On chemical plants and oil refineries, steam, nitrogen, compressed air. lubricating oil, and other utility systems are responsible for a disproportionately large number of accidents. Flammable oils are recognized as a hazard, but services are given less attention. If the modification to the lubricating system had been systematically studied before it was made, as recommended in Chapter 2, a larger vent could have been installed, or a pipe-break and funnel could have been installed at the inlet to the sump. 

A standard laboratory cylinder is about 5 ft high with an internal vessel diameter of about 6 in. Determine the total energy of explosion for this cylinder if it contains nitrogen compressed to 2500 psig. Assume initial and ambient conditions of 298 K and 1 atm.

Auxiliary systems which exist in the HCF include material handling equipment (cranes hoists, transporters, etc.), low pressure nitrogen, compressed air, hydraulic systems, process waste water collection system, rainwater collection drains, communications systems, and oxygen monitors. Additionally, HCF activities are supported by operations in B6595, B6596, and B6597.

MTR has also brilliantly used membranes for the recovery of olefins from the polyolefin polymerization processes. In this process, schematic of which is shown in Figure 8.9, the vent gases from the polymerization process which contains hydrocarbons and nitrogen compressed, condensed to recover liquid hydrocarbons and then fed to a membrane separator to recover olefins which are recompressed and condensed. The commercial offering of this process is done under the trade name VaporSep and is used by polyolefin producers like ExxonMobil, Formusa Plastics, SABIC and Sinopec. MTR has similar processes for propylene, vinyl chloride and ethylene oxide. 

A Tier 2 Process Safety Event (T-2 PSE) is a LOPC with lesser consequence. A T-2 PSE is an unplanned or uncontrolled release of any material, including nontoxic and nonflammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air), from a process that results in one or more of the consequences listed below and is not reported in Tier 1 ... 

Cylinders—Nitrogen-compressed gas cylinders come in various sizes and are made of high-strength steel. Equipped and maintained to ensure total safety, they are generally delivered to customers by a distributor using its own trucks. Cylinders are used for relatively low gas consumption requirements.
