A: Remember that every member - officer or not - has a right to attend meetings as long as he is not disruptive. If a member does disrupt a meeting, the presiding officer should first warn him, then, if his offense continues, call him to order, saying something like "The member is out of order and will be seated." Or, another member can say, "Mr. President, I call the member to order," after which the President could declare the offender out of order and tell him to be seated.

If this still doesn't work, the President can "name" the offender (which is like prefering charges). Again, if the offense continues, the President will state, "Mr. Jones has been warned several times about his behavior, yet continues. What penalty shall be imposed on the member?" The assembly will then vote on suggested penalties, which may include leaving the meeting, as you suggest. Expulsion from membership requires a two-thirds vote, but the lesser penalties require only a majority. If several penalties are suggested, start with the most severe, continuing until one receives the required vote. See RONR pp. 640-42.
