Abstract
An expanded metal random packing for use in gas-liquid or liquid-liquid contact devices, which packing comprises: a longitudinal strip of expanded metal characterized by a plurality of generally uniformly disposed and defined spaces, the spaces defined by a plurality of struts hav ing a one and an other end, and the ends of said longitudinal strip disposed inwardly about a vertical axis to form a partial or fully enclosed body of an expanded metal random packing.
Claims31
A random packing for gas-liquid or liquid-liquid contact, which packing consists essentially of:
- (a) a longitudinal strip of expanded sheet material having a one end and another end and having at least three generally uniform linearly disposed spaces in said strip, in the form of only one to about two full rows, wherein there is at least one full row of enclosed spaces, said strip having struts defining said spaces, and said struts having a one and an other end;
- and
- (b) the ends of said longitudinal strip disposed about a vertical axis generally perpendicular to the longitudinal axis of said strip to form a partially or fully enclosed packing body.
A random packing for gas-liquid or liquid-liquid contact which packing comprises:
- (a) a longitudinal strip of expanded sheet metal material having one and an other end and having from 3 to 12 generally uniform, linearly disposed and defined spaces in said strip, said strip having only one full row of enclosed spaces of uniform width, said strip having substantially uniformly wide struts to define said spaces, the struts having a one and an other end to form drip points;
- and
- (b) the ends of said strip disposed inwardly about a vertical axis generally perpendicular to the longitudinal axis of said strip to form a partial or fully enclosed packing body, and all of the one and other ends of the struts disposed inwardly toward the said vertical axis.
A method of forming a random packing of expanded sheet material for gas-liquid or liquid-liquid contact, which method comprises:
- (a) forming a longitudinal strip having a one and other end and having at least three, generally uniform, linearly disposed spaces in said strip, in the form of only one to two rows, with at least one row of fully enclosed spaces, said strip having struts to define said spaces and the struts having a one and an other end;
- and
- (b) forming said strip about a vertical axis to direct the one and other ends of said strip generally toward each other and generally perpendicular to the axis of said strip, to form a packing body having partially or fully enclosed space within said strip.
A random packing body for use in a fluid contact device, which body comprises:
- (a) a plurality of uniformly narrow struts having a one end and other end to form drip points and said struts forming a network of struts which surround and define a plurality of generally uniform spaces;
- (b) connecting means connecting said struts to adjacent struts to form a chain of said network;
- (c) at least three of said spaces disposed about a vertical axis of rotation to form a partially or fully enclosed packing body, said axis generally perpendicular to a plane containing said connecting means and defining strut ends above and below said plane;
- and
- (d) the one strut ends disposed sequentially inwardly and outwardly above said plane and the corresponding other strut ends below said plane are disposed sequentially outwardly and inwardly with respect to the said axis to form a star-shaped packing body.
A random packing body for use in a fluid contact device, which body comprises:
- (a) a plurality of uniformly narrow struts having a one end and an other end to form drip points and said struts forming a network of struts which surround and define a plurality of generally uniform spaces;
- (b) connecting means connecting such struts to adjacent struts to form a chain of said network;
- (c) at least three of said spaces disposed about a vertical axis of rotation to form a packing body, said axis generally perpendicular to a plane containing said connecting means and defining strut ends above and below said plane;
- and
- (d) the one and the other strut ends all disposed inwardly toward the said axis of rotation to form a generally spheroidal packing body,
- (e) and wherein the one strut ends above said planes are disposed sequentially inwardly toward said axis at an angle of about or approaching 90.degree., and the other strut ends are disposed inwardly towrd said axis at an angle of less than or approaching 90.degree. to form a fully enclosed spheroidal-type packing body.
