✶

3.6

Sample coolers shall be designed for the pressure/temperature conditions of the stream being sampled. Materials of construction shall be suitable for the process fluid. Sample coolers shall be used as required to cool the sample to 140°F (60°C) or lower, but: (1) not below a temperature that would result in a viscosity greater than 500 cP, and (2) not to a temperature less than 25°F (14°C) above the pour point and the freezing point of the sample. Coolers for tar, asphalt, and residuum shall use co-current flow of water and the fluid being sampled, and a water preheater, to avoid plugging of the cooler. Sample system heaters. With fluids having a pour point or a freezing point above the lowest ambient design temperature, or having a viscosity greater than 500 cP at the lowest ambient design temperature, facilities shall be provided to heat the sampling system to 25°F (14°C) above the pour point and the freezing point of the sample to assure its flow into the sample container.

LIGHTING O

3.7

➧

A minimum in-service illumination level of 20 ft candles (215 lux) shall be provided for sampling facilities. If lighting is provided specifically for the sampling system, a local switch shall be provided.

SAMPLE CONNECTIONS S,O

4.4 4.5

The final locations of sample points shall be governed by the following considerations for personnel safety and accessibility: a. They shall be convenient to normal operating locations as far as practicable. b. The sample points shall preferably be accessible from ground level. If this is not practical, they shall be accessible from permanent platforms. c. At least two escape routes shall be available for personnel. d. They shall allow personnel to stand upwind, based on the prevailing wind pattern. e. They are not to be in areas of possible contamination if a spill of a hazardous material should occur (e.g., they shall not be in areas inside pump toewalls). Sample tap positioning shall be per the following: a. Liquid or gas streams. Sample taps shall not be closer than 20 pipe diameters downstream or 10 pipe diameters upstream from the junction of two streams. Where two-phase flow can exist, sample taps shall be no closer than 12 pipe diameters downstream from a pressure reducer. b. Fluidized solids streams. Sample taps shall not be closer than 8 pipe diameters downstream or 2 pipe diameters upstream from a junction of two fluidized solids streams, an elbow, valve, or other flow disruption. Sample tap orientation shall be per the following: a. Sample taps should be installed in vertical lines with upward liquid flow and downward vapor flow. b. When sample taps are installed in horizontal lines, side entry of probe is preferred. Process vents and drains shall not be used as sample connections. Sample connections shall not be used for the installation of indicators or other instruments that are extraneous to the sampling operation.

PIPING DESIGN S

5.1

S

5.2

Sample piping shall be as short as possible and shall be adequately supported and braced to minimize the probability of it being damaged by vibration, accidental impact, or reaction forces caused by valve operation. Soft sealed ball and plug valves shall not be used as block valves on lines discharging to the atmosphere.

MATERIALS R

✶

5.3

All valves in liquid and gas sampling systems shall be Type 304 or Type 316 stainless steel, unless other materials of construction are required because of the fluid to be sampled.
