems

Drain systems are used to safely dispose of all liquids spilled, drained from equipment or resulting from wash down activities. Separate drainage systems for drainage water from process areas that could be contaminated with oil (closed drains) and drainage water from non-process areas (open drains) should be available to the extent practical. All process areas should be bundled to ensure drainage water flows into the closed drainage system and that uncontrolled contaminated surface run-off is avoided.

Drainage tanks and slop tanks are designed with sufficient capacity for foreseeable operating conditions, and systems to prevent overfilling should be installed.  Drip trays, or other controls, should be used to collect run-off from equipment that is not contained within a bundled area and the contents routed to the closed drainage system.  Storm water flow channels and collection ponds installed as part of the open drainage system should be fitted with oil / water separators.  Storm water runoff should be treated through an oil / water separation system.

This course will give participants an understanding of the safe operation, and hazards associated with drain systems found in the oil and gas industry.

Day 1
Drain Systems Overview

  1. Surface Water Drainage (Open and Closed Systems)
  2. Equipment Oily Water Drainage (Closed System)
  3. Layout, capacity, isolation and sectioning
  4. Interface requirements
  5. Safety and environmental requirements

On day 1, participants will have obtained an overall understanding of industrial drain systems, associated components, and equipment such as fire stops, catch basins, vents and sealing requirements.  System layout including network design as well as segregation of drainage materials will also be discussed.  Operating, maintenance and safety procedures for open drain systems will be reviewed while stressing safety and environmental compliance and concerns.

 

Day 2
Closed drain and oily water treatment

  1. Commissioning requirements
  2. Principles of operation, treatment and handling
  3. Inlet and outlet facilities
  4. Operational and maintenance requirements
  5. Safety and environmental requirements

On day 2, participants will have gained an understanding of the configuration, scope and operation of closed drainage systems. System activities with respect to commissioning, normal operation, emergency shut down requirements and maintenance will also be covered.  Oil recovery and drain water treatment, will also be discussed while paying particular attention to health, safety and environmental compliance.

This course is mainly targeted to process technicians, process technologists and maintenance personnel. The course can also be applicable to employees working with equipment and materials purchasing, equipment procurement, job planning as well as immediate supervisors to the working technicians.
